compounds for D3receptor (for (−)-40Ki, D3 = 1.84 nM, D2/D3 = 583.2; for (−)-45Ki, D3 = 1.09 nM, D2/D3 = 827.5). Functional data identified (−)-40 (EC50, D2 = 114 nM, D3 = 0.26 nM, D2/D3 = 438) as one of the highest D3selectiveagonists known to date. In addition, high affinity, nonselective D3agonist (−)-19 (EC50, D2 = 2.96 nM and D3 = 1.26 nM) was also developed. Lead compounds with antioxidant activity
