envelope and cellular membrane. To inhibit HIV uptake and infection, we designed and synthesized analogs of GalCer. These amphiphiles and bolaamphiphiles consist of single and double hydrocarbon and/or fluorocarbon chain beta-linked to galactose and galactosamine. They derive from serine (GalSer), cysteine (GalCys), and ethanolamine (GalAE). The anti-HIV activity and cytotoxicity of these galactolipids
半乳糖神经酰胺(GalCer)是一种替代受体,允许HIV-1进入CD4(-)/ GalCer(+)细胞。该糖鞘脂识别HIV gp120的V3环,该环在HIV包膜和细胞膜的融合中起关键作用。为了抑制HIV的吸收和感染,我们设计并合成了GalCer的类似物。这些两亲物和两亲物由β-连接至半乳糖和半乳糖胺的单和双碳氢化合物和/或碳氟化合物链组成。它们源自丝氨酸(GalSer),半胱氨酸(GalCys)和乙醇胺(GalAE)。在CEM-SS(CD4(+)细胞系),HT-29,表达高水平GalCer受体和/或HT29的CD4(-)细胞系中,对这些半乳糖脂的抗HIV活性和细胞毒性进行了体外评估。基因修饰以表达CD4。GalSer和GalAE衍生物,在水性介质中或作为脂质体制剂的一部分进行的测试显示适度的抗HIV-1活性(IC50在20-220 microM范围内),而GalCys衍生物均未发现有活性。
