T.; Jeong, Keunsoo; Go, Eun Min; Cho, Yuri; Lee, Seokyung; Jin, Seongeon; Hwang, Suk-Won; Jang, Joo Hee; Kang, Chi Soo; Bang, Woo-Young; Lee, Eunji; Kwak, Sang Kyu; Kim, Sehoon; Ryu, Ja-Hyoung published an article.Category: bromides-buliding-blocks The title of the article was Heterochiral Assembly of Amphiphilic Peptides Inside the Mitochondria for Supramolecular Cancer Therapeutics. And the article contained the following:
Self-assembly of peptides containing both L- and D-isomers often results in nanostructures with enhanced properties compared to their enantiomeric analogs, such as faster kinetics of formation, higher mech. strength, and enzymic stability. However, occurrence and consequences of the heterochiral assembly in the cellular microenvironment are unknown. In this study, we monitored heterochiral assembly of amphiphilic peptides inside the cell, specifically mitochondria of cancer cells, resulting in nanostructures with refined morphol. and biol. properties owing to the superior interaction between the backbones of opposite chirality. We have designed a mitochondria penetrating tripeptide containing a di-Ph alanine building unit, named as Mito-FF due to their mitochondria targeting ability. The short peptide amphiphile, Mito-FF co-assembled with its mirror pair, Mito-ff, induced superfibrils of around 100 nm in diameter and 0.5-1μm in length, while enantiomers formed only narrow fibers of 10 nm in diameter The co-administration of Mito-FF and Mito-ff in the cell induced drastic mitochondrial disruption both in vitro and in vivo. The exptl. and theor. analyses revealed that pyrene capping played a major role in inducing superfibril morphol. upon the co-assembly of racemic peptides. This work shows the impact of chirality control over the peptide self-assembly inside the biol. system, thus showing a potent strategy for fabricating promising peptide biomaterials by considering chirality as a design modality. The experimental process involved the reaction of (6-Bromohexyl)triphenylphosphonium bromide(cas: 83152-22-1).Category: bromides-buliding-blocks
