✦ Synopsis
A novel series of 6-chloro-1,4,2-benzodithiazine 1,1-dioxide derivatives 2-19 with alkyl, aryl or heteroaryl substituents at position 3 have been synthesized by the reaction of 4-chloro-2-mercaptobenzenesulfonamides with aldehydes, aldehyde acetals or acid anhydrides. 6-Chloro-3-(2-hydroxyphenyl)-7-methyl-2,3-dihydro-1,4,2-benzodithiazine 1,1-dioxide ( 7) exhibited remarkable activity on the leukemia CCRF-CEM cell line (GI 50 <10 nM) and moderate activity against the other 49 human tumor cell lines derived from nine different cancer type.
