  变力性的“ A”环取代的舒马唑和异唑类似物。

  摘要：

  已经制备了一系列“ A”环取代的舒马唑和异咪唑类似物，并评价为正性肌力药。测量所选化合物的pKA，质子化位点和log P值，并计算其电子性能。在正性肌力活动与pKA，质子化位点或log P值之间未发现简单的相关性。但是，体外变力性确实与“ B”环咪唑氮原子的电荷密度相关。舒马唑的6-位似乎对取代基具有最高的耐受性，6-氨基衍生物7比舒马唑本身更有效。4-甲氧基异唑13具有与异唑相当的体内正性肌力。

• Discovery of 3,3‘-(2,4-Diaminopteridine-6,7-diyl)diphenol as an Isozyme-Selective Inhibitor of PI3K for the Treatment of Ischemia Reperfusion Injury Associated with Myocardial Infarction

  In studies aimed toward identifying effective and safe inhibitors of kinase signaling cascades that underlie ischemia/reperfusion (I/R) injury, we synthesized a series of pteridines and pyridopyrazines. The design strategy was inspired by the examination of naturally occurring PI3K inhibitors such as wortmannin and quercetin, and building a pharmacophore-based model used for optimization. Structural modifications led to hybrid molecules which incorporated aminopyrimidine and aminopyridine moieties with ATP mimetic characteristics into the pharmacophore motifs to modulate kinase affinity and selectivity. Elaborations involving substitutions of the 2 and 4 positions of the pyrimidine or pyridine ring and the 6 and 7 positions of the central pyrazine ring resulted in in vivo activity profiles which identified potent inhibitors of vascular endothelial growth factor (VEGF) induced vascular leakage. Pathway analysis identified a diaminopteridine-diphenol as a potent and selective phosphatidylinositol-3-kinase (PI3K) inhibitor. The structure -activity relationship studies of various analogues of diaminopteridine-diphenol-based on biochemical assays resulted in potent inhibitors of PI3K.
