1,2,3,4-Tetrahydrobenzothiopyrano[4,3-c]pyrazol-3-ones and 2,3-dihydro[1]benzothiopyrano[4,3-c]pyrazol-3-ones, of respective structure I and II, ##STR1## wherein n is an integer of value from 0 to 2; R is phenyl; phenyl monosubstituted with chloro, bromo, fluoro, methyl, methoxy, nitro or trifluoromethyl; or phenyl disubstituted with chloro; and X is hydrogen or chloro; are described. These novel compounds are immunoregulators which, through suppression of the immune response in mammals, are useful in inhibiting rejection of organ transplants, as well as in the therapy of auto-immune diseases.
1,2,3,4-四氢苯并硫吡喃[4,3-c]吡唑-3-酮和2,3-二氢[1]苯并硫吡喃[4,3-c]吡唑-3-酮,具有结构I和II,其中n是取值范围为0至2的整数;R是苯基;苯基单取代物为氯、溴、氟、甲基、甲氧基、硝基或三氟甲基;或苯基双取代物为氯;X是氢或氯。这些新颖化合物是免疫调节剂,通过抑制哺乳动物的免疫反应,在抑制器官移植排斥以及治疗自身免疫疾病方面具有用途。
