Isolated immunomodulatory (e.g. immunostimulatory) polyhydroxlated pyrrolizidine compounds having the formula
are disclosed. In these compounds R is selected from hydrogen, straight or branched, unsubstituted or substituted, saturated or unsaturated acyl, alkyl (e.g. cycloalkyl), alkenyl, alkynyl and aryl groups. The compounds are useful in therapy and prophylaxis, including increasing the Th1:Th2 response ratio, hemorestoration, alleviation of immunosuppression, cytokine stimulation, treatment of proliferative disorders (e.g. cancer), vaccination, stimulation of the innate immune response and boosting of the activity of endogenous NK cells.
本发明公开了具有以下式的孤立免疫调节(例如免疫刺激)多羟基吡咯烷化合物。在这些化合物中,R从氢,直链或支链,未取代或取代,饱和或不饱和酰基,烷基(例如环烷基),烯基,炔基和芳基中选择。这些化合物在治疗和预防中很有用,包括增加Th1:Th2反应比,血液恢复,减轻免疫抑制,细胞因子刺激,治疗增殖性疾病(例如癌症),接种,刺激先天免疫反应和提高内源性NK细胞的活性。
