Abstract
Disclosed herein are aminomethyl derivatives each of which is of the following general formula (I): ##STR1## wherein A represents a group --C.tbd.C-- or --CH.dbd.CH--, Y represents a group ##STR2## (in which R.sub.3 being a lower alkyl or alkoxy group or a halogen atom) or ##STR3## (in which R.sub.4 being a hydrogen atom or R.sub.3), and R.sub.1 and R.sub.2 represent individually a lower alkyl group, with a proviso that Y is other than the group ##STR4## when A means the group --CH.dbd.CH--, their preparation process and platelet aggregation inhibitors containing same.
Claims4
An aminomethyl derivative of the formula:
- ##STR12## wherein A is selected from the group consisting of --C.tbd.C-- and --CH.dbd.CH--, Y is the group ##STR13## wherein R.sub.4 is a hydrogen atom, a halogen atom, a lower alkyl or alkoxy group, and R.sub.1 and R.sub.2 are, individually, a lower alkyl group.
A platelet aggregation inhibitor comprising an effective amount of an aminomethyl derivative of the formula:
- ##STR14## wherein A is selected from the group consisting of --C.tbd.C-- and --CH.dbd.CH--, Y is the group ##STR15## wherein R.sub.4 is a hydrogen atom, a halogen atom, a lower alkyl or alkoxy group, and R.sub.1 and R.sub.2 are, individually, a lower alkyl group;
- and
- a pharmaceutically acceptable carrier or excipient.
