Article Synopsis
  • Researchers determined the structures of new compounds called flavacitropones A and B, which are homoacridone-flavanone dimers from the plant species (Sims) Kurz in the Rutaceae family.
  • Flavacitropone A was tested for its biological effects on cytotoxicity and inflammatory markers in a specific rat cell line (RBL-2H3).
  • The results showed that flavacitropone A reduced the release of TNF-α, a pro-inflammatory cytokine, but did not affect histamine release.

In this single-center retrospective observational study, we aimed to evaluate the efficacy and safety of reduced-dose DOACs in 86 consecutive patients with acute pulmonary embolism. Patients were divided into standard-dose and reduced-dose DOACs groups.
