The present invention relates to processes for preparing linkers that are useful in the conjugation of therapeutic molecules (e.g., cytotoxic agents) with targeting moieties (e.g., proteins, peptides, antibodies, nanoparticles, nucleic acids). During said processes lipases like lipase B from Candida antarctica were used for enantioselective resolution of (S,S)-2-benzylthiocyclohexanol or (S,S)-2-benzylthiocycloheptanol in presence of acylating agent which are reduced for deprotection to yield (S,S)-2-mercaptocyclohexanol or (S,S)-2-mercaptocyclopentanol which can then be used for linking therapeutic with targeting moieties.
本发明涉及制备链接剂的过程,该链接剂可用于将治疗分子(例如细胞毒素)与靶向基团(例如蛋白质、肽、抗体、纳米粒子、核酸)结合。在该过程中,利用来自南极酵母的脂肪酶B进行对(S,S)-2-苄基硫代环己醇或(S,S)-2-苄基硫代环庚醇的不对称分离,同时存在酰化剂,然后还原去保护基团,得到(S,S)-2-巯基环己醇或(S,S)-2-巯基环戊醇,这些化合物可用于将治疗分子与靶向基团连接起来。
