Neuroprotectant FK506 inhibits glutamate-induced apoptosis of astrocytes in vitro and in vivo.

abstract：:We have synthesized and characterized a series of novel fluorescently labeled ligands with high affinity and specificity for D1 and D2 dopamine receptors. D1-selective probes were synthesized using (R,S)-5-(4'-aminophenyl)-8-chloro-2,3,4,5-tetrahydro-3-methyl- [1H]-3-benzazepin-7-ol, the 4'-amino derivative of the hig...
