Synthesis and antitumor activity of anthracene-9-carbaldehyde amino-s-triazole Schiff-bases with side-chain of S-acetic acid

To find out a novel lead compound from heterocyclic amine Schiff bases for developing new antitumor agents, each of (4-amino-5-substituted-s-triazol-3-ylthio)-acetic acids 2a-j was condensed with anthracene-9-carbaldehyde to obtain Schiff-bases of ［4-(anthracen-9-yl methylene) amino］-5-substituted-s-triazol-3-ylsulfanyl］-acetic acids 3a-j. The structures of new compounds synthesized were characterized by elemental analysis and spectral data, and in vitro antitumor activity was also evaluated against CHO, HL60 and L1210 cell lines by MTT assay.
