Leucomyosuppressin, isolated from head extracts of the cockroach Leucophaea maderae, inhibits evoked transmitter release at the mealworm neuromuscular junction.
TN-871 is a potassium and calcium channel antagonist. TN-871 modulates transmitter release from preganglionic nerve terminals without changing the postsynaptic sensitivity of the ganglion cells to ACh.
CGP 31358 is a new chemical entity with a novel mechanism of action at the NMDA receptor, and as such may form a tool for understanding the molecular pharmacology of this receptor-channel complex. It binds to a site on the NMDA receptor that is coupled to
SKF89976A is a potent GABA uptake inhibitor, which is selective for GAT-1 (IC50 values are 0.13, 550, 944 and 7210 μM for hGAT-1, rGAT-2, hGAT-3 and hBGT-1 respectively). SKF89976A inhibits transport current competitively (Ki = 7 μM) and transmitter-gated current non-competitively (Ki = 0.03 nM). It is able to pass the blood-brain barrier after systemic administration and is active in vivo.
