Photoswitchable blockers of potassium channels can be used to opticallycontrol neuronal excitability and hold great promise for vision restoration. Here, we report a series of improved photoswitchable blockers that are furnished with a new pharmacophore based on the local anesthetic bupivacaine. These azobupivacaines (ABs) enable opticalcontrol over the delayed rectifier channel Kv2.1. and target

A method of manufacturing a pipecolamide derivative, characterized in that pipecolic acid or an acid salt thereof is reacted with an amine in an inert solvent in the presence of a condensing agent such as dicyclohexylcarbodiimide, 1-ethyl- 2-(2-dimethylaminopropyl) carbodiimide, methanesulfonyl chloride or phosphoryl chloride. Pipecolamide derivatives, particularly in optically active forms thereof can be efficiently and economically manufactured without harmful gas by-products.

A variety of 2-piperidinecarboxamides were synthesized and evaluated for anticonvulsant activity using the MES and sc PTZ tests in mice and rats. Neurotoxicity was determined by the rotorod test. Several N-(benzyl)-2-piperidinecarboxamides exhibited potent MES activity in mice [2-CF3 14, ED50 = 29 mg/kg; 3-F 16, ED50 = 31 mg/kg; and 3-CF3 17, ED50 = 24 mg/kg]. The most active compounds in the MES test in mice were the 2,6-dimethylanilides [(R,S)-34, ED50 = 5.8 mg/kg; (R)-35, ED50 = 5.7 mg/kg; and (S)-36, ED50 = 14.8 mg/kg]. The enantiomer (S)-36 was about two-fold less potent in the MES test than (R)-35 and also was less neurotoxic. Acylation of the piperidine ring nitrogen of 12 and 34 led to a decrease in the MES activity. In the N-(alpha-methylbenzyl)-2-piperidine-carboxamides, the stereochemistry at either the 2-position of the piperidine ring or at the alpha-position of the N-(alpha-methylbenzyl) group does not significantly affect MES activity.
