Synthesis of 2-oxoquinoline-3-carboxamide of ampicillin and amoxicillin as inhibitors of penicillin binding protein 1A of pseudomonas aeruginosa.

A series of ampicillin and amoxicillin derivatives were prepared by N-acylation with N1-substituted 1, 2-dihydro-2-oxoquinoline carboxylic acids by Schotten-Baumann procedure and evaluated as inhibitors of Pseudomonas aeruginosa using molecular docking study. Most of the derivatives showed remarkableactivity against Gram positive and Gram negative bacteria in vitro.

Synthesis and antimicrobial activity of some new N-acyl substituted phenothiazines.

A series of 2-substituted N-acylphenothiazines were synthesized by using imides, N-carboxymethyl imides and the structures of these newly synthesized compounds were confirmed by spectral and elemental analyses. All new compounds were tested for their antibacterial and antifungal activities. Some compounds showed promising antibacterial and antifungal activities.
