Escin IA
Based on 1 publication(s) in Google Scholar
Escin IA is an oral LOXL2 inhibitor and EMT inhibitor, with selectivity for LOXL2-expressing cells. Escin IA suppresses invasion, migration, and metastasis of breast cancer cells, and acts as the primary anti-TNBC metastasis constituent of Aesculus chinensis Bunge fruit saponin fraction. Escin IA can be used for the research of triple-negative breast cancer, acute inflammation, and ethanol-induced gastric mucosal lesions.
