PLoS One 2017; 12:e0168938. [PMID: 28068430 PMCID: PMC5222621 DOI: 10.1371/journal.pone.0168938] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2016] [Accepted: 12/08/2016] [Indexed: 01/05/2023] Open
Abstract
P-glycoprotein (Pgp) is a membrane bound efflux pump spread in a variety of tumor cells and considered as a main component of multidrug resistance (MDR) to chemotherapies. In this work, three groups of compounds (imidazolone, oxazolone and vinyl dipeptide derivatives) were synthesized aiming to develop a molecular framework that effectively suppresses MDR. When tested for their influence on Pgp activity, four compounds coded Cur1-01, Cur1-12V, Curox-1 and Curox-3 significantly decreased remaining ATP concentration indicating Pgp substrate site blocking. On the other hand, Cur-3 and Cur-10 significantly increased remaining ATP concentration, which is indicative of Pgp ATPase inhibition. The cytotoxicity of synthesized compounds was examined against Pgp expressing/highly resistant colorectal cancer cell lines (LS-174T). Compounds Cur-1 and Cur-3 showed considerable cytotoxicity with IC50 values of 7.6 and 8.9 μM, respectively. Equitoxic combination (at IC50 concentrations) of PTX and Cur-3 greatly diminished resistant cell clone from 45.7% to 2.5%, albeit with some drop in potency from IC50 of 7.9 nM to IC50 of 23.8 nM. On the other hand, combination of PTX and the non-cytotoxic Cur1-12V (10 μM) significantly decreased the IC50 of PTX to 3.8 nM as well as the resistant fraction to 16.2%. The combination test was confirmed using the same protocol but on another resistant CRC cell line (HCT-116) as we obtained similar results. Both Cur-3 and Cur1-12V (10 μM) significantly increased the cellular entrapment of Pgp probe (doxorubicin) elevating its intracellular concentration from 1.9 pmole/cell to 3.0 and 2.9 pmole/cell, respectively.

Abstract
Geniposide is a water-soluble iridoid glucoside with anti-oxidant and anti-inflammatory biological functions. It has been indicated that geniposide may increase doxorubicin (DOX) accumulation in drug-resistant tumor cells. The present study aimed to investigate the resistance-reversing effect of geniposide in DOX-resistant cells and assess the underlying mechanisms of its action. The results revealed that geniposide itself weakly inhibited tumor cell growth. Furthermore, geniposide effectively reversed DOX resistance in a dose-dependent manner in human osteosarcoma DOX-resistant (MG63/DOX) cells. The action of geniposide was confirmed by increased accumulation of intracellular DOX detected in MG63/DOX cells. Notably, geniposide enhanced the efficacy of DOX against MG63/DOX cancer cell-derived xenografts in nude mice. To study the mechanism, intracellular accumulation of rhodamine 123 was measured using flow cytometry. At concentrations that reversed multidrug resistance (MDR), geniposide significantly downregulated P-glycoprotein (P-gp) expression. Therefore, geniposide reverses P-gp-mediated MDR by reducing the expression of P-gp and its transport function. The present study therefore indicated that geniposide may be administered in combination with conventional anti-neoplastic drugs to prevent MDR.

Abstract
Multidrug resistance (MDR) presents a serious challenge to the efficiency of cancer treatment, and may be associated with the overexpression of drug efflux pumps. P-glycoprotein (P-gp) is a drug efflux pump often found overexpressed in cases of acquired MDR. Nevertheless, there are no P-gp inhibitors being used in the current clinical practice, due to toxicity problems, drug interactions, or pharmacokinetic issues. Therefore, it is important to identify novel inhibitors of P-gp activity or expression. Curcumin is a secondary metabolite isolated from the turmeric of Curcuma longa L. which has been associated with several biological activities, particularly P-gp modulatory activity (by inhibiting both P-gp function and expression). However, curcumin shows extensive metabolism and instability, which has justified the recent and intensive search for analogs of curcumin that maintain the P-gp modulatory activity but have enhanced stability. This review summarizes and compares the effects of curcumin and several curcumin analogs on P-glycoprotein function and expression, emphasizing the potential of these molecules for the possible development of safe and effective inhibitors of P-gp to overcome MDR in human cancer.

Abstract
Multidrug resistance (MDR) is a major obstacle for successful chemotherapy treatment. Searching for effective MDR modulators and combining them with anticancer drug therapies has been a promising strategy against clinical MDR. In our previous study, we have found that DHA-E3, a synthetic derivative of DHA, has the ability to modulate the function of P-glycoprotein (P-gp) and reverse MDR in cancer cells. In this study, we further evaluated the reversal effect of DHA-E3 on MDR and explored its mechanism of action in vitro. Our findings showed that DHA-E3 significantly potentiated the cytotoxicity of vincristine(VCR) and adriamycin(ADR) in the P-gp over-expressing KB/VCR and A02 cells. The mechanistic study found that DHA-E3 increased the intracellular accumulation of ADR and rhodamine-123 by directly inhibiting the drug-transport activity of P-gp. In the present study, we found that DHA-E3 not only reversed MDR, but also induced autophagy in MDR cancer cells. To determine whether DHA-E3-induced autophagy is an adaptive survival response or contributes to cell death, we manipulated autophagic activity using autophagy inhibitor 3-MA or siRNA targeting Beclin1. We found that the reversal activity of DHA-E3 was significantly exacerbated in the presence of 3-MA or blocking the expression of Beclin1. These results suggest that DHA-E3 is capable of reversing MDR, induction of autophagy represents a defense mechanism and inhibiting this process may be an effective strategy to augment the reversal activity of reversal agents.

Abstract
The incidence of esophageal carcinoma is increasing throughout the world. A major obstacle to its treatment is acquired multidrug resistance (MDR) which results in the failure of chemotherapy and patient relapse. Here, we identified that ouabain is capable of reversing MDR to cisplatin (CDDP) in EC109/CDDP cells and explore the possible mechanisms of action. The parental and the MDR cell lines were both sensitive to ouabain with 50 % inhibitory concentration (IC50) values of 258.11 and 710.63 nM, respectively. Cisplatin cytotoxicity increased in the EC109/CDDP cells by the addition of ouabain which helps promote CDDP-induced apoptosis. Ouabain at 20 nM effectively reduced the IC50 of CDDP in EC109/CDDP cells from 36.54 to 3.39 μM. This represents a 10.78-fold increase in sensitization to CDDP. We also found that ouabain was capable of down regulating the expression of P-glycoprotein (P-gp) and Bcl-2 in a dose- and time-dependent manner. Finally, the results indicated that ouabain suppressed Wnt luciferase report (TOPFlash) activity obviously in EC109/CDDP and depressed the translocation of β-catenin into the nucleus. Moreover, ouabain showed reversal effect of MDR to CDDP in nude mouse xenograft model, and reduced the protein level of β-catenin (Y333) in tumor tissue of CDDP plus ouabain group. All data proved that ouabain has a potent β-catenin-dependent anti-MDR effect.

Abstract
In the present study, a total of 25 novel ningalin B analogues were synthesized and evaluated for their P-gp modulating activity in a P-gp overexpressed breast cancer cell line LCC6MDR. Preliminary structure-activity study shows that A ring and its two methoxy groups are important pharmacophores for P-gp inhibiting activity. Among all derivatives, 23 is the most potent P-gp modulator with EC50 of 120-165 nM in reversing paclitaxel, DOX, vinblastine and vincristine resistance. It is relatively safe to use with selective index at least greater than 606 compared to verapamil. Mechanistic study demonstrates that compound 23 reverses P-gp mediated drug resistance by inhibiting transport activity of P-gp, thereby restoring intracellular drug accumulation. In summary, our study demonstrates that ningalin B analogue 23 is a non-cytotoxic and effective P-gp chemosensitizer that can be used in the future for reversing P-gp mediated clinical cancer drug resistance.

Abstract
Curcumin, a natural polyphenol exhibits chemopreventive and chemotherapeutic activities towards cancer. In order to improve the bioavailability and therapeutic efficacy, curcumin is encapsulated in alginate aldehyde-gelatin (Alg Ald-Gel) nanogels. Alginate aldehyde-gelatin nanogels are prepared by inverse miniemulsion technique. Physicochemical properties of the curcumin loaded nanogels are evaluated by, Dynamic light scattering (DLS), NMR spectroscopy and Scanning electron microscopy (SEM). Curcumin loaded nanogels show hydrodynamic diameter of 431±8nm and a zeta potential of -36±4mV. The prepared nanogels exhibit an encapsulation efficiency of 72±2%. In vitro drug release studies show a controlled release of curcumin from nanogels over a period of 48h. Hemocompatibility and cytocompatibility of the nanogels are evaluated. Bare nanogels are cytocompatible and curcumin loaded nanogels induce anticancer activity towards MCF-7 cells. In vitro cellular uptake of the curcumin loaded nanogels using confocal laser scanning microscopy (CLSM) confirms the uptake of nanogels in MCF-7 cells. Hence, the developed nanogel system can be a suitable candidate for curcumin delivery to cancer cells.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2016; 23:316-323. [PMID: 26969385 DOI: 10.1016/j.phymed.2016.01.008] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2015] [Revised: 01/08/2016] [Accepted: 01/13/2016] [Indexed: 06/05/2023]
Abstract
BACKGROUND The issue of multidrug resistance (MDR) cancer is one of the major barriers to successful chemotherapy treatment. The ATP-binding cassette (ABC) efflux transporters play an important role in the chemotherapeutic failure. Several generations of ABC efflux transporter inhibitors have been developed, however, none of them could provide better clinical outcome due to systemic toxicities and significant drug-drug interactions. Therefore, the present study focused on identifying the effect of the natural carotenoid on ABC transporters and may provide a safer choice to defeat MDR cancer. PURPOSE The aim of the present study was to evaluate the inhibitory potency of β-carotene on the ABC efflux transporters, as well as the reversal effect of β-carotene toward MDR cancers. The underlying molecular mechanisms and inhibitory kinetics of β-carotene on the major ABC efflux transporter, P-glycoprotein, were further investigated. METHODS The human P-gp (ABCB1/Flp-In(TM)-293), MRP1 (ABCC1/Flp-In(TM)-293) and BCRP (ABCG2/Flp-In(TM)-293) stable expression cells were established by using the Flp-In(TM) system. The cytotoxicity of β-carotene was evaluated by MTT assay in the established cell lines, sensitive cancer cell lines (HeLaS3 and NCI-H460) and resistant cancer cell lines (KB-vin and NCI-H460/MX20). Surface protein detection assay and eFluxx-ID Green Dye assay were applied for confirmation of surface expression and function of the transporters. The transporter inhibition potency of β-carotene was evaluated by calcein-AM uptake assay and mitoxantrone accumulation assay. Further interaction kinetics between β-carotene and P-gp were analyzed by rhodamine123 and doxorubicin efflux assay. The influence of β-carotene on ATPase activity was evaluated by Pgp-Glo(TM) Assay System. RESULTS Among the tested ABC efflux transporters, β-carotene significantly inhibited human P-gp efflux function without altering ABCB1 mRNA expression. Furthermore, β-carotene stimulated both P-gp basal ATPase activity and the verapamil-stimulated P-gp ATPase activity. In addition, β-carotene exerted partially inhibitory effect on BCRP efflux function. The combination of β-carotene and chemotherapeutic agents significantly potentiated their cytotoxicity in both cell stably expressed human P-gp (ABCB1/Flp-In(TM)-293) and MDR cancer cells (KB-vin and NCI-H460/MX20). CONCLUSION The present study indicated that β-carotene may be considered as a chemo-sensitizer and regarded as an adjuvant therapy in MDR cancer treatment.

[PMID: 27452633 DOI: 10.1016/j.dmpk.2016.02.005] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2015] [Revised: 01/23/2016] [Accepted: 02/13/2016] [Indexed: 11/20/2022]
Abstract
Curcumin can synergistically enhance docetaxel's in vitro and in vivo antitumor activity and has been co-administrated with docetaxel in clinical trials. The aim of our study is to investigate the effect of curcumin on the pharmacokinetics of docetaxel and explore its mechanism on OATP1B1, OATP1B3 and human liver microsomes (HLMs). In rats, curcumin increased the docetaxel area under the plasma concentration-time curve (AUC0-8h) and the terminal half-life (t1/2) to 1.86- and 1.55-fold, respectively. Moreover, curcumin decreased the clearance (CL) of docetaxel to 52.1%. Human embryonic kidney 293 (HEK293) cells stably expressing OATP1B1 and OATP1B3 were used to observe the effects of curcumin on OATP1B1 and OATP1B3-mediated uptake of docetaxel. Curcumin exhibited potent inhibition on OATP1B1 and OATP1B3-mediated docetaxel uptake with IC50 values of 3.81 ± 1.19 μM and 33.70 ± 1.22 μM, respectively. The inhibition of curcumin on docetaxel metabolism in HLMs indicated that curcumin can modestly inhibit the metabolism of docetaxel with the IC50 value of 22.70 ± 1.13 μM and Ki value of 24.72 ± 4.24 μM. The preclinical and clinical improved docetaxel's therapeutic efficacy when co-administrated with curcumin may be due to the inhibition of curcumin on OATP1B1, OATP1B3 and HLMs activities. Close attention should be paid when combined treatment with docetaxel and curcumin carried out clinically.

Abstract
The liver is the center for drug and xenobiotic metabolism, which is influenced most with medication/xenobiotic-mediated toxic activity. Drug-induced hepatotoxicity is common and its actual frequency is hard to determine due to underreporting, difficulties in detection or diagnosis, and incomplete observation of exposure. The death rate is high, up to about 10% for drug-induced liver damage. Endorsed medications represented >50% of instances of intense liver failure in a study from the Acute Liver Failure Study Group of the patients admitted in 17 US healing facilities. Albeit different studies are accessible uncovering the mechanistic aspects of medication prompted hepatotoxicity, we are in the dilemma about the virtual story. The expanding prevalence and effectiveness of Ayurveda and natural products in the treatment of various disorders led the investigators to look into their potential in countering drug-induced liver toxicity. Several natural products have been reported to date to mitigate the drug-induced toxicity. The dietary nature and less adverse reactions of the natural products provide them an extra edge over other candidates of supplementary medication. In this paper, we have discussed the mechanism involved in drug-induced liver toxicity and the potential of herbal antioxidants as supplementary medication.

Chem Biol Interact 2015; 244:140-8. [PMID: 26689174 DOI: 10.1016/j.cbi.2015.12.001] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2015] [Revised: 11/30/2015] [Accepted: 12/10/2015] [Indexed: 01/06/2023]
Abstract
Curcumin analogs were synthesized and their multi-drug resistance (MDR) reversing properties were determined in human MDR leukemic (K562/Adr) cells. Four analogs, 1,7-bis-(3,4-dimethoxy-phenyl)-hepta-1,6-diene-3,5-dione (1J), 2,6-bis-(4-hydroxy-3-methoxy-benzylidene)-cyclohexanone (2A), 2,6-bis-(3,4-dihydroxy-benzylidene)-cyclohexanone (2F) and 2,6-bis-(3,4-dimethoxy-benzylidene)-cyclohexanone (2J) markedly increased the sensitivity of K562/Adr cells to paclitaxel (PTX) for 8-, 2-, 8- and 16- folds, respectively and vinblastine (Vin) for 5-, 3-, 12- and 30- folds, respectively. The accumulation of P-gp substrates, Calcein-AM, Rhodamine 123 and Doxorubicin, was significantly increased by 1J (up to 6-, 11- and 22- folds, respectively) and 2J (up to 7-, 12- and 17- folds, respectively). Besides 2A, 2F and 2J dramatically decreased P-gp expression in K562/Adr cells. These results could be summarized in the following way. Analog 1J inhibited only P-gp function, while 2A and 2F inhibited only P-gp expression. Interestingly, 2J exerts inhibition of both P-gp function and expression. The combination index (CI) of combination between 2J and PTX (0.09) or Vin (0.06) in K562/Adr cells indicated strong synergistic effects, which likely due to its MDR reversing activity. Moreover, these analogs showed less cytotoxicity to peripheral mononuclear cells (human) and red blood cells (human and rat) suggesting the safety of analogs for further animal and clinical studies.

Curcumin Affects Phase II Disposition of Resveratrol Through Inhibiting Efflux Transporters MRP2 and BCRP. Pharm Res 2015; 33:590-602. [PMID: 26502886 DOI: 10.1007/s11095-015-1812-1] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2015] [Accepted: 10/20/2015] [Indexed: 10/22/2022]
Abstract
PURPOSE To evaluate the impact of curcumin on the disposition of resveratrol phase II metabolites in vivo, and explain the observations by performing in vitro studies in transporter-overexpressed cells. METHODS Pharmacokinetic studies of resveratrol with and without the co-administration of curcumin were performed in both FVB wild-type and Bcrp1 (-/-) mice. Human UGT1A9-overexpressing HeLa cells and human MRP2-overexpressing MDCK II-UGT1A1 cells were used as in vitro tools to further determine the impact of curcumin as a transporter inhibitor on resveratrol metabolites. RESULTS We observed higher exposure of resveratrol conjugates in Bcrp1 (-/-) mice compared to wild-type mice. In wild-type mice, curcumin increased the AUC of resveratrol glucuronide by 4-fold compared to the mice treated without curcumin. The plasma levels of resveratrol and its sulfate conjugate also increased moderately. In Bcrp1 (-/-) mice, there was a further increase (6-fold increase) in AUC of resveratrol glucuronide observed when curcumin was co-administered compared to AUC values obtained in wild-type mice without curcumin treatment. In the presence of 50 nM curcumin, the clearance of resveratrol-3-O-glucuronide and resveratrol-3-O-sulfate reduced in both MRP2-overexpressing MDCKII-UGT1A1 cells and Human UGT1A9-overexpressing HeLa cells. CONCLUSIONS These results suggest that curcumin alters the phase II distribution of resveratrol through inhibiting efflux transporters including MRP2 and BCRP.

Abstract
BACKGROUND The encapsulation of curcumin (Cur) in polylactic-co-glycolic acid (PLGA) nanoparticles (Cur- NPs) was designed to improve its solubility and stability. Conjugation of the Cur-NPs with anti-P-glycoprotein (P-gp) antibody (Cur-NPs-APgp) may increase their targeting to P-gp, which is highly expressed in multidrug- resistance (MDR) cancer cells. This study determined whether Cur-NPs-APgp could overcome MDR in a human cervical cancer model (KB-V1 cells) in vitro and in vivo. MATERIALS AND METHODS First, we determined the MDR- reversing property of Cur in P-gp-overexpressing KB-V1 cells in vitro and in vivo. Cur-NPs and Cur-NPs-APgp, in the range 150-180 nm, were constructed and subjected to an in vivo pharmacokinetic study compared with Cur. The in vitro and in vivo MDR-reversing properties of Cur-NPs and Cur-NPs-APgp were then investigated. Moreover, the stability of the NPs was determined in various solutions. RESULTS The combined treatment of paclitaxel (PTX) with Cur dramatically decreased cell viability and tumor growth compared to PTX treatment alone. After intravenous injection, Cur-NPs-APgp and Cur-NPs could be detected in the serum up to 60 and 120 min later, respectively, whereas Cur was not detected after 30 min. Pretreatment with Cur-NPs-APgp, but not with NPs or Cur-NPs, could enhance PTX sensitivity both in vitro and in vivo. The constructed NPs remained a consistent size, proving their stability in various solutions. CONCLUSIONS Our functional Cur-NPs-APgp may be a suitable candidate for application in a drug delivery system for overcoming drug resistance. The further development of Cur-NPs-APgp may be beneficial to cancer patients by leading to its use as either as a MDR modulator or as an anticancer drug.

Abstract
The theory that several carcinogenetic processes are initiated and sustained by cancer stem cells (CSCs) has been validated, and specific methods to identify the CSCs in the entire population of cancer cells have also proven to be effective. This review aims to provide an overview of recently acquired scientific knowledge regarding phytochemicals and herbal extracts, which have been shown to be able to target and kill CSCs. Many genes and proteins that sustain the CSCs’ self-renewal capacity and drug resistance have been described and applications of phytochemicals able to interfere with these signaling systems have been shown to be operatively efficient both in vitro and in vivo. Identification of specific surface antigens, mammosphere formation assays, serial colony-forming unit assays, xenograft transplantation and label-retention assays coupled with Aldehyde dehydrogenase 1 (ALDH1) activity evaluation are the most frequently used techniques for measuring phytochemical efficiency in killing CSCs. Moreover, it has been demonstrated that EGCG, curcumin, piperine, sulforaphane, β-carotene, genistein and the whole extract of some plants are able to kill CSCs. Most of these phytochemicals act by interfering with the canonical Wnt (β-catenin/T cell factor-lymphoid enhancer factor (TCF-LEF)) pathway implicated in the pathogenesis of several cancers. Therefore, the use of phytochemicals may be a true therapeutic strategy for eradicating cancer through the elimination of CSCs.

Abstract
The increasing emergence of multidrug-resistant (MDR) cells presents a challenge to effective cancer therapy. Curcumin (CUR) has multifunctional anticancer properties, but its clinical use has been limited by poor solubility. We developed biodegradable polymeric micelles entrapping CUR in order to improve its antitumor activity and to explore whether it could treat MDR cells. This delivery system produced small micelles with a high encapsulation efficiency, good stability, and slow release of CUR. CUR micelles showed cytotoxic effects in wild-type drug-sensitive A2780s and in paclitaxel-resistant A2780t ovarian adenocarcinoma cells. The concentration of free CUR that reduced cell viability by 50% (IC50) was 1.5 fold and 1.2 fold higher than that of CUR micelles in A2780s and A2780t cells, respectively. Cellular uptake studies indicated that delivery by micelles improved CUR uptake into both cell lines. Cell cycle analysis suggested that CUR micelles induced apoptosis and enhanced G2/M arrest. Overall, CUR micelles may provide a novel strategy to improve the clinical management of MDR ovarian cancer.

Abstract
Curcuminoids are major components of Curcuma longa L., which is widely used as spice in food. This study aimed at identifying whether curcumin, demethoxycurcumin, and bisdemethoxycurcumin could modulate efflux function of human P-glycoprotein and be used as chemosensitizers in cancer treatments. Without altering P-glycoprotein expression levels and conformation, the purified curcuminoids significantly inhibited P-glycoprotein efflux function. In rhodamine 123 efflux and calcein-AM accumulation assays, demethoxycurcumin demonstrated the highest inhibition potency (inhibitory IC50 = 1.56 ± 0.13 μM) among the purified curcuminoids, as well as in the fold of reversal assays. Demethoxycurcumin inhibited P-glycoprotein-mediated ATP hydrolysis under concentrations of <1 μM and efficiently inhibited 200 μM verapamil-stimulated ATPase activity, indicating a high affinity of demethoxycurcumin for P-glycoprotein. These results suggested that demethoxycurcumin may be a potential additive natural product in combination with chemotherapeutic agents in drug-resistant cancers.

Abstract
Curcumin (CUR) is a phytochemical that inhibits the xenobiotic ABC efflux transporters implicated in cancer multidrug resistance (MDR), such as P-glycoprotein (P-gp), breast cancer resistance protein (BCRP) and multidrug resistance-associated proteins 1 and 5 (MRP1 and MRP5). The use of CUR in the clinic however, is complicated by its instability and poor pharmacokinetic profile. Monocarbonyl analogs of CUR (MACs) are compounds without CUR's unstable β-diketone moiety and were reported to have improved stability and in vivo disposition. Whether the MACs can be used as MDR reversal agents is less clear, as the absence of a β-diketone may negatively impact transporter inhibition. In this study, we investigated 23 heterocyclic cyclohexanone MACs for inhibitory effects against P-gp, BCRP, MRP1 and MRP5. Using flow cytometry and resistance reversal assays, we found that many of these compounds inhibited the transport activity of the ABC transporters investigated, often with much greater potency than CUR. Overall the analogs were most effective at inhibiting BCRP and we identified three compounds, A12 (2,6-bis((E)-2,5-dimethoxy-benzylidene)cyclohexanone), A13 (2,6-bis((E)-4-hydroxyl-3-methoxybenzylidene)-cyclohexanone) and B11 (3,5-bis((E)-2-fluoro-4,5-dimethoxybenzylidene)-1-methylpiperidin-4-one), as the most promising BCRP inhibitors. These compounds inhibited BCRP activity in a non-cell line, non-substrate-specific manner. Their inhibition occurred by direct transporter interaction rather than modulating protein or cell surface expression. From these results, we concluded that MACs, such as the heterocyclic cyclohexanone analogs in this study, also have potential as MDR reversal agents and may be superior alternatives to the unstable parent compound, CUR.

Abstract
Resistance of solid tumors to treatment is significantly attributed to pharmacokinetic reasons at both cellular and multi-cellular levels. Anticancer agent must be bio-available at the site of action in a cytotoxic concentration to exert its proposed activity. P-glycoprotein (P-gp) is a member of the ATP-dependent membrane transport proteins; it is known to pump substrates out of cells in ATP-dependent mechanism. The over-expression of P-gp in tumor cells reduces the intracellular drug concentrations, which decreases the cytotoxicity of a broad spectrum of antitumor drugs. Accordingly, P-gp inhibitors/blockers are potential enhancer for the cellular bioavailability of several clinically important anticancer drugs such as, anthracyclines, taxanes, vinca alkaloids, and podophyllotoxins. Besides several chemically synthesized P-gp inhibitors/blockers, some naturally occurring compounds and plant extracts were reported for their modulation of multidrug resistance; however, this review will focus only on major classes of naturally occurring inhibitors viz., flavonoids, coumarins, terpenoids, alkaloids and saponins.

Abstract
This paper describes the formation of giant proteoliposomes containing P-glycoprotein (P-gp) from a solution of small proteoliposomes that had been deposited and partially dried on a film of agarose. This preparation method generated a significant fraction of giant proteoliposomes that were free of internalized vesicles, making it possible to determine the accessible liposome volume. Measuring the intensity of the fluorescent substrate rhodamine 123 (Rho123) inside and outside these giant proteoliposomes determined the concentration of transported substrates of P-gp. Fitting a kinetic model to the fluorescence data revealed the rate of passive diffusion as well as active transport by reconstituted P-gp in the membrane. This approach determined estimates for the membrane permeability coefficient (Ps) of passive diffusion and rate constants of active transport (kT) by P-gp as a result of different experimental conditions. The Ps value for Rho123 was larger in membranes containing P-gp under all assay conditions than in membranes without P-gp indicating increased leakiness in the presence of reconstituted transmembrane proteins. For P-gp liposomes, the kT value was significantly higher in the presence of ATP than in its absence or in the presence of ATP and the competitive inhibitor verapamil. This difference in kT values verified that P-gp was functionally active after reconstitution and quantified the rate of active transport. Lastly, patch clamp experiments on giant proteoliposomes showed ion channel activity consistent with a chloride ion channel protein that co-purified with P-gp. Together, these results demonstrate several advantages of using giant rather than small proteoliposomes to characterize transport properties of transport proteins and ion channels.

Abstract
A new polyoxypregnane aglycone, tenacigenin D (1), and seven new C21 steroid glycosides, tenacissimosides D-J (2-8), were isolated from the stems of Marsdenia tenacissima. Their structures were determined by interpretation of their 1D and 2D NMR and other spectroscopic data, as well as by comparison with published values for related known compounds. Compound 1 was found to circumvent P-glycoprotein (P-gp)-mediated multidrug resistance through an inhibitory effect on P-gp with a similar potency to verapamil. In addition, compound 1 potentiated the activity of erlotinib and gefitinib in epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI)-resistant non-small-cell lung cancer cells.

Abstract
Recently, a new class of multifunctional nanodroplets that combine the properties of polymeric drug carriers, ultrasound imaging contrast agents, and enhancers of ultrasound-mediated drug delivery has been developed. We studied the formation mechanism of nanodroplets of a drug and its application in chemotherapy. Curcumin was loaded in polymeric micelles as a anti-cancer drug using polyethylene glycol block-poly(caprolactone) with encapsulation efficiency of 95.60%. At room temperature, the developed systems comprised perfluorocarbon nanodroplets stabilized by walls comprising biodegradable block copolymers. Upon heating to 37°C, the nanodroplets were converted to nano/microbubbles. Under ultrasound, nanobubbles cavitated and collapsed, resulting in release of the encapsulated drug. The percentage release of curcumin-loaded nanodroplets by insonation was 90.95%, showing enhancement compared with the non-ultrasound group. Nanodroplets strongly retained the loaded drugs in vivo yet, under ultrasound-mediated vaporization, they released the drugs, thereby implementing effective targeting into the tumor. The tumor inhibition of the group in which curcumin-loaded nanodroplets were combined with ultrasound was 71.30%, more than that of the group of curcumin-loaded nanodroplets (53.00%). Nanodroplets showed high enhancement of anti-cancer effects under ultrasound. Upon intravenous injection, a long-lasting, strong and selective ultrasound contrast was observed, suggesting their coalescence into larger, highly echogenic microbubbles. These multifunctional nanodroplets, which manifest excellent therapeutic and ultrasound properties, could be promising anti-cancer drug delivery systems.

Abstract
This study examines the antitumor potential of curcumin and C6 ceramide (C6) against osteosarcoma (OS) cell lines when both are encapsulated in the bilayer of liposomal nanoparticles. Three liposomal formulations were prepared: curcumin liposomes, C6 liposomes and C6-curcumin liposomes. Curcumin in combination with C6 showed 1.5 times enhanced cytotoxic effect in the case of MG-63 and KHOS OS cell lines, in comparison with curcumin liposomes alone. Importantly, C6-curcumin liposomes were found to be less toxic on untransformed primary human cells (human mesenchymal stem cells) in comparison to OS cell lines. In addition, cell cycle assays on a KHOS cell line after treatment revealed that curcumin only liposomes induced G2/M arrest by upregulation of cyclin B1, while C6 only liposomes induced G1 arrest by downregulation of cyclin D1. C6-curcumin liposomes induced G2/M arrest and showed a combined effect in the expression levels of cyclin D1 and cyclin B1. The efficiency of the preparations was tested in vivo using a human osteosarcoma xenograft assay. Using pegylated liposomes to increase the plasma half-life and tagging with folate (FA) for targeted delivery in vivo, a significant reduction in tumor size was observed with C6-curcumin-FA liposomes. The encapsulation of two water insoluble drugs, curcumin and C6, in the lipid bilayer of liposomes enhances the cytotoxic effect and validates the potential of combined drug therapy.

Abstract
Overexpression of P-glycoprotein (P-gp) contributes to the multidrug resistance (MDR) phenotype found in many cancer cells. P-gp has been identified as a promising molecular target, although attempts to find successful therapies to counteract its function as a drug efflux pump have largely failed to date. Apart from its role in drug efflux, P-gp may have other cellular functions such as being involved in apoptosis, and is found in various locations in the cell. Its expression is highly regulated, namely by microRNAs (miRNAs or miRs). In addition, P-gp may regulate the expression of miRs in the cell. Furthermore, both P-gp and miRs may be found in microvesicles or exosomes and may be transported to neighboring, drug-sensitive cells. Here, we review this current issue together with recent evidence of this network of interactions between P-gp and miRs.

Abstract
Phospho-sulindac (PS) is a safe sulindac derivative with promising anticancer efficacy in colon cancer. We evaluated whether its combination with curcumin could enhance the efficacy in the treatment of lung cancer. Curcumin, the principal bioactive component in turmeric, has demonstrated versatile capabilities to modify the therapeutic efficacy of a wide range of anticancer agents. Here, we evaluated the effect of co-administration of curcumin on the anticancer activity of PS in a mouse xenograft model of human lung cancer. Curcumin enhanced the cellular uptake of PS in human lung and colon cancer cell lines. To assess the potential synergism between curcumin and PS in vivo, curcumin was suspended in 10% Tween-80 or formulated in micellar nanoparticles and given to mice by oral gavage prior to the administration of PS. Both formulations of curcumin significantly improved the pharmacokinetic profiles of PS, with the 10% Tween-80 suspension being much more effective than the nanoparticle formation. However, curcumin did not exhibit any significant modification of the metabolite profile of PS. Furthermore, in a mouse subcutaneous xenograft model of human lung cancer, PS (200 mg/kg) in combination with curcumin (500 mg/kg) suspended in 10% Tween-80 (51% inhibition, p<0.05) was significantly more efficacious than PS plus micelle curcumin (30%) or PS (25%) or curcumin alone (no effect). Consistent with the improved pharmacokinetics, the combination treatment group had higher levels of PS and its metabolites in the xenografts compared to PS alone. Our results show that curcumin substantially improves the pharmacokinetics of PS leading to synergistic inhibition of the growth of human lung cancer xenografts, representing a promising drug combination.

Abstract
Objective: To determine the possible interaction of curcumin with P-glycoprotein (P-gp) expression and function by in vitro and in silico studies. Materials and Methods: In this study, curcumin was compared for its potential to modulate the expression and function of P-gp in Y79 RB cells by western blot, RT-PCR (reverse transcription polymerase chain reaction) and functional assay. Further, in silico molecular modeling and docking simulations were performed to deduce the inhibitory binding mode of curcumin. Results: Western blot and RT-PCR analysis decreased the expression of P-gp in a dose-dependent manner. The effect of curcumin on P-gp function was demonstrated by Rhodamine 123 (Rh123) accumulation and efflux study. Curcumin increased the accumulation of Rh123 and decreased its efflux in retinoblastoma (RB) cells. In addition, curcumin inhibited verapamil stimulated ATPase activity and photoaffinity labeling study showed no effect on the binding of 8-azido-ATP-biotin, indicating its interaction at the substrate binding site. Moreover, molecular docking studies concurrently infer the binding of curcumin into the substrate binding site of P-gp with a binding energy of -7.66 kcal/mol. Conclusion: These findings indicate that curcumin suppresses the MDR1 expression and function, and therefore may be useful as modulators of multidrug resistance in RB tumor.

Abstract
The pleiotropic drug resistance network in budding yeast presents a first line of defense against xenobiotics, which is formed by primary and secondary active membrane transporters. Among these transporters, the ABC transporter Pdr5 is a key component, because it confers resistance against a broad spectrum of such cytotoxic agents. Furthermore, it represents a model system for homologous transporters from pathogenic fungi and has been intensively studied in the past. In addition to other mutational studies, the S1360F mutation of Pdr5 was found to modulate substrate specificity and resistance. Notably, in the S1360F background, the resistance against the immunosuppressant FK506 is drastically increased. We present a detailed analysis of this mutation that is located in the predicted cytosolic part of transmembrane helix 11. Our data demonstrate that kinetic and thermodynamic parameters of the S1360F mutant are similar to those of the wild-type protein, except for FK506-inhibited ATPase activity and the degree of competitive inhibition. In summary, our results indicate that the S1360F mutation within the transmembrane domain interferes drastically with the ability of the nucleotide-binding domains to hydrolyze ATP by interfering with interdomain crosstalk.

Abstract
Acquired chemotherapy resistance is a major contributor to treatment failure in oncology. For example, the efficacy of the common anticancer agent doxorubicin (DOX) is limited by the emergence of multidrug resistance (MDR) phenotype in cancer cells. While dose escalation of DOX can circumvent such resistance to a degree, this is precluded by the appearance of cardiotoxicity, a particularly debilitating condition in children. In vitro studies have established the ability of the natural phytochemical curcumin to overcome MDR; however, its widespread clinical application is restricted by poor solubility and low bioavailability. Building upon our recently developed polymer nanoparticle of curcumin (NanoCurc or NC) that significantly enhances the systemic bioavailability of curcumin, we synthesized a doxorubicin-curcumin composite nanoparticle formulation called NanoDoxCurc (NDC) for overcoming DOX resistance. Compared to DOX alone, NDC inhibited the MDR phenotype and caused striking growth inhibition both in vitro and in vivo in several models of DOX-resistant cancers (multiple myeloma, acute leukemia, prostate and ovarian cancers, respectively). Notably, NDC-treated mice also demonstrated complete absence of cardiac toxicity, as assessed by echocardiography, or any bone marrow suppression, even at cumulative dosages where free DOX and pegylated liposomal DOX (Doxil®) resulted in demonstrable attenuation of cardiac function and hematological toxicities. This improvement in safety profile was achieved through a reduction of DOX-induced intracellular oxidative stress, as indicated by total glutathione levels and glutathione peroxidase activity in cardiac tissue. A composite DOX-curcumin nanoparticle that overcomes both MDR-based DOX chemoresistance and DOX-induced cardiotoxicity holds promise for providing lasting and safe anticancer therapy.

Abstract
Broad spectrum therapeutic potential of curcumin is usually hampered by its photodegradation and low bioavailability. Present investigation was designed with an objective to develop transferrin-mediated solid lipid nanoparticles (Tf-C-SLN) resistant to the photostability and capable of enhancing the bioavailability by targeted drug delivery to elicit anticancer activity against SH-SY5Y neuroblastoma cells in vitro. Hot homogenization method was used for the formulation of Tf-C-SLN and evaluated physicochemically using parameters such as, size, zeta potential, entrapment efficiency and photostability, transmission electron microscopy (TEM), nuclear magnetic resonance (NMR), differential scanning colorimetry (DSC), and in vitro release study. In vitro cytotoxicity and apoptosis investigations were performed using microplate analysis and flow cytometry techniques. The physicochemical characterization confirmed the suitability of formulation method and various parameters therein. TEM investigation revealed the spherical morphology while NMR and DSC study confirmed the entrapment of curcumin inside the nanoparticles. The cytotoxicity, reactive oxygen species, and cell uptake were found to be increased considerably with Tf-C-SLN compared with curcumin-solubilized surfactant solution, and curcumin-loaded SLN (C-SLN) suggesting the targeting effect. AnnexinV-FITC/PI double staining, DNA analysis, caspase detection, and reduced mitochondrial potential confirmed the induction of apoptosis with nanoparticle treatment. Enhanced anticancer activity with Tf-C-SLN compared with curcumin-solubilized surfactant solution and C-SLN was observed from flow cytometry investigations with apoptosis being the major underlying mechanism. The in vitro observations of our investigation are very compelling and concrete to advocate the potential of Tf-C-SLN in enhancing the anticancer effect of curcumin against neuroblastoma in vivo and possible clinical applications.

Abstract
INTRODUCTION Multidrug resistance (MDR) is the main cause of failure in cancer therapy. One mechanism responsible for MDR is the active efflux of drugs by ATP-binding cassette (ABC) transporters. Several agents have been developed to block transporter-mediated drug efflux and some of these compounds have entered Phase II/III clinical testing. Evidence is also emerging of the role played by ABC transporters in cancer cell signalling that is likely to be important in disease progression and which is distinct from MDR. AREAS COVERED This article reviews current literature to analyse the rationale for targeting ABC transporters in cancer. Preclinical and clinical results of ABC transporter inhibitors in early clinical trials, as single agents or in combination with other drugs, are described. The development of new strategies to target MDR and the emerging roles of ABC transporters in cancer signalling are discussed. EXPERT OPINION The intense active search for safe and effective inhibitors of ABC transporters has led to some success in MDR reversal in preclinical studies. However, there has been little impact on clinical outcome. The discovery of novel, potent and nontoxic inhibitors as well as new treatment strategies is therefore needed.

Abstract
PURPOSE Colorectal cancer (CRC) is the third leading cause of cancer death in Taiwan; it ranks top three in the cancer mortality rate. Curcuminoids are derived from the rhizome of Curcuma longa. It has shown anti-cancer activity and apoptosis induction in a variety of cancer cell lines. This aims to study the potential of Poloxamer 407 as the thermogelling and mucoadhesive polymer for development of a site-targeting delivery system to enhance the localized delivery of curcuminoids to the colorectal cells for CRC chemotherapy. METHODS The mucoadhesive strength and rheological properties were measured as a function of poloxamer loaded with curcuminoids. RESULTS The gelation temperature of Poloxamer 407 was found to vary with its concentration and start gelling at 37°C at the concentration of 15.5% (w/v). To ensure gelation at physiological temperature after intra-rectal application, gelation temperature was determined by rheological measurement as well as by its physical appearance. The results indicated that its mucoadhesive strength also shows a dependency on temperature, which appears to be related to the increment in the maximum strength and average strength of the polymer. CONCLUSION The results have suggested that Poloxamer 407 could be a potential thermogelling and mucoadhesive polymer for the development of a site-targeting colorectal drug delivery system for curcuminoids in colorectal cancer therapy.

Abstract
Many prostate cancers relapse due to the generation of chemoresistance rendering first-line treatment drugs like paclitaxel (PTX) ineffective. The present study aims to determine the role of miRNAs and Hedgehog (Hh) pathway in chemoresistant prostate cancer and to evaluate the combination therapy using Hh inhibitor cyclopamine (CYA). Studies were conducted on PTX resistant DU145-TXR and PC3-TXR cell lines and clinical prostate tissues. Drug sensitivity and apoptosis assays showed significantly improved cytotoxicity with combination of PTX and CYA. To distinguish the presence of cancer stem cell like side populations (SP), Hoechst 33342 flow cytometry method was used. PTX resistant DU145 and PC3 cells, as well as human prostate cancer tissue possess a distinct SP fraction. Nearly 75% of the SP cells are in the G0/G1 phase compared to 62% for non-SP cells and have higher expression of stem cell markers as well. SP cell fraction was increased following PTX monotherapy and treatment with CYA or CYA plus PTX effectively reduced their numbers suggesting the effectiveness of combination therapy. SP fraction cells were allowed to differentiate and reanalyzed by Hoechst staining and gene expression analysis. Post differentiation, SP cells constitute 15.8% of total viable cells which decreases to 0.6% on treatment with CYA. The expression levels of P-gp efflux protein were also significantly decreased on treatment with PTX and CYA combination. MicroRNA profiling of DU145-TXR and PC3-TXR cells and prostate cancer tissue from the patients showed decreased expression of tumor suppressor miRNAs such as miR34a and miR200c. Treatment with PTX and CYA combination restored the expression of miR200c and 34a, confirming their role in modulating chemoresistance. We have shown that supplementing mitotic stabilizer drugs such as PTX with Hh-inhibitor CYA can reverse PTX chemoresistance and eliminate SP fraction in androgen independent, metastatic prostate cancer cell lines.

Effects of 3β-acethyl tormentic acid (3ATA) on ABCC proteins activity. Int J Mol Sci 2012; 13:6757-6771.

Abstract
Multidrug resistance (MDR) is considered the main cause of cancer chemotherapy failure and patient relapse. The active drug efflux mediated by transporter proteins of the ABC (ATP-binding cassette) family is the most investigated mechanism leading to MDR. With the aim of inhibiting this transport and circumventing MDR, a great amount of work has been dedicated to identifying pharmacological inhibitors of specific ABC transporters. We recently showed that 3β-acetyl tormentic acid (3ATA) had no effect on P-gp/ABCB1 activity. Herein, we show that 3ATA strongly inhibited the activity of MRP1/ABCC1. In the B16/F10 and Ma104 cell lines, this effect was either 20X higher or similar to that observed with MK571, respectively. Nevertheless, the low inhibitory effect of 3ATA on A549, a cell line that expresses MRP1-5, suggests that it may not inhibit other MRPs. The use of cells transfected with ABCC2, ABCC3 or ABCC4 showed that 3ATA was also able to modulate these transporters, though with an inhibition ratio lower than that observed for MRP1/ABCC1. These data point to 3ATA as a new ABCC inhibitor and call attention to its potential use as a tool to investigate the function of MRP/ABCC proteins or as a co-adjuvant in the treatment of MDR tumors.

Abstract
AIM To compare the anti-cancer activity and cellular uptake of curcumin (Cur) delivered by targeted and non-targeted drug delivery systems in multidrug-resistant cervical cancer cells. METHODS Cur was entrapped into poly (DL-lactide-co-glycolide) (PLGA) nanoparticles (Cur-NPs) in the presence of modified-pluronic F127 stabilizer using nano-precipitation technique. On the surface of Cur-NPs, the carboxy-terminal of modified pluronic F127 was conjugated to the amino-terminal of anti-P-glycoprotein (P-gp) (Cur-NPs-APgp). The physical properties of the Cur-NPs, including particle size, zeta potential, particle morphology and Cur release kinetics, were investigated. Cellular uptake and specificity of the Cur-NPs and Cur-NPs-APgp were detected in cervical cancer cell lines KB-V1 (higher expression of P-gp) and KB-3-1 (lower expression of P-gp) using fluorescence microscope and flow cytometry, respectively. Cytotoxicity of the Cur-NPs and Cur-NPs-APgp was determined using MTT assay. RESULTS The particle size of Cur-NPs and Cur-NPs-APgp was 127 and 132 nm, respectively. The entrapment efficiency and actual loading of Cur-NPs-APgp (60% and 5 μg Cur/mg NP) were lower than those of Cur-NPs (99% and 7 μg Cur/mg NP). The specific binding of Cur-NPs-APgp to KB-V1 cells was significantly higher than that to KB-3-1 cells. Cellular uptake of Cur-NPs-APgp into KB-V1 cells was higher, as compared to KB-3-1 cells. However, the cellular uptake of Cur-NPs and Cur-NPs-IgG did not differ between the two types of cells. Besides, the cytotoxicity of Cur-NPs-APgp in KB-V1 cells was higher than those of Cur and Cur-NPs. CONCLUSION The results demonstrate that Cur-NPs-APgp targeted to P-gp on the cell surface membrane of KB-V1 cells, thus enhancing the cellular uptake and cytotoxicity of Cur.
