Trans-gamma-hydroxycrotonic acid binding sites in brain: evidence for a subpopulation of gamma-hydroxybutyrate sites.


Trans-gamma-hydroxycrotonate (THCA), a compound naturally present in rat brain, possesses high-affinity binding sites with a heterogeneous distribution which are superimposable with those for gamma-hydroxybutyrate (GHB). Binding studies of THCA on rat brain membranes revealed two binding components, one of high affinity (Kd1, 7 nM, Bmax1 42 fmol/mg protein… (More)
