MedKoo CAT#: 406116

CAS#: 170632-47-0

Description: Lificiguat, also known as YC-1, is a inhibitor of Hypoxia-inducible factor-1alpha (HIF-1alpha). YC-1 is widely used as a potent inhibitor of HIF-1alpha both in vitro and in vivo, and is also being developed as a novel anticancer drug. YC-1 effectively inhibits tumor invasion and metastasis, and imply that YC-1 is worth while to further develop as a multipurpose anticancer drug.
