Kev tshawb nrhiav hauv vitro Hauv kev tshuaj ntsuam ntawm cov neeg sib tw neuronal receptors, D-leucine ua tsis tau zoo los sib tw rau kev khi los ntawm cognate ligands, muaj peev xwm hais tawm lub hom phiaj tshiab. Txawm tias thaum noj tshuaj tsawg, D-leucine txo qis kev qaug dab peg tsawg kawg li zoo li diazepam tab sis tsis muaj cov nyhuv sedative. Cov kev tshawb fawb no tsa qhov muaj peev xwm hais tias D-leucine tuaj yeem sawv cev rau chav kawm tshiab ntawm cov tshuaj tiv thaiv qaug dab peg, thiab tias D-leucine yuav muaj qhov tsis paub ua haujlwm yav dhau los hauv eukaryotes.
