Bioactivity | MF-766 is a highly potent, selective and orally active EP4 antagonist with a Ki of 0.23 nM. MF-766 behaves as a full antagonist with an IC50 of 1.4 nM (shifted to 1.8 nM in the presence of 10% HS) in the functional assay. MF-766 can be used for cancer and inflammation diseases research[1][2]. | ||||||||||||
Invitro | MF-766 (0.01-10 μM; pretreatment for 1 h and then stimulated with 50 ng/mL IL-2; with and without 0.33 μM PGE2; 18 hours) reverses PGE2-suppressed IFN-γ secretion in human NK cells. Additionally, NK cell viability is not affected by MF-766[2]. | ||||||||||||
In Vivo | MF-766 (oral gavage; 30 mg/kg; once daily; 21 days) exhibits TGI% of 49% in CT26 tumor model. But it does not exhibits significant difference in EMT6 and 4T1 tumor model[2].MF-766 (oral gavage; 30 mg/kg combination with anti-PD-1 mDX400; once daily; 21 days; q4dx8) shows potent anti-tumor activities in different preclinical models. The % of TGI are 89%, 66% and 40%, respectively in CT26 tumor, EMT6 and 4T1 tumor model[2]. Animal Model: | ||||||||||||
