Expanding the repertoire of small molecule transcriptional activation domains.
Bioorg. Med. Chem. 17 , 1034-43, (2009) Molecules that can reconstitute the function of transcriptional activators hold enormous potential as therapeutic agents and as mechanistic probes. Previously we described an isoxazolidine bearing functional groups similar to natural transcriptional activator... |

Differential modulation of respiratory neuronal discharge patterns by GABA(A) receptor and apamin-sensitive K(+) channel antagonism.
J. Neurophysiol. 86(5) , 2363-73, (2001) The discharge patterns of respiratory neurons of the caudal ventral respiratory group (cVRG) appear to be subject to potent GABAergic gain modulation. Local application of the GABA(A) receptor antagonist bicuculline methochloride amplifies the underlying disc... |
