aminobenzoic acids การใช้

• Sulfadimethoxine inhibits bacterial synthesis of folic acid ( pteroylglutamic acid ) from para-aminobenzoic acid.
• The first researched haptens were aniline and its carboxyl derivatives ( p-aminobenzoic acid ).
• PABA-free : PABA, or para-aminobenzoic acid, is a highly effective sunscreen, once commonly used.
• DHPS is the target of sulphonamides, which are substrate analogues that compete with para-aminobenzoic acid.
• It is also a precursor to 4-aminobenzoic acid.
• The enzyme dihydropteroate synthetase converts pteridine and 4-aminobenzoic acid to dihydrofolic acid in the presence of glutamate.
• "' 3-Nitrobenzoic acid "'is an organic compound with the 3-aminobenzoic acid, which is used to prepare some dyes.
• Pyridoxine, nicotinic acid, p-aminobenzoic acid and biotin are vitamins important for cellulose production whereas pantothenate and riboflavin have opposing effects.
• Biotin, p-aminobenzoic acid and a source of reduced sulfur are required as growth factors in order to cultivate this bacteria.
• Dihydropteroate synthase ( ) ( DHPS ) catalyses the condensation of 6-hydroxymethyl-7, 8-dihydropteridine pyrophosphate to para-aminobenzoic acid to form 7, 8-dihydropteroate.
• Azide has been used traditionally as an MPO inhibitor, but 4-aminobenzoic acid hydrazide ( 4-ABH ) is a more specific inhibitor of MPO.
• The mechanism of action of the molecule is not through the inhibition of chorismate synthase but by the inhibition of 4-aminobenzoic acid synthesis.
• The amount of 4-aminobenzoic acid and its metabolites excreted in the urine is taken as a measure of the chymotrypsin-secreting activity of the pancreas.
• Sulfamethoxazole, a sulfonamide, induces its therapeutic effects by interfering with the " " p "-aminobenzoic acid ( PABA ) in the biosynthesis of dihydrofolate.
• Allergic reactions to the esters is usually due to a sensitivity to their metabolite, para-aminobenzoic acid, and does not result in cross-allergy to amides.
• The emollient salicylic acid is structurally similar to para-aminobenzoic acid ( PABA ), commonly found in sunscreen, and is known to interfere with phototherapy in psoriasis.
• These most often represent an interaction between sun exposure and cosmetics, perfumes, topical medications and even sunscreens, particularly those that contain PABA ( para-aminobenzoic acid ).
• It is an amide derivative of the amino acid glycine and para-aminobenzoic acid that is not naturally found in humans; it needs to be IV infused before use diagnostically.
• The molecular structure of toluenesulfonylamide is similar to para-aminobenzoic acid, an intermediate in bacterial metabolism, which is disrupted by this sulfonamide ( in the same way as by a sulfa drug ).
• Following her work in 1942 with David E . Green on amino-and hydroxy acid oxidases, and on a peptide form of p-aminobenzoic acid, she became interested in new aspects of nitrogen metabolism.
