E4837 Trimethoprim (lactate) Trimethoprim (lactate) is an antifolate antibacterial agent that inhibits bacterial dihydrofolate reductase (DHFR), an essential enzyme responsible for the production of tetrahydrofolic acid (THF). By blocking this enzyme, it prevents the synthesis of bacterial DNA, hindering bacterial survival. This compound is a standard antibiotic for treating urinary tract infections (UTIs).
S5200 Diaveridine Diaveridine (AI3-23935, CCRIS-3784) is a coccidiostat with anti-parasitic activity and also a dihydrofolate reductase (DHFR) inhibitor preventing folic acid synthesis in species of Pneumocystis.
S5136 Calcium folinate (Leucovorin calcium) Calcium folinate (Leucovorin calcium) is a metabolically active, reduced form of folic acid that is rapidly absorbed and extensively metabolized in the liver to other folic acid derivatives.Solutions are unstable and should be fresh-prepared.
S1210 Methotrexate Methotrexate, analog of folic acid, is a nonspecific inhibitor of the dihydrofolate reductase(DHFR) of bacteria and cancerous cells as well as normal cells. It forms an inactive ternary complex with DHFR and NADPH. Methotrexate (MTX) induces apoptosis.
