The present invention provides, in its principal aspect, compounds of the general formula: ##STR1## when A is --NHCO--, --N(CH.sub.3)--CO--, --NHCH.sub.2 --, --N(CH.sub.3)--CH.sub.2 --, --CH.dbd.CH--, --COCH.sub.2 --, CH.sub.2 CH.sub.2 --, --CH(OH)CH.sub.2 -- or --C.tbd.C--; X can be H, CH.sub.3, NH.sub.2, NH(CH.sub.3),N(CH.sub.3).sub.2, OH, OCH.sub.3, SH, R.sub.2 is hydrogen or a methyl or ethyl group; R.sub.3 is hydrogen or a methyl or ethyl group; n is 0, 1, 2, 3, 4, 5 or 6; R.sub.1 is selected from the group consisting of (a) alkyl; (b) C.sub.3 to C.sub.8 cycloalkyl; (c) phenyl or substituted phenyl; (d) heteroocyclic; and (f) decahydronaphthalene or octahydroindane; and When R.sub.1 and X taken together denote a 5, 6 or 6, 6 saturated bicyclic ring structure, X can be NH, O, S, SO.sub.2, When X is constrained in a 5, 6 or 6, 6, saturated bicyclic ring structure, then for example, when X.dbd.NH, R.sub.1 and X taken together mean an octahydroindole ring structure directly attached to A.
本发明在其主要方面提供了一般式化合物:##STR1## 当A为--NHCO--,--N(CH.sub.3)--CO--,--NHCH.sub.2--,--N(CH.sub.3)--CH.sub.2--,--CH.dbd.CH--,--COCH.sub.2--,CH.sub.2CH.sub.2--,--CH(OH)CH.sub.2--或--C.tbd.C--;X可以是H,CH.sub.3,NH.sub.2,NH(CH.sub.3),N(CH.sub.3).sub.2,OH,OCH.sub.3,SH,R.sub.2为氢或甲基或乙基基团;R.sub.3为氢或甲基或乙基基团;n为0, 1, 2, 3, 4, 5或6;R.sub.1选自(a)烷基;(b)C.sub.3至C.sub.8环烷基;(c)苯基或取代苯基;(d)杂环;和(f)去氢萘或八氢萘;当R.sub.1和X一起表示5, 6或6, 6饱和的双环环结构时,X可以是NH,O,S,SO.sub.2,当X被约束在5, 6或6, 6饱和的双环环结构中时,例如,当X.dbd.NH时,R.sub.1和X一起表示直接连接到A的八氢吲哚环结构。
