Abstract:
:4,4-Ditritio-(-)-nicotine (5) of high specific activity (4.7 Ci/mmol) has been synthesized from (-)-nicotine via the readily prepared 4,4-dibromocotinine (3). Scatchard analysis of the binding of 5 to the crude mitochondrial fraction of whole rat brain revealed a Ka of 4.7 X 10(6) M-1 and 13 fmol of binding sites/mg of protein.

杂志文章abstract::A GABA(A) receptor study of several B-nor analogues of allopregnanolone and pregnanolone has been carried out. B-norallopregnanolone (i.e., 3alpha-hydroxy-7-nor-5alpha-pregnan-20-one) was found comparable to allopregnanolone when measured with labeled TBPS. Analogous results were obtained from their effect on neurons ...
