Early in vitro evidence indicates that deacetylated sialic acids modulate multi-drug resistance in colon and lung cancers via breast cancer resistance protein. Front Oncol 2023; 13:1145333. [PMID: 37377914 PMCID: PMC10291187 DOI: 10.3389/fonc.2023.1145333] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 05/30/2023] [Indexed: 06/29/2023] Open
Abstract
Cancers utilize sugar residues to engage in multidrug resistance. The underlying mechanism of action involving glycans, specifically the glycan sialic acid (Sia) and its various functional group alterations, has not been explored. ATP-binding cassette (ABC) transporter proteins, key proteins utilized by cancers to engage in multidrug resistant (MDR) pathways, contain Sias in their extracellular domains. The core structure of Sia can contain a variety of functional groups, including O-acetylation on the C6 tail. Modulating the expression of acetylated-Sias on Breast Cancer Resistance Protein (BCRP), a significant ABC transporter implicated in MDR, in lung and colon cancer cells directly impacted the ability of cancer cells to either retain or efflux chemotherapeutics. Via CRISPR-Cas-9 gene editing, acetylation was modulated by the removal of CAS1 Domain-containing protein (CASD1) and Sialate O-Acetyl esterase (SIAE) genes. Using western blot, immunofluorescence, gene expression, and drug sensitivity analysis, we confirmed that deacetylated Sias regulated a MDR pathway in colon and lung cancer in early in vitro models. When deacetylated Sias were expressed on BCRP, colon and lung cancer cells were able to export high levels of BCRP to the cell's surface, resulting in an increased BCRP efflux activity, reduced sensitivity to the anticancer drug Mitoxantrone, and high proliferation relative to control cells. These observations correlated with increased levels of cell survival proteins, BcL-2 and PARP1. Further studies also implicated the lysosomal pathway for the observed variation in BCRP levels among the cell variants. RNASeq data analysis of clinical samples revealed higher CASD1 expression as a favorable marker of survival in lung adenocarcinoma. Collectively, our findings indicate that deacetylated Sia is utilized by colon and lung cancers to engage in MDR via overexpression and efflux action of BCRP.

Antiproliferative, molecular docking, and bioavailability studies of diarylheptanoids isolated from stem bark of Garuga pinnata Rox B. 3 Biotech 2023; 13:208. [PMID: 37229275 PMCID: PMC10203062 DOI: 10.1007/s13205-023-03581-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 04/21/2023] [Indexed: 05/27/2023] Open
Abstract
Diarylheptanoids are a major class of plant secondary metabolites characterized by 1, 7-diphenyl heptanes in a seven-member carbon frame. In the present study, diarylheptanoids (garuganins 1, 3, 4 and 5) isolated from Garuga pinnata stem bark were evaluated for cytotoxic activity against MCF-7 and HCT15 cancer cell lines. Among the tested compounds, garuganin 5 and 3 exhibited the highest cytotoxic activity against HCT15 and MCF-7 with IC50 2.9 ± 00.8 μg/mL, 3.3 ± 0.1 μg/mL and 3.2 ± 0.1 μg/mL, and 3.5 ± 0.3 μg/mL, respectively. The molecular docking of garuganin 1, 3, 4 and 5 exhibited significant affinity toward the tested EGFR 4Hjo protein. The free energy and inhibitory constant of the compounds ranged from - 7.47 to - 8.49 kcal/mol and 3.34 micromolar to 944.20 nM nanomolar, respectively. Based on the results of cytotoxic activity, garuganin 5 and 3 were further evaluated for time- and concentration-dependent intracellular accumulation studies. The time-dependent intracellular concentration of garuganin 3 and 5 after 5 h of incubation increased about 5.5- and 4.5-fold, 204.16 ± 0.02 and 145.4 ± 0.36 nmol/L mg, respectively. The concentration-dependent intracellular concentration of garuganin 3 and 5 at 200 µg/mL increased of about > 12- and ninefold, 186.22 ± 0.05 and 98.73 ± 0.02 nmol/L mg, respectively. The intracellular concentrations of garuganin 3 and 5, in the presence of verapamil, cyclosporine and MK 571, was found to be significant in the basal direction compared to the apical directions. The results indicate that, garuganin 3 and 5 exhibited significant cytotoxic activity against MCF-7 and HCT15 cancer cell lines and also exhibited high binding affinity toward EGFR protein compared to garuganin 1 and 4.

PLANTS 2022; 11:plants11141875.

Abstract
Hirsutanone (Hir) and oregonin (Ore) are diarylheptanoids isolated from the bark of Alnus japonica. In this study, we investigated the anti-melanogenic activity of Hir and Ore in B16-F1 murine melanoma and normal human epidermal melanocytes (HEMn-DP) and elucidated the mechanisms of action. In B16-F1 cells, Hir and Ore suppressed melanin synthesis induced by α-melanocyte-stimulating hormone (α-MSH) without cytotoxicity. The inhibitory effect of Hir on melanin synthesis was much stronger than that of Ore. In addition, Hir reduced melanin content in HEMn-DP cells. As tyrosinase is a key enzyme in melanin synthesis, the effect of Hir on tyrosinase activity was assessed. The results demonstrated that Hir partially decreased tyrosinase activity and intracellular tyrosinase activity. Moreover, Hir suppressed the protein expression of melanogenic enzymes, including tyrosinase, tyrosinase-related protein (TRP)-1, and TRP-2, leading to reduced melanin biosynthesis. Hir also led to the suppression of cAMP response element-binding protein (CREB) phosphorylation and microphthalmia-associated transcription factor (MITF) expression, which control the expression of melanogenic enzymes. These results suggest that Hir suppressed melanin synthesis by dual inhibition of tyrosinase activity and the CREB/MITF pathway leading to the expression of melanogenic enzymes and may be a potent cosmetic and therapeutic agent for hyperpigmentation disorders.

Abstract
Natural products, remains the most important source for the discovery of new drugs for the treatment of human diseases. This has inspired the synthetic community to design and develop mimics of natural products either to answer important questions in biology or to explore their therapeutic potentials. Glycosides present themselves abundantly in nature, right from the cell surface receptors to natural products of any origin. The O-Glycosides are hydrolytically less stable compared to C-glycosides and this feature has presented a great opportunity for drug discovery. The discovery of Dapagliflozin, an SGLT inhibitor and C-glucoside, for the treatment of diabetes is one such example. Aryl acyl-anion chemistry has been explored for the synthesis of 2-deoxy-C-aryl furanoside/pyranoside/septanosides. Besides success, the studies have provided valuable insight into the natural propensities of the architectural framework for the cascade to furan derivatives. The aryl acyl-anion chemistry has also enabled the synthesis of biologically active diaryl heptanoids. Inspired from sucesss of Dapagliflozin, new analogues have been synthesized with pyridine and isocoumarin heterocycle as the proximal ring. C-glucosides of isoliquiritigenin have been synthesized for the first time and evaluated as an efficient aldose reductase inhibitor. The synthesis and evaluation of acyl-C-β-D-glucosides and benzyl-C-β-D-glucoside as glucose-uptake promoters has revealed promise in small molecules. The concept of building blocks has been used to obtain natural oxylipins, D-xylo and L-xylo-configured alkane tetrols and novel lipophilic ketones with erythro/threo configured trihydroxy polar head-group as possible anti-mycobacterial agents.

Abstract
Inflammation involving the innate and adaptive immune systems is a normal response to infection. However, if it becomes uncontrolled, inflammation may result in autoimmune or auto inflammatory disorders, neurodegenerative diseases or cancers. The currently available anti-inflammatory drug therapy is often not successful or induces severe side effects. Thus, the search of new therapeutic options for the treatment of inflammation is highly required. Medicinal plants have been an interesting source for obtaining new active compounds. Diarylheptanoids characterized by a 1, 7-diphenylheptane structural skeleton, are a class of secondary plant metabolites that have gained increasing interest over the last few decades due to a wide variety of biological activities. This review covers 182 natural linear or macrocyclic diarylheptanoids described in the period of 1982 to 2020 with anti-inflammatory activities evaluated using quantified in vitro and/or in vivo assays. All of these data highlight the pharmacological potential of these natural compounds to act as anti-inflammatory drugs.

Abstract
Betula platyphylla bark has been evaluated for the treatment of dermatitis, inflammatory conditions, and cancer. Diarylheptanoids are the major constituents of the B. platyphylla bark and possess various pharmacological effects. Our previous study confirmed the selective antiproliferative effect of platyphylloside (BPP) isolated from B. platyphylla on colon cancer and leukemic cells using 60 different cancer cell lines from thr National Cancer Institution (NCI). In line with previous reports, this study focuses on the apoptotic pathway of BPP, a phenolic glycoside composed of two aromatic rings joined by a seven-carbon chain. Cytotoxicity assays in solid tumor and blood cancer cell models demonstrated that BPP possesses potent antiproliferative activity. The level of apoptosis increased with BPP treatment, causing cell cycle arrest at the G1 phase along with the downregulation of IκBα phosphorylation and BCL-2, as well as upregulation of cleaved caspase 3 and BAX proteins. In addition, BPP displayed potent mitochondrial depolarization effects in Jurkat cells. The combined findings revealed that the cytotoxic effects of BPP were mediated by intracellular signaling, possibly through a mechanism involving the upregulation of mitochondrial reactive oxygen species (ROS). Thus, BPP could be a potential multitarget therapeutic agent in leukemia and colon cancer.

Abstract
Background: Liquiritin (LQ) and its aglycone, liquiritigenin (LQG), are major flavonoids in licorice root (Glycyrrhiza spp.). Our preliminary screening identified LQ and LQG, which promote melanin synthesis in the melanoma cells. In this study, we investigated the molecular mechanism of melanin synthesis activated by LQ and LQG. Methods: Murine (B16-F1) and human (HMVII) melanoma cell lines were treated with LQ or LQG. After incubation, melanin contents, intracellular tyrosinase activity, and cell viability were evaluated. Protein levels were determined using Western blotting. Results: LQ and LQG activated melanin synthesis and intracellular tyrosinase activity. The induction of melanin and intracellular tyrosinase activity by LQG was higher than that by LQ. LQ and LQG induced the expression of tyrosinase, tyrosinase-related protein (TRP)-1, and TRP-2. LQ and LQG also enhanced microphthalmia-associated transcription factor (MITF) expression, and cyclic AMP-responsive element-binding protein (CREB) phosphorylation. The phosphorylation of p38 and extracellular signal-regulated kinase (ERK), but not Akt, was significantly increased by LQ or LQG. Furthermore, LQ- or LQG-mediated melanin synthesis was partially blocked by p38 inhibitor (SB203580) and protein kinase A (PKA) inhibitor (H-89); however, ERK kinase (MEK) inhibitor (U0126) and phosphatidylinositol-3-kinase (PI3K) inhibitor (LY294002) had no effect. Conclusions: The results suggest that LQ and LQG enhance melanin synthesis by upregulating the expression of melanogenic enzymes, which were activated by p38 and PKA signaling pathways, leading to MITF expression and CREB phosphorylation.

Abstract
Diarylheptanoids display an array of biological and pharmacological properties. We previously reported the synthesis of a diarylheptanoid Alpinoid c and a series of its derivatives, evaluated their cytotoxicity against various human cancer cells. We found some of these derivatives were significantly more potent than Alpinoid c in preventing the proliferation of various cancer cell lines. Among these, (S, E)-1-(3, 4 dimethoxyphenyl)-6-hydroxy-7-phenylhept-4-en-3-one (DPHP) showed most potent cytotoxicity against COLO205 cells, however, the mechanism by which DPHP prevents the growth of these colon cancer cells remains unknown. In the current study, we investigated the molecular mechanism of DPHP on colon cancer cells. DPHP inhibited the proliferation of COLO205 (IC50 7.01 ± 0.62 μM) and A549 (IC50 20.03 ± 3.11 μM) cells more specifically than normal human colon epithelial cell line NCM460 (IC50 55.6 ± 4.02 μM). In COLO205 cells, DPHP induced cell shrinkage, membrane blebbing, chromatin condensation, phosphatidylserine externalization, and an accumulation of cells at sub-G1 phase. Further analysis these cells treated with DPHP revealed a decrease in mitochondrial membrane potential, an increase in Bax/Bcl2 ratio, the release of cytochrome c, activation of caspases -9, -3/7, and cleavage of the poly-ADP-ribose polymerase. DPHP treatment resulted in inhibition of hypoxia induced VEGF downstream signaling pathway in COLO205 cells is concurrent with inhibition of angiogenesis in CAM. Based on these data we suggest that DPHP significantly induced apoptosis possibly via intrinsic mitochondrial apoptosis pathway and inhibited angiogenesis. Our study suggests DPHP could be a therapeutic agent in treating colon cancer.

Abstract
Berberine (BBR), an isoquinoline alkaloid, is a well-known bioactive compound contained in medicinal plants used in traditional and folk medicines. In this study, we investigated the subcellular localization and the apoptotic mechanisms of BBR were elucidated. First, we confirmed the incorporation of BBR into the cell visually. BBR showed antiproliferative activity and promptly localized to the nucleus from 5[Formula: see text]min to 15[Formula: see text]min after BBR treatment in HL-60 human promyelocytic leukemia cells. Next, we examined the antiproliferative activity of BBR (1) and its biosynthetically related compounds (2-7) in HL-60 cells. BBR exerted strongest antiproliferative activity among 1-7 and the results of structures and activity relation suggested that a methylenedioxyl group in ring A, an [Formula: see text]-alkyl group at C-9 position, and the frame of isoquinoline may be necessary for antiproliferative activity. Moreover, BBR showed the most potent antiproliferative activity in HL-60 cells among human cancer and normal cell lines tested. Next, we examined the effect of BBR on molecular events known as apoptosis induction. In HL-60 cells, BBR induced chromatin condensation and DNA fragmentation, and triggered the activation of PARP, caspase-3 and caspase-8 without the activation of caspase-9. BBR-induced DNA fragmentation was abolished by pretreatment with inhibitors against caspase-3 and caspase-8, but not against caspase-9. ERK and p38 were promptly phosphorylated after 15 min of BBR treatment, and this was correlated with time of localization to the nucleus of BBR. These results demonstrated that BBR translocated into nucleus immediately after treatments and induced apoptotic cell death by activation of caspase-3 and caspase-8.

Abstract
Diarylheptanoids are a class of secondary plant metabolites with a wide variety of bioactivity. Research on their phytochemistry and phytoanalysis is rapidly growing and the number of identified structures bearing the aryl-C7-aryl skeleton is at present approaching 500. Historically, the yellow pigment curcumin has been characterized as the first diarylheptanoid and the extensive research on naturally occurring analogues is still ongoing. In this review, studies dealing with the characterization of linear and cyclic derivatives are discussed from the phytoanalytical point of view. Isolation, fractionation and purification strategies from natural sources along with their chromatographic behavior and structural characteristics are discussed. The role of various techniques used for the extraction (such as Soxhlet extraction, sonication, maceration/percolation, microwave-assisted extraction, supercritical carbon dioxide extraction); isolation (liquid-liquid extraction, column chromatographic techniques, preparative thin-layer and high-performance liquid chromatography, centrifugal partition chromatography, counter-current chromatography); separation (thin-layer chromatography, high-performance liquid chromatography, gas chromatography, capillary electrophoresis) and structural characterization (UV/Vis spectroscopy, infrared spectroscopy, X-ray crystallography, mass spectrometry, nuclear magnetic resonance spectroscopy and circular dichroism spectroscopy) are critically reviewed.

Abstract
Colon cancer is one of the most common cancers. In this study, we isolated a lignan [(−)-(2R,3R)-1,4-O-diferuloylsecoisolariciresinol, DFS] from Alnus japonica (Betulaceae) and investigated its biological activity and mechanism of action on colon cancer. DFS reduced the viability of colon cancer cells and induced cell cycle arrest. DFS also suppressed β-catenin nuclear translocation and β-catenin target gene expression through a reduction in FoxM1 protein. To assess the mechanism of the action of DFS, we investigated the effect of DFS on endogenous and exogenous FoxM1 protein degradation in colon cancer cells. DFS-induced FoxM1 protein degradation was suppressed by lysosomal inhibitors, chloroquine and bafilomycin A1, but not by knock-down of proteasomal proteins. The mechanism of DFS for FoxM1 degradation is lysosomal dependent, which was not reported before. Furthermore, we found that FoxM1 degradation was partially lysosomal-dependent under normal conditions. These observations indicate that DFS from A. japonica suppresses colon cancer cell proliferation by reducing β-catenin nuclear translocation. DFS induces lysosomal-dependent FoxM1 protein degradation. This is the first report on the lysosomal degradation of FoxM1 by a small molecule. DFS may be useful in treating cancers that feature the elevated expression of FoxM1.

BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 16:473. [PMID: 27863496 PMCID: PMC5116142 DOI: 10.1186/s12906-016-1447-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/23/2016] [Accepted: 11/03/2016] [Indexed: 12/15/2022]
Abstract
BACKGROUND KIOM-CRC#BP3B (BP3B) is a novel herbal prescription that is composed of three plant extracts. Our preliminary study identified that BP3B exhibited potent anti-proliferative activity against various types of cancer cell lines in vitro. Because the in vivo anti-tumor effect of BP3B is not evaluated before clinical trial, we want to test it using patient's samples. METHODS To confirm the in vivo anti-cancer effect of BP3B, we used genetically characterized patient-derived colon tumor xenograft (PDTX) mouse model. Anti-cancer activity was evaluated with apoptosis, proliferation, angiogenesis and histological analysis. RESULTS Oral administration of BP3B significantly inhibited the tumor growth in two PDTX models. Furthermore, TUNEL assay showed that BP3B induced apoptosis of tumor tissues, which was associated with degradation of PARP and Caspase 8 and activation of Caspase 3. We also observed that BP3B inhibited cancer cell proliferation by down-regulation of Cyclin D1 and induction of p27 proteins. Inhibition of angiogenesis in BP3B-treated group was observed with immunofluorescence staining using CD31 and Tie-2 antibodies. CONCLUSION These findings indicated that BP3B has a strong growth-inhibitory activity against colon cancer in in vivo model and will be a good therapeutic candidate for treatment of refractory colon cancer.

Abstract
Background: Mammea siamensis (Miq.) T. Anders. is used as a medicinal plant in Thailand and has several traditional therapeutic properties. In a previous study, we isolated eight compounds from the flower of M. siamensis and demonstrated that kayeassamin A (KA) exhibited potent antiproliferative activity against human leukemia and stomach cancer cell lines. Objective: In this study, we investigated the effect of KA on cell viability and apoptotic mechanisms in HL-60 human leukemia cells. Materials and Methods: Cell viability was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Nuclear morphology and DNA fragmentation were observed using Hoechst 33258 staining and agarose gel electrophoresis, respectively. The sub-G1 phase of cells was analyzed by flow cytometry after the cellular DNA had been stained with propidium iodide. The protein levels of poly (ADP-ribose) polymerase (PARP) and caspases were determined by Western blotting. Results: KA exhibited a significant cytotoxic effect in a dose- and time-dependent manner, and induced chromatin condensation, DNA fragmentation, and sub-G1 phase DNA content, known as molecular events associated with the induction of apoptosis. In addition, KA strongly induced the activation of PARP and caspase-3 and -8, with weak caspase-9 activation. Furthermore, KA-induced DNA fragmentation was abolished by pretreatment with z-VAD-FMK (a broad caspase inhibitor), z-DEVD-FMK (a caspase-3 inhibitor), and z-IETD-FMK (a caspase-8 inhibitor), but not by z-LEHD-FMK (a caspase-9 inhibitor) pretreatment. Conclusion: These results indicate that KA triggers apoptotic cell death by activation of caspase-3 and -8 in HL-60 cells. SUMMARY Kayeassamin A (KA) isolated from the flower of Mammea siamensis exhibited a significant cytotoxic effect in HL-60 human leukemia cells. KA triggers apoptotic cell death by activating caspase-3/-8.
Abbreviations Used: KA: Kayeassamin A; MTT: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; PARP: Poly (ADP-ribose) polymerase; PI: Propidium iodide; CA: Corosolic acid

Abstract
Systems for artificial insemination have been established in some animals. However, due to limited availability of sperm and oocytes, more effective treatment methodologies are required. Recently, it was demonstrated that the rate of in vitro fertilization (IVF) in mice was improved by adding a water extract of licorice (Glycyrrhiza uralensis), but not glycyrrhizic acid, to the artificial insemination culture medium. In this study, we examined licorice extract for active compounds using bioassay-guided separation. The results indicated that isoliquiritigenin and formononetin were the active molecules in licorice that contributed to the improved rate of IVF.
