5)P(3)] receptors may be related to an alteration in the position of its 2'-phosphate group relative to the corresponding 1-phosphate group in Ins(1,4,5)P(3). To investigate this possibility, two bicyclic trisphosphates 9 and 10, designed to explore the effect of relocating the 1-phosphate group of Ins(1,4,5)P(3) using a novel fused-ring system, were synthesized from myo-inositol. Biological evaluation
腺苷A对1D-肌醇1,4,5-三磷酸[Ins(1,4,5)P(3)]受体的高亲和力可能与其2'-磷酸基团的位置改变有关相对于Ins(1,4,5)P(3)中相应的1-磷酸基团。为了研究这种可能性,从肌球蛋白合成了两个双环三磷酸三磷酸酯9和10,旨在探索使用新型稠合环系统重新定位Ins(1,4,5)P(3)的1-磷酸基团的效果。肌醇。对肝细胞的Ins(1,4,5)P(3)受体进行9和10的生物学评估表明,两者均被肝Ins(1,4,5)P(3)受体识别并且都刺激了Ca( 2+)来自细胞内存储,但它们的亲和力低于Ins(1,4,5)P(3)。
