Dual-acting hybrid anti-oxidant/anti-inflammatory agents were developed employing the principle of pharmacophore hybridization. Hybrid agents were synthesized by combining stable anti-oxidant nitroxides with conventional non-steroidal anti-inflammatory drugs (NSAIDs). Several of the hybrid nitroxide-NSAID conjugates displayed promising anti-oxidant and anti-inflammatory effects on two Non-Small Cell
This invention relates to compositions for preventing or reducing the degradation of elastin and other proteins and thereby preventing or retarding the disease states caused by said degradation containing as active ingredients compounds, some of which are novel, of the formula:
or their pharmacologically acceptable salts.
Starting from methyl 5-nitrosalicylate (20) the N- and O-beta-glucopyranosyl derivatives (24, 28) of 5-aminosalicylic acid were prepared. The LD50 values of these compounds were determined on mice, and the inhibitory effect of 24 (0.83 mmol/kg) and 28 (1.2 mmol/kg) on gastric ulcer on rats, induced by indomethacin was investigated.
