heat shock proteins

ML346 is a novel activator of Hsp70.

VER-155008 is a potent Hsp70 family inhibitor with IC50 of 0.5 μM, 2.6 μM, and 2.6 μM in cell-free assays for HSP70, HSC70, and GRP78, respectively, >100-fold selectivity over HSP90.

Ethoxyquin (Santoflex) is an antioxidant used in animal feeds.

Palmitic acid (Cetylic acid) is a natural product, a common saturated fatty acid found in animals, plants and microorganisms. Palmitic acid has antitumor activity.

Teprenone (Geranylgeranylacetone) is a anti-ulcer drug, and works as an inducer of heat shock proteins (HSPs).

Onalespib (AT13387) is a synthetic, orally bioavailable, small-molecule inhibitor of heat shock protein 90 (Hsp90) with potential antineoplastic activity. Onalespib selectively binds to Hsp90, thereby inhibiting its chaperone function and promoting the degradation of oncogenic signaling proteins involved in tumor cell proliferation and survival. Hsp90, a chaperone protein upregulated in a variety of tumor cells, regulates the folding, stability and degradation of many oncogenic signaling proteins.

Alvespimycin hydrochloride (BMS 826476) is a potent HSP90 inhibitor with IC50 of 62 nM. Phase 2.

Pimitespib (TAS-116) is an ATP-competitive and highly specific HSP90α/HSP90β inhibitor with inhibition constants (Kis) of 34.7 nM and 21.3 nM, respectively.

Luminespib (VER-52296) is an HSP90 inhibitor that inhibits HSP90α and HSP90β (IC50=7.8/21 nM). Luminespib has antitumor activity and is used in studies of head and neck tumors, among others.

VER-82576 (NVP-BEP800), a synthetic HSP90β inhibitor (IC50: 58 nM), exhibits >70-fold selectivity against Hsp90 family members Trap-1 and Grp94.

Gedunin is an important limonoid present in several genera of the Meliaceae family, mainly in seeds. Gedunin is an Hsp90 inhibitor, and inhibits ovarian cancer cell proliferation.

BIIB021 (CNF2024) is an orally-available, fully synthetic inhibitor of HSP90(Ki=1.7 nM, EC50=38 nM).

HSP70-IN-1 is a heat shock protein (HSP) inhibitor that suppresses the growth of Kasumi-1 cells with an IC50 of 2.3 μM.

JG-98 is an allosteric Hsp70 inhibitor, displays high active against the breast cancer cell lines MDA-MB-231 and MCF-7 (EC50s: 0.4/0.7 μM).

Eupalinolide B is a natural product ,and demonstrates potent cytotoxicity against A-549, BGC-823, SMMC-7721, and HL-60 tumour cell lines.

NVP-HSP990 (HSP990) is an effective and specific HSP90α/β inhibitor (IC50: 0.6 /0.8 nM).

XL888 is an ATP-competitive inhibitor of Hsp90 ( IC50: 24 nM). Heat shock protein 90 (Hsp90) is a chaperone that maintains the functionality of client proteins involved in cell proliferation, cell cycling, and apoptosis. Through this action, specific clie

Tanespimycin (KOS 953) is an Hsp90 inhibitor (IC50=5 nM) and is selective. Tanespimycin depletes intracellular STK38/NDR1 and decreases STK38 kinase activity. Tanespimycin also downregulated stk38 gene expression.

NMS-E973 is a potent and selective Hsp90 inhibitor with a DC50 of less than 10 nM for Hsp90 binding, displaying no activity against a panel of 52 diverse protein kinases.

HSP27 inhibitor J2 (J2) (J2) is a HSP27 inhibitor, 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.

YUM70 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. It induces endoplasmic reticulum (ER) stress-mediated apoptosis in pancreatic cancer.

Calenduloside E (Silphioside F) exhibits hypoglycemic activities by suppressing the transfer of glucose from the stomach to the small intestine and by inhibiting glucose transport at the brush border of the small intestine in oral glucose-loaded rats.

Azadiradione (AZD) (AZD) from the methanolic extract of seeds of Azadirachta indica

Paeoniflorin (Peoniflorin) is a herbal constituent extracted from the root of Paeonia albiflora Pall.
