Synthesis and anticancer screening of 2-indolyl 5-(1,2,3,6-tetrahydropyridyl) ketones

Several derivatives of 2-indolyl 5-(1,2,3,6-tetrahydropyridyl) ketone with various substituents on the pyridine nitrogen and with or without a benzenesulfonyl group on the indole nitrogen were synthesized and characterized by spectroscopic and analytical data. Only one showed erratic but confirmed activity in the P-388 screen. The other derivatives were inactive in the L-1210 leukemia screen.
