Recent investigations have shown that distillers’ dried solubles contain a factor or factors which are necessary for the growth of chicks (1) and rats (2). This factor is distinct from vitamin A, vitamin D, thiamine, riboflavin, inositol, nicotinic acid, pantothenic acid, p-aminobenzoic acid, choline, pyridoxine, biotin, folic acid, or 2-methylnaphthoquinone. A procedure has been developed for ...

Nowadays, 2-ethylhexyl 4-(N,N-dimethylamino)benzoate (EDP) is one of the most widely used UV filters in sunscreen cosmetics and other cosmetic products. However, undesirable processes such as percutaneous absorption and biological activity have been attributed to this compound. The in vitro metabolism of EDP was elucidated in the present work. First of all, the phase I biotransformation was stu...

A twoplex method using (12)C6 and (13)C6 stable isotope analogues (Δmass = 6 Da) of 2-aminobenzoic acid (2-AA) is described for quantitative analysis of N-glycans present on monoclonal antibodies and other glycoproteins using ultra performance liquid chromatography with sequential fluorescence and accurate mass tandem quadrupole time of flight (QToF) mass spectrometric detection.

Analytical recovery of urinary p-aminobenzoic acid liberated from bentiromide(N-benzoyl-L-tyrosyl-p-aminobenzoicacid) was determinedby roomtemperaturephosphorimetryas an index to exocrine pancreatic function. Metabolites were hydrolyzed to the parent compound in 4 mol/L NaOH, then quantified, after pH adjustment, by spothng 3 L of this solution onto filter paper treated with potassium iodide an...

Meta-aminobenzoic acid, an important model system in the study of polymorphism and crystallization of active pharmaceutical ingredients, exist in water in both the nonionic (mABA) and zwitterionic (mABA±) forms. However, the constituent molecules of the polymorph that crystallizes from aqueous solutions are zwitterionic. This study reports atomistic simulations of the events surrounding the ear...

aminocarboxylic acids, such as 2-aminobenzoic acid, react easily with [ir(cod)(pme3)3]cl, (cod=1,5-cyclooctadiene), in thf to produce hydridoaminocarboxylato iridium(iii) complexes in high yields. these octahedral complexes are formed via oxidative addition reaction of the o-h bond of the carboxylic group with the central metal. the starting iridium(i) complex losses the cod molecule, the chlor...
