The discovery of the first class of potent glucose-6-phosphatase catalytic site inhibitors, substituted 4,5,6,7-tetrahydrothieno[3,2-c]- and -[2,3-c]pyridines, is described. Optimisation of this series involved solution phase combinatorial synthesis and very potent compounds were prepared with IC50 values down to 140 nM. The structure activity relationship (SAR) of these compounds indicates that: a tetrahydrothieno[3,2-c]pyridine core ring system and the isomeric [2,3-c] system are equipotent and much better than the corresponding benzo analogue, 1,2,3,4-tetrahydro-isoquinoline. The 4-substituent of the tetrahydrothieno[3,2-c]pyridine ring has to be a phenyl group, optionally substituted with a lipophilic 4-substituent, such as trifluoromethoxy or chloro. The 5-substituent of the tetrahydrothieno[3,2-c]pyridine ring has to be a substituted benzoyl; anisoyl and (E)-3-furan-3-ylacryloyl are the best of the investigated groups. Substitution in the benzoyl ortho position seems to be forbidden, whereas substitution in the meta position is tolerated only if a methoxy para substituent is present. These SAR findings were parallel to those obtained in the 4,5,6,7-tetrahydrothieno[2,3-c]pyridine system. Enantioselectivity in enzyme recognition was observed and the activity resided in all cases only in one of the enantiomers.

Biaryls, 7-naphthyl-5-s-amino-2,3-dihydrobenzo[b]thiophene-4-carbonitriles (3a-e), 8-(1-naphthyl)-6-s-amino-isothiochroman-5-carbonitriles (6a-d), 4-(1-naphthyl)-2-s-aminobezocycloalkene-1-carbonitriles (6e-j), 8-naphthyl-6-s-amino-2-ethyl-1,2,3,4-tetrahydro-isoquinoline-5-carbonitrle (6k-n), 1-naphthyl-3-s-amino-10H-9-thia-phenantherene-4-carbonitriles (8a-e) and 1-(1-naphthyl)-3-s-amino-9,10-dihydrophenantherene-4-carbonitriles (8f-i) have been prepared through carbanion induced ring transformation reactions of 6-naphthyl-3-cyano-4-s-amino-2H-pyran-2-ones (1) from respective ketones (2, 5, and 7). These compounds have been evaluated for their glucose-6-phosphatase inhibitory activity and only 6a, c, j, m, c, d, h displayed significant inhibition of the glucose-6-phosphatase.
