Target	p300
In Vitro	CTB (10, 50, 100, 150, 200, and 250 µM; 10 min) enhances p300 HAT activity of p300 in a dosedependent manner[1]. CTB (0-200 μM; 24 hours) inhibits the viability of MCF-7 cells with an IC50 of 85.43 μM[2]. CTB (85.43 μM; 24, 48 and 72 h) induces time dependence apoptosis of MCF-7 cells[2]. CTB (50 uM; 24 h) increases p300/CBP activity , and reduces autophagic flux in primary neurons[3]. Cell Viability Assay[2] Cell Line: MCF-7 cell Concentration: 0-200 μM Incubation Time: 24 hours Result: Inhibit viability with an IC50 of 85.43 μM. Apoptosis Analysis[2] Cell Line: MCF-7 cell Concentration: 85.43 μM Incubation Time: 24, 48 and 72 h Result: Iinduced time-dependence apoptosis.
