Description: D-609, also known as D-609 free, is a phospholipase C inhibitor potentially for the treatment of pancreatic cancer. D-609, an inhibitor of PC-PLC and sphingomyelin synthase, strongly inhibited myogenic tone and had no effect on depolarization-induced contraction. D-609 appeared to act by lowering cytoplasmic Ca(2+) concentration to levels below those that activate contraction.
