Compound X10g (PROTAC Hsp90α degrader 1) is a selective agent targeting Hsp90α for degradation and is utilized in breast cancer research. It demonstrates inhibitory effects on the proliferation of breast cancer cell lines, MDA-MB-231, MDA-MB-468, MCF-7, and MX-1, with respective IC50 values of 51.48 μM, 16.46 μM, 8.93 μM, and 11.95 μM [1].

Tamoxifen (ICI47699) is a selective and orally effective estrogen receptor modulator (SERM). Tamoxifen has both inhibitory (e.g., mammary cells) and activating (e.g., bone, liver, and uterine cells) activity against estrogens.

Wighteone (Erythrinin B) is a small molecule compound derived from Genista ephedroides with potential antifungal and anticancer activity against EGFR L858R T790M mutant non-small cell lung cancer.

Tamoxifen is an antineoplastic nonsteroidal selective estrogen receptor modulator (SERM).

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.

Tanespimycin (KOS 953) (17-AAG) is an inhibitor of Hsp90 that selectively inhibits BT474 tumor cell Hsp90 (IC50: 5 nM).

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

AMP-PCP is an ATP analog and can bind to the Hsp90 N-terminal domain (Kd: 3.8 μM). AMP-PCP binding favors the formation of the active homodimer of Hsp90.

Radicicol (Monorden) is an antifungal antibiotic and a potent inhibitor of heat shock protein 90 (Hsp90), which leads to the degradation of Hsp90 by the proteasome by binding to its ATP-binding pocket. In addition, Radicicol inhibits the growth and proliferation of several tumor cell lines. It also has anti-malarial activity and acts as an inhibitor of adipose- and obesity-related proteins (FTO). Radicicol inhibits iNOS gene expression by blocking the p38 kinase signaling pathway and NF-kB Rel

CCT018159 is a 3,4-diarylpyrazole resorcinol, an ATP-competitive HSP90ATPase inhibitor that inhibits human Hsp90β and yeast Hsp90 with IC50s of 3.2 and 6.6 μM, respectively.CCT018159 inhibits key endothelial and tumor cell functions associated with invasion and angiogenesis. CCT018159 caused cellular inhibition associated with G1 phase block and induced apoptosis.

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.
