求翻译:Simply changing the carboxyl group at C-28 position into methyl (4) and hydroxyl group (10a) decreased the activity below the threshold value (>20 lM), which indicated that the presence of carboxyl group was vital to the PTP1B inhibitory potency. It was also proved by amide (10f–h) or ester (10i and 10j) substitution c是什么意思?

简单地改变成甲基(4)和羟基(10A)C-28位置的羧基下降低于阈值(> 20流明),这表明羧基的存在是至关重要的PTP1B抑制效力的活动。它也证明了酰胺(10F-H)或酯(10I和10J)取代化合物。以往的研究表明,保持适当的拉长磷酸盐模仿,进入催化芳基域附近设计有竞争力的PTP1B抑制剂的重要原则之一。 10B及10K,其中具有去除苯和取代酰胺化合物10C肯定是少有力验证了这条规则。如此,10K碳链长度在2,4,6,8,10,12-10P化合物合成,分别找到合适的长度。相应的结果表明,拉长系列的抑制效力低的加速,随着的逐渐增加长度,这表明,化合物4-6碳链长度适合进一步优化,由于其生

只需更改carboxyl组c28位置到甲基(4)和羟基组(10a)减少了活动低于阈
