LYRM03
LYRM03 is a derivative of Ubenimex (HY-B0134) and a Aminopeptidase N inhibitor. LYRM03 is isolated from Streptomyces HCCB10043. LYRM03 inhibits TLR4, MyD88, NLRP3, ASC, NF-κB and p38 MAPK, stabilizes IκB, and suppresses LPS-induced expression of iNOS and COX-2. LYRM03 reduces the levels of inflammatory cytokines and oxidative stress markers, and alleviates pulmonary edema. LYRM03 exhibits anticancer activity against breast cancer. LYRM03 has anti-inflammatory activity. LYRM03 can be used in the research of acute lung injury and breast cancer.
