WebThe review includes a brief discussion of the inhibition of folate biosynthesis by sulfa drugs. The folate biosynthetic pathway can be divided into two sections. First, the aromatic precursor chorismate is converted to paminobenzoic acid (PABA) by … WebTMP is a synthetic antibiotic that binds with the enzyme dihydrofolate reductase (DHFR) inhibiting the folic acid synthesis pathway ( Brogden et al., 1982 ). It is widely used in the treatment of urinary tract infections and Pneumocystis jiroveci pneumonia.
WebDihydrofolate reductase appears to have two functions in the cell: (1) the synthesis of tetrahydrofolate from the vitamin and (2) participation in the thymidylate synthesis cycle. A very interesting property of dihydrofolate reductases is their extreme sensitivity to folate antagonists containing a 4-amino group. References (73)
