New ester cages bearing the coumarin (2H-benzopyran-2-one) skeleton with extended π-systems as phototriggers, for glycine and β-alanine, as models of carboxylic acid bifunctional molecules with biological relevance, were evaluated under photolysis conditions at 254, 300, 350 and 419 nm of irradiation in a RPR-100 photochemical reactor. The processes were followed by HPLC-UV detection and 1H NMR with
在254的光解条件下,评估了带有香豆素(2 H-苯并吡喃-2-酮)骨架并具有扩展的π系统作为光触发的新酯笼,用于光触发的甘氨酸和β-丙氨酸作为具有生物相关性的羧酸双功能分子模型在RPR-100光化学反应器中照射300、350和419 nm。该过程之后进行HPLC-UV检测和1 H NMR,并收集动力学数据。结果表明,甘氨酸和β-丙氨酸的光解效率与共轭作用的增加扩展之间存在相关性,表明7-氨基香豆素在所有测试波长下均能提供最佳结果。 通过对时间分辨荧光行为的研究,还发现这些化合物表现出更复杂的荧光衰减动力学。这归因于共轭和非共轭香豆素种类的存在。

imidazole or triazole ring linked to a fluorene (A), indenodiazine (B), or coumarin scaffold (C) are reported. Properly substituted coumarin derivatives displayed the highest aromatase inhibitory potency and selectivity over 17-alpha-hydroxylase/17-20 lyase. The modeling of the aromatase inhibition data by Comparative Molecular Field Analysis (CoMFA/GOLPE 3D QSAR approach) led to the development of a PLS
报道了一系列新的芳香酶抑制剂的设计,合成和生物学评估,这些抑制剂带有与芴(A),茚并二嗪(B)或香豆素骨架(C)连接的咪唑或三唑环。与17-α-羟化酶/ 17-20裂解酶相比,正确取代的香豆素衍生物显示出最高的芳香酶抑制能力和选择性。通过比较分子场分析(CoMFA / GOLPE 3D QSAR方法)对芳香化酶抑制数据进行建模,导致了具有良好拟合和预测能力(n = 22,ONC = 3,r(2)= 0.949, s = 0.216,而q(2)= 0.715)。
