Vascular adhesion protein-1 (VAP-1), an amine oxidase that is also known as a semicarbazide-sensitive amine oxidase (SSAO), is present in particularly high levels in human plasma, and is considered a potential therapeutic target for various inflammatory diseases, including diabetes complications such as macular edema. In our VAP-1 inhibitor program, structural modifications following high-throughput screening (HTS) of our compound library resulted in the discovery that thiazole derivative 10, which includes a guanidine group, shows potent human VAP-1 inhibitory activity (IC50 of 230 nM; rat IC 50 of 14 nM). Moreover, compound 10 exhibited significant inhibitory effects on ocular permeability in STZ-induced diabetic rats.

A number of N-[4-[4-(1H-indol-3-yl)piperidinoalkyl]-2- thiazolyl]alkanesulfonamides (8-21) were synthesized and evaluated for their preventive effects on systemic anaphylaxis in guinea pigs. Structure-activity analysis revealed that methane- and ethanesulfonamide derivatives having a one to three methylene tether between the piperidine and thiazole rings exhibited potent activity but the introduction of a substituent on the indole part reduced the activity. Administration (100 mg/kg p.o.) of the four compounds 8, 9, 12, 13, together with ketotifen, oxatomide, terfenadine and azelastine as reference compounds, to mice revealed that only compound 8 caused no significant increase of the sleeping time induced by hexobarbital. In addition, compound 8 (10 mg/kg i.v.) did not change the electroencephalogram in conscious rabbits. These results led to the selection of N-[4-[4-(1H-indol-3-yl)piperidinomethyl]-2-thiazolyl]methanesulfonamide (8, FK613) for further development as a novel antiallergic agent. Clinical evaluation of FK613 is now in progress.
