However,It Is A Relatively Weak Inhibitor With An Ic50,Of 9 Mu M And Is Subject To Oxidation Via Cyclooxygenase,Limiting Its Therapeutic Value. In This Paper We Describe The Synthesis And Testing Of A Novel Series Of Monounsaturated C18 And C16 Acyl-Glycine Molecules As Inhibitors Of The Glycine Transporter Giyt2. We Demonstrate That They Are Up To 28 Fold More Potent That N-Arachidonyl-Glycine With No Activity At The Closely Related Glyt1 Transporter At Concentrations Up To 30 Mu M. This Novel Class Of Compounds Show Considerable Promise As A First Generation Of Giyt2 Transport Inhibitors. Doi:10.1021/acschemneuro.7B00105
