Onalespib

Onalespib (AT13387) is an orally available small molecule Hsp90 inhibitor with antineoplastic potential. It disrupts Hsp90's chaperone function, leading to the degradation of client oncoproteins critical for tumor survival. This compound has demonstrated activity in preclinical studies across various cancer models, supporting its investigation in oncology research.
