A method is described for inhibiting IgE production which comprises administering, in an amount effective to inhibit IgE production, a prostaglandin of the formula: ##STR1## or a pharmaceutically acceptable non-toxic salt thereof, in which R is hydrogen, C.sub.1 -C.sub.5 alkyl, C.sub.3 -C.sub.8 cycloalkyl, phenyl, or mono, di- or tri-substituted phenyl in which the substituents, are selected from the group consisting of bromo, chloro, fluoro, iodo, C.sub.1 -C.sub.5 alkyl, hydroxy, nitro, acetyl, alkoxy, carboxy, acetoxy, amino, mono- or di- alkyl amino, amido and acetamido; R.sub.1 and R.sub.2 independently are hydrogen or C.sub.1 -C.sub.5 alkyl, n.sub.3, n.sub.4, n.sub.5, n.sub.6, n.sub.7, and n.sub.8 independently are zero or one; when n's are zeros, R.sub.3 and R.sub.4 together, R.sub.4 and R.sub.5 together, R.sub.5 and R.sub.6 together, and R.sub.7 and R.sub.8 together are double bonds; when n's are ones, R.sub.3, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 independently are hydrogen, R.sub.4 is hydrogen or methyl, or R.sub.3 and R.sub.4 together, R.sub.4 and R.sub.5 together, or R.sub.5 and R.sub.6 together are methylene.
本文描述了一种抑制IgE产生的方法,包括给予一种式子为:##STR1##或其药学上可接受的非毒性盐,其剂量足以抑制IgE的产生。其中R是氢、C.sub.1-C.sub.5烷基、C.sub.3-C.sub.8环烷基、苯基或单取代、双取代或三取代苯基,其取代基选自溴、氯、氟、碘、C.sub.1-C.sub.5烷基、羟基、硝基、乙酰基、烷氧基、羧基、乙酰氧基、氨基、单取代或双取代烷基氨基、酰胺和乙酰胺;R.sub.1和R.sub.2独立地是氢或C.sub.1-C.sub.5烷基,n.sub.3、n.sub.4、n.sub.5、n.sub.6、n.sub.7和n.sub.8独立地是零或一;当n为零时,R.sub.3和R.sub.4一起,R.sub.4和R.sub.5一起,R.sub.5和R.sub.6一起以及R.sub.7和R.sub.8一起是双键;当n为一时,R.sub.3、R.sub.5、R.sub.6、R.sub.7和R.sub.8独立地是氢,R.sub.4是氢或甲基,或R.sub.3和R.sub.4一起,R.sub.4和R.sub.5一起,或R.sub.5和R.sub.6一起是亚甲基。
