Product Description
Description of Nootropics API CAS 51352-87-5
Trimethoprim antibacterial principle is to interfere with bacterial folic acid metabolism. The main mechanism of action is the selective inhibition of bacterial dihydrofolate reductase activity, so that dihydrofolate can not be reduced to tetrahydrofolate, and synthetic folic acid is the main component of nucleic acid biosynthesis, it prevents the bacterial nucleic acid and protein And the binding of mecclidine (TMP) to the bacterial dihydrofolate reductase is 5 to 60,000 fold more tightly bound to the mammalian enzyme.
