Development of ketoprofen-p-aminobenzoic acid co-crystal: formulation, characterization, optimization, and evaluation

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, ...

Synthesis, Crystal Structure and Biological Activity of 2-Hydroxyethylammonium Salt of p-Aminobenzoic Acid

p-Aminobenzoic acid (pABA) plays important roles in a wide variety of metabolic processes. Herein we report the synthesis, theoretical calculations, crystallographic investigation, and in vitro determination of the biological activity and phytotoxicity of the pABA salt, 2-hydroxyethylammonium p-aminobenzoate (HEA-pABA). The ability of neutral and anionic forms of pABA to interact with TIR1 pock...

Rapamycin-Loaded, CapryolTM 90 and Oleic Acid Mediated Nanoemulsions: Formulation Development, Characterization and Toxicity Assessment

This study was planned to explore the capability of nanoemulsions (NEs) consisting of CapryolTM 90 and oleic acid for the delivery of rapamycin (RAP). Permeability and cytotoxicity of RAP-loaded NEs were also inspected. Pseudo-ternary phase diagrams were created with oleic acid and CapryolTM 90 (as oil phase) and four surfactants and co-surfactants at various weight ratios (Rsm). Selected NEs f...
