Inhibition of intestinal carboxylesterases may allow modification of the pharmacokinetics/pharmacodynamic profile of existing drugs by altering half-life or toxicity. Since previously identified diarylethane-1,2-dione inhibitors are decidedly hydrophobic, a modified dione scaffold was designed and elaborated into a >300 member library, which was subsequently screened to establish the SAR for esterase inhibition. This allowed the identification of single digit nanomolar hiCE inhibitors that showed improvement in selectivity and measured solubility.
抑制肠道羧酸酯酶可能通过改变半衰期或毒性来改变现有药物的药代动力学/药效学特征。由于先前确定的二芳基乙烷-1,2-二酮抑制剂是明显的疏水性的,因此设计了一种改良的二酮支架并将其精心设计成一个包含>300 个成员的文库,随后对其进行筛选以确定酯酶抑制的 SAR。这使得能够鉴定出单个数字纳摩尔级的 hiCE 抑制剂,这些抑制剂显示出改善的选择性和可测量的溶解度。
