of the esters of adenosine-5'-carboxylic acid, a systematic study of the corresponding amides (14--50) was undertaken. In addition, several other analogues containing the N1-oxide function (51--52) or 2',3' substituents (3--9, 53--54) were studied.
先前我们已经表明,腺苷5'-羧酸酯(10)代表了一类新的有效的无毒冠状血管扩张剂。例如,在犬中通过十二指肠内或静脉内途径具有活性的乙酯(12)会导致冠状窦PO2和冠状动脉血流大量增加。由于腺苷5'-羧酸的酯具有明显的血管活性,因此对相应的酰胺(14--50)进行了系统的研究。此外,还研究了其他几种含有N1-氧化物官能团(51--52)或2',3'取代基(3--9、53--54)的类似物。
