生物活性:
Mcl-1 inhibitor 3 (compound 1) is a highly potent and orally activate macrocyclic Mcl-1 inhibitor (Ki= 0.061 nM; IC50=19 nM in an OPM-2 cell viability assay). Mcl-1 inhibitor 3 shows good pharmacokinetic properties and excellent in vivo efficacy without toxicity..

体内研究:
Mcl-1 inhibitor 3 (oral administration; 3, 10, or 30 mg/kg; 6 hours) causes a significant loss of luminescence (~40%) over vehicle at 30 mg/kg,This effect was observed with unbound drug levels in plasma, the [plasma]u/OPM-2 IC50 values are 0.24, 0.93 and 3.65 μM in 3, 10, 30 mg/kg doses,respectively.Mcl-1 inhibitor 3 (oral administration; 10, 30, or 60 mg/kg; 6 hours) activates Bak by 8-fold at 30 mg/kg and by 14-fold at 60 mg/kg in this OPM-2 Luc assay,this test is based on the detection of activated Bak in nude mice subcutaneously injected with via electrochemiluminescence..Mcl-1 inhibitor 3 (oral administration; 10, 30, or 60 mg/kg; 30 days) led to a robust dose-dependent tumor growth inhibition at 30 mg/kg (44% TGI) and 34% tumor regression when the animals were dosed at 60 mg/kg.Lastly, no body weight loss is observed in any of the mice in this study efficacy models.Animal Model:Nude miceinjected with HEK293 cells
Dosage:3, 10, or 30 mg/kg
Administration:Oral administration
Result:Showed a disruption of the Mcl-1/Bak interaction in this in vivo model.
Animal Model:Nude mice injected with human OPM-2 multiple myeloma tumor cells
Dosage:10, 30, or 60 mg/kg
Administration:Oral administration
Result:Exhibited a inhibition of tumor growth without any toxicity.

体外研究:
Mcl-1 inhibitor 3 shows an IC50 value of 19 nM in an OPM-2 cell viability assay, and a Ki value of 0.061 nM in Mcl-1 HTRF/TR-FRET assay.
