Provided are omecamtiv mecarbil dihydrochloride salt forms, compositions and pharmaceutical formulations thereof, and methods for their preparation and use.

Provided are omecamtiv mecarbil dihydrochloride salt forms, compositions and pharmaceutical formulations thereof, and methods for their preparation and use.

Disclosed is a compound as shown in formula (I) or a pharmaceutically acceptable salt, a stereoisomer, an isotope derivative or a prodrug thereof. The compound has an excellent activity as a cyclin-dependent kinase 9 (CDK9) inhibitor for treating hyperproliferative diseases. The experimental research on in vitro inhibition of cell proliferation and in vivo suppression of tumors shows that such compounds have a relatively strong inhibitory effect on MV4;11 cells and in vivo tumor models, and have a good selectivity and a low toxicity and few side effects, thereby possessing a good clinical value as novel anti-tumor drugs.
