PhiKan 083 hydrochloride is a carbazole derivative, which binds to the surface cavity and stabilizes Y220C (a p53 mutant), with a Kd of 167 μM[1], and a relative binding affinity (Kd) of 150 μM in Ln229 cells[3]. Kd: 167 μM (p53-Y220C)[1], 150 μM (p53Y220C, in Ln229 cells)[3]
PhiKan 083 is a carbazole derivative, which binds to the surface cavity and stabilizes Y220C (a p53 mutant), with a Kd of 167 μM[1], shows a relative binding affinity (Kd) of 150 μM for p53Y220C in Ln229 cells[3].PhiKan 083 slows down its thermal denaturation rate[2].PhiKan 083 (125 μM, 48 hours) reduces the cell viability of engineered variants of Ln229 cells[3]. PhiKan 083 (100 μM) in conbination with doxorubicin (1 μM) enhances the pro-apoptotic activity in all variants of Ln229 cells (p53wt, p53Y220C, p53G245S, p53R282W)[3]. Cell Viability Assay[1] Cell Line: Ln229, Ln229-p53-wt, Ln229-p53-Y220C, Ln229-p53-G245S, Ln229-p53-R282W cells
