Synthesis and biological evaluation of some novel 1-indanone thiazolylhydrazone derivatives as anti-Trypanosoma cruzi agents
摘要:
A series of novel 4-arylthiazolylhydrazones (TZHs) derived from 1-indanones were synthesized in good yields (66-92%) in a simple procedure using microwave irradiation and then characterized by spectroscopy studies. The compounds were evaluated for their in vitro anti-Trypanosoma cruzi activity against the epimastigote, trypomastigote and amastigote forms of the parasite. Most TZHs displayed excellent activity, and were more potent and selective than the reference drug Benznidazole, used in the current chemotherapy. Analysis of the free sterols from parasite incubated with the compounds showed that inhibition of ergosterol biosynthesis is a possible target for the action of these new TZHs. In particular, TZH 9 emerged as a promising antichagasic compound to be evaluated in animal models. (C) 2012 Elsevier Masson SAS. All rights reserved.

In the present work, we synthesized a series of thiosemicarbazones derived from 1-indanones with good anti-Trypanosoma cruzi activity. Most of them displayed remarkable trypanosomicidal activity. All the compounds showed nonspecific cytotoxicity on human erythrocytes. The ability of the new compounds to inhibit cruzipain, the major cysteine protease of T. cruzi, was also explored. Thiosemicarbazones 12 and 24 inhibited this enzyme at the dose assayed. This interaction was also studied in terms of molecular docking. (C) 2011 Elsevier Ltd. All rights reserved.
