punctata showed that the activity of analog I (IC(50): 0.09 muM) was more active than that of the C-terminal pentapeptide (Tyr-Xaa-Phe-Gly-Leu-NH(2), IC(50): 0.13 muM) it mimicked and the activity of the analog II (IC(50): 0.13 muM) proved roughly equivalent to the C-terminal pentapeptide. The results indicate that a new simple mimicry for Tyr-Xaa-Phe-Gly has been discovered; analog I may be a novel compound

A novel bidentate ligand 1,6-bis(benzylidene)hexanediamine was synthesized and its eight ruthenium bis(bypyridine)sulphoxide complexes with the general formula [cis/trans-RuCl2(SO)2(N-N)](L); were SO = dimethyl sulphoxide (DMSO)/tetramethylene sulphoxide (TMSO), (N-N) = 1,10-phenanthroline/2,2-bipyridyl, (L) = bridging ligand were synthesized. These complexes were characterized by elemental analysis, IR, UV/visible, 1H NMR, 13C NMR and 2D NMR spectroscopy. All complexes were found to show antibacterial property against E. coli and the pyridal ligands co-ordinate through a Ru–N bond in all cases.

The invention relates to N-bridged polynitrons and their use for cross-linking of unsaturated polymers, as well as a curable composition comprising (a) a N-bridged polynitron, (b) an unsaturated polymer or a mixture of polymers, wherein at least one unsaturated polymer contains unsaturated functions or functional groups which can react with the polynitron, (c) optionally fillers, (d) optionally pigments, (e) optionally additives such as plasticizers, stabilizers, photoinitiators, and (f) optionally, other cross-linking agents such as polyisocyanates, bisdienes, polyoxaziridines, and their use as adhesives, rubber, filling, sprayable thick-layer filler, ink, paint, powder paint, waterborne paint or solvent based paint. Further, the invention relates to cross-linking products obtainable by curing the curable composition according to the present invention.

The development of new chemical entities against the major diseases caused by parasites is highly desired. A library of thirty diamines analogs following a minimalist approach and supported by chemoinformatics tools have been prepared and evaluated against apicomplexan parasites.

A series of 25 N,N′-substituted diamines were prepared by controlled reductive amination of free aliphaticdiamines with different substituted benzaldehydes. The library was screened in vitro for antiparasitic activity on the causative agents of human African trypanosomiasis, Chagas’ disease and visceral leishmaniasis. The most potent compounds were derived from a subset of diamines that contained
