Intestinal Barrier Glycosylation for Gut Physiology and Pathology

open access: yesBarrier Immunity, EarlyView.
ABSTRACT The intestinal barrier is a selective structure that safeguards the body from external threats while permitting nutrient absorption and immune surveillance. It consists of the outer mucus layer, the intermediate layer of intestinal epithelial cells (IECs), and the inner layer of immune cells. The proteins in the mucus layer and within IECs are

Green Synthesis of Hantzsch Dihydropyridines from Biorenewable Furans Derived from Lignocellulosic Biomass

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A sustainable methodology is developed for the synthesis of dihydropyridines from furanic aldehydes derived from lignocellulosic biomass, using p‐sulfonic calix[4]arene as a catalyst and microwave irradiation heating. The reaction occurs in the absence of solvents, with short reaction time and satisfactory yields.

Toward the Synthesis of 3,3‐Difluoro Deaminated Sialic Acid (C3DFKDN)

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The synthesis of protected C3‐difluoro KDN (C3DFKDN), an unnatural derivative of the sialic acid member, KDN, and key building block for KDN‐based chemical probes, is reported. Its 12‐step synthetic route starts from commercially available methyl d‐mannopyranoside and key steps include a Reformatsky reaction with ethyl bromodifluoroacetate, alkylation ...
