The invention provides new synthetic routes for cardiolipin with different fatty acids and/or alkyl chains with varying chain length and also with or without unsaturation, particularly a short-chain cardiolipin. The methods comprise reacting a 1,2-O-sn-diacyl/1,2-O-sn-dialkyl glycerol or a 2-O-protected glycerol, with a phosphoramidite reagent or a phosphate triester to produce a protected cardiolipin, which is deprotected to prepare the short chain cardiolipin. The reaction schemes can be used to generate new variants of cardiolipin. The cardiolipin prepared by the present methods can be incorporated into liposomes, which can also include active agents such as hydrophobic or hydrophilic drugs. Such liposomes can be used to treat diseases or in diagnostic and/or analytical assays. Liposomes can also include ligands for targeting a particular cell type or specific tissue.
本发明提供了一种合成不同脂肪酸和/或不同链长烷基的心磷脂的新合成路线,以及具有或不具有不饱和度,特别是一种短链心磷脂。该方法包括将1,2-O-sn-二酰基/1,2-O-sn-二烷基甘油或2-O-保护甘油与磷酸酰胺试剂或磷酸三酯反应以产生受保护的心磷脂,然后去保护以制备短链心磷脂。该反应方案可用于生成心磷脂的新变体。通过本方法制备的心磷脂可以被纳入到脂质体中,这些脂质体还可以包括疏水性或亲水性药物等活性剂。这样的脂质体可以用于治疗疾病或在诊断和/或分析检测中使用。脂质体还可以包括用于靶向特定细胞类型或特定组织的配体。
