Eribulin Mesylate Injection is indicated for patients with locally advanced or metastatic breast cancer who have undergone at least two chemotherapy regimens and patients with unresectable or metastatic liposarcoma who have received treatment of anthracyclines. This compound contains 19 chirality centers and theoretically has 524,287 epimers. It involves more than 65 synthesis steps, which makes its synthesis exceedingly challenging.

Eribulin Mesylate Injection is one of the few products in China that have conducted the drug registration in China, the United States, and European countries. With API-preparation integrated production, it is highly competitive in mass API production and technical capabilities.
