The present invention relates to prodrugs of protease inhibitors, such as inhibitors of proteosome, DPP IV, FAPα and the like. These "pro-inhibitors" are activated, i.e., cleaved by an "activating protease" to release an active inhibitor moiety in proximity to a "target protease". The identity of activating protease and target protease can be the same (such pro-inhibitors being referred to as "Target-Activated Smart Protease Inhibitors" or "TASPI") or different (e.g., "Target-Directed Smart Protease Inhibitors" or "TDSPI"). After activation of the pro-inhibitor, the active inhibitor moiety can self-inactivate by, e.g., intramolecular-cyclization or cis-trans isomerization.
本发明涉及蛋白酶抑制剂的原药,如蛋白酶体、DPP IV、FAPα 等的抑制剂。这些 "原抑制剂 "被激活,即被 "激活蛋白酶 "裂解,从而在 "靶蛋白酶 "附近释放出活性抑制剂分子。激活蛋白酶和靶蛋白酶的身份可以相同(这种原抑制剂被称为 "靶激活智能蛋白酶抑制剂 "或 "TASPI"),也可以不同(例如,"靶定向智能蛋白酶抑制剂 "或 "TDSPI")。激活原抑制剂后,活性抑制剂分子可通过分子内环化或顺反异构等方式自我失活。
