TEAC antioxidant activity of 4-hydroxybenzoates

Free Radical Biology and Medicine, 1999
The influence of pH, intrinsic electron donating capacity, and intrinsic hydrogen atom donating capacity on the antioxidant potential of series of hydroxy and fluorine substituted 4-hydroxybenzoates was investigated experimentally and also on the basis of computer calculations.

Interaction of 3-Hydroxybenzoate with 3-Hydroxybenzoate-6-hydroxylase

Biotechnology Progress, 2001
The gradual quenching of the emission fluorescence of 3-HBA in the visible region upon titration with 3-HBA-6-hydroxylase and distinct changes in the near-UV circular dichroic spectrum of the enzyme in the presence of substrate suggest the formation of a stable enzyme-substrate complex.

Excited-state proton transfer of 3-hydroxybenzoic acid and 4-hydroxybenzoic acid

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2010
The excited-state proton transfer of 3-hydroxybenzoic acid and 4-hydroxybenzoic acid was studied by time-resolved laser-induced fluorescence spectroscopy with ultra-short laser pulses. The excited-state reactions were identified in aqueous media as a function of the pH value.

Metabolism of 1-hydroxybenzo[a]pyrene

Chemico-Biological Interactions, 1981
Abstract A metabolite of the known carcinogen benzo[ a ]pyrene (BP), 1-hydroxybenzo[ a ]pyrene 1-BPOH, is further metabolized by rat liver homogenate and microsomes. This oxidation is shown to be enzyme-catalyzed and dependent upon the presence of NADH and NADPH. Isolation of the final product yielded the BP-1,6-dione.

Polyesters of hydroxybenzoic acids

Journal of Applied Polymer Science, 1959
Polymers and copolymers were prepared from the acetoxy derivatives of m- and p-hydroxybenzoic acids. Molecular weights of over 20,000 were obtained for poly(m-hydroxybenzoic acid) and copolymers containing up to 60% para isomer. These polyesters were crystalline, and the degree of crystallinity increased as the para isomer content was increased. Blocks

Action of Methyl Hydroxybenzoate on Nervous Conduction

Nature, 1961
METHYL hydroxybenzoate and its sodium derivative are recommended by the B.P.C. and by Martin-dale1 as preservatives for creams, emulsions, lotions and ophthalmic solutions, and they are used to preserve local anaesthetics. During an investigation of the action of phenol on nerve fibres2,3, we examined the action of methyl hydroxybenzoate and its sodium
