본 발명은 DMP(dimethylphenyl) 리간드 기반의 이리듐 화합물을 높은 수율과 우수한 공정 효율로 합성이 가능한 합성방법으로서, (ⅰ) 마이크로 웨이브 반응기를 활용하고, (ⅱ) 반응과정 중 "이리듐" 이합체 구조를 사용하여 종래 알려진 수율 대비 현저히 향상된 수율을 거둘 수 있는 합성방법에 관한 것이다.
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
