The invention relates to the use of polysiloxanes which comprise a plurality of quaternary ammonium groups in the molecule in cosmetic or pharmaceutical compositions for the cleaning and care of keratin fibers, in particular of human hair. The improvement in the shine and in the color protection of the hair is achieved if the polysiloxanes are used in an amount in the range from 0.01 to 30%.
The elucidation of these NMR characteristics of B(1a)(2e) allowed the more rapid evaluation of the enantiotopic grouprecognition in many other borate complexes, which range from 57:43 to 67:33 at room temperature. The recognition of the (after complexation) diastereotopic dimethylamino groups of 2e in the borate complex B(1a)(2e) was utilized in a consecutive methylation reaction, which yielded enantiomerically

Amino(bis-amino)derivatives of 2-propanol were synthesized by ringopening in epoxides under the action of amines in water medium using environmentally safe methods. The structure of the compounds obtained was established by elemental analysis and the IR, 1H and 13C NMR spectroscopy. It was found that these substances are effective bactericides. They suppress the growth of the sulfate-reducing bacteria

One aspect of the invention relates to substitute quinolines with antimalarial activity, and compositions and kits comprising at least one of them. Another aspect of the invention relates to methods for the treatment or prevention or both of malaria comprising administering to a subject a therapeutically effective amount of such a compound. Importantly, a number of the compounds show excellent potency against both chloroquine-sensitive and chloroquine-resistant strains.
