A series of eighteen azomethines has been synthesized by the reaction of appropriate primary aromatic amines with aryl and/or heteroaryl carboxaldehydes. The synthesized azomethines have been evaluated for their in vitro antileishmanial, antibacterial and antifungal activities. The results revealed some antifungal activity of most of the synthesized compounds, whereas the antileishmaniasis activity results highlighted that all synthesized azomethines inhibited parasite growth and most of them showed highly potent action towards Leishmania major promastigotes. No remarkable bactericidal activities were observed.

This synthesis of imines has been carried out efficiently by the condensation of carbonyl compounds with amines in the presence of silica gel supported sodium hydrogen sulfate (NaHSO4.SiO2) as a heterogeneous catalyst under microwave irradiation in solvent-free conditions. NaHSO4.SiO2 can be recovered and re-used up to ten times by simple washing with diethyl ether after each use and activated in an oven at 120°C for 1 h, thus rendering the process more economical.
Studies on the Electronic Absorption Spectra of Some Selected Furan Derivatives. Molecular Orbital Calculations

The electronic absorption spectra of three groups of furan derivatives: 2-formyl, 2-acetylfuran, and 2-furoic acid, N-(2-furylmethylene)amines and phenylfurans were investigated.The predominant conformation as well as the polarity of the molecule could be predicted from its spectrum.The investigated molecules were proved to be " all planar" configuration which led to substantial interaction between the electronic states of the subsystems.The preferred conformations of N-(2-furylmethylene)methylamine and N-(2-furylmethylene)aniline were predicted with the aid of molecular orbital calculations.
