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 μg/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 μg/mL.

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 microg/mL, with potencies close to that of the reference drug, amphotericin B. Some SAR considerations have been deduced.

We have synthesised some lipidic diamines and aminoalcohols and examined their behaviour as inhibitors of secretory and cytosolic PLA2. Some structure-activity relationships considerations have been deduced. Compound 14 was a potent and selective inhibitor of cPLA2 and compound 4 showed a dual inhibitory profile against both types of PLA2 while no cytotoxicity at 10 μM on human neutrophils or on murine macrophage line was observed for both.
