  Synthesis and evaluation of some lipidic aminoalcohols and diamines as immunomodulators

  摘要：

  Lymphoproliferation inhibition and cytotoxicity of a number of lipidic aminoacids, aminoalcohols and diamines were evaluated as a preliminary screening to select potential immunomodulators. The four most potent/less toxic compounds were submitted to delayed hypersensibility (DTH) assays to define the best to be evaluated further Graft-vs-Host, NO production and other immunoevaluation (CD4(+), CD45, CD8, CD11b, I-Ek, and NK cells) assays, to establish their immunomodulation potential for being further considered as auxiliary agents for vaccination against some parasitic infections. Compounds 5d, 6d, 6f, 7a, and 9a, fairly inhibited the lymphoproliferation (71.6-79.5%, at 3.2-2.4 nM), while the antinoalcohol derivative 6f and the diamine 7a gave the most promising results in the DTH assays. Diamine derivative 8b induced nitrite production on normal macrophages, whereas compounds 6f and 7a induced nitrite production on LPS pre-stimulated macrophages. These two last compounds have been selected to follow in vivo vaccination assays. (c) 2006 Elsevier Ltd. All rights reserved.

• Leishmanicidal activity of some aliphatic diamines and amino-Alcohols

  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.

  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.

  Fifteen dihydrosphingosine analogues have been synthesized and tested in vitro against Mycobacterium tuberculosis (MTB). Two ether ( 3 and 4b) and one diamine (8b) derivatives have displayed high mycobactericidal potency, with similar MIC values of 1.25 mu g/mL, against the virulent strain H37Rv, as well as against a clinical isolate resistant to the five first-line anti-TB drugs. The three compounds, tested on other eleven cultured MTB strains with different multi-drug-resistance (MDR) patterns, retained their MIC values for most strains, or even lowered it, as in the case of compound 4b, which, assayed on strain No. 332, also resistant to all first-line anti-TB drugs, attained the MIC value of 0.78 mu g/mL.
