Nonsteroidal antiinflammatory agents. 2. Derivatives/analogues of dibenz[b,e]oxepin-3-acetic acid
Abstract:
6,11-Dhydro-11-oxodibenz[b,e]oxepins and some related compounds have been synthesized and evaluated for antiinflammatory effect according to the carrageenan paw edema method in rats. The structure-activity relationships have been discussed among acetic acid, carboxylic acid, alcohol, and tetrazole derivatives of dibenzoxepins and acetic acid derivatives of thienobenzoxepins and of the corresponding thiepins. The 3-isopropyl alcohol 9 and 11-deoxo-3-propionic acid (49) were more active than indomethacin but not as active as the title compound (i.e., 43). Carboxylic acids, tetrazoles, esters, amides, and ketones were less active than the corresponding acetic acids. Three compounds (31, 33, and 34) were evaluated for ulcerogenicity and lethality but none surpassed 6,11-dihydro-11-oxodibenz[b,e]oxepin-3-acetic acid (41) in therapeutic ratio.

The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
