F. Leroux et al., Phosphodiesterase 4 inhibitors as airways smooth muscle relaxant agents: Synthesis and biological activities of triazine derivatives, BIO MED CH, 7(3), 1999, pp. 509-516
A series of triazine derivatives was synthesized. The compounds were evalua
ted for tracheal smooth muscle relaxant and type 4 phosphodiesterase inhibi
tory activities. A highly significant correlation was observed between the
two effects. Two compounds exhibited potent relaxant activity (EC50: 17 and
24 nM) and might be useful for the treatment of asthma. (C) 1999 Elsevier
