Photoreleasable compounds comprising a caging moiety linked to an effector moiety represented by structural formula (I) wherein R1 is hydrogen; C1-10 alkyl or substituted alkyl; O(CH2)n—Y; N(COZ)(CH2)mY; or N[(CH2)mY′[(CH2)NY]; R2 and R3 are independently selected from: hydrogen; C1-10 alkyl or substituted alkyl; or R2 and R3 together are cycloalkyl; R4 is hydrogen; C1-10 alkyl or substituted alkyl; phenyl or substituted phenyl; (CH2)nY; or (CH2)mO(CH2)nY; wherein m and n are independently between 1 and 10; Y and Y′ are independently selected from hydrogen, CO2H or salts thereof or OPO32−, Z is hydrogen or C1-10 alkyl or substituted alkyl; and, X is an effector moiety or a group capable of being coupled or converted to an effector moiety, which are capable of releasing the effector moiety on irradiation, typically by flash irradiation with UV light. The photoreleasable compounds can therefor be used to deliver biologically active effector moieties such as neuroactive amino acids or metal chelators to sites where their activity is required.
含有一个与结构式(I)所代表的效应子结构式相连的光释放化合物,其中R1为氢;C1-10烷基或取代烷基;O(CH2)n—Y;N(COZ)(CH2)mY;或N[(CH2)mY′[(CH2)NY]; R2和R3分别选择自:氢;C1-10烷基或取代烷基;或R2和R3一起为环烷基;R4为氢;C1-10烷基或取代烷基;苯基或取代苯基;(CH2)nY;或(CH2)mO(CH2)nY;其中m和n分别在1和10之间;Y和Y′分别选择自氢、CO2H或其盐或OPO32−,Z为氢或C1-10烷基或取代烷基;X为效应子或能够与效应子偶联或转化的基团,能够在照射下释放效应子,通常通过紫外光的闪烁照射。因此,这些光释放化合物可用于将生物活性效应子,如神经活性氨基酸或金属螯合剂,输送到需要其活性的部位。
