structure–activity relationship study on polyamine derivatives led to the synthesis and the determination of antikinetoplastid activity of 17 compounds. Among them, a spermidinederivative (compound 13) was specifically active in vitro against Leishmania donovani axenic amastigotes (IC50 at 5.4 μM; Selectivity Index >18.5) and a sperminederivative (compound 28) specifically active against Trypanosoma

Among the synthesized compounds, naphthoquinone amines, 5 (0.8; 0.6; 0.8), 14 (0.8; 0.6; 0.5) and the amine precursor, 4 (1.3; 0.3; 1.0) displayed potent anticancer activities. A tumor targeting drug delivery system was achieved by synthesizing the conjugate 6 (1.4; 0.5; 1.1) of naphthoquinone-amine 5 and Biotin which also proved its potency. Finally, to introduce polyamine conjugate, spermidine was attached

A series consisting of ianthelliformisamimes A, B, and C as well as its synthetic analogues was prepared in high chemical yield, from 27 to 91%, using peptide coupling as the key step, and the compounds were evaluated for their in vitro antibiotic enhancer properties against resistant Gram-negative bacteria and clinical isolates. The mechanism of action of one of these derivatives against Pseudomonas aeruginosa when combined with doxycycline was precisely evaluated utilizing bioluminescence to measure ATP efflux and fluorescence to evaluate membrane depolarization.

A series of artemisinin-spermidine conjugates designed to utilise the upregulated polyamine transporter found in cancer cells have been prepared. These conjugates were evaluated against human promyelocytic leukaemia HL-60 cells and chloroquine-sensitive 3D7 Plasmodium falciparum and several show promising anticancer and antimalarial activity. Although some limitations in this vector-based approach are apparent, a number of high potency Boc-protected analogues were identified with activity against malaria parasites as low as 0.21 nM.

Iron chelation in tumoral cells has been reported as potentially useful during antitumoral treatment. Our aim was to develop new polyaminoquinoline iron chelators targeting tumoral cells. For this purpose, we designed, synthesized, and evaluated the biological activity of a new generation of iron chelators, which we named Quilamines, based on an 8-hydroxyquinoline (8-HQ) scaffold linked to linear polyamine vectors. These were designed to target tumor cells expressing an overactive polyamine transport system (PTS). A set of Quilamines bearing variable polyamine chains was designed and assessed for their ability to interact with iron. Quilamines were also screened for their cytostatic/cytotoxic effects and their selective uptake by the PTS in the CHO cell line. Our results show that both the 8-HQ moiety and the polyamine part participate in the iron coordination. HQ1-44, the most promising Quilamine identified, presents a homospermidine moiety and was shown to be highly taken up by the PTS and to display an efficient antiproliferative activity that occurred in the micromolar range. In addition, cytotoxicity was only observed at concentrations higher than 100 mu M. We also demonstrated the high complexation capacity of HQ1-44 with iron while much weaker complexes were formed with other cations, indicative of a high selectivity. We applied the density functional theory to study the binding energy and the electronic structure of prototypical iron(III)-Quilamine complexes. On the basis of these calculations, Quilamine HQ1-44 is a strong tridentate ligand for iron(III) especially in the form of a 1:2 complex.
