Inhibition of fungal plant pathogens by synergistic action of chito-oligosaccharides and commercially available fungicides.

open access: yesPLoS ONE, 2014
Chitosan is a linear heteropolymer consisting of β 1,4-linked N-acetyl-D-glucosamine (GlcNAc) and D-glucosamine (GlcN). We have compared the antifungal activity of chitosan with DPn (average degree of polymerization) 206 and FA (fraction of acetylation ...

A Biotechnological Platform Based on the Newly Isolated Streptococcus thermophilus D4 to Obtain Viable Biomass and Exopolysaccharides for Enterocytes Wound Healing

open access: yesBiotechnology and Bioengineering, EarlyView.
Optimizing media for potential probiotic Streptococcus thermophilus biomass and exopolysaccharide production was achieved using design of experiments. This was followed by process development in bioreactors, employing fed‐batch strategies, to increase the production of exopolysaccharide, to test it, after membranes purification, on cells proving the ...

Photo‐Triggered Hyaluronic Acid Hydrogel for 3D Culture and Cell Recovery

open access: yesChemBioChem, EarlyView.
GA: Cross‐linking of hyaluronic acid modified by a strained alkyne with a photosensitive crosslinker terminating in azides gives hydrogels with tuneable mechanical properties. By tuning the wavelength of employed light, the hydrogel can either be fully degraded allowing harvesting of cultured cells or softened resulting in notable changes in cell ...

Functional Analysis of Histidine‐Dependent Self‐Cleaving RNAs Obtained by In Vitro Selection

open access: yesChemBioChem, EarlyView.
Ribozymes can be nucleic acid medicines given their catalytic activity. We attempted to obtain functional RNAs that mimic ribonuclease A catalytic mechanisms. Functional RNAs with high histidine specificity were obtained, suggesting that histidine acts in active structure formation.

Glycosaminoglycans as Polyelectrolytes: Charge, Interactions, and Applications

open access: yesChemBioChem, EarlyView.
Glycosaminoglycans (GAGs) are linear, anionic biopolymers with their functions tightly linked to their charge. This review approaches GAGs from a polyelectrolyte perspective, shedding light on how the distribution of sulfate groups and, thus, negative charges, governs their interactions with other biomolecules.

Síntese e modificações de derivados heterocíclicos de D-arabinose: potenciais inibidores de glicose-6-fosfato isomerase e de glicosamina-6-fosfato sintase Synthesis and modifications of heterocyclic derivatives of D-arabinose: potential inhibitors of glucose-6-phosphate isomerase and glucosamine-6-phosphate synthase

open access: yesQuímica Nova, 2008
The synthesis of -5-(D-arabino-1,2,3,4-tetrahydroxybutyl)tetrazole and -2-(D-arabino-1,2,3,4-tetra-acetoxybutyl)-5-methyl-1,3,4-oxadiazole from D-arabinose is described.

Gold‐Dithiocarbamato Glycoconjugates as Potential Anticancer Agents: Design, Physico‐Chemical Characterization, and In Vitro Biological Activity

open access: yesChemBioChem, EarlyView.
Metal‐dithiocarbamato glycoconjugates based on gold(III), gold(I)‐phosphino, and gold(I)‐carbene scaffolds are here investigated as potential anticancer agents. Contrary to expectations, they induce cell death by acting at the extracellular level rather than targeting overexpressed glucose transporters.

Selective N‐Alkylation of Unprotected Amino Sugars by Alcohols. Application to the Synthesis of Sugar‐Based Surfactants

open access: yesChemistryEurope, EarlyView.
A borrowing hydrogen strategy using an NHC‐Ir(III) catalyst enables selective N‐functionalization of unprotected amino sugars using alcohols as alkylating agents. The use of unprotected substrates avoids extra steps of protection/deprotection, minimizing waste generation.

Finding Drug Candidate Hits With A Hundred Samples: Ultralow Data Screening With Active Learning

open access: yesChemistryEurope, EarlyView.
Ultra‐low‐data hit discovery becomes practical: starting from randomly selected binders, an active‐learning loop selects only 110 molecules from a 100 k library and have a 100% probability of finding 5 or more top‐1% compounds. Noise tests and alternate libraries confirm robustness, enabling single‐researcher campaigns on smaller budgets.
