The constituents of Citrus plants were investigated to develop useful agents that are effective in cancer chemoprevention. We examined the roots and bark of the roots of various Citrus plants, resulting in the isolation of many novel compounds. Their structures were determined using spectroscopic methods, especially 2D-NMR spectra. The following new compounds of constituents were found: dimeric...

We report here in vitro and in vivo antitumour activity study of a series of 1,3-dimethyl-N substituted acridone derivatives. All the molecules have been designed on the basis of the presence of specific recognition patterns consisting of electron donor, carbons. Chloro groups with precise spatial separation and structural features (lipophilicity, positive charge at neutral pH and presence of a...

one of the methods to enhance bio-accessibility of drugs like acridone and its oxime is toform inclusion complexes with β-cyclodextrin. the formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. the aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. the studyof thermodynamic parameters like δg,...

This study aimed to monitor PAC availability to the oligochaete Lumbriculus variegatus during 28 days of exposure to spiked sediments, in order to obtain reliable chronic effect concentrations for reproduction. Sediment toxicity tests were performed using three pairs of PAC isomers: two homocyclic compounds (anthracene and phenanthrene), two azaarenes (acridine and phenanthridine), and the two ...
