The mutagenic properties of acridines on pneumococcus are described. All seven acridines tested were mutagenic at the amiA locus conferring a resistance to 10(-5) M aminopterin. The effects of quinacrine were more specifically investigated. It was observed that: mutants can be obtained only by treatment of exponentially growing cells; a sharp maximum mutagenic effect occurs at a concentration s...

A simple and convenient one-step method for synthesis of acridines and their derivatives from condensation of aromatic aldehydes, cyclic diketones, and aryl amines using Cu-doped ZnO nanocrystalline powder as a catalyst is reported. The present protocol provides several advantages such as good yields, short reaction time, easy workup, and simplicity in operation.

The Pd-catalyzed condensation of 2-bromostyrene and 2-chloroaniline derivatives yields stable diphenylamine intermediates, which are selectively converted to five-, six-, or seven-membered heteroaromatics (indoles, carbazoles, acridines, and dibenzazepines). The selectivity of these intramolecular transformations is uniquely ligand-controlled and offers efficient routes to four important classe...

The aim of the work was to establish spect­rum biological activity new derivatives 9-bromo-1,2,3,4-tetrahydroacridine due limi­ted amount literature data. In silico prediction selected bromo-derivatives hydrogenated acridines performed using SuperPred 3.0 web resource. obtained results were compared with active drugs that contain acridine cycle in their structure - Tacrine, Amiridine and Amsacr...

We have used the forward mutation to resistance to 6 azauracil to test the mutagenicity of rivanol (6,9 diamino 2-ethoxy acridine) on Escherichia coli. Rivanol has been used to induce therapeutic abortions in midpregnancy and is considered safe and effective for this purpose. The findings reported here that rivanol, like other acridines, is a mutagen, at least in procaryotes, suggests that such...
