the ester side-chain configuration, in the nature of the 14-axial substituent (H, Me, Et) and in their absolute configuration, have been prepared. A pronounced trend towards increased Na+K+-ATPase inhibitory activity occurs through the H, Me and Et series, with the E side-chain configuration more active than the Z. This trend is largely confined to the analogues with an absolute configuration matching
已经制备了在酯侧链构型,14-轴取代基(H,Me,Et)的性质及其绝对构型方面不同的红血球生物碱类似物。通过H,Me和Et系列出现明显的Na + K + -ATPase抑制活性增加趋势,其中E侧链构型比Z活性高。这种趋势主要限于具有与天然生物碱相匹配的绝对构型的类似物。提出了生物碱的14轴烷基取代基和强心类固醇D环之间的结构平行关系。
