摘要:
copper-based antibacterial agents based on amphiphilic copper complexes formed between copper and hydroxypyrones, such as maltol, are described. in other respects, the present invention relates to peg-based ointments showing that they are particularly effective for topical administration of copper amphiphilic complexes. in particular, peg ointments have been shown to limit bacterial growth, even when in the absence of the copper agent. however, this bacteriostatic effect is shown here to become a true biocidal effect when copper hydroxypyrones are added to the peg.são descritos agentes antibacterianos à base de cobre com base em complexos de cobre anfifílicos formados entre o cobre e as hidroxipironas, tal como o maltol. em outros aspectos, a presente invenção se refere a pomadas à base de peg mostrando que elas são particularmente eficazes para administração tópica de complexos anfifílicos de cobre. em particular, as pomadas de peg mostraram limitar o crescimento bacteriano, mesmo quando na ausência do agente de cobre. no entanto, este efeito bacteriostático é mostrado aqui para se tornar um verdadeiro efeito biocida quando as hidroxipironas de cobre são adicionadas ao peg.
