  Tranilast (TL) oily gels containing UV-absorbing agents (UV absorber) were prepared, and the effect of the agents against photodegradation of TL was investigated. When 0.1% TL oily gel without UV absorber was exposed to light, TL was photochemically decomposed to the extent of 74.1% of its initial content at the end of the first hour. Although there were differences in the preventive effect on photodegradation of TL depending on the UV absorbers employed, 2-(2-benzotriazolyl)-p-cresol (BTPC) was the most effective absorber. The addition of UV absorbers to the oily gel did not affect the release of TL from the gel, the skin permeation, or the skin concentration of TL following topical application. UV absorbers added to TL oily gel penetrated into skin; however, their concentration in skin was similar to that following application of commercial sunscreen. These results suggest that the addition of UV absorbers to the oily gel of TL may be useful in preventing photodegradation of TL in the gel.

  We found that N-(trans-3, 4-dimethoxycinnamoyl) anthranilic acid (tranilast) is readily transformed by photo-irradiation to N-(cis-3, 4-dimethoxycinnamoyl) anthranilic acid (cis-isomer) and a cyclobutane derivative (dimer). Of these photo-irradiated products of tranilast, the cis-isomer was found to inhibit hyaluronidase more effectively than tranilast. From these results, it wsa expected that the cis-isomer might have more effective anti-allergic activity than tranilast ; indeed, the cis-isomer was found to show more effective prevention than tranilast of (1) histamine release from sensitized rat peritoneal mast cells induced by antigen (egg white albumin), (2) histamine release from rat peritoneal mast cells induced by concanavalin A and calcium ionophore A-23187, and (3) the 48 h homologous passive cutaneous anaphylaxis (PCA) in rats.
