Discovery of N-[(2S)-5-(6-fluoro-3-pyridinyl)-2,3-dihydro-1H-inden-2-yl]-2-propanesulfonamide, a novel clinical AMPA receptor positive modulator.
S.E.Ward, M.Harries, L.Aldegheri, D.Andreotti, S.Ballantine, B.D.Bax, A.J.Harris, A.J.Harker, J.Lund, R.Melarange, A.Mingardi, C.Mookherjee, J.Mosley, M.Neve, B.Oliosi, R.Profeta, K.J.Smith, P.W.Smith, S.Spada, K.M.Thewlis, S.P.Yusaf.
A series of AMPA receptor positive allosteric modulators has been optimized from poorly penetrant leads to identify molecules with excellent preclinical pharmacokinetics and CNS penetration. These discoveries led to 17i, a potent, efficacious CNS penetrant molecule with an excellent pharmacokinetic profile across preclinical species, which is well tolerated and is also orally bioavailable in humans.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
