Substitution at the 7-position of the chromen-4-one pharmacophore of 8-(dibenzo[b,d]thiophen-4-yl)-2-morpholino-4H-chromen-4-one NU7441, a potent and selective DNA-dependent protein kinase (DNA-PK) inhibitor, with allyl, n-propyl or methyl enabled the resolution by chiral HPLC of atropisomers. Biological evaluation against DNA-PK of each pair of atropisomers showed a marked difference in potency, with
取代在7位的chromen-4-one药效基团上 8-(二苯并[ b,d ]噻吩-4-基)-2-吗啉代-4 H-铬烯-4-一NU7441是一种有效的,选择性的DNA依赖性蛋白激酶(DNA-PK)抑制剂,具有烯丙基,正丙基或甲基,可以通过手性HPLC拆分阻转异构体。对每一对阻转异构体的DNA-PK的生物学评估显示,其效价存在显着差异,而生物学活性仅存在于Laororotatory对映异构体中。
