Discovery of Novel KRAS-PDEδ Inhibitors by Fragment-Based Drug Design
摘要:
[Graphics]Targeting KRAS-PDE delta protein-protein interactions with small molecules represents a promising opportunity for developing novel antitumor agents. However, current KRAS-PDE delta inhibitors are limited by poor cellular antitumor potency and the druggability of the target remains to be validated by new inhibitors. To tackle these challenges, herein, novel, highly potent KRAS-PDE delta inhibitors were identified by fragment-based drug design, providing promising lead compounds or chemical probes for investigating the biological functions and druggability of KRAS-PDE delta interaction.

Pharmacological evaluation of imidazole‐derived bisphosphonates on receptor activator of nuclear factor‐κB ligand‐induced osteoclast differentiation and function
serious side‐effects can occur during the therapy. To search for novel potent BPs with lower side‐effects, a series of imidazole‐containing BPs (zoledronic acid [ZOL]; ZOL derivatives by substitution of the hydrogen at the 2‐position on the imidazole ring with a methyl [MIDP], ethyl [EIDP], n‐propyl [PIDP], or n‐butyl group [BIDP]) were developed and the effects on receptor activator of nuclear factor‐κB
双膦酸盐(BPs)已被广泛用于治疗溶骨性骨病变,如骨质疏松症和成骨不全症。然而,在治疗过程中可能会出现严重的副作用。为了寻找具有较低副作用的新型强效 BP,一系列含咪唑的 BP(唑来膦酸 [ZOL];通过用甲基 [MIDP]、乙基取代咪唑环上的 2 位氢的 ZOL 衍生物[EIDP]、正丙基 [PIDP] 或n丁基基团 [BIDP]) 被开发出来,并使用鼠巨噬细胞 RAW 264.7 细胞在蛋白质、基因、形态和功能水平上研究了对核因子-κB 配体 (RANKL) 诱导的破骨细胞分化的受体激活剂的影响。还研究了这些 BP 对 RAW 264.7 细胞生长和增殖的影响,以确定细胞毒性。结果表明,PIDP 在 12.5 μM 的浓度下以剂量依赖性方式显着抑制 RANKL 诱导的破骨细胞形成,而不会引起细胞毒性。它对肌动蛋白环的形成、骨吸收以及破骨细胞生成相关基因和蛋白质标志物的表达具有显着的抑制作用。c-Jun
