Sulfonamides and Trimethoprim Targeting the folate biochemical pathway of bacteria. These antibacterial compounds are called folate pathway inhibitors. Sulfonamides interfere with the formation of folic acid, an important precursor for nucleic acid synthesis.

Which of the following antibiotics is a folate synthesis inhibitor?

5.2 Trimethoprim. TMP is a synthetic antibiotic that binds to the enzyme dihydrofolate reductase (DHFR), which inhibits the folate synthesis pathway (Brogden et al., 1982). Widely used in the treatment of urinary tract infections and Pneumocystis jirovecii pneumonia.

Which drug group inhibits folic acid synthesis?

Sulfonamidesa class of antibacterial agents that act by inhibiting folic acid biosynthesis.

What is folic acid synthesis?

Folic acid is Essential nutrients necessary for protein and nucleic acid synthesis (DNA and RNA). Folic acid is synthesized by bacteria from the substrate p-aminobenzoic acid (PABA) and is required for all cell growth. Folic acid (as a vitamin in food) diffuses or is transported into mammalian cells.

Which drugs are classified as folate antagonists?

various drugs such as Gastrointestinal, methotrexate (aminopterin)pyrimethamine, trimethoprim, and triamterene act as folate antagonists, producing folate deficiency by inhibiting this enzyme.

Which of the following is a folic acid antagonist?

Chemical structures of tetrahydrofolate and two antifolates: methotrexate (the classic antifolate) and Sulfacetamide (non-classical antifolate), commonly used as a folate antagonist.

Which antibiotics act as folate antagonists?

Sulfonamides and Trimethoprim Inhibits folate synthesis at two different sites. Sulfonamides are structurally similar to PABA and prevent PABA from binding to dihydropteroic acid. Trimethoprim prevents the reduction of dihydrofolate to tetrahydrofolate by inhibiting the enzyme dihydrofolate reductase.

Is folic acid the same as B12?

Vitamin B12, also known as cobalamin, is found in animal foods such as red meat, fish, poultry, milk, yogurt, and eggs. folic acid (Vitamin B9) refers to the naturally occurring form of the vitamin, while folic acid refers to supplements added to foods and beverages.

Do humans synthesize folic acid?

Unlike plants and bacteria, Humans do not synthesize Vitamin B9 in their bodies. Therefore, they obtain vitamin B9 in the form of folic acid from natural foods or in the form of folic acid (chemically synthesized) from fortified foods.

Which of the following is a folic acid analog?

Folic acid analogs:

The prototype folic acid analog is methotrexate, an inhibitor of dihydrofolate reductase, which catalyzes the conversion of folic acid to tetrahydrofolate. A deficiency of tetrahydrofolate prevents reactions that require the folate coenzyme, thereby disrupting DNA and RNA synthesis.

Is folic acid an antagonist?

What does antibiotic resistance mean?

Antibiotic resistance occurs in Bacteria such as bacteria and fungi have the ability to defeat drugs designed to kill them. This means the bacteria are not killed and continue to grow. Infections caused by antibiotic-resistant bacteria are difficult, sometimes impossible, to treat.
