Bifunctional compounds, which find utility as modulators of Kirsten ras sarcoma protein (KRas or KRAS), are described herein. In particular, the hetero-bifunctional compounds of the present disclosure contain on one end a moiety that binds to the Von Hippel-Lindau E3 ubiquitin ligase and on the other end a moiety which binds KRas, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The heterobifunctional compounds of the present disclosure exhibit a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aberrant regulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

A proximity-driven covalent bond with intrinsically less reactive warheads has been made possible by using a metal-chelating anchor for directed targeted covalent modification of Cys165 within the BoNT/A protease.
A concise, transition-metal and protection-free synthesis of adagrasib (MRTX849), a novel KRASG12C inhibitor drug recently approved by the FDA, is reported. Introduction of two chiral building blocks to the tetrahydropyridopyrimidine core was accomplished via two sequential SNAr reactions. Extensive reaction optimization led to a robust, transition-metal-free oxidation of the sulfide intermediate.
报道了最近获得 FDA 批准的新型 KRAS G12C抑制剂药物adagrasib (MRTX849)的简明、过渡金属和无保护合成。将两个手性结构单元引入四氢吡啶并嘧啶核是通过两个连续的 S N Ar 反应完成的。广泛的反应优化导致硫化物中间体的稳健、无过渡金属氧化。在四氢吡啶并嘧啶核的 4-OH 位置明智地选择具有良好空间和电子特性的离去基团,可以轻松进行 S N Ar 置换,从而引入手性哌嗪。这种新的、五步、无层析的adagrasib合成从现成的起始材料中提取,避免了当前商业路线中的钯催化和保护基团操作,并显着提高了工艺效率,总收率为 45%。
