O-Aryl, O-alkyl, O-alkenyl and O-alkynyl-macrolides of the general structural Formula I: ##STR1## have been prepared from suitable precursors by alkylation and/or arylation at C-3" and/or C-4" of the cyclohexyl ring. These macrolide immunosuppressants are useful in a mammalian host for the treatment of autoimmune diseases, infectious diseases and/or the prevention of rejection of foreign organ transplants. In addition, these macrolide immunosuppressants are useful in the topical treatment of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses. Also, these macrolides are useful in the treatment of reversible obstructive airways disease, particularly asthma; as hair revitalizing agents, especially in the treatment of male pattern alopecia or alopecia senilis; in the reversal of multidrug resistance of tumor cells; in treatment of inflammation of mucosa and blood vessels, gastric ulcers, vascular damage, ischemic bowel disease, necrotizing enterocolitis, intestinal lesions associated with thermal burns; in the treatment of cytomegalovirus infection; and in the treatment of idiopathic thrombocytopenic purpura and Basedow's disease.
通式I的O-芳基、O-烷基、O-烯基和O-炔基大环内酯,通过在环己烷环的C-3"和/或C-4"处烷基化和/或芳基化制备而成。这些大环内酯免疫抑制剂在哺乳动物宿主中用于治疗自身免疫性疾病、传染病和/或外源性器官移植排斥的预防。此外,这些大环内酯免疫抑制剂在治疗炎症和过度增生性皮肤疾病以及免疫介导疾病的皮肤表现方面具有应用价值。此外,这些大环内酯在可逆性阻塞性呼吸道疾病,尤其是哮喘的治疗中具有应用价值;作为头发复苏剂,特别是在男性型脱发或老年性脱发的治疗中;在肿瘤细胞多药耐药性的逆转中;在黏膜和血管炎症、胃溃疡、血管损伤、缺血性肠病、坏死性肠炎、与热烧伤相关的肠道损伤的治疗中;在巨细胞病毒感染的治疗中;以及在特发性血小板减少性紫癜和Basedow病的治疗中具有应用价值。
