prevalent antigen frequently recognized by antibodies in late‐stage LD. Here we report a convenient route for the chemical synthesis of ACGal by employing a combination of chemical synthesis steps with enzymatic transformations. This synthesized molecule was compared with bacterial extracts by immunoblots with patient sera, confirming the preserved antigenicity. Next, a glycolipidlibrary derived from
莱姆病(LD)是欧洲,北美和亚洲最常见的壁虱传播疾病。LD的病原体是Borrelia burgdorferi sensu lato组的螺旋体,其脂质含量为干重的25–30%。主要糖脂胆固醇6- ö酰基-β- d -galactopyranoside(ACGal),存在于博氏疏螺旋狭义,B. afzelii,和B. garinii,是一种特异且高度流行的抗原,经常被晚期LD的抗体识别。在这里,我们报告了通过化学合成步骤与酶促转化相结合的化学合成ACGal的便捷途径。通过用患者血清进行免疫印迹将该合成的分子与细菌提取物进行比较,确认了保留的抗原性。接下来,设计并合成了衍生自具有脂肪酰基部分变化的天然分子的糖脂文库和其中胆固醇已被取代的衍生物。化学结构通过1D和2D NMR光谱法和质谱法确认。将天然和合成的糖脂用于免疫印迹,以确定患者血清中抗体识别的表位。通过这种方法,我们可以证明半乳糖 胆固醇

Compositions and methods, including novel homogeneous microparticulate suspensions, are described for treating acute wounds, chronic wounds and/or a wound or epithelial tissue surface that contains bacterial biofilm, including unexpected synergy between bismuth-thiol (BT) compounds and certain antibiotics, to provide topical formulations including antiseptic formulations, for management and promotion of wound healing and in particular infected wounds. Previously unpredicted antibacterial properties and anti-biofilm properties of disclosed BT compounds and BT compound-plus-antibiotic combinations are also described, including preferential efficacies of certain such compositions for treating gram-positive bacterial infections, and distinct preferential efficacies of certain such compositions for treating gram-negative bacterial infections.

Compositions and methods, including novel homogeneous microparticulate suspensions, are described for treating natural surfaces that contain bacterial biofilm, including unexpected synergy or enhancing effects between bismuth-thiol (BT) compounds and certain antibiotics, to provide formulations including antiseptic formulations. Previously unpredicted antibacterial properties and anti-biofilm properties of disclosed BT compounds and BT compound-plus-antibiotic combinations are also described, including preferential efficacies of certain such compositions for treating certain gram-positive bacterial infections, and distinct preferential efficacies of certain such compositions for treating certain gram-negative bacterial infections.
