生物活性:
HLI373 is an efficacious Hdm2 inhibitor. HLI373 inhibits the ubiquitin ligase activity of Hdm2. HLI373 is effective in inducing apoptosis of several tumor cells that are sensitive to DNA-damaging agents. Antimalarial activity.
体外研究:
HLI373 (3-15 μM; 15 hours) selectively kills tumor cells harboring wild type p53.HLI373 (10-50 μM) stabilizes cellular Hdm2 in a dose-dependent manner. HLI373 (3 μM) activates p53 transcription.HLI373 selectively inhibits auto-ubiquitylation of Hdm2.Co-transfection with plasmids encoding p53 and Hdm2 results in degradation of p53. Incubation with HLI373 (5-10 μM; 8 hours) blocks p53 degradation. HLI373 increases p53 and Hdm2 protein levels in cells. HLI 373 also shows lower IC50 values (below 6 μM) against both chloroquine-sensitive P. falciparum D6 strain (PfD6) and chloroquine-resistant P. falciparum W2 strain (PfW2) and exhibits early growth inhibition. HLI-373 is a MDM2 inhibitor interrupting its ubiquitin E3 ligase activity, could abolish the ubiquitylation of its substrate protein p53. HLI-373 targets the C-terminus functioning as an E3 ubiquitin ligase.
