吡嗪并[2,1-a]异喹啉类似物被我们的小组报道为体外和体内Nrf 2/ARE信号传导的有效激活剂。在这项研究中,我们简化了环系统,以研究吡嗪并[2,1-a]异喹啉支架的各个部分的功能。我们证明了四氢异喹啉不是活性所必需的,吡啶并[1,2-a]吡嗪类似物3b和3g保留了细胞Nrf 2/ARE激活活性。此外,这种简化显著提高了水溶性和膜渗透性,表明这些化合物更有利于进一步开发Nrf 2激活相关的治疗剂。
Pyrazino[2,1-a]isoquinolin analogues were reported as potent activators of Nrf2/ARE signaling both in vitro and in vivo by our group. In this study, we simplified the ring system to investigate the functions of various parts of the pyrazino[2,1-a]isoquinolin scaffold. We proved that the tetrahydroisoquinoline was not essential for activity and the pyrido[1,2-a]pyrazin analogues 3b and 3g retained the cellular Nrf2/ARE activation activity. Besides, this simplification significantly enhanced water solubility and membrane permeability, indicating that these compounds are more favourable for the further development of therapeutic agents around Nrf2 activation.
