To discover new anticancer agents, two series of thiosemicarboxamide derivatives were synthesized and evaluated for their antiproliferative activity against human cancer cells in vitro. Most target compounds (especially 3f, 3g, and 3h) exhibit potent antiproliferative activity against HeLa cells. Importantly, compound 3h, bearing a 4-methylphenyl substituent at N position of thiourea moiety, has significant and broad-spectrum inhibitory activities against cancer cells (HepG2, HeLa, MDA-MB231, A875, and H460 cells) with low IC50 values (5.0 μM) and shows low toxicity to normal LO2 and MRC-5 cells. Further studies show that compound 3h exerts high inhibitory activity in cancer cells by inducing the G2/M-phase arrest of cancer cells. Collectively, this study presents compound 3h as a new entity for the development of cell cycle arrest inducers for the treatment of cancer.

In the present study, a novel series of N-((substituted)carbamothioyl)-2,4-dimethylquinoline-3-carboxamide (7a-7s) was synthesized by microwave-assisted method. Structure of these derivatives was examined by spectroscopic techniques such as 1H NMR, 13C NMR, FT-IR, and ESI-MS. Further, the novel synthesized compounds were evaluated for their in-vitro biological activities against antibacterial, antifungal, antimalarial, and antituberculosis activity as well as for in-silico study. The antimalarial results demonstrated that compounds 7c and 7q (0.02 μg/mL) have notable potency against Plasmodium falciparum compared with chloroquine (0.02 μg/mL); compounds 7l (0.10 μg/mL), 7e, 7s (0.19 μg/mL), 7b, 7p (0.15 μg/mL), 7a, 7f, and 7f (0.25 μg/mL) also exhibited good activity against P. falciparum compared with quinine (0.26 μg/mL) as standard drug. Docking was performed on PFDHFR-TS, given the effect of compounds against the P. falciparum strain was excellent in comparison with standard drug. Molecular docking suggested that compounds 7b, 7i and 7c, 7e, and 7l closely bind with the active site of protein 3JSU and 4DP3, respectively, and compared with biological activity. We have also carried out molecular dynamics simulation on the best dock compound 7e complex with PDB: 3JSU to check the stability of docked complex and their molecular interaction. The calculated ADME-Tox descriptors for the synthesized compounds validated good pharmacokinetics properties, suggesting that these compounds could be used as hit for the development of the new active agents.

Thirty new pyrazoline derivatives were synthesized by cyclization of Mannich bases with thiosemicarbazides being substituted by different cyclic and aromatic amines. The structures of the compounds were elucidated by elemental analyses, UV, IR, 1H and 13C NMR and ESI-MS spectral data. The in vitro antiamoebic activity was evaluated against Entamoeba histolytica in comparison with metronidazole used as reference substance. Out of the 30 compounds screened for antiamoebic activity, 10 (5, 6, 15, 18, 25-30) were found to be better inhibitors of E. histolytica since they showed lesser IC50 values than metronidazole. The preliminary results indicated that the presence of 3-chloro or 3-bromo substituent on the phenyl ring at position 3 of the pyrazoline ring enhanced the antiamoebic activity as compared to unsubstituted phenyl ring. The study suggests that the preliminary activity of these compounds may further be explored for the development of new targets for amoebiasis.

The cyclization of chalcone with N-4 substituted thiosemicarbazides under basic condition led to the formation of new compounds, thiocarbamoyl bis-pyrazoline derivatives. The structure of the compounds were elucidated by UV, IR, 1H NMR, 13C NMR and ESI-MS spectral data and thermogravimetric analysis, and their purities were confirmed by elemental analyses. The antiamoebic activity of these complexes was evaluated by microdilution method against HM1:IMSS strain of Entamoeba histolytica and the results were compared with the standard drug, metronidazole. Structure-activity relationship shows that the compound with aromatic substituents at the thiocarbamoyl group was more active than those with the cyclic groups. However, it was clear from the IC50 values that the compounds 15 and 20 are more active and both showed a structural resemblance having an electron withdrawing groups attached to the phenyl ring. MTT assay showed that all the compounds are non-toxic to human kidney epithelial cell line.
