To explore the biological significance of the D-3 position phosphorylation of the second messenger D-myo-inositol 1,4,5-trisphosphate (IP3) in cellular signalling, three novel D-3-substituted analogues of IP3 have been synthesized; their binding and Ca2+-release profiles at the IP3-receptor have been studied and shown to correlate with the steric requirement of the D-3 substituent.
为了探索第二信使 D-肌醇-1,4,5-
三磷酸酯(IP3)的 D-3 位
磷酸化在细胞信号传导中的
生物学意义,我们合成了三种新型 D-3 取代的 IP3 类似物;我们研究了它们在 IP3 受体上的结合和 Ca2+ 释放情况,结果表明它们与 D-3 取代基的立体要求相关。
