Caspase-3 is an intracellular cysteine protease, activated as part of the apoptotic response to cell injury. Its interest as a therapeutic target has led many to pursue the development of inhibitors. To date, only one series of nonpeptidic inhibitors have been described, and these have limited selectivity within the caspase family. Here we report the(More)
Herein, we describe the discovery of inhibitors of norepinephrine (NET) and dopamine (DAT) transporters with reduced activity relative to serotonin transporters (SERT). Two compounds, 8b and 21a, along with nomifensine were tested in a rodent receptor occupancy study and demonstrated dose-dependent displacement of radiolabeled NET and DAT ligands. These(More)
We synthesized a novel ligand [4,5-3H-Leu9]-Neurokinin A (3H-NKA, S.A 117-144 Ci/mmol), and evaluated its binding to hamster urinary bladder membranes (HUBM). The ligand bound to HUBM in a highly-specific (94 +/- 4%) and protein-dependent manner. Binding was rapid (k1 = 0.037 nM-1*min-1) and saturable (Bmax = 1210 +/- 177 fmol/mg protein), to a single(More)
The peptide corticotropin-releasing factor (CRF) binds to the CRF₁ receptor via a two-domain mechanism such that the extracellular domain (ECD) of the receptor captures the CRF's C-terminus to facilitate the binding of CRF's N-terminus to the juxta-membrane or "J"-site. Known small molecule antagonists bind to the J-site while known CRF₁ receptor peptide(More)
