For pure FCZ, differential scanning calorimetry revealed melting point at 137 °C, followed by two further endothermic transitions at 294 °C and 498.44 °C representing the volatilization and subsequent degradation of FCZ, respectively. The absence of endothermic FCZ melting peak at around 137 °C indicates that the complexes represent different compounds. All complexes exhibit endothermic transitions at around 240-300 °C, representing melting and removal of ligand moiety, followed by another endothermic transition at around 498-499 °C, representing the ligand decomposition.Synthesis of a natural proline-rich cyclopolypeptide - rolloamide A was carried out by coupling of tri- and tetrapeptide units Boc-Phe-Pro-Val-OMe and Boc-Pro-Leu-Pro-Ile-OMe after proper deprotection at carboxyl and amino terminals using carbodiimide chemistry in alkaline environment followed by cyclization of linear heptapeptide segment in the presence of base. The structure of synthesized peptide was confirmed by spectral techniques including FTIR, 1H NMR, 13C NMR, MS analyses. Newly synthesized peptide was subjected to biological screening against pathogenic microbes and earthworms. Cyclopeptide 8 possessed promising activity against pathogenic fungi Candida albicans (ZOI 24 mm, MIC 6 μg/mL) and Gram-negative bacteria Pseudomonas aeruginosa (ZOI 27 mm, MIC 6 μg/mL) and Klebsiella pneumoniae (ZOI 23 mm, MIC 12.5 μg/mL), in comparison to reference drugs - griseofulvin (ZOI 20 mm, MIC 6 μg/mL) and ciprofloxacin (ZOI 25 mm, MIC 6 μg/mL/ZOI 20 mm, MIC 12.5 μg/mL). Also, newly synthesized heptacyclopeptide exhibited potent anthelmintic activity against earthworms Megascoplex konkanensis,Pontoscotex corethruses, and Eudrilus species (MPT/MDT ratio - 8.22-16.02/10.06-17.59 min), in comparison to standard drugs - mebendazole (MPT/MDT ratio - 10.52-18.02/12.57-19.49 min) and piperazine citrate (MPT/MDT ratio - 12.38-19.17/13.44-22.17 min).An unbounded number of events exist beneath the intricacy of each particular hematologic malignancy, prompting the tumor cells into an unrestrained proliferation and invasion. Aberrant expression of cyclin-dependent kinases (CDKs) is one of these events which disrupts the regulation of cell cycle and subsequently, results in cancer progression. In this study, we surveyed the repressive impact of multi-CDK inhibitor AT7519 on a panel of leukemia-derived cell lines. Our data underlined that AT7519 abated the survival of all tested cells; however, in an overview, the response rate of leukemic cells to the inhibitor was varied irrespective of p53 status. Notably, the less sensitivity of leukemia cells to AT7519 was found to be mediated partly by the compensatory activation of c-Myc oncogene which was confirmed by the induction of a superior cytotoxicity upon its suppression in less sensitive cell. The blockage of cell cycle, as announced by induction of sub-G1 arrest as well as reduced S phase, resulted in a significant decrease in survival of acute promyelocytic leukemia (APL)-derived NB4 cells, as the most sensitive cell line, either as monotherapy or in combination with arsenic trioxide. selleck chemical Anti-leukemic effects of the inhibitor were further verified by apoptosis analysis, where we discovered that AT7519 induced apoptosis via alteration of pro- and anti-apoptotic genes in NB4. All in all, this study proposed that AT7519 is a rewarding agent opposed to APL; however, additional examinations should be performed to determine the advantages of this inhibitor in clinical setting.The complex [(PhCH2NC)AuCl], 1, was prepared by the reaction of [(Me2S)AuCl], A, with an equimolar amount of benzyl isocyanide (PhCH2NC) ligand. Through a salt metathesis reaction, the chloride ligand in 1 was replaced by potassium benzothiazole-2-thiolate (Kbt) and potassium benzoimidazole-2-thiolate (Kbi) to afford complexes (PhCH2NC)Au(κ1-S-bt)], 2a and (PhCH2NC)Au(κ1-S-bi)], 2b, respectively, which were characterized by NMR spectroscopy. The cytotoxic activities of 2a and 2b were evaluated against three human cancer cell lines, including A549 (lung), SKOV3 (ovary), and MCF-7 (breast). Our results indicated that 2a exhibited comparable cytotoxicity on investigated cell lines with cisplatin. It showed a good anti-proliferative activity with IC50 of 19.46, 11.76 and 13.27 μM against A549, SKOV3 and MCF-7 cell lines, respectively. The effects of these complexes on the proliferation of the non-tumorigenic epithelial breast cell line (MCF-10A) showed their good selectivity between the tumorigenic and non-tumorigenic cell lines. Molecular docking simulation studies were also conducted to determine the specific binding site and binding mode of the synthesized gold complexes to DNA and thioredoxinreductase (TrxR) as their proposed targets.Naringenin is a natural compound with potential anti-cancer effects against several cancer types. Also, its precise molecular mechanisms regarding tumor growth suppression has not been completely elucidated. In the current study the apoptosis-inducing and anti-proliferative effects of Naringenin together with cyclophosphamide were studied in breast cancer cells and the participation of JAK2/STAT3 pathway was investigated. In this regard, MDA-MB-231 breast cancer cells were cultured and hence, treated with different concentrations of Naringenin. Apoptosis was measured via flowcytometric analysis of annexin V binding and cell viability was assessed via MTT assay. Protein and gene expression were investigated via Western blotting and real-time PCR, respectively. The function of caspase enzymes were also assessed. The results exhibited that Naringenin triggered apoptosis and markedly decreased cell viability. Furthermore its coadministration with cyclophosphamide improved its anti-tumor properties. Moreover, Naringenin up-regulated the expression of BAX while decreased the expression of Bcl-2. Caspases 3 and 9 were activated by Naringenin, an influence, which was augmented via cyclophosphamide. Docking studies revealed an interaction between Naringenin and STAT3 that was confirmed via attenuation of STAT3 phosphorylation subsequent to treating the cells with Naringenin. Furthermore, Naringenin exhibited the capacity to suppress the function of IL-6 in modulating apoptosis-associated genes expression. Overall, these results indicated that a Naringenin- cyclophosphamide combination impairs proliferation signaling and induces apoptosis to a greater extent than either compound alone and can serve as a potent chemotherapeutic regimen for breast cancer treatment.
