在无金属和无碱条件下,采用原子经济策略,由菲啶-6-胺和醛经硫代环氧化环化反应合成了一系列咪唑并[1,2- f ]菲啶衍生物。在所有合成的衍生物中,化合物3d和3f的IC 50值分别为2.18±0.08和2.24μM±0.71μM。化合物3d对HT-29细胞具有最强的抑制活性,IC 50值为1.25μM±0.22μM,甚至比紫杉醇更强。
Series of 6-aminophenanthridines and related heterocyclic compounds such as benzonaphtyridines were prepared. Reduction of one of the three aromatic rings was also performed. The compounds were first tested for their antiprionactivity in a previously described yeast-based colourimetric prion assay. The most potentderivatives were then assayed ex vivo against the mammalian prion PrPSc in a cell-based
A series of imidazo[1,2-f]phenanthridinederivatives were synthesized from phenanthridin-6-amine and aldehydes through sulfur endorsed oxidative cyclization reaction under a metal- and base-free condition with atom economy strategy and evaluated their anticancer activity. Among all the synthesized derivatives, the compound 3d and 3f exhibited IC50 values of 2.18 ± 0.08 and 2.24 μM ± 0.71 μM, respectively
