In order to discuss the structure activity relationship (SAR) of the thio-benzodiazepine compounds which showed excellent activity against p53-MDM2 protein-protein interaction, we designed and synthesized twenty compounds with electrophilic and nucleophilic groups on the benzene ring. Among them, compounds 8i (K-i = 91 nM) and 8n (K-i = 89 nM) showed better binding activity than that of the reference drug Nutlin-3a (K-i = 121 nM). In addition, in vitro antitumor activity against Saos-2, U-2 OS, A549 and NCI-H1299 cell-lines were assayed by the MTT method. Especially, compounds 8i and 8n possessed excellent biological activity and good selectivity comparable to Nutlin-3a, which were promising candidates for further evaluation.
