A series of new analogues of 1-beta-D-ribofuranosylbenzimidazole 3',5'-phosphate (cBIMP) has been designed according to the properties predicted by the MNDO method, and synthesised from substituted benzimidazoles. Dipole vectors and HOMO and LUMO energies for each benzimidazole base were calculated by the MNDO method and the lipophilicities of the cBIMP derivatives were determined. In general, the
根据MNDO方法预测的性质,设计了一系列1-β-D-呋喃呋喃糖基苯并咪唑3',5'-磷酸酯(cBIMP)的新类似物,并由取代的苯并咪唑合成。通过MNDO方法计算每个苯并咪唑碱基的偶极子向量以及HOMO和LUMO能量,并确定cBIMP衍生物的亲脂性。通常,cBIMP衍生物激活cAMP依赖性蛋白激酶I和II,并优先结合位点B,特别是对于II型激酶,其中2-三氟甲基-cBIMP和5,6-二氟-cBIMP表现出最高的位点选择性。每个cBIMP衍生物都可以刺激cGMP刺激的环磷酸二酯酶(cGS-PDE),其中5,6-二甲基-cBIMP与cGMP一样有效,并且还可以抑制cGMP抑制的磷酸二酯酶(cGI-PDE)。仅2-三氟甲基-cBIMP和Rp-硫代磷酸酯(cBIMPS)(赤道P = S)对cPDE的水解具有抗性。如果有的话,将Sp-硫代磷酸酯缓慢水解。除了表现出高亲脂性外,用于诱导细胞凋亡和抑制增殖
