We have developed a series of carbazole-derived compounds based on our hybrid D2/D3 agonist template to design multifunctional compounds for the symptomatic and disease-modifying treatment of Parkinson's disease (PD). The lead molecules (-)-11b (D-636), (-)-15a (D-653), and (-)-15c (D-656) exhibited high affinity for both D2 and D3 receptors and in GTPγS functional assay, the compounds showed potent agonist activity at both D2 and D3 receptors (EC50 (GTPγS); D2 = 48.7 nM, D3 = 0.96 nM for 11b, D2 = 0.87 nM, D3 = 0.23 nM for 15a and D2 = 2.29 nM, D3 = 0.22 nM for 15c). In an animal model of PD, the test compounds exhibited potent in vivo activity in reversing hypolocomotion in reserpinized rats with a long duration of action compared to the reference drug ropinirole. In a cellular antioxidant assay, compounds (-)-11b, (-)-15a, and (-)-15c exhibited potent activity in reducing oxidative stress induced by neurotoxin 6-hydroxydopamine (6-OHDA). Also, in a cell-based PD neuroprotection model, these lead compounds significantly increased cell survival from toxicity of 6-OHDA, thereby producing a neuroprotective effect. Additionally, compounds (-)-11b and (-)-15a inhibited aggregation and reduced toxicity of recombinant alpha synuclein protein in a cell based in vitro assay. These observations suggest that the lead carbazole-based dopamine agonists may be promising multifunctional molecules for a viable symptomatic and disease-modifying therapy of PD and should be further investigated.
Electron transporting and hole blocking organic material and application thereof in thin-film light-emitting diode

Paragraph 0005, (2020/11/02)
The invention provides an electron transporting and hole blocking material with an A-D-A link structure as a core. The material is applied to a thin-film semiconductor light-emitting diode, for example, an organic light-emitting diode and a quantum dot thin-film light-emitting diode; and the molecule of the material takes bipolar carbazole and a derivative group thereof as electron donating centers, so a relatively high triplet state energy level can be maintained to ensure exciton blocking capability.
