MECHANISM OF ACTION
Biocure2mg injection used in mammalian cells is a reversible inhibitor of the chymotrypsin-like activity of the 26-S proteasome. The drug prohibits targeted proteolysis that affects multiple signaling cascades responsible for normal homeostatic functions within the cell, leading to cell death.
The peak plasma concentration after 1st dose is 57 and 112ng/mL, If administrated two times a week, Cmax observed for 1mg/m2dose is 67 to 106ng/mL, for 1.3mg/m2 is 89 to 720ng/mL.
human serum plasma concentration is >80%
Biocure2mg injection metabolized mainly through cytochrome P450 isoenzymes CYP3A4, CYP2C19 & CYP1A2.
The excretion pathways of Biocure2mg have not been characterized. The terminal elimination of half life after the 1mg/m2 dose is 40hrs - 193hrs, after dose 1.3mg/m2 is 76hrs - 108hrs.
