Design, synthesis, and computational studies of novel imidazo[1,2-]pyrimidine derivatives as potential dual inhibitors of hACE2 and spike protein for blocking SARS-CoV-2 cell entry.

In the present work, a new series of imidazo[1,2-]pyrimidine Schiff base derivatives have been obtained using an easy and conventional synthetic route. The synthesized compounds were spectroscopically characterized using H, C NMR, LC-MS(ESI), and FT-IR techniques. Green metric calculations indicate adherence to several green chemistry principles.

Molecular Modeling Targeting the ACE2 Receptor with 's Active Ingredients for Antiviral Drug Discovery against SARS-CoV-2 Infections.

The emergence of a novel coronavirus that later on rendered a global pandemic, caused desperation within the communities and drove increased interest in exploring medicinal plant-based therapeutics to treat and prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus infections. Many medicinal plants have been reported to have antiviral, anti-inflammatory, and immunomodulatory effects that hinder, cure, or ease the symptoms of COVID-19 infection. This exploratory study seeks to dock the active components of , a natural plant with several pharmacological and biological properties, with the angiotensin-converting enzyme II (ACE2) receptor.

Genetic diversity of rhizobia isolated from nodules of Trigonella foenum-graecum L. (fenugreek) cultivated in Northwestern Morocco.

The present work aimed to characterize rhizobia nodulating Trigonella foenum-graecum L. (fenugreek) cultivated in six different geographical locations in Northwestern Morocco. Forty-seven rhizobial isolates from nodules of Trigonella foenum-graecum were grouped into thirteen clusters using the Rep-PCR technique.

Complete Genome Sequence of a SARS-CoV-2 Strain Sampled in Morocco in May 2020, Obtained Using Sanger Sequencing.

The complete genome sequence of a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strain was obtained. The strain was isolated from a nasopharyngeal swab specimen from a female patient in Rabat, Morocco, with coronavirus disease 2019 (COVID-19). This strain belongs to clade 20A and has 12 mutations and 8 amino acid substitutions compared to the reference strain Wuhan/Hu-1/2019.
