Glycomimetic compounds as anti-infectious against pathogens lectins

摘要

The present invention relates to a calixarene-based glycosylated compound (I) having the formula: (I) wherein D is independently selected in the group comprising a —CH₂-group, an oxygen atom, a sulphur atom, a sulfinyl group or a sulfonyl group, E is independently selected in the group comprising a hydrogen, an alkyl having from 1 to 10 carbon atoms, an aryl having from 6 to 20 carbon atoms, a nitrogen dioxide group, an azide group, an amino group, a guanidinium group, a halogen atom, a —CH₂ R group wherein R is a hydroxyl, a halogen, an amino group, a N(alkyl)₂ group, a NH(alkyl) group, or E represents a —CO—R′ wherein R′ is a hydrogen atom, a hydroxyl group or an amino, B represents a A-C group wherein A is independently selected in the group comprising an oxygen atom, a sulfur atom, a NH group or a (CH₂)_i group, i being an integer from 1 to 10, C is independently selected in the group comprising a hydrogen, an alkyl, an alkenyl, an alkynyl, or C is a group of formula (II). The present invention also relates to a pharmaceutical composition characterized in that it comprises the said calixarene-based glycosylated compound (I), in combination with pharmaceutically acceptable carriers or diluents. The present invention also relates to the use of the said calixarene-based glycosylated compound (I) or the said pharmaceutical composition, for the manufacture of a drug intended to prevent or treat bacterial infections from pathogens that use lectins in the first steps of infection.; ;
