  摘要：

  AbstractCarbazoles have attracted high interest among synthetic chemists due to their unique structural features and potential pharmacological activities. Compared to linear aryliodoniums, cyclic diphenyleneiodoniums are more inert and have not attracted much attention to their application as building blocks. Employing our synthetic strategy, diversified carbazoles can be efficiently obtained from a single cyclic diphenyleneiodonium under mild conditions. The reactions catalyzed by copper(II) acetate have provided a variety of carbazoles in modest to good yields with a broad range of amines including anilines, aliphatic amines and sulfonamides. Moreover, one of the obtained carbazoles has displayed an outstanding ability to protect HT‐22 neuronal cells from the damage induced by neurotoxins glutamate and homocysteic acid.magnified image

  this work, a set of structurally diverse synthetic carbazoles was screened for their anticancer activities. According to structure–activity relationship studies, carbazoles with an N-substituted sulfonyl group exhibited better anticancer activity. Moreover, compound 8h was discovered to show the most potent anticancer effects on Capan-2 cells by inducing apoptosis and cell cycle arrest in G2/M phase

  Transition metal-catalyzed diamination by hydroxylamines is a common approach for making three-membered aziridines, while its use for building the larger N-heterocycles is still underdeveloped. Herein, we report an efficient Pd(0)-catalyzed inter-molecular [4+1] annulation of o-bromo(or chloro)-biaryls with bifunctional secondary hydroxylamines for the one-step assembly of synthetically useful carbazoles

• Discovery of novel N-substituted carbazoles as neuroprotective agents with potent anti-oxidative activity

  Carbazole moiety is an important scaffold with a variety of biological applications, for example, anti-oxidative stress. Our previous synthesized carbazoles were screened for their neuroprotective properties against two individual oxidative stresses. Some of the new carbazole derivatives were observed with modest to good neuroprotective effects on neuronal cells HT22 against cell injury induced by glutamate or homocysteic acid (HCA). Substituents introduced to the carbazole ring system play crucial roles in their biological activities. In particular, a bulky group favors the neuroprotective activity of the compounds. One of the new compounds, 6, showed the best neuroprotective effects, which might result from its anti-oxidative activity with a GSH-independent mechanism. These findings might provide an alternative strategy for the development of novel carbazole derivatives for the treatment of CNS diseases such as Alzheimer's disease. (C) 2013 Elsevier Masson SAS.
