The present invention relates to a method for preparing a biomaterial having selectively functionalized tyrosine, a biomaterial having selectively functionalized tyrosine, and a pharmaceutical composition containing the same as an active ingredient. The method for preparing a biomaterial to which a compound represented by formula 2 is coupled, of the present invention, allows the compound represented by formula 2 to be selectively coupled, in a high yield in a biomaterial, to tyrosine, which is present on the surface of an aqueous solution such that the coupling thereof to amino acids other than tyrosine does not occur and, when only one tyrosine is present, heterogeneous mixtures are not present and the inherent activity of the biomaterial is maintained, and thus the compound can be effectively used as a pharmaceutical composition containing a biomaterial drug as an active ingredient. In addition, the method can selectively functionalize tyrosine, and thus can be effectively used for tyrosine functionalization in a biomaterial.
本发明涉及一种制备具有选择性功能化
酪氨酸的
生物材料的方法,具有选择性功能化
酪氨酸的
生物材料,以及含有该
生物材料作为活性成分的药物组合物。本发明的一种制备
生物材料的方法,其中将由式2表示的化合物偶联到
生物材料,使得该化合物能够选择性地偶联到
酪氨酸,且在
生物材料中的产率较高,
酪氨酸位于
水溶液表面,使得其与
酪氨酸以外的
氨基酸不发生偶联,当只有一个
酪氨酸存在时,不会出现异质混合物,同时保持
生物材料的固有活性,因此该化合物可以有效地用作含有
生物材料药物的药物组合物的活性成分。此外,该方法可以选择性功能化
酪氨酸,因此可以有效地用于
生物材料中的
酪氨酸功能化。
