The present invention relates to non-membrane disruptive and p53 activating stapled peptides, as well as methods of treatment of cancer involving the use of these peptides. In one embodiment, the peptide comprises or consist of the amino acid sequence of TSFXaa1EY-WXaa3LLXaa2, where Xaa1 is (R)-2-(7′-octenyl)alanine or derivative thereof, or is (R)-2-(4′-pentenyl)alanine or derivative thereof; and Xaa2 and Xaa3 are independently any type of amino acid or modified amino acid. In another embodiment, the peptide comprising or consisting of the amino acid sequence of TSFXaa1EYW Xaa3LLXaa2ENXaa5, wherein Xaa1 and Xaa3 are any type of amino acid or modified amino acid; Xaa2 is S, or P, or (S)-2-(4′-pentenyl)alanine or a derivative of (S)-2-(4′-pentenyl)alanine; and wherein Xaa5 is F or Y.
本发明涉及非膜破坏性和 p53 活化的钉状肽,以及使用这些肽治疗癌症的方法。在一个实施方案中,肽包括或由TSFXaa1EY-WXaa3LLXaa2的氨基酸序列组成,其中Xaa1是(R)-2-(7′-辛烯基)丙氨酸或其衍生物,或者是(R)-2-(4′-戊烯基)丙氨酸或其衍生物;Xaa2和Xaa3独立地是任何类型的氨基酸或修饰氨基酸。在另一个实施方案中,包括或由TSFXaa1EYW Xaa3LLXaa2ENXaa5的氨基酸序列组成的肽,其中Xaa1和Xaa3是任何类型的氨基酸或修饰氨基酸;Xaa2是S,或P,或(S)-2-(4′-戊烯基)丙氨酸或(S)-2-(4′-戊烯基)丙氨酸的衍生物;其中Xaa5是F或Y。
