The stereochemistry around the N‐benzoylated indole moiety of indometacin was studied by restricting the rotation about the NC7′ and/or C7′C1′ bond. In the 2′,6′‐disubstituted ones, an atropisomeric property was found and the atropoisomers were separated and isolated as stable forms. Their biological abilities to inhibit cyclooxygenase‐1 (COX‐1) and cyclooxygenase‐2 (COX‐2) were examined. Only the
周围的立体化学Ñ -benzoylated吲哚美辛的吲哚部分,通过限制约的N个旋转研究 C7'和/或C7' C1'键。在2',6'-双取代的分子中,发现其阻转异构性质,并且将其阻转异构体分离并分离为稳定形式。检查了它们抑制环氧合酶-1(COX-1)和环氧合酶-2(COX-2)的生物学能力。仅a R异构体显示出对COX-1的特异性抑制,而COX-2均不受任何阻转异构体的抑制。NMR研究和X射线晶体学中的构象分析以及CD光谱与计算相结合来阐明生物活性构象。
