MRK-898
MRK-898
MRK-898 is an orally active GABA(A) receptor modulator. MRK-898 binds to α1, α2, α3 or α5 subunit of GABA(A) receptor with Ki values of 1.2 nM, 1.0 nM, 0.73 nM, and 0.50 nM, respectively. However, α1-containing GABA(A) receptors are identified as the "sedative" and α2- and/or α3-containing receptors as the "anxiolytic" subtype(s)[1].
