摘要:Abstract(#br)Over the last decade, hair analysis has become a routine procedure in most forensic laboratories and, complementary to blood and urine, hair is a unique biological matrix which gives the opportunity to establish a temporal consumption profile. Despite hair is wi...

摘要:Abstract(#br)The simple addition of mild bases (Et 3 N or DIPEA) allows a high yielding N-transacylation of secondary amides, performed by perfluorinated anhydrides, in molecules that are very sensitive to acids.

摘要:Abstract(#br)Pyridinoline (Pyr), deoxypyridinoline (D-Pyr), galactosyl-pyridinoline (Gal-Pyr) and glucosyl–galactosyl pyridinoline (GluGal-Pyr) are enzymatic mature pyridinium crosslinks. Generally, only total Pyr and D-Pyr urinary amounts (free + bound forms) are evaluated ...

摘要:Abstract(#br)Three homologues of the collagen cross-links deoxypyridinoline, differing in the length of the side chain at the aromatic nitrogen, have been efficiently synthesized as possible internal standards in the quantitative analyses of pyridinolines. The first has a on...

摘要:Abstract(#br)The synthesis of four deuterated sialic acids and their 1,7-lactones has been performed in two ways, one based on sialic acid classical chemistry, and the other involving a direct exchange of the unlabeled acyl group of N -acetylneuraminic acid with a labeled one med...

摘要:Abstract(#br)An efficient protocol for the 4β‐acylamidation of the N ‐acylated glycals of Neu5Ac by using the corresponding N ‐perfluoroacylated congeners as key tools has been developed and applied to the synthesis of glycals combining the features of the molecules wit...

摘要:Abstract(#br)A protocol for direct access to C‐4‐functionalized Neu5Ac2en derivatives by allylic substitution of an α‐acetoxy group with various nucleophiles is reported. The DANA acetamido group is exchanged for a trifluoroacetylamido group (as in FANA) to avoid the fo...

摘要:Abstract(#br)Two simple and rapid procedures affording 4β‐acylamido‐ and 4β‐acetoxyneuraminic acid glycals acylated or perfluoroacylated at the 5‐amino group are reported. The first protocol avoids the formation of oxazolines to synthesize the 4β‐acetamido glycals ...

摘要:Gangliosides, the sialic acid-conjugated glycosphingolipids present in the lipid rafts, have been recognized as important regulators of cell proliferation, migration, and apoptosis. Due to their peculiar localization in the cell membrane, they modulate the activity of severa...
