Retaspimycin is a potent and water-soluble Hsp90 inhibitor(EC50s of 119 nM for both Hsp90 and Grp9).

Palmitic acid-13C is intended for use as an internal standard for the quantification of palmitic acid by GC- or LC-MS. Palmitic acid-13C contains 13C at the C2 position and has been used in the study of free fatty acid incorporation into phospholipid fatty acids in soil microbes.1 Palmitic acid is a 16-carbon saturated fatty acid. It comprises approximately 25% of human total plasma lipids.2 It increases protein levels of COX-2 in RAW 264.7 cells when used at a concentration of 75 μM.3 Palmitic acid is involved in the acylation of proteins to anchor membrane-bound proteins to the lipid bilayer.3,4,5,6,7

Palmitic acid-16,16,16-d3 是 Palmitic acid 的氘代化合物。Palmitic acid 的 CAS 号为 57-10-3。Palmitic acid 是在动物、植物和微生物中发现的最常见的饱和脂肪酸，具有抗肿瘤活性。它可诱导小鼠颗粒细胞中葡萄糖调节蛋白 78 和 CCAAT/增强子结合蛋白同源蛋白的表达。

Hsp90-IN-37 (Z-2) 是一种热休克蛋白90（Hsp90）抑制剂，对Hsp90酶活性抑制率达到69%，并具有抗肿瘤活性。

KUNB31 is a potent and selective inhibitor of Hsp90β.

MK2-IN-5为Mk2的假底物，Ki值为8 μM。该化合物针对MAPK通路内的蛋白相互作用域，并能抑制HSP25与HSP27的磷酸化。

BF844 is a chemical compound that demonstrates the ability to mitigate hearing loss in individuals with Usher Syndrome Type III (USH3) caused by the CLRN1 mutation (specifically N48K). One of its mechanisms of action is the transportation of CLRN1 N48K to the plasma membrane. In vivo studies have shown that BF844 significantly preserves hearing [1].

4-Br-Bnlm 是葡萄糖调节蛋白 (Grp94) 的选择性抑制剂，EC50值为 0.96 µM。它能够减少突变心肌蛋白和野生型心肌蛋白在细胞中的错误折叠水平，并促进毒性心肌素的清除，从而降低心肌毒性。

HM03 trihydrochloride is a potent and selective inhibitor of HSPA5, also known as Bip or Grp78. It exhibits anticancer activity.
