  • Tryptamine analogues as 5-ht1-like agonists
    Patent number: 5637593
    Abstract: A compound of structure (I), in which A.sup.1 is O, S(O).sub.n in which n is 0, 1 or 2, NR, CH.sub.2, or CH(OH); A.sup.2 is a bond or CH.sub.2 ; or A.sup.1 A.sup.2 is CH.dbd.CH; R is hydrogen or C.sub.1-4 alkyl; R.sup.1 is an optionally substituted 6- to 10-membered aryl or heteroaryl ring; suitably R.sup.1 is an optionally substituted 6- 10-membered aryl ring such as phenyl or naphthyl; suitably R.sup.1 is optionally substituted 6- to 10-membered heteroaryl ring, containing from 1 to 4 nitrogen atoms; R.sup.2 is hydrogen, halogen, C.sub.1-4 alkyl, CN, NO.sub.2 or CF.sub.3 ; R.sup.3 is C(R.sup.4)(R.sup.5)CH.sub.2 NR.sup.6 R.sup.7, --CH.dbd.NNHC(NH)NH.sub.2 or a; R.sup.4 and R.sup.5 are independently hydrogen or C.sub.1-4 alkyl; R.sup.6 and R.sup.7 are the same or different and are each hydrogen or C.sub.1-4 alkyl or together with the nitrogen atom to which they are attached form a ring; R.sup.8 is hydrogen, C.sub.1-4 alkyl, or C.sub.
