LLL3
Based on 1 publication(s) in Google Scholar
LLL3 (CLT-005) is a STAT3 inhibitor. LLL3 inhibits dimerization and phosphorylation of STAT3, thereby preventing intraconuclear transfer of STAT3 and inhibits the expression of STAT3 dependent genes, which encode proteins such as Bcl-xL and cyclin D1. In addition, LLL3 can induce cell growth inhibition and apoptosis in human breast cancer and rhabdomyosarcoma cells via the caspase pathway. LLL3 can be used in the study of STAT3 persistent activation types of cancer.
