The invention is directed to a series of novel compounds of the formula ##STR1## where Y is carbonyl or sulfonyl; R.sup.7 and R.sup.8 are alkyl, or R.sup.7 and R.sup.8, together with the carbon to which they are attached, form a C.sub.3-6 carbocyclic ring; R.sup.9 and R.sup.10 are each independently selected from hydrogen, hydroxyl, oximido, methyl, carboxyl, carboxyalkyl, unsubstituted or substituted alkoxycarbonyl, alkylcarbonyloxyalkyl, cyanoalkyl, hydroxyalkyl or unsubstituted amino; R.sup.11 is hydrogen, oxo, --N(R.sup.12)--CO--R.sup.13 or --CO--N(R.sup.14)--R.sup.15 ; R.sup.12 is hydrogen or unsubstituted or substituted alkyl; R.sup.13 is alkoxyl, unsubstituted or substituted heterocyclic rings selected from ##STR2## or unsubstituted or substituted alkyl; and R.sup.14 and R.sup.15 are each independently selected from hydrogen or unsubstituted or substituted alkyl. The Y moiety cannot be bonded to the camphor ring at the 3 or 6 positions. Such compounds are oxytocin antagonists useful in the treatment of preterm labor, dysmenorrhea and for the stoppage of labor preparatory to cesarean delivery.
该发明涉及一系列新颖化合物,其化学式为##STR1##其中Y为酰基或砜基;R.sup.7和R.sup.8为烷基,或者R.sup.7和R.sup.8与它们连接的碳原子一起形成一个C.sub.3-6螺环;R.sup.9和R.sup.10分别独立地选自氢、羟基、肟基、甲基、羧基、羧基烷基、未取代或取代的烷氧羰基、烷基羰氧基烷基、氰基烷基、羟基烷基或未取代氨基;R.sup.11为氢、氧、--N(R.sup.12)--CO--R.sup.13或--CO--N(R.sup.14)--R.sup.15;R.sup.12为氢或未取代或取代的烷基;R.sup.13为烷氧基、未取代或取代的杂环环选自##STR2##或未取代或取代的烷基;R.sup.14和R.sup.15分别独立地选自氢或未取代或取代的烷基。Y基不能与藿香环在3或6位置结合。这些化合物是催产素拮抗剂,用于治疗早产、痛经以及为剖宫产前停止分娩。
