The present invention relates to photolabile or photoreleasable compounds including a caging moiety linked to an effector moiety, wherein the compounds are capable of releasing the effector moiety on irradiation, typically by flash irradiation with UV light. These compounds are particularly suitable for focal 2-photon uncaging The photoreleasable compounds can be used to deliver effector moieties such as carboxylic acids, preferably, neuroactive amino acids to sites where their activity is required. In preferred embodiments of the invention, the caging moiety is based on 4-carboxymethoxy-5,7-dinitroinlinyl and derivatives thereof.
本发明涉及光敏感或光释放化合物,包括与效应基团连接的笼罩基团,其中这些化合物能够通过紫外光闪光照射来释放效应基团。这些化合物特别适用于局部二光子解笼。光释放化合物可用于将效应基团(例如
羧酸,优选为神经活性
氨基酸)输送到需要其活性的位置。在本发明的优选实施例中,笼罩基团基于4-羧甲氧基-5,7-二硝基印胺及其衍
生物。
