Evaluation of genetic variability and relatedness among eight Centaurea species through CAAT-box derived polymorphism (CBDP) and start codon targeted…

2021

Centaurea is a value-ultimate genus of medicinal plants showing high diversification levels, especially within the Mediterranean basin, and is still traditionally recognized as a complicated taxon. So far, few studies utilizing molecular markers have been done on Centaurea spp. towards a better dissection of its phylogeny and accurate assessment of genetic diversity. Here, two functional marker systems, start codon targeted (SCoT) polymorphism and CAAT box-derived polymorphism (CBDP), were implemented to assess the genetic diversity between eight wild Centaurea species in Egypt. Seventeen SCoT and 19 CBDP primers generated 197 and 179 bands, respectively. These primers generated 158 (80.2%)…

Two novel oxetane containing lignans and a new megastigmane from Paronychia arabica and in silico analysis of them as prospective SARS-CoV-2 inhibito…

2021

The chemical characterization of the extract of the aerial parts of Paronychia arabica afforded two oxetane containing lignans, paronychiarabicine A (1) and B (2), and one new megastigmane, paronychiarabicastigmane A (3), alongside a known lignan (4), eight known phenolic compounds (5–12), one known elemene sesquiterpene (13) and one steroid glycoside (14). The chemical structures of the isolated compounds were constructed based upon the HRMS, 1D, and 2D-NMR results. The absolute configurations were established via NOESY experiments as well as experimental and TDDFT-calculated electronic circular dichroism (ECD). Utilizing molecular docking, the binding scores and modes of compounds 1–3 tow…
