Synthesis, characterization and antimicrobial studies on Cobalt (II), Nickel (II), Copper (II) and Zinc (II) complexes o

Biologically important Schiff bases L1 8-nitro-2-{[(5'-methyl-3'-isoxazolyl) imino] methyl} naphtha [NMIIMN], L2 N-[5'-methyl-3'-isoxazolyl]-N-[(E)-1-(-2 Thiophene)] methylidine] amine [MITMA] have been synthesized. Metal Chelates of NMIIMN and MITMA with Co (II), Ni (II), Cu (II) and Zn (II) metals have been synthesized and the structures of these chelates have been elucidated by elemental analysis, 1H _NMR, Mass, IR electronic spectral data and magneticmoments.

Synthesis, anticonvulsant activity & spectral characterization of some novel thiazolidinone derivatives

Synthesis, anticonvulsant activity & spectral characterization of some novel thiazolidinone derivatives

A series of substituted 5-ethylidene-2-(phenylimino) thiazolidin-4-ones were prepared and evaluate for their potential anticonvulsant activity by determining their ability to provide protection against convulsions induced by electroconvulsometer. The synthetic scheme involves phenylthiourea (I) as a starting material. Phenylthiourea on reaction with ethylchloroacetate in presence of ethanol (95%) and fused sodium acetate gives 2-(phenylimino) thiazolidin-4-one (II), 2-(phenylimino) thiazolidin-4-one on further reaction with substituted benzaldehyde gives substituted 5-ethylidene-2-(phenylimino) thiazolidin-4-one (III-VII). Synthesized compounds were authenticated on the basis of elemental analysis, IR and 1H NMR and Mass spectral analysis.
