摘要： Disclosed are KS-501 derivatives represented by the formula (I) ##STR1## wherein X represents a hydrogen atom or COOR.sub.3, Y represents hydroxy or ##STR2## and R.sub.1, R.sub.2 and R.sub.3 are the same or different and represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, provided that when R.sub.1, R.sub.2 and R.sub.3 are simultaneously hydrogen atoms, and when R.sub.1, R.sub.2 and X are simultaneously hydrogen atoms, Y does not represent ##STR3## and a pharmaceutically acceptable acid addition salt thereof. The KS-501 derivatives have a platelet aggregation-inhibiting property, and are expected to be useful as antithrombotic agent.
