In the current work, sixteen novel amide derivatives of phenanthridine were designed and synthesized using 9-fluorenone, 4-Methoxy benzyl amine, and alkyl/aryl acids. The characterization of the title compounds was performed using LCMS, elemental analysis, 1HNMR, 13CNMR and single crystal XRD pattern was also developed for compounds A8. All the final analogs were screened in vitro for anti-leishmanial activity against promastigote form of L. infantum strain. Among the tested analogs, four compounds (A-06, A-11, A-12, and A-15) exhibited significant anti-leishmanial activity with EC50 value ranges from 8.9 to 21.96 μM against amastigote forms of tested L. infantum strain with SI ranges of 1.0 to 4.3. From the activity results it was found that A-11 was the most active compound in both promastigote and amastigotes forms with EC50 values 8.53 and 8.90 μM respectively. In-silico ADME prediction studies depicted that the titled compounds obeyed Lipinski's rule of five as that of the approved marketed drugs. The predicted in-silico toxicity profile also confirmed that the tested compounds were non-toxic. Finally, molecular docking and molecular dynamics study was also performed for significantly active compound (A-11) in order to study it's putative binding pattern at the active site of the selected leishmanial trypanothione reductase target as well as to understand the stability pattern of target-ligand complex for 100 ns. Single crystal XRD of compound A-08 revealed that the compound crystallizes in monoclinic C2/c space group and showed interesting packing arrangements.

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 antiprion activity in a previously described yeast-based colourimetric prion assay. The most potent derivatives were then assayed ex vivo against the mammalian prion PrPSc in a cell-based assay. Several of the new compounds were found more potent than the parent lead 6-aminophenanthridine. The most promising compounds against yeast and mammalian prions were 8-azido-6-aminophenanthridine (3m), and 7,10-dihydrophenanthridin-6-amine (14). In the mammalian cell-based assay, the IC50 of these two compounds were around 5 μM and 1.8 μM, respectively.

A robust route to a diverse set of 6-aminophenanthridines via palladium-catalyzed C-H activation of N-sulfonyl-2-aminobiaryl and isocyanide insertion is reported. This transformation could also provide an important approach for building core frameworks of conjugated organic polymer materials.

Object of the present invention is to provide an organic electroluminescent element having an emissive layer that may be formed by wet process in the fabrication of the organic electroluminescence device with multi-layer structure and has excellent electron-injection property, electron-transfer property, durability and luminescent efficiency and a novel alcohol-soluble organic phosphorescent material that may be preferably applicable to the fabrication of the same. An organic electroluminescent element 1 has a plurality of laminated organic layers 4, 5, 6 sandwiched between anode 3 and cathode 7. A hole transport layer 5 composed of organic compounds insoluble in alcohol solvent and an emissive layer 6 formed by a wet process so that it contacts with the hole transport layer 5 on the side facing with the cathode 7 contains host materials consisting of one or more phosphine oxide derivatives soluble in alcohol solvent and guest materials soluble in alcohol solvent which can be excited electrically to emit light.

A simple synthesis of biologically active 6-aminophenanthridines was achieved by a Suzuki-Miyaura coupling reaction. Condensation of 2-(4,4,5,5-tetramethyl-1,3-dioxaborolan-2-yl)aniline with 2-chlorobenzonitriles afforded 6-aminophenanthridines useful as prions inhibitors in a mild one-step procedure. The intermediate 2-amino-2′cyanobiphenyls could not be isolated.

Biologically active 6-aminophenanthridines were prepared in a single step procedure: Metal amides in liquid ammonia promoted the condensation of anilines with 2-chloro-benzonitriles. 6-Aminophenanthridines were isolated in moderate yield.
