Our attempts to N-arylate anilines with 2-iodotriphenylene and then cyclize the adjacent carbonyl group are reported.
Chromatographic separation of the leaves of Teclea trichocarpa (Engl.) Engl. (Rutaceae) used traditionally by Akamba tribe in Kenya yielded three acridone alkaloids, a furoquinoline alkaloid and two triterpenoids. The total extract (methanol) of the leaves of this plant and the isolated compounds were screened for in vitro for cytotoxicity and against parasitic protozoa, Plasmodium falciparum, ...
A photocatalytic system for CO2 reduction exhibiting visible-light harvesting was developed by preparing a hybrid consisting of a supramolecular metal complex as photocatalyst and periodic mesoporous organosilica (PMO) as light harvester. A Ru(II) Re(I) binuclear complex (RuRe) with methylphosphonic acid anchor groups was adsorbed on acridone or methylacridone embedded in the walls of PMO mes...
Abstract Crown ethers containing an acridone or acridine unit are successfully applied opto- and electrochemical cation sensors. The heteroaromatic of these macrocycles can be in different forms during the applications, which have a strong influence on sensing behavior. Moreover, case acridono-macrocycles prototropic equilibrium takes place upon complexation, is effected by physicochemical char...
This review focuses on pyridoacridine-related metabolites as one biologically interesting group of alkaloids identified from marine sources. They are produced by marine sponges, ascidians and tunicates, and they are structurally comprised of four to eight fused rings including heterocycles. Acridine, acridone, dihydroacridine, and quinolone cores are features regularly found in these alkaloid s...
A Mobil Composition of Matter (MCM)-41 type mesoporous silica material containing N-propylacridone groups has been successfully prepared by co-condensation of an appropriate organic precursor with tetraethyl orthosilicate (TEOS) under alkaline sol-gel conditions. The resulting material was fully characterized by means of X-ray diffraction (XRD), N(2)-adsorption-desorption, transmission electron...
