AbstractFive new homorubin analogs of bilirubin with their two dipyrrinone components conjoined to (CH2)2, (CH2)3, and (CH2)4 units were synthesized with propionic acid chains shortened to acetic and elongated to butyric, and examined by spectroscopy and molecular mechanics computations for an ability to form conformation-determining hydrogen bonds. With m designating the number of conjoining CH2 units
摘要合成了五个新的胆红素高红素类似物,它们的两个二吡啶酮成分与(CH 2)2,(CH 2)3和(CH 2)4单元相连,丙酸链缩短为乙酸,延长为丁酸,并通过光谱法进行了研究和分子力学计算,以确定形成构象的氢键的能力。m表示连接的CH 2单元数,n表示链烷酸链的CH 2单元数(mn制备了(-),(2.1)-,(3.2)-,(4.2)-和(4.3)-山红蛋白,并与先前合成的(2.2)和(2.3)进行了比较,后者在CHCl 3中采用了分子内氢键构象。 图形概要
