Chetomin, an active component of Chaetomium globosum, is a heat shock protein 90/hypoxia-inducible factor 1 alpha (Hsp90/HIF1α) pathway inhibitor. Chetomin is a potent, nontoxic non-small cell lung cancer cancer stem cells (NSCLC CSC)-targeting molecule[1].

In Vitro	Chetomin (0~10 μM; 24 hours; H460 and H1299 cells) shows progressively lower expression of several survival-promoting proteins promoted by Hsp90/HIF1α activity, including insulin-like growth factor 1 (IGF1 R), epidermal growth factor receptor (EGFR), Src, mitogen-activated protein kinase kinase 1/2 (MEK1/2), activation of protein kinase B (Akt), and mammalian target of rapamycin (mTOR) [1]. Chetomin (0~10 μM; 24 hours; H1299 cells) elicits cell cycle arrest in susceptible and chemoresistant NSCLC cell lines[1]. .Chetomin (1 µM; 3 days; H460 and H1299 cells) pretreatment abolishes their sphere-forming capacity. Chetomin inhibits sphere-forming by NSCLC CSCs within a nanomolar range, and proliferation of susceptible and chemoresistant NSCLC non-CSCs within a micromolar range. Chetomin (24 h) decreases HIF-response element activity in H460 and H1299 monolayer cultures. Chetomin (0~10 μM) specifically inhibits the Hsp90-HIF1α binding interaction in HIF1α's N-terminus [1]. Western Blot Analysis[1] Cell Line: H460 and H1299 cells Concentration: 0~10 μM Incubation Time: 24 hours Result: Showed progressively lower expression of several survival-promoting proteins promoted by Hsp90/HIF1α activity, including insulin-like growth factor 1 (IGF1 R), epidermal growth factor receptor (EGFR), Src, mitogen-activated protein kinase kinase 1/2 (MEK1/2), activation of protein kinase B (Akt), and mammalian target of rapamycin (mTOR). Cell Cycle Analysis[1] Cell Line: H1299 cells Concentration: 0~10 μM Incubation Time: 24 hours Result: Elicited cell cycle arrest in susceptible and chemoresistant NSCLC cell lines.
In Vivo	Chetomin (0~100 mg/kg; p.o.) inhibits lung tumorigenesis in NSCLC mouse models[1]. .Chetomin markedly decreases tumor formation in several murine models of NSCLC[1]. Animal Model: Mouse Dosage: 0~100 mg/kg Administration: P.o. Result: Inhibited lung tumorigenesis in NSCLC mouse models.
