  • Patent number: 4217357
    Abstract: A series of unsubstituted and substituted 3-(imidazol-1-ylalkyl)indole compounds has been prepared by reacting the appropriately substituted 3-methylindole starting material with imidazole per se, followed by further reaction with a proper acylating or alkylating agent of choice, if so desired. The resulting indole derivatives are useful in therapy for the treatment at ischaemic heart disease, migraine, transient ischaemic attack and stroke. Typical members include such preferred compounds as 3-(imidazol-1-ylmethyl)-1-methylindole and 3-(imidazol-1-ylmethyl)-2-isopropylindole, respectively.
