nsc145366

NSC145366 is an inhibitor of Hsp90 activities which targets the Hsp90 C-terminal domain to induce allosteric inhibition and selective client downregulation. NSC145366 increases Hsp90 oligomerization resulting in allosteric inhibition of NTD ATPase activity (IC50=119μM) but does not compete with NTD or CTD-ATP binding.

DNJNAc（亦称 2-Acetamido-1,2-dideoxynojirimycin）是一种高效且特异性的 β-己糖胺酶 (HEX) 抑制剂。HEX 酶催化糖蛋白、神经节苷脂及糖胺聚糖等糖结合物中末端非还原 N-乙酰-β-D-葡萄糖胺 (GlcNAc) 和 N-乙酰-β-D-半乳糖胺 (GalNAc) 的水解。软骨细胞分泌的 HEX 进入细胞外空间，可导致软骨基质降解，使骨关节炎滑液中的 HEX 活性升高。
