Design, synthesis, structure elucidation and in vitro antiviral and antimicrobial evaluation

In this study, we described the synthesis of the derivatives of thiosemicarbazide, dicarboximide, 1,2,4-triazole-5-thione and 4-oxo-1,3-thiazolidine. Two different dicarboxylic acid anhydrides reacted with 4-substituted-3-thiosemicarbazide, and derivatives of thiosemicarbazide and dicarboximide were obtained. Next, cyclization reaction of dicarboximide derivatives in alkaline media was used to prepare 1,2,4-triazole-5-thione. The 4-oxo-1,3-thiazolidine was synthesized by the reaction of dicarboximide with ethyl bromoacetate. All obtained derivatives were analysed by H-1 and C-13 NMR spectra, and for one compound, the X-ray crystallography was done. Antimicrobial, antiviral and in vitro evaluations of cytotoxicity were examined. According to the preliminary antiviral screening, compounds 3 and 4 presented the antiviral activity against HSV-1 and CVB3. Additionally, compound 3 shows selective in vitro toxic effect against human epithelial cells FaDu, without affecting normal animal cell line (Vero).

The present study assessed the biological potential of fourteen 1,3-thiazolidin-4-ones evaluating the antiglioma effect through decreasing of cell viability of glioblastoma multiform cells. The new compounds were efficient synthesized through multicomponent or multicomponent one-pot procedures in moderate to good yields (22-86%) from two arenealdehydes (4-(methylthio)benzaldehyde and 4(methylsulfonyl)benzaldehyde), seven amines (aromatic and aliphatic) and mercaptoacetic acid. The compounds were identified and characterized by GC/MS and NMR, five of them by HRMS. Six thiazoli-dinones showed significant effect of decreasing cell viability compared to standard drug TMZ at 100 mu M in 72 h in C6 cell line by MTT assay. The compounds 5b, 5e, 5g and 6e showed the best results in the screening at 100 AM and were analyzed at different concentrations (5, 25, 50, 100 and 250 mu M). Compounds 5b and 5e showed statistical difference at 5 mu M, 6e at 25 mu M and 5g at 50 mu M in 72 h of treatment. The cytotoxicity study in primary astrocytes cells was evaluated and none of fourteen compounds showed toxicity at 100 mu M, eight of them were not cytotoxic at 250 mu M, both in 72 h. In addition, the propidium iodide assay demonstrated that the compounds might induce cell death by necrosis. In conclusion, this work reports at least four compounds (5b, 5e, 5g and 6e) with potential anti-tumor effect against glioblastoma multiform cell presenting activity at low concentrations and safe profile of cytotoxicity.

Synthesis of novel N-substitutedphenyl-6-oxo-3-phenylpyridazine derivatives as cyclooxygenase-2 inhibitors

Some novel non-ulcerogenic N-substitutedphenyl-6-oxo-3-phenylpyridazines as COX-2 inhibitors have been developed (Supplementary material Appendix1). The novel aldehyde3was prepared by reacting 6-phenylpyridazin-3(2H)-one with 4-fluorobenzaldehyde. The aldehyde3was reacted with different hydrazines and thiazolidin-4-ones to obtain the novel N-substitutedphenyl-6-oxo-3-phenylpyridazine derivatives. These were assessed for their anti-inflammatory potential and gastric ulcerogenic effects. The molecular docking investigations were also undertaken. The spectroscopic data were coherent with the allocated structures of the compounds. The compounds4a(IC50= 17.45 nm;p< .05),4b(IC50= 17.40 nm;p <.05),5a(IC50= 16.76 nm;p< .05), and10(IC50= 17.15 nm;p< .05) displayed better COX-2 inhibitory activity than celecoxib (IC50= 17.79 nm;p< .05). These findings were consistent with the molecular docking investigations of4a,4b,5a, and10. Thein vivoanti-inflammatory profile of4a,4b,5a, and10was also superior to celecoxib and indomethacin. The compounds4b,5a, and10revealed no gastric ulcerogenic effects, wherein the compound4aproduced almost negligible gastric ulcerogenic effects than celecoxib and indomethacin. The compounds4a,4b,5a, and10have been postulated as promising non-ulcerogenic COX-2 inhibitors. Interested yet?
