DN401 is a potent TRAP1 and Hsp90 Inhibitor( IC50 = 79 nM for TRAP1, IC50 = 698 nM for Hsp90) with potent anticancer activity.

Rifabutin (LM-427) inhibits bacterial DNA-dependent RNA polymerase, thereby suppressing the initiation of RNA formation and leading to inhibition of RNA synthesis and transcription. Rifabutin is a semisynthetic ansamycin antibiotic with potent antimycobacterial properties.

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.

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

SNX2112 (PF 04928473) is an orally active Hsp90 inhibitor, with a Kd of 16 nM.

17-AEP-GA is an HSP90 antagonist, a potent inhibitor of glioblastoma cell proliferation, survival, migration, and invasion, and a toxic component of antibody-coupled activated molecules (ADCs), which can be used to study glioblastomas.

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

SNX0723 is a potent Hsp90 Inhibitor with anti-Plasmodium activity. SNX0723 shows high binding affinity for HsHsp90 and PfHsp90 with Kis of 4.4 and 47 nM, respectively. SNX0723 inhibits liver-stage P. berghei ANKA parasites with the EC50 of 3.3 μM.
