KHS101 is a blood-brain barrier-penetrant anticancer agent that primarily functions by inhibiting HSPD1 (IC₅₀ = 14.4 μM) and TACC3 across different cellular backgrounds. KHS101 promotes the aggregation of HSPD1 with client proteins, destabilizes TACC3, and reduces the levels of TACC3, Aurora A and PLK1. KHS101 induces autophagy, apoptosis, cell cycle exit and neuronal differentiation; it suppresses cancer cell growth, motility, EMT and stemness; it also impairs mitochondrial bioenergetics and glycolysis in glioblastoma cells. KHS101 can be used in research related to glioblastoma multiforme and breast cancer.

Cucurbitacin D is the active ingredient in Trichosanthes kirilowii and can disrupt the interaction between Hsp90 and two co-chaperones, Cdc37 and p23. Cucurbitacin D is an inflammasome activator. Cucurbitacin D induces cell cycle arrest and cell apoptosis, exhibiting anti-tumor and anti-inflammatory effects.

EC144 is a potent and selective inhibitor of heat shock protein 90 (Hsp90) with an IC₅₀ of 1.1 nM. EC144 inhibits tumor growth and causes partial tumor regressions. EC144 has the potential for the research of cancer diseases. EC144 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Debio 0932 (CUDC-305) is an orally active HSP90 inhibitor, with IC₅₀s of 100 and 103 nM for HSP90α and HSP90β, respectively.

NMS-E973 is a potent and selective inhibitor of HSP90. NMS-E973 binds to the ATP binding site of Hsp90α with a DC₅₀ of <10 nM. NMS-E973 is able to cross the blood-brain barrier (BBB). Antitumor efficacy.

VER-49009 is a Hsp90 inhibitor, with an IC₅₀ of 25 nM and a K_d of 78 nM.

Neoisoliquiritin (Neoisoliquiritigenin) is an androgen receptor (AR) inhibitor. Neoisoliquiritin inhibits the ATPase activity of GRP78. Neoisoliquiritin induces G₀/G₁ cell cycle arrest and inhibits proliferation in cancer cells, while it also induces cell apoptosis (apoptosis). Neoisoliquiritin suppresses tumor growth in mouse models of prostate cancer and breast cancer. Neoisoliquiritin can be used in studies related to prostate cancer and breast cancer.

2-O-β-D-Glucopyranosyl-L-ascorbic acid (AA-2βG) is an orally active vitamin C derivative. 2-O-β-D-Glucopyranosyl-L-ascorbic acid exhibits multiple activities including antioxidant, anti-tumor and immunomodulatory effects. 2-O-β-D-Glucopyranosyl-L-ascorbic acid mediates tumor cell apoptosis, induces cell cycle arrest, scavenges free radicals and eliminates oxidative stress. 2-O-β-D-Glucopyranosyl-L-ascorbic acid can be used in studies related to cancer, inflammation and immunity.

Zelavespib (PU-H71) hydrochloride is a potent Hsp90 inhibitor, with an IC₅₀ of 51 nM in MDA-MB-468 cells.

Geldanamycin-FITC, a Geldanamycin fluorescent probe, can be used in a fluorescence polarization assay for HSP90 inhibitors. Geldanamycin-FITC also can be used for detection of cell surface HSP90 (Ex/Em = 488/515 nm).

AT-533 is a potent Hsp90 and HSV inhibitor. AT-533 suppresses tumor growth and angiogenesis by blocking the HIF-1α/VEGF/VEGFR-2 signaling pathway. AT-533 also inhibits the activation of the downstream pathways, including Akt/mTOR/p70S6K, Erk1/2 and FAK. AT-533 inhibits the tube formation, cell migration, and invasion of human umbilical vein endothelial cells (HUVECs).
