Full textWe have developed the synthesis of new acridinic monomers and dimers. Moreover, the N-arylation of heterocyclic amines using organometalic reagents wearing boron or bismuth has been also developped to yield different acridinic polycycles. This work needs the synthesis of two key intermediates: the 3-acetamido-6-aminoacridine and the 4-aminoacridine. Thus, we obtained five new series of heterocyclic acridinic monomers, two new series of acridinic dimers and one range of biacridines. All these new compounds are currently in biological testing

Full textNovel rotaxanes containing two 9-aryl-9-methoxy-10-methyl-9,10-dihydroacridine moieties (acridanes) at both ends at the molecular axle as recognition stations for the tetracationic ring CBPQT4+ were synthesized together with their acridinium counterparts. A new concept of controlling the ring movement within rotaxanes has been realized with these rotaxanes. Owing to Brownian molecular movement, the ring shuttles from one end of the axle to the other one in acridane rotaxanes. The shuttle process is stopped by converting two or one of the acridane stations into the corresponding acridinium unit. If both acridanes are transformed by addition of an acid, the ring resides on evasive stations present in the center of the axle. Photons convert only the unoccupied acridane station, thus the ring remains on the unchanged acridane station. The shuttle process can be switched on by addition of a base and by thermal reaction of the methoxide with the formed acridinium ion, respectively.

Full textThe present report describes the design and the synthesis of more than 70 new mono and bisacridinic derivatives substituted on positions 4 and 5, as well as their biological evaluation as anti-HIV, antileishmanial, antiproliferative and mutagenic agents. The aim of the convergent synthetic approach involved here is to valorize at best all the intermediates, as well as the direct fonctionnalization of the acridine by electrophilic substitution. A theoretical study of the reactivity of the acridine and its protonated form as well as an exhaustive review of the methods of direct fonctionnalization of the acridinic pattern were carried and were at the basis for this synthetic work. A synthetic approach of a new family of acridinic macrocycles linked on positions 4 and 9 is also developed

Full textCarbamazepine is a very usefull antiepileptic drug, widely used at the point of becoming an environmental marker of human activity. It is giving rise to rare but potentially lethal hypersensitivity reactions, with specific combination of skin manifestations, eosinophilia and multi-organ damage (DRESS syndrome). The pathophysiological hypotheses rely primarily to metabolites of carbamazepine, but the minor pathway of acridinic derivatives is little explored.The results obtained from ex vivo stimulation in our laboratory suggest both that acridine stimulates the secretion of interleukin-5 (main growth factor of eosinophils), and that the formation of acridine and acridone is possible in blood from primary metabolites (epoxide and iminostilbene). Clinical data show a decrease in blood levels of 9-hydroxymethyl-10-carbamoylacridan and in the ratio (acridine / acridone) during the state of DRESS. Co-treatment with valproic acid increases the basal rate of IL-5 and diverts, at least in part, to the metabolic profile of DRESS. The study of the action of environmental oxidative processes indicates that the purification processes by trickling filters and stabilization ponds increase the release of acridine, while activated sludge systems have little impact.Our work in human pharmacology positions acridine and acridone as regular blood metabolites, involved as markers or actors of the pathophysiology of DRESS. The determination of the metabolic profile appears warranted for atopic patients requiring co-therapy with valproic acid. Acridine also appears to be a marker of environmental interest

Full textFor this work we have examined the photolytic formation of acridinium ion within pseudorotaxanes and the resulting transformation of light energy into translational movement. This can be regarded as the first step towards (creating a) molecular machine. 9-phenyl-9-methoxyacridane distinguishes itself from its corresponding acridinium ions in terms of light absorption, shape, and electronic donor strength. The acridane can be regarded as candidates for photoswitching supramolecular units, because they can be transformed into positively charged acridinium ions. These ions generate an electron acceptor from an electron donor. The object of the following thesis is the development of a new synthetic approach to linear or makrocyclic systems, which contain acridane as a structural element. Macrocycles with electron-rich 9-phenyl-9-methoxyacridan units were prepared under high dilution conditions. The acridinium macrocycles are generated by photoheterolysis of this methoxy derivative, which has a thermal response to acridane macro cycles, thus closing the switching cycle. Heterolytic photodissociation occurs in alcohols, acetonitrile and toluene. Mixing alcohol with acentonitril can control the lifespan of the acridinium methoxide. Even after 10 switching cycles the system seemed unaffected. The molecular thread and macrocycles must be complementary in that they can interact by attracting forces, through generating an electron acceptor from an electron donor. The complex formation of acridan macrocycles with electron acceptor molecular thread was studied using spectrophotometric titration. As a result, photoswitchable pseudorotaxane was formed between acridan crown ethers and (2,2-bipyridine) molecular thread. In the context of this research, we have found that such a transformation is possible. A new, durable photoswitch has been developed, and using the 1H-NMR-spectroscope, we observed the molecular movement, which was made visible through the application of light.

Full textFor the first time we synthesized novel photoactive heterocyclic spiro-acridanes and studied their photochemical ring opening that leads to bipolar acridinium compounds; these, in turn, could thermally react to return to the spiro-acridane moiety. However, a side reaction via the photoexcited state resulted in 9-H-9-aryl-acridanes with an aldehyde side arm. This undesired reaction could be avoided by substituting the hydrogen atoms neighbouring the oxygen atom by methyl groups. With this enhancement a reversible photochromic system works. Depending on the solvent and the ring size, the lifetime of the zwitterions is in the range of milliseconds to seconds. The switching cycle could also be realized by the alternating addition of acid and base. The spiro-acridane unit was introduced into a molecular axle in order to construct a rotaxane using the wheel of cyclobis(paraquat-p-phenylene). The wheel shuttles between an alkoxy-phenyl-unit as evasive recognition station and the spiro-acridane station; but resides mainly on the first station because of the steric interference with the methyl groups present in the pyrane ring of the spiro-acridane. The spiro-acridane within the rotaxane was photochemically opened to give a rotaxane with a bipolar acridinium station. Calculations (MM2-level) suggest that the ring resides on the zwitterions due to the attraction between the negatively charged side-arm of the 9-aryl-acridinium unit and the positive charges of the wheel. The movement of the ring component can also be controlled by acid and base addition.
