1. Cyclopeptides from Stellaria yunnanensis
Y R Zhao, J Zhou, X K Wang, X L Huang, H M Wu, C Zou Phytochemistry. 1995 Nov;40(5):1453-6. doi: 10.1016/0031-9422(95)00351-7.
In a previous paper, we reported the structural elucidation of stellarin A, a new cyclic heptapeptide, from the fresh roots of Stellarina yunnanensis Franch. Further chemical study on this plant led to the isolation of another two new cyclopeptides named stellarin B and C. Their structures were established to be cyclo(Gly-Ser-HOIle-Phe-Phe-Ala) and cyclo(Gly-Ser-HOIle-Phe-Phe-Ser), respectively, by spectral methods.
2. Reversibly Thermochromic Cyclic Dipeptide Nanotubes
Min Jeong Seo, Jisoo Song, Chandra Kantha, Mohammed Iqbal Khazi, Umesha Kundapur, Jung-Moo Heo, Jong-Man Kim Langmuir. 2018 Jul 17;34(28):8365-8373. doi: 10.1021/acs.langmuir.8b00743. Epub 2018 Jul 6.
Owing to their capability of forming extensive hydrogen bondings and the facile introduction of chirality, cyclic dipeptides (CDPs) have gained great attention as scaffolds for functional supramolecules. Surprisingly, introduction of a photopolymerizable diacetylene (DA) moiety to the CDP afforded nanotubular structures with enhanced stability and reversible thermochromism. A series of CDP-containing DAs (CDP-DAs) are prepared by coupling 10,12-pentacosadiynoic acid with CDPs, cyclo(-Gly-Ser) and cis/trans cyclo(-Ser-Ser). Fabrication of CDP-DA self-assemblies in a polar chloroform and methanol solvent mixture affords nanotubes comprising single-wall and multiwall structures. The self-assembly behavior and morphology characteristic are examined by scanning electron microscopy and transmission electron microscopy. Next, X-ray diffraction analysis confirms well-ordered lamellar structures with a perfect agreement with the bilayer formation leading to the tubular structure via lamellar scrolling behavior. Upon UV irradiation, monomeric CDP-DA tubular assemblies result in the blue-colored CDP/polydiacetylene (PDA) nanotubes. Interestingly, CDP/PDA nanotubes exhibit a reversible blue-to-red color change for over 10 consecutive thermal cycles. The CDP-DA/PDA supramolecular system demonstrates potential applications in developing stimulus-responsive functional materials.
