Tuberculostatic Derivatives of p-Aminobenzoic Acid. VI. Preparation of Amides of p-Aminosalicylic Acid (PAS) by Means of 2-Acetoxy-4-acetamido-benzoyl Chloride.

Mechanism 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...

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, ...
