The present invention relates to compounds comprising an interleukin-1 receptor-associated kinase 1 (IRAK1) protein binding moiety and a Von Hippel-Lindau (VHL) E3 ubiquitin ligase binding moiety, and associated methods of use. The compounds are useful as modulators of targeted ubiquitination, especially with respect to IRAK1, which is degraded by the compounds according to the invention.

is a suitable bioisostere of the P3/P2 amide/proline for developing CtHtrA inhibitors. Most pyridone-based inhibitors showed superior anti-chlamydial potency to JO146 especially at lower doses (25 and 50 μM) in C. trachomatis and C. pecorum cell culture assays. Modifications of the N-capping group of the peptidyl inhibitors did not have much influence on the anti-chlamydial activities, providing opportunities
专性细胞内细菌沙眼衣原体( C. trachomatis ) 是最常见的细菌性性传播感染的原因,并且是可预防失明的主要原因,是全球主要的健康负担。虽然沙眼衣原体感染目前可以用广谱抗生素治疗,但衣原体特异性治疗会有很多好处。此前,我们已经确定了一种针对细菌丝氨酸蛋白酶 HtrA的小分子先导化合物JO146 [Boc-Val-Pro-Val P (OPh) 2 ],它对细菌的复制、毒力和生存至关重要,尤其是在压力条件下。JO146在体外和体内都非常有效地减弱人类(沙眼衣原体)和考拉(C. pecorum)物种的感染性,并且没有宿主细胞毒性。在此,我们展示了我们通过修改 N 封端基团以及在 P3/P2 处用 2-吡啶酮支架替换母肽结构来优化JO146的持续努力。药物优化过程由分子建模、酶和基于细胞的测定法指导。与 JO146 相比,吡啶酮系列化合物18b对 CtHtrA 的抑制活性提高了 5 倍,对人中性粒细胞弹性蛋白酶
