Article Synopsis
  • Gemcitabine (GEM) is widely used to treat solid tumors, but its effectiveness is limited by rapid metabolism into an inactive form (dFdU) by the enzyme cytidine deaminase (CDA), which decreases its oral bioavailability.
  • Cedazuridine (CDZ) has been identified as a potent inhibitor of CDA, and when combined with GEM, it may enhance GEM's oral bioavailability.
  • A study using HPLC-MS/MS confirmed that CDZ significantly improved GEM's bioavailability in mice by inhibiting its metabolism, suggesting potential benefits for clinical applications of the GEM-CDZ combination.

The treatment time window for acute cerebral infarction in global guidelines is within 24 h. We report a patient who was admitted to the hospital and underwent endovascular treatment reaching 40 h. During vascular examination, the thrombus moved to distant segment, and then the surgeon quickly performed endovascular treatment.

The non-selective cytotoxicity of toxins limits the clinical relevance of the toxins. In recent years, toxins have been widely used as warheads for antibody‒drug conjugates (ADCs) due to their efficient killing activity against various cancer cells. Although ADCs confer certain targeting properties to the toxins, low drug loading capacity, possible immunogenicity, and other drawbacks also limit the potential application of ADCs.

Cholestasis is a common liver injury without any effective therapeutic drugs so far. Resveratrol (RES) and luteolin (LUT) are natural polyphenols that exert protective effects on multiple liver injuries. Coadministration of RES and LUT could significantly improve the bioavailability of LUT and increase the systemic exposure to RES, and the combined treatment could also benefit from their multi-component and multi-target characteristics.

Both luteolin (LUT) and resveratrol (RES) are natural polyphenols that exert therapeutic effects on liver injuries. Extensive glucuronidation by uridine diphosphate-glucuronosyltransferases 1As (UGT1As) results in poor bioavailability of LUT, which limits its clinical application. As an inhibitor of UGT1A1 and UGT1A9, RES may affect the bioavailability of LUT.
