Abstract: We investigated the effects of intracerebroventricular administration of NIK-247 (9-amino-2,3,5,6,7,8-hexahydro-1H-cyclo-penta(b)-quinoline monohydrate hydrochloride; a cholinesterase inhibitor) or MKC-231 (2-(2-oxypyrrolidin-1-yl)-N-
(2,3-dimethyl-5,6,7,8-tetrahydrofuro[2,3-b]quinolin-4-yl) acetoamide; a choline uptake enhancer) on plasma glucose level in comparison with that of neostigmine administration in rats. The extents of NIK-247- and MKC-231-induced hyperglycemia were considerably less than that by neostigmine, suggesting that the potencies of the drugs to produce the peripheral hyperglycemia may be pharmacologically negligible.

Keywords: NIK-247, MKC-231, Central hyperglycemia
