Lipase-catalyzed preparation of optically active 1′-acetoxychavicol acetates and their structure–activity relationships in apoptotic activity against human leukemia HL …
Structure–activity relationships of 1′-acetoxychavicol acetate (ACA) for apoptotic activity against human leukemia HL-60 cells were investigated using optically active ACA and various racemic ACA analogues. Natural-type (or with different acyl group) ACA showed a high apoptotic activity, but the ortho or meta isomers, 4-deacetoxy analogue, and the 2′– 3′ dehydrogenated derivative had no effect, or a weak activity. Optically active (R)-and (S ...
