In this study the effects of compound B1, bis(3-aryl-3-oxo-propyl)methylamine hydrochloride, and an anti-inflammatory drug, indomethacin, were tested by carrageenan-induced paw edema and cotton pellet granuloma tests, for effects on acute and chronic phases of inflammation, respectively. Their effects on vascular permeability were also determined by hyaluronidase-induced capillary permeability test. Anti-inflammatory activity of B1 was compared with indomethacin. B1 decreased the carrageenan-induced paw edema by 49%, 35%, and 47% at 50, 100, and 200mg kg^<-1> doses, respectively, while this decrease was 82% by indomethacin at 20mg kg^<-1> dose. Antiproliferative effects in cotton pellet test of B1 at 50mg kg^<-1> and indomethacin at 20mg kg^<-1> doses were 44% and 43%, respectively. Indomethacin but not B1 inhibited the hyaluronidase-induced increase in capillary permeability. Our results suggest that B1 inhibits both acute and chronic phases of inflammation probably by an effect not mediated by prevention of increased capillary permeability. Especially, its anti-inflammatory activity against chronic phase of inflammation was comparable with that of indomethacin. Further detailed studies are needed to clarify the mechanism(s) of action responsible for the anti-inflammatory activity of B1.
