Another compound 113 RS-37619, () 5-benzoyl-1,2-dihydro- 3H-pyrrolo[1,2-a] pyrrole-1-carboxylic acid has been also reported to possess potent analgesic and anti-inflammatory activity. Aromatic compounds are less reactive than alkenes, making them useful industrial solvents for nonpolar compounds. Bicyclic Compounds / 17 2.7 . . Aromatic Acids: These compounds are represented by the general formula, R-COOH, where R may be H, alkyl, or aryl group.Their molecular structure is characterized by the presence of at least one carboxyl (-COOH) group C n H 2n+1 COOH.. Traditional medications contain numerous ingredients that can trigger allergic reactions or sensitivities. These compounds are called aromatic compounds due to their special type of smell. 4-6, 8, 12, 13 While this previous work has used pK a values to classify each compound, 4-6, 8, 12, 13 the focus was on the nature of compounds at physiological pH. Key aromatic hydrocarbons of commercial interest are benzene, toluene, ortho-xylene and para-xylene They are extracted from complex mixtures obtained by the refining of oil or by distillation of coal tar, and are used to produce a range of important chemicals and polymers, including styrene, phenol . or the pharmaceutically acceptable salts can be applied to modulate the in-vitro and in-vivo binding processes mediated by E-, P- or L-selectin binding. 1 It is a measure of water in a substance that is available to react with or attach itself to a material, and it ranges from 0.03-1.0.
