Fine-Scale Dietary Polyphenol Intake Is Associated with Systemic and Gastrointestinal Inflammation in Healthy Adults.

Background: Polyphenols are dietary bioactive compounds, many of which have anti-inflammatory properties. However, information on the intake of dietary polyphenols at the class and compound levels and their associations with gastrointestinal (GI) and systemic inflammation is lacking.

Objectives: Estimate dietary polyphenol intake in healthy adults and examine its relationship with GI and systemic inflammation markers.

Subtle structural differences of nucleotide analogs may impact SARS-CoV-2 RNA-dependent RNA polymerase and exoribonuclease activity.

The rapid spread and public health impact of the novel SARS-CoV-2 variants that cause COVID-19 continue to produce major global impacts and social distress. Several vaccines were developed in record time to prevent and limit the spread of the infection, thus playing a pivotal role in controlling the pandemic. Although the repurposing of available drugs attempts to provide therapies of immediate access against COVID-19, there is still a need for developing specific treatments for this disease.

A Longitudinal H NMR-Based Metabolic Profile Analysis of Urine from Hospitalized Premature Newborns Receiving Enteral and Parenteral Nutrition.

Preterm newborns are extremely vulnerable to morbidities, complications, and death. Preterm birth is a global public health problem due to its socioeconomic burden. Nurturing preterm newborns is a critical medical issue because they have limited nutrient stores and it is difficult to establish enteral feeding, which leads to inadequate growth frequently associated with poor neurodevelopmental outcomes.

Chemoinformatic Characterization of Synthetic Screening Libraries Focused on Epigenetic Targets.

The importance of epigenetic drug and probe discovery is on the rise. This is not only paramount to identify and develop therapeutic treatments associated with epigenetic processes but also to understand the underlying epigenetic mechanisms involved in biological processes. To this end, chemical vendors have been developing synthetic compound libraries focused on epigenetic targets to increase the probabilities of identifying promising starting points for drug or probe candidates.

Automatic Identification of Analogue Series from Large Compound Data Sets: Methods and Applications.

Analogue series play a key role in drug discovery. They arise naturally in lead optimization efforts where analogues are explored based on one or a few core structures. However, it is much harder to accurately identify and extract pairs or series of analogue molecules in large compound databases with no predefined core structures.

DiaNat-DB: a molecular database of antidiabetic compounds from medicinal plants.

Natural products are an invaluable source of molecules with a large variety of biological activities. Interest in natural products in drug discovery is documented in an increasing number of publications of bioactive secondary metabolites. Among those, medicinal plants are one of the most studied for this endeavor.

Union is strength: antiviral and anti-inflammatory drugs for COVID-19.

• Treatment for moderately ill COVID-19 patients might arise from drug repurposing. • RdRp, spike protein, and M are relevant SARS-CoV-2 molecular targets. • Targeting human furin may contain viral infection and inflammation.
