生物活性：
M3258 is an orally bioavailable, potent, reversible and highly selective immunoproteasome subunit LMP7 (β5i) inhibitor. M3258 exerts high biochemical (IC50=3.6 nM) and cellular (IC50=3.4 nM) potency against the LMP7 subunit. M3258 shows strong antitumor efficacy in multiple myeloma xenograft models. M3258 leads to a significant and prolonged suppression of tumor LMP7 activity and ubiquitinated protein turnover and the induction of apoptosis in multiple myeloma cells.
体内研究：
M3258 (1 mg/kg; 10 mg/kg) shows superior antitumor efficacy in selected multiple myeloma and mantle cell lymphoma xenograft models compared with the approved nonselective proteasome inhibitors bortezomib and ixazomib.Animal Model:Female H2d Rag2 mice or female CB-17 SCID mice (U266B1 subcutaneous xenograft model; MM.1S subcutaneous xenograft model)
Dosage:1 mg/kg in U266B1 subcutaneous xenograft model; 10 mg/kg in MM.1S subcutaneous xenograft model
Administration:P.o.; either once daily, every 2 days or twice weekly (days 1 and 4)
Result:Displayed significant and strong antitumor efficacy.
体外研究：
M3258 inhibits human LMP7 with a mean IC50 of 4.1 nM. M3258 displays weak activity against the constitutive proteasome subunit β5 (mean IC50=2519 nM). M3258 potently inhibits LMP7 in the human multiple myeloma cell lines MM.1S and U266B1 and in human, rat, and dog PBMCs with IC50s between 2 and 37 nM.M3258 induces a >four fold accumulation of ubiquitinated proteins with an EC50 of 1980 nM in MM.1S cells. M3258 interferes with immunoproteasome function. M3258 also induces apoptosis assessed by caspase 3/7 activity (EC50=420 nM;>3.5-fold induction) and reduces MM.1S cell viability (IC50=367 nM).
