New benzenesulfonamide scaffold-based cytotoxic agents: Design, synthesis, cell viability, apoptotic activity and radioactive tracing studies
摘要:
A new series of thiazolidinone (5a-g), thiazinone (9a-g) and dithiazepinone (9a-g) heterocycles bearing a benzenesulfonamide scaffold was synthesized. Cytotoxicity of these derivatives was assessed against MCF-7, HepG2, HCT-116 and A549 cancer cell lines and activity was compared to the known cytotoxic agents doxorubicin and 5-FU where the most active compounds displayed better to nearly similar IC50 values to the reference compounds. For assessing selectivity, the most active derivatives against MCF-7, 5b, 5c and 5e, were also assessed against the normal breast cell line MCF-10 A where they demonstrated high selective cytotoxicity to cancerous cells over that to normal cells. Further, the effect of the most active compounds 5b-e on MCF-7 and HepG2 cell cycle phase distribution was assessed and the tested sulfonamide derivatives were found to induce accumulation of cells in the < 2n phase. To further confirm apoptosis induction, caspase 8 and 9 levels in MCF-7 and HepG2 were evaluated before and after treatment with compounds 5b-e and were found to be significantly higher after exposure to the test agents. Since 5c was the most active, its effect on the cell cycle regulation was confirmed where it showed inhibition of the CDK2/cyclin E1. Finally, in vivo biodistribution study using radioiodinated-5c revealed a significant uptake and targeting ability into solid tumor in a xenograft mouse model.

activity on human breastcancercell line MCF-7. Human (h) CA isoforms I, II and IX were included in the study. The new sulfonamides showed excellent inhibition of all three isoforms, with KIs in the range of 0.84–702 nM against hCA I, of 0.41–288 nM against hCA II and of 5.6–29.2 against the tumor-associated hCA IX, a validated anti-tumor target, with a sulfonamide (SLC-0111) in Phase I clinical trials

their anti-proliferative activity against breast cancer MCF-7 and colorectalcancer Caco-2 cell lines. Compound 4c was found to be the most potent derivative against MCF-7 (IC50 = 3.96 ± 0.21 μM), while 4j was the most active member against Caco-2 cells (IC50 = 5.87 ± 0.37 μM). Compound 4c induced the intrinsic apoptotic mitochondrial pathway in MCF-7 cells; evidenced by the enhanced expression of the
Toward a treatment of antibacterial and antifungal infections: Design, synthesis and in vitro activity of novel arylhydrazothiazolylsulfonamides analogues and their insight of DFT, docking and molecular dynamic simulations
To find out effective newantibacterial agents, a series of novel aryl-hydrazothiazolyl-sulfonamide derivatives 3a-e were synthesized and well characterized by analytical and spectroscopic techniques. All the compounds were evaluated for their antibacterial and antifungal potential and the results showed excellent antimicrobial activity of 3d against all strains, especially B. cereus (MIC = 5.54 μM

11–13 and thiazolopyranopyrimidine 6–10, 7b, 8b, and 14 derivativesbearing a sulfonamide moiety were designed and synthesized. The molecular design was performed using molecular operating environment software to predict the binding mode of the proposed compounds on hCAII. All the newly synthesized compounds were evaluated for their in vitro anticancer activity against human liver cancer cell line in which
