title: Choline transport specificity in animal cells and tissues.
abstract: 1. Beta carbolines inhibit choline transport in rat brain. 2. The aziridinium ring on the nitrogen of mustard analogs of choline causes irreversible binding to the carrier in rat brain. 3. The uptake system in rat brain is stereoselective, requires a quaternary nitrogen, and prefers analogs with a nitrogen-oxygen distance of about 3.26 A. 4. In mouse brain troxonium derivatives inhibit choline transport. 5. In cuttlefish optic lobes and torpedo electric organ pyrene derivatives potently inhibit choline transport. 6. In guinea pig placenta, the affinity of the choline carrier remains high even when this molecule lacks one or two methyl groups.
