Novel pyrrolyl hydrazones and their copper complexes have been synthesized and characterized using analytical and spectral techniques to show the tetrahedral geometry for Cu(II) complexes. Biological activities of hydrazones have been assessed to understand the role of metal ion on their biological activity and the effect of pyrrolyl hydrazones. In vitro antitubercularactivity against Mycobacterium

development, chemical induction of male sterility mediated technology based on chemical hybridizing agents (CHAs) holds a great potential. N-Acylaniline derivatives, namely, ethyl 4'-fluoro oxanilate (1) and ethyl 4'-trifluoromethyl oxanilate (2) containing halogen atoms in the para position of the aryl ring and substituted amide linkage (-CO-NH-) in the acyl side chain induced >98% spikelet sterility on three
An efficient synthesis of fully substituted 2,3-dihydropyrroles has been achieved in one step through the three-componentreaction of amines, aromatic aldehydes and α-ketoamides. This atom-economical and catalyst-free reaction is highly stereoselective and generates underexplored heterocycles in a single step. These compounds were examined in an enzymatic assay that led to the identification of potent
