New potent imidazoisoquinolinone derivatives as anti-Trypanosoma cruzi agents: Biological evaluation and structure–activity relationships
摘要:
A series of novel benzoimidazo andN-aryl-5-oxo-imidazo[1,2-b] isoquinoline-10-carbothioamides was developed. All the compounds were evaluated for their in vitro action against the epimastigote form of Trypanosoma cruzi. Four of them showed higher activity than Nifurtimox. Their unspecific cytotoxicity was evaluated using HeLa and L6 cells, being non-toxic at concentrations at least 15 and 200 times higher than that of T. cruzi IC50. To gain insight into the mechanism of action, their DNA binding properties and reactivity with glutathione were studied, and QSAR study was performed. (c) 2009 Elsevier Ltd. All rights reserved.
We have developed two green, practical, and efficient procedures, including a one-pot one, to synthesize isothiocyanates from amines and carbon disulfide via desulfurization with sodium persulfate. Water is used as the solvent. Basic conditions are necessary for good chemoselectivity for isothiocyanates. Structurally diverse linear and branched alkyl amines and aryl amines are readily converted to isothiocyanates

8.38 +/- 0.10), 31, exhibit high affinity for the histamine H(3) receptor. Antagonists 30 and 31 demonstrate significant selectivity over the other histamine, H(1) and H(2), receptor subtypes and a 100-fold selectivity in the sigma(1) binding assay. Compounds 30and 31 are the most potent, selective non-imidazole histamine H(3) receptorantagonists reported in the literature to date.
