Separation of p-Aminobenzoic Acid Derivatives
According to the literature, p-aminobenzoic acid (PAB) is excreted in the urine mostly as the free acid and its N-acetyl derivative; the remaining part is eliminated conjugated with glucuronic acid and as p-aminohippuric acid (PAH) (Ellinger & Hensel, 1914'; Hensel, 1914; Cohen & McGilvery, 1946; Salassa, Bollman & Dry, 1948). There is no agreement concerning the formation of PAH. Thus, Beyer, ...
متن کاملDiazotization of Aniline Derivatives and Diazo Couplings in the Presence of p-Toluenesulfonic Acid by Grinding
The solid–solid reactions of electron-donor compounds, such as: barbituric acid (1a), thiobarbituric acid (1b), 1,3-dimethyl barbituric acid (1c), phenol (1d) and resorcinol (1e) with diazotized o-nitroaniline (3), m-nitroaniline (4) and p-nitroaniline (5) catalyzed by p-toluenesulfonic acid (2) afford azo dyes by grinding in good yields. This new method totally avoids the use of inorganic acid...
متن کاملSynthesis of palmitic acid derivatives of p-aminophenol and p-amino benzoic acid with improved pharmacodynamic profiles
In the present study, p-amino phenol (PAP) and p-amino benzoic acid (PABA) have been modified as lipids palmitoyl p-amino phenol (PPAP) and palmitoyl N p-amino benzoic acid (N-PPABA) by a simple amide formation reaction of the respective compounds with palmitoyl chloride. On screening PPAP and N-PPABA for pharmacological activity, PPAP (an analogue of paracetamol) has been found to exhibit pote...
متن کاملThe synthesis and biological evaluation of mycobacterial p-hydroxybenzoic acid derivatives (p-HBADs).
Mycobacterium tuberculosis establishes chronic infection and causes disease through manipulation of the host's innate and adaptive immune response. The bacterial cell wall is highly complex and contains a rich variety of glycosylated compounds that are secreted during infection and have been proposed as immunomodulatory molecules. Amongst the most important of these are the p-hydroxybenzoic aci...
متن کاملDerivatives of Glucuronic Acid
The presence of glucuronic acid in the complex molecules of specific bacterial polysaccharides (1) has stimulated a study of certain derivatives of this important substance and its lactone, glucuron. These investigations have entailed the necessity of elaborating a satisfactory method for preparing both the acid and its lactone, and at the same time they have embraced a study of the comparative...
