Synthesis of Novel C‐Acyl‐Glycosyl Sulfonamides via Pd‐Catalyzed Carbonylative Coupling

European Journal of Organic Chemistry, EarlyView.
A Pd‐catalyzed carbonylative coupling of 1‐iodo‐glycals with diverse sulfonamides using Mo(CO)6 enables efficient access to C‐acyl‐glycosyl sulfonamides.This robust and versatile strategy delivers novel glycoside derivatives in good to excellent yields, highlighting their potential for drug discovery.

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Functional and physicochemical properties of proteins isolated from four different pulses

Food Biomacromolecules, EarlyView.
Proteins from four pulses viz. pinto bean, cow pea, pigeon pea, and navy bean were isolated and characterized. Pinto bean protein showed the highest oil absorption capacity and solubility. Pinto bean protein exhibited the highest emulsion capacity and foaming capacity. Cow pea protein showed the highest in vitro protein digestibility.

Memory of Chirality in Radical Addition–Translocation–Cyclization Cascades

Helvetica Chimica Acta, EarlyView.
Radical addition–translocation–cyclization cascades of chiral alkynes show striking memory of chirality (MoC), with strong retention of configuration when fast, polarity favored cyclization are involved. The most effective system employs a highly electron‐poor pentafluorobenzenesulfonyl group.

A Morphological Study of Restoration of Damaged Hair Fiber With Chemical Treatments Using Microscopy Techniques

Microscopy Research and Technique, EarlyView.
Assessment of Restoring Chemically Damaged Hair Fibers Using Microscopy and Spectroscopy. ABSTRACT This paper analyses hair restoration products currently on the market that treat chemically processed hair. This study measured the restoration of structural integrity in hair samples from both chemically damaged hair (chemically relaxed, bleached, and ...

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character

Macromolecular Rapid Communications, EarlyView.
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Synthesis of Telechelic‐Type Polypeptides Functionalized with Aromatic Units and the Characterization of Their Structures and Thermal Properties

Macromolecular Rapid Communications, EarlyView.
Polypeptide chains were extended from both ends of aromatic diamines by chemoenzymatic polymerization, resulting in the synthesis of telechelic polyglycines (TPG) and polyalanines (TPA). These telechelic polymers assembled into branched nanofibrils through π‐π stacking of aromatic rings, with the polymer backbones bent at the aromatic unit.
