Synthesis and in vitro evaluation of leishmanicidal and trypanocidal activities of N-quinolin-8-yl-arylsulfonamides
摘要:
In the present paper 12 N-quinolin-8-yl-arylsulfonamides synthesized by coupling 8-aminoquinolines with various arylsulfonylchlorides were assayed in vitro against Leishmania amazonensis, L. chagasi and Trypanosoma cruzi strains. This series of new compounds were found to be selective for Leishmania spp. promastigote and amastigote forms. The most active compound was the N-(8-quinolyl)-3,5-diflu. uoro-benzenesulfonamide 10 with an IC50 against L. amazonensis and L. chagasi of 2.12 and 0.45 mu M, respectively. The less cytotoxic biphenyl derivative 7 was very e. ffective against intracellular L. amazonensis with a reduction of macrophage cell infection of 82.1% at 25 mu M. In addition, a copper complex 17 of an inactive ligand was readily synthesized and showed high leishmanicidal and trypanocidal activity against both extra and intracellular forms.

The invention relates to electroluminescent materials containing organic luminescent substance. The inventive novel electroluminescent material comprises an electron injecting layer, an active luminescent layer based on a luminescent substance, a hole-transport layer and a hole-injecting layer. The material contains metallocomplexes of quinoline-sulfanylamine derivatives in the form of a luminescent substance. The inventive electroluminescent material exhibits the increased time resource, resulting from the high resistance of the active luminescent layer to crystallisation and hydrolysis, and the high heat resistance of the hole-transport layer.

The synthesis and properties of a newclass of electroluminescent metalcomplexes based on quinoline ligands containing the sulfanylamino group in position 8 are described. These complexes contain C-N-M-N chains in the chelate cycles instead of the traditionally used C-O-M-N chains.
