Choline acetyltransferase inhibitor

WebAcetylcholine is a transmitter for some presynaptic neurons and/or amacrine cells in retina. Selective inhibitors of choline acetyltransferase and carnitine acetyltransferase were used in the evaluation of choline acetyltransferase and carnitine acetyltransferase activities in the rat retina. WebNine styrylpyridine analogs were tested as inhibitors of choline acetyltransferase which had been highly purified from rat cerebrum and bovine caudate nuclei. In general, concentrations required to achieve 50% inhibiion (I50 values) were in the micromolar range. For some analogs, I50 values were similar to those obtained previously by other …
