The present invention provides a peptide of formula (I) or a pharmaceutical salt thereof wherein "m", "n", "p", and "q" represent integers and are selected from 0 and 1; and "r" is comprised from 1 to 10; a linker birradical of formula (II), which is connecting an alpha carbon atom of an amino acid located at position "i" in the peptide sequence of formula (I) with an alpha carbon atom of an amino acid located at position "i+4" or "i+7"in the peptide sequence of formula (I); a C-terminal end corresponding to –C(O)R4; and a N-terminal end corresponding to –NHR5. Alternatively, the present invention provides a peptide or a pharmaceutical salt thereof which has an amino acid sequence with an identity from 85% to 95% with respect to sequence SEQ ID NO: 9: The peptides of the invention show anticancer activity. (I)
本发明提供了公式(I)的肽或其药物盐,其中“m”、“n”、“p”和“q”代表整数,可选择为0和1;“r”由1到10组成;公式(II)的连接双基团,它将公式(I)中位于位置“i”的氨基酸的α-碳原子与公式(I)中位于位置“i+4”或“i+7”的氨基酸的α-碳原子连接起来;一个对应于–C(O)R4的C-末端;以及一个对应于–NHR5的N-末端。或者,本发明提供了一种具有与序列SEQ ID NO: 9的同源性在85%到95%之间的氨基酸序列的肽或其药物盐。本发明的肽显示出抗癌活性。(I)
