  A visible-light-promoted and copper-catalyzed stereoselective C(sp3)−H glycosylation reaction was developed for the synthesis of a wide variety of C-glycoamino acids and C-glycopeptidomimetics with good yields and excellent stereoselectivity. The mild reaction conditions are compatible with various carbohydrate substrates, as demonstrated with a series of monosaccharides and a disaccharide.

• In(III) triflate-catalyzed detritylation and glycosylation by solvent-free ball milling

  A highly efficient In(III) triflate-assisted method for the detritylation of O-trityl derivatives of carbohydrates, phenols, and alcohols using solvent-free mechanochemical method is described. In the case of carbohydrates, further reaction in the presence of an acceptor sugar leads to highly efficient glycosylation in the same pot resulting in the formation of the desired glycoside-product in very high yields. The method was applied successfully to the synthesis of a combinatorial library of galactose-based (1,6)-linked cyclo-hexa-, hepta-, and octasaccharides on gram scale. (C) 2014 Elsevier Ltd.

• Evaluation of potential Myt1 kinase inhibitors by TR-FRET based binding assay

  In the human cell cycle, the Myt1 kinase is a crucial regulator of the G2/M transition. Because this membrane-associated kinase is hard to obtain and assay, there is a distinct lack of data so far. Here we report the derivatization of a glycoglycerolipid which was shown previously to be active in a Myt1 activity assay. These compounds were tested in a binding assay together with a set of common kinase inhibitors against a full-length Myt1 expressed in a human cell line. Dasatinib exhibited nanomolar affinity whereas broad coverage inhibitors such as sunitinib and staurosporine derivatives did not show any effect. We also carried out docking studies for the most potent compounds allowing further insights into the inhibitor interaction of this kinase. The glycoglycerolipids showed no significant effects in the binding assay, endorsing the idea of a mechanism of action distant from the active site. (C) 2012 Elsevier Masson SAS. All rights reserved.
• Efficient synthesis of (6-deoxy-glycopyranosid-6-yl) sulfone derivatives and their effect on Ca2+-ATPase

  Synthesis of a series of novel (6-deoxy-glycopyranosid-6-yl) sulfone derivatives has been achieved using a general synthetic strategy. Yields were excellent in every case. The synthetic compounds were evaluated for their biological potential against Ca2+-ATPase, an important enzyme involves in tranporting Ca2+ across the cell membranes. (C) 2010 Elsevier Masson SAS.
