Experiments were conducted in assay tubes containing 0.5 mL sucrose phosphate buffer, 0.5 nM [3H]WIN 35,428 (Kd value = 5.53, specific activity = 84 ci/mmol; Perkin Elmer Life Sciences, Waltham, MA), 1.0 mg of tissue OWW, and various concentrations of inhibitor. activity and drug discrimination paradigms, in mice. A molecular dynamic simulation study supported the hypothesis that atypical DAT inhibitors have similar binding poses at DAT in a conformation that differs from that of cocaine. Such differences may ultimately contribute to their unique behavioral profiles and potential for development as cocaine use disorder therapeutics. +19.54 (MeOH, = 5.2 Hz, 1H), 3.95 (d, = 4.8 Hz, 1H), 3.20 (br s, 1H), 2.70 (s, 1H), 2.35 (dd, = 5.2, 12.4 Hz, 1H), 2.18C1.62 (m, 8H), 1.23 (t, = 7.0 Hz, 3H), 0.84C0.72 (m, 1H), 0.53C0.44 (m, 1H), 0.44C0.34 (m, 1H), 0.12-0.00 (m, 2H); 13C NMR (100 MHz, CDCl3) 172.63, 163.26, 160.82, 138.54, 138.41, 128.40, 128.33, 115.42, 115.20, 80.31, 70.88, 60.44, 60.37, 60.18, 58.05, 51.86, 36.21, 25.87, 24.67, 14.20, 10.29, 4.37, 2.16.
