ML346 is a novel activator of Hsp70.

L-Alanyl-L-glutamine (Ala-Gln), a dipeptide composed of alanine and Gln, is an alternative supplement to L-glutamine in the production of biopharmaceuticals with better solubility and stability than glutamine (Gln).

SD-169 (SD 169) is a selective and ATP competitive the MAP kinases p38α and p38β inhibitor.

HM03 is a potent and selective inhibitor of HSPA5 and exhibits anticancer activity.

HEAT hydrochloride is an α1-adrenoceptor antagonist.

Heat shock protein (Hsp) inhibitor II is the active form of Hsp inhibitor I and a benzylidene lactam compound that prevents the synthesis of inducible Hsps, such as Hsp105, Hsp72, and Hsp40. Hsp inhibitor II decreases Hsp72 synthesis in vivo and reduces thermotolerance of tumors in SCC VII tumor-containing mice. At 100 μM, it inhibits the development of thermotolerance in COLO 320 DM cells. Inhibition of Hsp70 with Hsp inhibitor II in combination with amphotericin B increases susceptibility of AmB-susceptible (MICs = 0.058 versus 0.27 μg/ml for combined and AmB alone, respectively) and AmB-resistant (MICs = 21.33 versus >32 μg/ml for combined and AmB alone, respectively) strains of A. fumigatus.

Apoptozole (Apoptosis Activator VII) inhibits the ATPase domain of Hsc70 and Hsp70, inducing apoptosis.

TRC051384 is a heat shock protein 70 (HSP70) inducer that reduces stroke-associated neuronal damage and increases survival in a rat model of transient ischemic stroke, activates heat shock factor-1 and leads to elevated molecular chaperone and anti-inflammatory activity, and enhances Hsp72 expression in neurons and glial cells.

Pifithrin-μ (NSC-303580) is an inhibitor of p53 and HSP70, with neuroprotective and antitumor activity.

VER-155008 is an Hsp70 inhibitor (IC50 = 0.5 μM), exhibiting over 100-fold selectivity against Hsp90, and capable of inhibiting Hsc70 and Grp78 (IC50 = 2.6 μM for both). This compound possesses good selectivity and cell permeability, and is used in anti-tumor research, showing therapeutic potential in leukemia and solid tumor models.

Proteinase K (Protease K) is a non-specific serine protease that can tolerate changes in SDS, urea, pH (4-12), salt concentration, and temperature. Proteinase K hydrolyzes a wide range of peptide bonds and is used for protein digestion.

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

2-hexyl-4-Pentynoic Acid, a valproic acid (VPA) derivatives, is a potent and robust HDACs inhibitor with IC50 value of 13 μM.

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

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).

Col003 is a selective and potent inhibitor of Hsp47, competitively binding to the collagen-binding site on Hsp47 (IC50: 1.8 μM). It is useful for researching fibrosis.

Arimoclomol (BRX-220 free base), a co-inducer of heat shock proteins (HSP), is utilized in studies on the treatment of amyotrophic lateral sclerosis (ALS).

Arimoclomol maleate (BRX-220) (BRX-220) is a heat shock protein (HSP) co-inducer.

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.

Triptolide (PG490) belongs to the tricyclic diterpenoid group of natural products and is an inhibitor of NF-κB activation. Triptolide exhibits immunosuppressive, anti-rheumatic, anti-inflammatory, anti-proliferative and anti-tumor activities.

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.
