生物活性:
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. 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.

体内研究:
TD52 (10 mg/kg/day; oral gavage; for 52 days) significantly inhibits MDA-MB-468 xenograft tumour size and tumour weight. Animal Model:Female NCr athymic nude mice (5-7 weeks of age)
Dosage:10 mg/kg
Administration:Oral gavage; daily; for 52 days
Result:Significantly inhibits MDA-MB-468 xenograft tumour size and tumour weight. Decreased the protein expressions of CIP2A and p-Akt in the three MDA-MB-468 xenograft tumours.

体外研究:
TD52 (2-10 μM; 48 hours) shows anti-proliferative ability and induces differential apoptotic effects in these cell lines. TD52 (5 μM; 48 hours) has minimal effects on p-EGFR or EGFR expression but downregulated CIP2A expression.TD52 (2.5, 5, 7.5 μM; 48 hours) time-dependently induces apoptosis accompanied with downregulating CIP2A and p-Akt. TD52 (5 μM; 24 hours) significantly increases the phosphatase activity of PP2A in TNBC cells. TD52 (5 μM; 48 hours) has no obvious effects on other common RTKs, such as IGFR, PDGFR and VEGFR2.
