In the search for potential immunomodulators methyl L-(—)-thiazolidine-4-carboxylate (2), 2-amino-2-thiazoline (12), and 2-aminothiazole (19) were transformed into derivatives of various bicyclic systems. Thus, from compound 2 derivatives of perhydrothiazolo[3,4-a]pyrazine 4 and 5, perhydrothiazolo[4,3-c]-[1,4]oxazine 7, and perhydroimidazo[1,5-c]thiazole 9a,b, from compound 12 derivatives of 2,3-dihydro-thiazolo[2
在寻找潜在的免疫调节剂时,将L -(-)-噻唑烷-4-羧酸甲酯(2),2-氨基-2-噻唑啉(12)和2-氨基噻唑(19)转化为各种双环系统的衍生物。因此,由过氢噻唑并[3,4- a ]吡嗪4和5的化合物2衍生物,全氢噻唑并[4,3- c ]-[1,4]恶嗪7和全氢咪唑并[1,5- c ]噻唑9a,b形成。由2,3-二氢噻唑并[2,3- b ]嘧啶13a,b的化合物12衍生物和咪唑并[2,1- b ]噻唑的化合物19衍生物制备21、22、24和25 。6-(对氨基磺酰基苯基)-7-氧杂氢咪唑[1,5- c发现]噻唑-5-硫酮(9a)具有免疫修复活性。
