pharmacokinetic profile. Herein, we highlight the key insights made in the discovery program and detail the evolution of the structure–activity relationships (SARs) that led to the design of the specific C-17 amine moiety in 1. These modifications ultimately enabled the discovery of 1 as a second-generation MI that combines broad coverage of polymorphic viruses (EC50 <15 nM toward a panel of common polymorphisms
GSK3532795,以前称为BMS-955176(1),是一种有效的,口服活性的第二代HIV-1成熟抑制剂(MI),已通过IIb期临床试验。精心设计,选择和评估连接至天然产物桦木酸(3)C-3和C-17位置的取代基对于获得具有所需病毒学和药代动力学特征的分子至关重要。本文中,我们重点介绍了发现程序中的关键见解,并详细介绍了结构-活性关系(SAR)的演变,这些结构导致了特定C-17胺部分的设计[ 1]。这些修改最终使发现1作为第二代MI,结合了广泛的多态性病毒(对代表96.5%HIV-1 B型病毒的常见多态性而言,EC 50 <15 nM)与临床前物种中良好的药代动力学特征。
