Leishmanicidal activity of some aliphatic diamines and amino-Alcohols
摘要:
A number of aliphatic diamines and amino-alcohols and several of their alkyl, acyl and carbamoyl derivatives, have been synthesised and evaluated in vitro on cultures of Leishmania spp. In general, diamine derivatives resulted to be more potent than their amino-alcohol or amino-ether analogues. Two diamine derivatives (8b and 9d) and one amino-alcohol (6a) showed a fair inhibition of parasite growth, at concentrations below 10 mug/mL, with potencies close to that of the reference drug, amphotericin B. Some SAR considerations have been deduced. (C) 2002 Elsevier Science Ltd. All rights reserved.
Long-Chain Aminoalcohol and Diamine Derivatives Induce Apoptosis through a Caspase-3 Dependent Pathway
摘要:
A number of long chain diamines and aminoalcohols and several of their alkyl, acyl and carbamoyl derivatives, have been synthesized and evaluated for their apoptotic activities using the Jurkat cell line. Apoptosis was measured by flow cytometry and the best results were found for the aminoalcohols displaying either a free alcohol or an amine with at least, one free hydrogen atom. The apoptotic pathway was mediated by a disruption of the mitochondria transmembrane potential and caspase-3 activation, inducing DNA fragmentation at the phase G(1)/S of the cell cycle.
