Abstract
Background:
A Lewis acid promoted efficient and facile procedure for one-pot synthesis
of a novel series of fluoroquinolone clubbed with thiadiazoles motifs under microwave irradiation is
described here. This technique has more advantages such as high yield, a clean procedure, low reaction
time, simple work-up and use of Lewis acid catalyst.
Objective:
Our aim is to generate a biologically active 1,3,4- thiadiazole ring system by using a onepot
synthesis method and microwave-assisted heating. High yield and low reaction time were the
main purposes to synthesize bioactive fluoroquinolone clubbed 1,3,4- thiadiazole moiety.
Methods:
Fluoroquinolone Clubbed 1,3,4-Thiadiazole Motifs was prepared by Lewis acid promoted,
one-pot synthesis, under microwave irradiation. All the synthesized molecules were determined by
IR, 1H NMR, 13C NMR, and Mass spectra. The antimicrobial activity of synthesized compounds was
examined against two Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), two
Gram-positive bacteria (Staphylococcus aureus, Streptococcus pyogenes), and three fungi (Candida
albicans, Aspergillus niger, Aspergillus clavatus) using the MIC (Minimal Inhibitory Concentration)
method and antitubercular activity H37Rv using L. J. Slope Method.
Results:
Lewis acid promoted, one-pot synthesis of Fluoroquinolone clubbed 1,3,4-Thiadiazole motifs
under microwave irradiation is an extremely beneficial method because of its low reaction time
and good yield. Some of these novel derivatives showed moderate to good in vitro antibacterial, antifungal,
and antitubercular activity.
Conclusion:
One-pot synthesis of 1,3,4-Thiadiazole by using Lewis acid catalyst gives a good result
for saving time and also getting more production of novel heterocyclic compounds with good antimicrobial
properties via microwave heating method.

Abstract
CA916798 has been identified as a novel multidrug resistance gene in lung cancer cells. However, the expression patterns of CA916798 in tumor tissues prior and subsequent to chemotherapy remain unclear. In the present study, CA916798 expression levels in tumor tissues prior and subsequent to chemotherapy were detected by reverse transcription-quantitative polymerase chain reaction and immunohistochemistry analysis. The prognostic significance of CA916798 expression in tumor tissues was explored by Kaplan-Meier survival analysis and Cox proportional hazards regression analysis. The messenger RNA (mRNA) and protein expression levels of CA916798 in tumor tissues were downregulated post-chemotherapy in chemotherapy-sensitive patients with lung cancer, but not in chemotherapy-resistant patients. Downregulation of CA916798 mRNA and protein expression post-chemotherapy was significantly associated with improved progression-free survival time. The findings from the present study suggest that platinum-based chemotherapy may induce the expression of CA916798, and CA916798 may be a promising biomarker to predict chemotherapy resistance and improve therapies for patients with lung cancer.

Abstract
A leading cause of cancer chemotherapy failure is chemoresistance, which often involves multiple mechanisms. Chinese medicines (CM) usually contain multiple components which could potentially target many mechanisms simultaneously and may offer an advantage over single compounds that target one mechanism at a time. The purpose of this study was to investigate the chemosensitizing effect (CE) of a specific CM, Tripterygium wilfordii (TW), on prostate cancer cells resistant to docetaxel (Dtx) and identify the potential mechanisms. The CE of TW (in combination with Dtx) was evaluated in two Dtx resistant prostate cancer cell lines (PC3-TxR and DU145-TxR) and the efficacy of the combination for resistant PC3-TxR tumor was investigated using a xenograft mouse model. For mechanistic study, the inhibitory effect of TW on P-glycoprotein activity was assessed. In addition, novel gene targets of TW were identified using DNA microarray and quantitative PCR. Results showed that TW induced a CE of 8 and >38 folds in PC3-TxR and DU145-TxR cells, respectively with Dtx IC50 reversed back to that of the sensitive parent cells. An optimum dose of TW+Dtx significantly retarded tumor growth in mice compared to TW or Dtx alone. TW inhibited P-glycoprotein activity and induced a significant gene expression changes in genes related to angiogenesis, cell cycle regulation and differentiation. Our in vitro and in vivo studies demonstrate that TW in combination with Dtx was able to overcome the chemoresistance and suppress resistant prostate tumor growth via multi-mechanisms.

Abstract
Multidrug resistance driven by ABC membrane transporters is one of the major reasons for treatment failure in human malignancy. Some limited evidence has previously been reported on the cell cycle dependence of ABC transporter expression. However, it has never been demonstrated that the functional activity of these transporters correlates with the cell cycle position. Here, we studied the rate of intrinsic ABC transport in different phases of the cell cycle in cultured MCF-7 breast cancer cells. The rate was characterized in terms of the efflux kinetics from cells loaded with an ABC transporter substrate. As averaging the kinetics over a cell population could lead to errors, we studied kinetics of ABC transport at the single-cell level. We found that the rate of ABC transport in MCF-7 cells could be described by Michaelis-Menten kinetics with two classical parameters, V(max) and K(M). Each of these parameters showed similar unimodal distributions with different positions of maxima for cell subpopulations in the 2c and 4c states. Compared to the 2c cells, the 4c cells exhibited greater V(max) values, indicating a higher activity of transport. They also exhibited a greater V(max)/K(M) ratio, indicating a higher efficiency of transport. Our findings suggest that cell cycle-related modulation of MDR may need to be taken into account when designing chemotherapy regimens which include cytostatic agents.

Abstract
Multidrug resistance (MDR) is a major obstacle to the effective treatment of cancer. Cellular overproduction of P-glycoprotein (P-gp), which acts as an efflux pump for various anticancer drugs (e.g. anthracyclines, Vinca alkaloids, taxanes, epipodophyllotoxins, and some of the newer antitumor drugs) is one of the more relevant mechanisms underlying MDR. P-gp belongs to the superfamily of ATP-binding cassette transporters and is encoded by the ABCB1 gene. Its overexpression in cancer cells has become a therapeutic target for circumventing MDR. As an alternative to the classical pharmacological strategy of the coadministration of pump inhibitors and cytotoxic substrates of P-gp and to other approaches applied in experimental tumor models (e.g. P-gp-targeting antibodies, ABCB1 gene silencing strategies, and transcriptional modulators) and in the clinical setting (e.g. incapsulation of P-gp substrate anticancer drugs into liposomes or nanoparticles), a more intriguing strategy for circumventing MDR is represented by the development of new anticancer drugs which are not substrates of P-gp (e.g. epothilones, second- and third-generation taxanes and other microtubule modulators, topoisomerase inhibitors). Some of these drugs have already been tested in clinical trials and, in most of cases, show relevant activity in patients previously treated with anticancer agents which are substrates of P-gp. Of these drugs, ixabepilone, an epothilone, was approved in the United States for the treatment of breast cancer patients pretreated with an anthracycline and a taxane. Another innovative approach is the use of molecules whose activity takes advantage of the overexpression of P-gp. The possibility of overcoming MDR using the latter two approaches is reviewed herein.

Syl611, a novel semisynthetic taxane derivative, reverses multidrug resistance by p-glycoprotein inhibition and facilitating inward transmembrane action. Cancer Chemother Pharmacol 2010; 66:851-9.

Abstract
PURPOSE To investigate the reversal mechanisms of a novel semisynthetic taxane derivative, Syl611. Syl611 is a structurally modified compound from Sinenxan A, and the chemical structure is entirely new. It was found to significantly increase paclitaxel-induced cytotoxicity in drug-resistant cells, while presenting a low level of cytotoxicity. METHODS The in vitro cytotoxic and MDR-reversing activities of the Syl611 were determined by MTT assays. The cytotoxicity enhancement of paclitaxel was performed using the acridine orange/ethidium bromide double staining. Rhodamine 123 accumulation and retention assay in KB/V cells, Caco-2 monolayer model were used to find mechanism of action. RESULTS The cytotoxicity of Syl611 was wondrously lower in all tested cell lines than that of paclitaxel. Cytotoxicity enhancement from Syl611 was dramatically higher than that of verapamil of the same concentration (10 muM): the reversal fold index for A549/Paclitaxel, KB/V, and Bel7402/5-FU were 45.95, 73.56, and 107.13 (Syl611) and 11.36, 23.92, and 70.42 (verapamil). AO/EB double staining assay equally showed that Syl611 could enhance the cytotoxicity induced by paclitaxel. Furthermore, Syl611 could also increase the intracellular accumulation of Rhodamine 123 in KB/V cells without affecting P-gp's expression, and this accumulation was reversible. In bidirectional permeability assay, Syl611 increased the permeability of paclitaxel but decreased the net secretory of paclitaxel. CONCLUSIONS Syl611 is an effective and potential agent in reversing multidrug resistance (MDR) by multiple actions, which attributed to p-glycoprotein inhibition and drug permeability enhancement.

Abstract
When cancer cells develop resistance to chemotherapeutics, it is frequently conferred by the ATP-dependent efflux pump P-glycoprotein (MDR1, P-gp, ABCB1). P-gp can efflux a wide range of cancer drugs; its expression confers cross-resistance, termed "multidrug resistance" (MDR), to a wide range of drugs. Strategies to overcome this resistance have been actively sought for more than 30 years, yet clinical solutions do not exist. A less understood aspect of MDR is the hypersensitivity of resistant cancer cells to other drugs, a phenomenon known as "collateral sensitivity" (CS). This review highlights the extent of this effect for the first time, and discusses hypotheses (e.g. generation of reactive oxygen species) to account for the underlying generality of this phenomenon, and proposes exploitation of CS as a strategy to improve response to chemotherapy.

Abstract
The interactions of three heavy metal-containing compounds, cisplatin (CDDP), arsenic trioxide (As(2)O(3)), and mercury dichloride (HgCl(2)), with the multidrug resistance transporters MRP1 and MRP2 and the involvement of glutathione (GSH)-related processes herein were investigated. In Madin-Darby canine kidney cells stably expressing MRP1 or MRP2, viability, GSH content, calcein efflux and polarized GSH efflux were measured as a function of exposure to CDDP, As(2)O(3) and HgCl(2). In isolated Sf9-MRP1 and Sf9-MRP2 membrane vesicles, the interaction with MRP-associated ATPase activity was measured. In the latter model system adduct formation with GSH is not an issue. The data show that (1) CDDP interacts with both MRP1 and MRP2, and GSH appears to play no major role in this process, (2) As(2)O(3) interacts with MRP1 and MRP2 in which process GSH seems to be essential, and (3) HgCl(2) interacts with MRP1 and MRP2, either alone and/or as a metal-GSH complex.

Abstract
Promising anti-breast cancer agents derived from substituted quinolines were discovered. The quinolines were readily synthesized in a large scale from a sequence of reactions starting from 4-acetamidoanisole. The Michael addition product was isolated as the reaction intermediate in the ring closing reaction of 4-amino-5-nitro-2-(3-trifluoromethylphenyloxy)anisole with methyl vinyl ketone leading to 6-methoxy-4-methyl-8-nitro-5-(3-trifluoromethylphenyloxy)quinoline (14). The amino function of 8-amino-6-methoxy-4-methyl-5-(3-trifluoromethylphenyloxy)quinoline, prepared from 14, was connected to various side chains via alkylation with N-(3-iodopropyl)phthalimide, Michael addition with acrylonitrile, and reductive amination with various heterocycle carboxaldehydes, such as imidazole-4-carboxaldehyde, thiophene-2-carboxaldehyde, and 2-furaldehyde. Effects of the substituted quinolines on cell viability of T47D breast cancer cells using trypan blue exclusion assay were examined. The results showed that the IC(50) value of 6-methoxy-8-[(2-furanylmethyl)amino]-4-methyl-5-(3-trifluoromethylphenyloxy)quinoline is 16+/-3nM, the lowest IC(50) out of all the quinolines tested. IC(50) values of three other quinolines are in the nanomolar range, a desirable range for pharmacological testing.

Abstract
This review summarizes the recent knowledge obtained on the molecular mechanisms involved in the intrinsic and acquired resistance of cancer cells to current cancer therapies. We describe the cascades that are often altered in cancer cells during cancer progression that may contribute in a crucial manner to drug resistance and disease relapse. The emphasis is on the implication of ATP-binding cassette (ABC) multidrug efflux transporters in drug disposition and antiapoptotic factors, including epidermal growth factor receptor cascades and deregulated enzymes in ceramide metabolic pathways. The altered expression and activity of these signaling elements may have a critical role in the resistance of cancer cells to cytotoxic effects induced by diverse chemotherapeutic drugs and cancer recurrence. Of therapeutic interest, new strategies for reversing the multidrug resistance and developing more effective clinical treatments against the highly aggressive, metastatic, and recurrent cancers, based on the molecular targeting of the cancer progenitor cells and their further differentiated progeny, are also described.
