Synthesis of Pro-xylane: a new biologically active C-glycoside in aqueous media
Bioorg Med Chem Lett 2009 Feb 1;19(3):845-9.PMID:19135365DOI:10.1016/j.bmcl.2008.12.037.
The scope and limitation of Lubineau's reaction were evaluated for the synthesis of C-glycosides (compounds 1-13). Further transformation of side chain carbonyl was also achieved (compounds 16-23). Optimization of these two steps was investigated in xylose case. Some of the compounds were shown to stimulate sulfated glycosaminoglycans (GAGs) synthesis. Compound 20 (called Pro-xylane) was identified as the best activator of GAGs biosynthesis. Pro-xylane was developed using environmentally friendly conditions relevant to 'Green-Chemistry' principles and launched on the market in September 2006. This compound is the first example of 'Green' chemical used in cosmetic.
Improved Stability of Blue Colour of Anthocyanins from Lycium ruthenicum Murr. Based on Copigmentation
Molecules 2022 Sep 18;27(18):6089.PMID:36144823DOI:10.3390/molecules27186089.
Natural blue food colourant is rare. The aim of this work was to screen compounds from the common copigments that could improve the blue tones of anthocyanins (ACNs) and to investigate the effect of different copigments on the colour stability of anthocyanins in neutral species. International Commission on Illumination (CIE) colour space, UV, IR, NMR, atomic force microscopy (AFM) and computational chemistry methods were utilised to evaluate ACNs from Lycium ruthenicum Murr. (LR), which is complexed with food additives and biological agents. The results indicate that Pro-xylane (PX), Ectoin (ECT) and dipotassium glycyrrhizinate (DG) enhance the blue colour of the ACNs. ACNs-PX presents a colour close to Oxford Blue and has a surface height of 2.13 ± 0.14 nm and slightly improved stability. The half-life of ACNs-DG is improved 24.5-fold and had the highest complexation energy (-50.63/49.15) kcal/mol, indicating hydrogen bonds and π-π stacking forces enhance stability. These findings offer a new perspective for anthocyanin utilisation as a blue colourant and contribute to the large-scale application of LR.
