- Vital roles of peptide/protein thioesters in protein chemistry, including chemical or semi synthesis of proteins, have encouraged studies on the development of methods for the preparation of such chemical units. Biochemical protocols using intein or sortase have proved to be useful in protein chemis

- In an effort to develop potent anti-cancer agents, we have synthesized some substituted quinoxaline derivatives. Reaction of 6-bromo-3-methylquinoxalin-2(1H)-one 1 with aromatic aldehydes furnished the styryl derivatives 2a-e. Alkylation of 1 with ethyl chloroacetate produced the N-alkyl derivatives
