TD52, an Erlotinib (HY-50896) derivative, is an orally active, potent cancerous inhibitor of protein phosphatase 2A (CIP2A) inhibitor. TD52 mediates the apoptotic effect in triple-negative breast cancer (TNBC) cells via regulating the CIP2A/PP2A/p-Akt signalling pathway. TD52 indirectly reduced CIP2A by disturbing Elk1 binding to the CIP2A promoter. TD52 has less p-EGFR inhibition and has potent anti-cancer activity[1]. TD52 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
TD52, an erlotinib analog, is a putative inhibitor of CIP2A th at exhibits potent antitumor efficacy on HCC and TNBC cells. TD52 induces apoptosis through downregulation of CIP2A (Cancerous inhibitor of protein phosphatase 2A) in HCC, NSCLC and TNBC cells. Apparently TD52 indirectly downregulates CIP2A transcripts through interrupting the binding of Elk1 to CIP2A promoter. TD52 is a weak inhibitor of EGFR tyrosine kinase.
