Titrimetric determination of aminobenzoic acids

Talanta, 1985
A novel titrimetric method for determination of aminobenzoic acids is based on their reaction with excess of bromine to form N-bromo-2,4,6-tribromoaniline, which liberates an equivalent amount of iodine when treated with iodide. The method is applicable to the aminobenzoic acids in the range 0.1-5.0 mg, with a recovery ranging from 96 to 99.7% and a ...

Ribosomal Elongation of Aminobenzoic Acid Derivatives

Journal of the American Chemical Society, 2020
2-Aminobenzoic acid and heterocyclic amino acids are aromatic homologues of β-amino acids, but their chemical properties are quite distinct. Because of the poor nucleophilicity of the amino group conjugated with the aromatic ring, no literature reports of their successful ribosomal elongation in nascent peptide chains have appeared to date.

Photocontact Dermatitis from P-Aminobenzoic Acid

Dermatology, 1978
A 6-year-old girl with xeroderma pigmentosum was contact and photocontact sensitized to PABA which had been used as a sunscreening agent. The activating wavelengths for photocontact dermatitis were in long-wave ultraviolet light. The experimental photocontact sensitization was not induced in guinea pigs. Although PABA is the most effective and harmless

Crystal structure of cyclomaltoheptaose (β-cyclodextrin) complexes with p-aminobenzoic acid and o-aminobenzoic acid

Carbohydrate Research, 2008
Crystal structures of cyclomaltoheptaose (beta-cyclodextrin) complexes with p-aminobenzoic acid and o-aminobenzoic acid have been determined by single-crystal X-ray diffraction. The space group of the beta-cyclodextrin-p-aminobenzoic acid complex is P2(1) with a host:guest stoichiometry of 1:1, and that of the beta-cyclodextrin-o-aminobenzoic acid ...

PARA-AMINOBENZOIC ACID AND INDOLE METABOLISM

Archives of Dermatology, 1948
FOR THE past few years I have in private practice prescribed paraaminobenzoic acid in a variety of dermatoses, including hair and scalp conditions. A surprisingly common subjective response to this therapy has been a feeling of greater vigor, a loss of tired or enervated states. Some patients were so impressed with this result that they sought guidance

Zwitterion ratios of aminobenzoic acids

Australian Journal of Chemistry, 1969
Relations have been established between the pKa values for the non- zwitterionic forms of meta- and para-aminobenzoic acids, pKB, and the pKa values of the corresponding methyl and ethyl esters, pKE. For methyl m-aminobenzoate, the expression is pKB = pKE + 0.09, whilst for the ethyl ester it is pKB = pKE + 0.03.
