Comprehensive structure activity relationship (SAR) studies were conducted on a focused screening hit, 2-(methylthio)-3-(phenylsulfonyl)-4H-pyrido[1,2-a]pyrimidin-4-imine (1, IC50: 4.0 nM), as 5-HT6 selective antagonists. Activity was improved some 2-4 fold when small, electron-donating groups were added to the central core as observed in 19, 20 and 26. Molecular docking of key compounds in a homology model of the human 5-HT6 receptor was used to rationalize our structure-activity relationship (SAR) findings. In pharmacokinetic experiments, compound 1 displayed good brain uptake in rats following intra-peritoneal administration, but limited oral bioavailability. (C) 2014 Elsevier Ltd. All rights reserved.

The invention relates to methods and products for modulating glycosylation of proteins. The invention is useful for identifying therapeutic compounds to treat glycosylation-associated disorders such as neurodegeneration, diabetes, including complications of diabetes such as insulin resistance, nephropathy, microvascular damage, and endothelial dysfunction. The invention is also useful for identifying therapeutic compounds to treat de-glycosylation-associated disorders such as ischemic damage and traumatic injury. The invention also relates in part to assays that are useful for identifying and testing candidate compounds for modulating glycosylation of proteins and also relates in part to compounds to treat glycosylation-associated diseases and disorders.
