Simple spectrofluorometric determination of p-aminobenzoic and p-aminosalicylic acids in biological fluids by use of terbium-sensitized luminescence.
A novel, sensitive, and selective method has been developed for determination of p-aminobenzoic (PABA) and p-aminosalicylic (PAS) acids in the N-benzoyl-L-tyrosyl-PABA/ PAS test. PAS is measured as a ternary complex with terbium and EDTA (lambda(ex) = 324 nm, lambda(em) = 546 nm) in alkaline aqueous solution (pH approximately 12.6), whereas both compounds (PABA and PAS) are measured as ternary ...
متن کاملDetermination of Methotrexate in Biological Fluids and a Parenteral Injection Using Terbium-Sensitized Method
A new sensitive, simple and rapid method for determination of methotrexate (MTX) was developed based on quenching effects of MTX on the fluorescence intensity of Tb3+-1,10-phenanthroline complex. The fluorescence intensity was measured with excitation wavelength of 300 nm and emission wavelength of 545 nm and the quenched fluorescence intensity is proportional to the concentration of MTX in Tris...

متن کاملMechanism of competitive inhibition of p-aminobenzoic acid oxidation by p-aminosalicylic acid.
The proposed mechanism(s) associated with the inhibition of essential metabolic reactions by various compounds has received a great deal of attention in recent years, since antimetabolites have proved useful in several chemotherapeutic areas and in studying various metabolic reactions. The significance of p-aminobenzoic acid in microbial nutrition was first emphasized when Woods (1940) and Wood...
