HSP
Heat shock proteins
HSP (Heat shock proteins) are a group of proteins induced by heat shock, the most prominent members of this group are a class of functionally related proteins involved in the folding and unfolding of other proteins. HSP expression is increased when cells are exposed to elevated temperatures or other stress. This increase in expression is transcriptionally regulated. The dramatic upregulation of the heat shock proteins is a key part of the heat shock response and is induced primarily by heat shock factor (HSF). HSPs are found in virtually all living organisms, from bacteria to humans. Heat shock proteins appear to serve a significant cardiovascular role. Hsp90, Hsp84, Hsp70, Hsp27, Hsp20 and alpha B crystallin all have been reported as having roles in the cardiovasculature.

Alvespimycin hydrochloride
0 ImagesSynonyms: 17-DMAG hydrochloride; KOS-1022 hydrochloride; BMS 826476
-
JG-98
0 ImagesJG-98, an allosteric heat shock protein 70 (Hsp70) inhibitor, which binds tightly to a conserved site on Hsp70 and disrupts the Hsp70-Bag3 interaction. JG-98 shows anti-cancer activities affecting both cancer cells and tumor-associated macrophages.
-
HSP27 inhibitor J2
0 ImagesSynonyms: J2HSP27 inhibitor J2 (J2) is a HSP27 inhibitor, which significantly induces abnormal HSP27 dimer formation and inhibits a production of HSP27 giant polymers, thereby having an effect of inhibiting a chaperone function of the HSP27 and reducing a cell protection function thereof. HSP27 inhibitor J2 (J2) remarkably enhances the antiproliferative activity of 17-AAG and sensitizes cisplatin-induced lung cancer cell growth inhibition.
-
Radicicol
0 ImagesSynonyms: MonordenRadicicol is an inhibitor of Hsp90 with an IC50 value < 1 μM, and leads to proteasomal degradation. Radicicol exhibits inhibition on PDK with IC50s of 230 μM (PDK1) and 400 μM (PDK3). Radicicol is an antifungal and antimalarial antibiotic, impairs mitochondrial replication by targeting P. falciparum topoisomerase VIB. Radicicol is also an inhibitor of fat mass and obesity-associated protein (FTO), with an IC50 value of 16.04 μM.
-
SNX-2112
0 ImagesSynonyms: PF-04928473SNX-2112 (PF 04928473) is an orally active Hsp90 inhibitor, with a Kd of 16 nM for Hsp90 and IC50s of 30 nM, 30 nM for Hsp90 α and Hsp90 β, also induces Her-2 degradation, and inhibits Grp94 and Trap-1, with IC50s of 10 nM, 4.275 μM and 0.862 μM, respectively. SNX-2112 (PF 04928473) binds Hsp90 isoforms Hsp90α, Hsp90β and Hsp90b1/Grp94 with Kds of 4 nM, 6 nM and 484 nM, respectively.
-
YUM70
0 ImagesYUM70 is a potent and selective inhibitor of glucose-regulated protein 78 (GRP78), with an IC50 of 1.5 μM for inhibiting GRP78 ATPase activity of the full-length protein. YUM70 induces endoplasmic reticulum (ER) stress-mediated apoptosis in pancreatic cancer. YUM70 also has in vivo efficacy in a pancreatic cancer xenograft model.
-
Grp94 Inhibitor-1
0 ImagesGrp94 Inhibitor-1 is a potent, selective Grp94 inhibitor with an IC50 value of 2 nM, and over 1000-fold selectivity to Grp94 against Hsp90α.

KW-2478
0 ImagesKW-2478 is an HSP90 inhibitor (IC50 = 3.8 nM). KW-2478 inhibits the growth and induces apoptosis in chronic myeloid leukemia (CML) cells and liver cancer cells. KW-2478 weakens the BCR/ABL and MAPK signaling pathways, leading to increased p27 and p21 expression and decreased cyclin B1 expression. KW-2478 downregulates STAT3 expression. KW-2478 may be used in research on cancers such as CML and liver cancer.
-
HM03
0 ImagesHM03 is a potent and selective HSPA5 (Heat shock 70kDa protein 5, also known as Bip, Grp78) inhibitor. HM03 has anticancer activity.

Dihydroberberine
0 ImagesDihydroberberine is a naturally occurring isoquinoline alkaloid with anti-inflammatory, anti-atherosclerotic, hypolipidemic and anti-tumor activities. Dihydroberberine inhibits the human ether-related gene (hERG) channel and significantly reduces the expression of heat shock protein 90 (Hsp90) and its interaction with hERG. Dihydroberberine also blocks the TLR4/MyD88/NF-κB signaling pathway to reduce pro-inflammatory cytokines and immunoglobulins, and has inhibitory effects on DSS (HY-116282C)-induced experimental colitis. Dihydroberberine also increases the sensitivity of lung cancer to sunitinib (HY-10255A), with synergistic efficacy.
