Synthesis of a Glycosylphosphatidylinositol (GPI) Fragment as a Potential Substrate for Mannoprotein Transglycosidases
Belz, Tyson F.,Williams, Spencer J.
, p. 2053 - 2058 (2021/08/31)
A glycophosphatidylinositol tetrasaccharide fragment was synthesized to mimic the core features of primary model, that of Saccharomyces cerevisiae. The salient feature of this approach is centered on the quick access to various α-1,2- and α-1,6-mannosyl a

Naturally occurring spirostanol saponins bear a chacotriose, α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→4)] -β-d-glucopyranose residue as the oligosaccharide moiety which is believed to be important for biological activity. Herein the development of a concise, combinatorial method for the synthesis of two series of glycan variants at the 2′ and/or 4′ positions of chacotriose is described and the structure-activity relationships of the glycone part at 3-OH of chlorogenin investigated. These compounds were found to be weakly-cytotoxic toward leukemia cell lines CCRF and HL-20, indicating that the chacotriose moiety is important for anticancer activity.
Unexpected stereocontrolled access to 1α,1′β-disaccharides from methyl 1,2-ortho esters
Uriel, Clara,Ventura, Juan,Gomez, Ana M.,Lopez, J. Cristobal,Fraser-Reid, Bert
experimental part, p. 795 - 800 (2012/03/22)
Mannopyranose-derived methyl 1,2-orthoacetates (R = Me) and 1,2-orthobenzoates (R = Ph) undergo stereoselective formation of 1α,1′β-disaccharides, upon treatment with BF 3?Et2O in CH2Cl2, rather than the expected acid-catalyzed reaction leading to methyl glycosides by way of a rearrangement-glycosylation process of the liberated methanol.
Mitochondrial affinity of guanidine-rich molecular transporters built on monosaccharide scaffolds: Stereochemistry and lipophilicity
Lee, Woo Sirl,Kim, Wanil,Kim, Kyong-Tai,Chung, Sung-Kee
experimental part, p. 2286 - 2300 (2012/06/16)
We synthesized eight G8 molecular transporters (MTs) based on 4 different monosaccharide scaffolds, and studied their biological properties with a special focus on possible mitochondrial targeting and tissue selectivity. The mitochondrial affinity of these MTs was found to be clearly related to the scaffold stereochemistry and also tenuously with the lipophilicity. It may be suggested that in the practical delivery strategy of drugs for the brain and mitochondrial diseases the BBB permeability and mitochondrial affinity should be considered as key parameters, and that an enhanced mitochondrial affinity appears possible by further research on the structure-property relationship of guanidine-rich molecular transporters.
Synthesis and cytotoxicity evaluation of natural α-bisabolol β-d-fucopyranoside and analogues
Piochon, Marianne,Legault, Jean,Gauthier, Charles,Pichette, Andre
experimental part, p. 228 - 236 (2009/09/05)
α-Bisabolol β-d-fucopyranoside, a cytotoxic naturally occurring compound, was efficiently synthesized along with five other α-bisabolol glycosides (β-d-glucoside, β-d-galactoside, α-d-mannoside, β-d-xyloside and α-l-rhamnoside). Glycosidation of α-bisabol
