An expedient synthetic route for 3-aryl β-carbolin-1-ones was developed starting from ethyl acetamidocyanoacetate and chalcone derivatives. The five- and six-membered nitrogen-containing rings in the β-carbolin-1-ones were elaborated efficiently by an intramolecular ketone-nitrile annulation and an intramolecular N-arylation of amide respectively.

A novel three-step synthesis of 3-aryl β-carbolin-1-ones from non-indole starting materials has been developed. The two nitrogen atoms in β-carbolin-1-one were introduced efficiently by Michael addition of ethyl acetamidocyanoacetate to chalcone. The desired pyridone and indole rings were assembled by an intramolecular ketoneânitrile annulation mediated by aqueous HClâHOAc and a Cu(I)-catalyzed intramolecular N-arylation of the amide, respectively. The target compounds were found to possess significant activity against tumor cell proliferaton.

oxime derivatives against cisplatin-mediated celldeath in LLC-PK1 porcine kidney epithelial cells. Treatment with compounds 161-A and 161-F improved cisplatin-mediated LLC-PK1cell damage and increased cell viability by more than 80% of the control value when compared with that of cisplatin-treated cells. In addition, 161-A and 161-F reduced cisplatin-induced apoptosis. Analysis of the molecular mechanisms
