Abstract:
This review deals with the fully aromatic quaternary benzo[c]phenanthridine alkaloids in several aspects. Firstly nomenclature principles for numbering fused heterocycles are given. Then the richest botanical sources of quaternary benzo[c]phenanthridines are mentioned as well as isolation, separation and determination methods are presented. The emphasis of this survey is focused on chemical reactivity. The main pharmacological effects of quaternary benzo[c]phenanthridine alkaloids are discussed.

Abstract:
Purpose. This study describes the antibacterial effect of extracts and compounds isolated from the aerial part of Chelidonium majus Linn.

The activities were evaluated by using the macrobroth dilution method and reported as the MICs/MBCs. Results. Bioassay-guided fractionation of the most active extract from the aerial parts (EtOAc) led to the isolation of benzo[c]phenanthridine-type alkaloids 8-hydroxydihydrosanguinarine (hhS), 8-hydroxydihydrochelerythrine (hhC), which were potently

In this study, we report the synthesis, antibacterial and anticancer evaluation of 38 novel phenanthridines that were designed as analogs of the benzo[c]phenanthridine alkaloids. The prepared phenanthridines differ from the benzo[c]phenanthridines in the absence of a benzene A-ring. All novel compounds were prepared from 6-bromo-2-hydroxy-3-methoxybenzaldehyde in several synthetic steps through reduction of Schiff bases and accomplished by radical cyclization. Twelve derivatives showed high antibacterial activity against Bacillus subtilis, Micrococcus luteus and/or Mycobacterium vaccae at sing

Abstract:
A novel and green synthesis of 2,3-dimethoxy-8,10-methylenedioxy benzo[c]cinnoline 7 is herein described. This compound is structurally related to benzo[i]phenanthridine, a class of potent topoisomerase I inhibitors such as nitidine. While nitidine was found to be toxic, the benzo[c]cinnoline derivative 7 may circumvent that by not being a Schiff base. A conveniently short synthetic plan was implemented involving a novel solvent- and catalyst-free cross-coupling biarylation of halogenated nitroarenes 2 and 5 using a high speed ball milling (HSBM) procedure.
