peptidomimetics. The drug release rates from this prodrug system were found to be dependent on the structural features of the drug moiety. In certain cases, the release can be undesirably slow for drugs that are secondary amines with relatively high pKa's. Aimed at finding ways to manipulate the release rates to suit the need of different drugs, we have examined the effect of the phenyl ring substitutions
最近在我们的实验室中开发了一种基于香豆素的前药系统,用于制备胺,肽和拟肽的酯酶敏感性前药。发现从该前药系统的药物释放速率取决于药物部分的结构特征。在某些情况下,对于具有较高pKa值的仲胺类药物,释放可能会缓慢地发生。为了找到控制释放速率以适应不同药物需求的方法,我们研究了苯环取代对此类前药释放动力学的影响,并发现在苯环上适当定位的烷基取代基可以帮助促进药物的释放。释放多达16倍。因此,
