TPMPA
Based on 1 publication(s) in Google Scholar
TPMPA, a hybrid of isoguvacine and 3-APMPA, is the first selective antagonist for a GABAC receptor (KB = 2.1 μM), but not to interact with GABAA (KB = 320 μM) or GABAB receptors (EC50 = 500 μM). TPMPA has the potential for the research of suppressing orientation selectivity in ganglion cells.

TPMPA antagonizes the GABA currents of ρ1 receptors (IC50 = 1.6 μM) and those of the chimeric ρ1/α1 receptors with approximately the same potency (IC50 = 1.3 μM)[1].
TPMPA shows weak activity against rho-1 and rho-2 receptors, with the KB values of 2.0 and 15.6 μM, respectively[2]
