TAILIEUCHUNG - Báo cáo khoa học: Cell-penetrating peptide-conjugated XIAP-inhibitory cyclic hexapeptides enter into Jurkat cells and inhibit cell proliferation

X-Linked inhibitor of apoptosis protein (XIAP) is a member of the inhibitor of apoptosis protein family that is overexpressed in human can-cers. There is great interest in the development of XIAP inhibitors, which are predicted to promote apoptosis in cancer cells and thus have therapeutic potential. | ỊFEBS Journal Cell-penetrating peptide-conjugated XIAP-inhibitory cyclic hexapeptides enter into Jurkat cells and inhibit cell proliferation Yusuke Sasaki1 Motoko Minamizawa1 Akihiro Ambo1 Shigeki Sugawara2 Yukiko Ogawa and Kazuo Nitta2 1 Department of Biochemistry Tohoku PharmaceuticalUniversity Sendai Japan 2 Institute of Molecular Biomembrane and Glycobiology Tohoku PharmaceuticalUniversity Sendai Japan Keywords antiproliferative activity apoptosis cell-penetrating peptide Jurkat cell XIAP inhibitory cyclic hexapeptide Correspondence Y.

There is great interest in the development of XIAP inhibitors which are predicted to promote apoptosis in cancer cells and thus have therapeutic potential. A cyclic hexapeptide CH CPFKQC which is one of the consensus motifs that can bind to the baculovirus IAP repeat 2 domain of XIAP has been identified using phage-displayed combinatorial chemistry techniques Tamm I Trepel M Cardo-Vila M Sun Y Welsh K Cabezas E Swatterthwait A Arap W Reed JC Pasqualini R 2003 Peptides targeting caspase inhibitors. J Biol Chem 278 14401-14405 . In this study we designed and synthesized covalently linked conjugates of CHs cyclo Cys-Pro-Xaa-Lys-Gln-Glu -CO- -NH2 Xaa various amino acids cyclization via a peptide bond between the N-terminal amino group of Cys1 and the side-chain carboxylic acid of Glu6 and a cell-penetrating peptide CPP Ac-Cys-Trp- Arg 8-Lys-NH2. CH-CPP conjugates CHCPPs with aromatic and hydrophobic Xaa residues such as Phe CHCPP 1 2 .
