Parasitic diseases still represent serious public health problems, since the high and steady emergence of resistant strains is evident. Because parasitic infections are distributed predominantly in developing countries, less toxic, more efficient, safer and more accessible drugs have become desirable in the treatment of the infected population. This is the case of leishmaniasis, an infectious disease caused by a protozoan of the genus Leishmania sp., responsible for triggering pathological processes from the simplest to the most severe forms leading to high rates of morbidity and mortality throughout the world. In the search for new leishmanicidal drugs, the thiosemicarbazones and the indole fragments have been identified as promising structures for leishmanicidal activity. The present study proposes the synthesis and structural characterization of new indole-thiosemicarbazone derivatives (2a-j), in addition to performing in vitro evaluations through cytotoxicity assays using macrophages (J774) activity against forms of Leishmania infantum and Leishmania amazonensis promastigote as well as ultrastructural analyzes in promastigotes of L. infantum. Results show that the indole-thiosemicarbazone derivatives were obtained with yield values varying from 32.09 to 94.64%. In the evaluation of cytotoxicity, the indole-thiosemicarbazone compounds presented CC50 values between 53.23 and 357.97 μM. Concerning the evaluation against L. amazonensis promastigote forms, IC50 values ranged between 12.31 and > 481.52 μM, while the activity against L. infantum promastigotes obtained IC50 values between 4.36 and 23.35 μM. The compounds 2d and 2i tested against L. infantum were the most promising in the series, as they showed the lowest IC50 values: 5.60 and 4.36 respectively. The parasites treated with the compounds 2d and 2i showed several structural alterations, such as shrinkage of the cell body, shortening and loss of the flagellum, intense mitochondrial swelling and vacuolization of the cytoplasm leading the parasite to cellular unviability. Therefore, the indole-thiosemicarbazone compounds are promising because they yield considerable synthesis, have low cytotoxicity to mammalian cells and act as leishmanicidal agents.

Twelve 2-(quinolin-4-ylmethylene) hydrazinecarbothioamide derivatives were synthetized and their biological properties were investigated, among which, the ability to interact with DNA and BSA through UV–Vis absorption, fluorescence, Circular Dichroism, molecular docking and relative viscosity, antiproliferative activity against MCF-7 and T-47D mammary tumor cells and RAW-264.7 macrophages and inhibitory capacity of the enzyme topoisomerase IIα. In the binding study with DNA and BSA, all the compounds displayed affinity for interaction with both biomolecules, especially JF-92 (p-ethyl-substituted), with binding constant of 1.62 × 106 and 1.43 × 105, respectively, and DNA binding mode by intercalation. The IC50 values were obtained between 0.81 and 1.48 μM and topoisomerase inhibition results in 10 μM. Thus, we conclude that the reduction of the acridine to quinoline ring did not disrupt the antitumor action and that substitution patterns are important for biomolecule interaction affinity as they demonstrate the potential of these compounds for anticancer therapy.

A number of thiosemicarbazones of 2-acetyl-imidazo[4,5-b]pyridine were prepared in order to investigate their in vitro antineoplastic activities. Three compounds: (i) 2-acetylimidazo[4,5-b]pyridin-4-tert-butyl-3-thiosemicarbazone [(A7), NSC674098], (ii) 2-acetylimidazo[4,5-e]pyridin-4-tert-butyl-3- thiosemicarbazone [(A9), NSC674099], (iii) 2-acetylimidazo[4,5-i] pyridin-4-cyclohexyl-3-thiosemicarbozone [(A11), NSC674101] showed remarkable activity against some of the cell lines tested. The Biological Evaluation Committee of N.C.I, determined that further secondary testing should be carried out (these compounds were tested against prostate cancer).

Increased bacterial resistance to antibiotics is a major threat to human health, and it is particularly important to develop novel antibiotic drugs. Here, we designed a series of Schiff base thiosemicarbazone derivatives containing an adamantane moiety, and carried out the structural characterization of the compounds and in vitro antibacterial activity tests. Compound 7e was as effective as the commonly used antibiotic ampicillin against the Gram-negative bacterium Escherichia coli, and compound 7g had a good inhibitory effect against Gram-positive Bacillus subtilis. These findings provide data for the development of better thiosemicarbazone antibacterial agents.

The superbug infection caused by New Delhi metallo-β-lactamase (NDM-1) has become an emerging public health threat. Inhibition of NDM-1 has proven challenging due to its shuttling between pathogenic bacteria. A potent scaffold, diaryl-substituted thiosemicarbazone, was constructed and assayed with metallo-β-lactamases (MβLs). The obtained twenty-six molecules specifically inhibited NDM-1 with IC50 0.038–34.7 μM range (except 1e, 2e, and 3d), and 1c is the most potent inhibitor (IC50 = 0.038 μM). The structure-activity relationship of synthetic thiosemicarbazones revealed that the diaryl-substitutes, specifically 2-pyridine and 2-hydroxylbenzene improved inhibitory activities of the inhibitors. The thiosemicarbazones exhibited synergistic antimycobacterial actions against E. coli-NDM-1, resulted a 2–512-fold reduction in MIC of meropenem, while 1c restored 16–256-, 16-, and 2-fold activity of the antibiotic on clinical isolates ECs, K. pneumonia and P. aeruginosa harboring NDM-1, respectively. Also, mice experiments showed that 1c had a synergistic antibacterial ability with meropenem, reduced the bacterial load clinical isolate EC08 in the spleen and liver. This work provided a highly promising scaffold for the development of NDM-1 inhibitors.
