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.

ML346 is a novel activator of Hsp70.

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.

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.
