weaker than tyrosine and phenylalanine, 2.5–13 Ω−1 cm2 mol−1. The melting points and pH values of Schiffbases are compared with those of some α-aminoacids and some related Schiffbases that have no COOH group in their structures. On the bases of these data, it was concluded that carboxylated Schiffbases exist in two forms, the ionized and the free base where the later is predominant. The ionized form

AbstractThe microwave assisted, solvent free, parallel syntheses of title compounds is described in this protocol. Twelve new tetraaryl imidazoles, which are incorporated with the chemotherapeutic pharmacophores, have been synthesized by adopting one pot multicomponent reaction. Attempt has been made to investigate the mechanism behind the formation of tetraaryl imidazoles by product identification method. The synthesized compounds were analyzed by physical and analytical data. The synthesized compounds were evaluated for their antibacterial, antitubercular, and short‐term anticancer activity. Compound 13 was found to be the candidate compound to investigate further for its potential anticancer activity. J. Heterocyclic Chem., 46, 278 (2009).
