Identification and optimization of novel partial agonists of neuromedin B receptor using parallel synthesis.

abstract：:The blood-brain barrier choline transporter may have utility as a drug delivery vector to the central nervous system. Surprisingly, this transporter has as yet not been cloned and expressed. We therefore initiated a 3D-QSAR study to develop predictive models for compound binding and identify structural features import...
