A clickable, affinity-basedprobe (AfBP), which was modified from staurosporine (a natural product kinase inhibitor), has been synthesized and used in situ for activity-based proteomeprofiling of potential cellular targets of staurosporine in HepG2 cancer cells.
A purpose of the present invention is to provide a compound that has a functional group available for formation of a conjugate at its C-terminus and that has cytotoxicity. The present invention provides a peptide derivative represented by the formula below or a pharmaceutically acceptable salt thereof.
A peptide derivative represented by Formula (I) or a pharmaceutically acceptable salt thereof:
wherein X represents an oxygen atom or NR, Y represents NH2, N(Me)H, SH, OH, or phenyl in which any one of hydrogen atoms is replaced by NH2 or OH, and R represents a hydrogen atom or C1-C3 alkyl, provided that the derivative where X is NH, and Y is NH2, and the derivative where X is NH, and Y is N(Me)H are excluded.
由式(I)代表的多肽衍生物或其药学上可接受的盐:
其中 X 代表氧原子或 NR,Y 代表 NH2、N(Me)H、SH、OH 或其中任一氢原子被 NH2 或 OH 取代的苯基,R 代表氢原子或 C1-C3 烷基,但不包括 X 为 NH、Y 为 NH2 的衍生物和 X 为 NH、Y 为 N(Me)H 的衍生物。
