Pharmacological studies of furo [3,2-b] indole derivatives. I. Analgesic, anti-pyretic and anti-inflammatory effects of FI-302, N-(3-piperidinopropyl)-4-methyl-6-trifluoromethyl-furo [3,2-b]indole-2-carboxamide, in experimental animals.
The analgesic, anti-pyretic and anti-inflammatory effects of FI-302, N-(3-piperidinopropyl)-4-methyl-6-trifluoromethyl-furo [3,2-b]indole-2-carboxamide, a newly synthesized tricyclic compound, were investigated in comparison with those of nonsteroidal anti-inflammatory drugs (NSAIDs). FI-302 showed potent analgesic and antipyretic effects in the various models used. FI-302 showed an inhibitory effect on acute inflammatory response such as carrageenin-induced edema, but did not show any effect on chronic inflammatory response such as cotton pellet granuloma. These effects of FI-302 were about 2 to 7 times more potent than those of non-acidic NSAIDs such as mepirizole and tiaramide. Moreover, FI-302 had little or no ulcerogenic activity. From these results, it is conceivable that the spectrum of FI-302's activities is similar to those of non-acidic NSAIDs such as mepirizole and tiaramide. These results suggest that FI-302 is a new non-ulcerogenic anti-inflammatory compound, and should be suitably applicable for clinical purposes.
