Description

Pyrimethamine is a white crystalline powder; odorless and tasteless. It is slightly soluble in ethanol or chloroform and almost insoluble in water.

Pyrimethamine can inhibit the dihydrofolate reductase of Plasmodium vivax, thus interfering with the normal folic acid substitution of Plasmodium vivax, which is effective against Plasmodium falciparum and Plasmodium falciparum pre-erythrocytic stage, and is often used as etiological prophylaxis. In addition, it can also inhibit the development of Plasmodium in mosquitoes, so it can interrupt transmission. It is used clinically for malaria prophylaxis and anti-relapse treatment in the resting phase.

ECHEMI Editorial Reference

Pyrimethamine(RP4753) is a medication used for protozoal infections; interferes with tetrahydrofolic acid synthesis from folic acid by inhibiting the enzyme dihydrofolate reductase (DHFR).IC50 Value: 15.4 nM (Plasmodium falciparum) [1]Target: DHFR; antifolatein vitro: Three susceptibility levels (susceptible, intermediate, and resistant) were observed in the response of culture-adapted clones and strains to pyrimethamine (50% inhibitory concentration [IC50]) < 100, 100-2,000, and > 2,000

Pyrimethamine is an odorless white crystalline powder. Tasteless. An antimalarial drug.|Pyrimethamine is an aminopyrimidine that is pyrimidine-2,4-diamine which is substituted at position 5 by a p-chlorophenyl group and at position 6 by an ethyl group. It is a folic acid antagonist used as an antimalarial or with a sulfonamide to treat toxoplasmosis. It has a role as an antimalarial, an EC 1.5.1.3 (dihydrofolate reductase) inhibitor and an antiprotozoal drug. It is an aminopyrimidine and a member of monochlorobenzenes.|One of the folic acid antagonists that is used as an antimalarial or with a sulfonamide to treat toxoplasmosis.|Pyrimethamine is a Dihydrofolate Reductase Inhibitor Antimalarial. The mechanism of action of pyrimethamine is as a Dihydrofolate Reductase Inhibitor.|Pyrimethamine is a synthetic derivative of ethyl-pyrimidine with potent antimalarial properties. Pyrimethamine is a competitive inhibitor of dihydrofolate reductase (DHFR). DHFR is a key enzyme in the redox cycle for production of tetrahydrofolate, a cofactor that is required for the synthesis of DNA and proteins. This agent is often used in combination with other antimalarials for the treatment of uncomplicated falciparum malaria. (NCI04)|One of the FOLIC ACID ANTAGONISTS that is used as an antimalarial or with a sulfonamide to treat toxoplasmosis.
