Thiol-functionalized lipids were synthesized to exploit thiol-specific reaction principles for the selective conjugation of lipid moieties to peptides and proteins. Thioglycerol (3-mercapto-1,2-propanediol) protected as S-tert-butylthio derivative served as starting product for the esterification of the two hydroxy groups with identical saturated or unsaturated fatty acids as well as for the preparation of mixed diacyl derivatives. Reductive cleavage of the thiol protecting group produced the (RS)-1,2-di-O-acyl-3-thioglycerols (RS)- 2,3-diacyloxypropanethiols as suitable reagents for lipid modification of target molecules.
巯基功能化的脂质被合成,以利用巯基特异性反应原理,实现脂质部分与肽和蛋白质的选择性偶联。作为起始产物,硫代甘油(3-巯基-1,2-丙二醇)以S-叔丁基硫代衍生物形式保护,用于与相同的饱和或不饱和脂肪酸进行两个羟基的酯化,以及制备混合的二酰基衍生物。通过还原裂解巯基保护基团,得到(RS)-1,2-二-O-酰基-3-硫代甘油((RS)-2,3-二酰氧基丙硫醇),作为对目标分子进行脂质修饰的适宜试剂。
