Cranberries (Vaccinium macrocarpon) have long been the focus of interest for their beneficial effects in preventing urinary tract infections. Among cranberry compounds, a group of proanthocyanidins (PACs) with A-type linkages were isolated which exhibit bacterial anti-adhesion activity against uropathogenic Escherichia coli strains. These PAC inhibit P-fimbriae synthesis and induce a bacterial deformation. This activity was demonstrated on both antibiotic susceptible and resistant bacteria. This review focused on the last discoveries in the knowledge of cranberry effects.
蔓越莓(大果越桔)长期以来因其在预防尿路感染方面的有益作用而备受关注。在蔓越莓化合物中,分离出了一组具有A型连接的原花青素(PACs),它们对尿路致病性大肠杆菌菌株具有细菌抗粘附活性。这些PAC抑制P菌毛的合成并诱导细菌变形。这种活性在抗生素敏感和耐药细菌中均得到证实。本综述聚焦于蔓越莓作用相关知识的最新发现。
