Article Synopsis
  • The study aimed to evaluate the effectiveness of combining levofloxacin with G-CSF against using G-CSF alone in preventing infections following autologous stem cell transplants (ASCT) in patients with blood cancers.
  • A retrospective analysis of 102 patients was conducted to compare the rates of febrile neutropenia, bacterial infections, hospital stay lengths, costs, and post-transplant survival between the two treatment groups (levofloxacin+G-CSF vs. G-CSF only).
  • Results showed no significant difference in infection rates or hospitalization metrics between the two groups, suggesting that adding levofloxacin may not provide additional benefits in preventing infections during ASCT.

The integration of fluorine atoms into biologically active organic compounds has proved to be a vital technique in small molecule drugs. This technique can substantially enhance crucial properties, including metabolic stability, lipophilicity, and bioavailability, often with a mere addition of a single fluorine atom or a trifluoromethyl group. Over the past few decades, this concept has also been applied in nucleic acid chemistry.

Although small interfering RNA (siRNA) is a key player among gene inhibition therapeutics, there are many obstacles to the development of siRNA drugs due to inherent properties of oligonucleotides, including the unsatisfactory stability of unmodified siRNA, poor pharmacokinetic distribution, and the toxicity induced by off-target effects. To maximize treatment potency, chemical modification of siRNA has undoubtedly been the most successful strategy by far. Widely applied modifications include phosphorothioate linkages, 2'-O-methyl modifications, and 2'-fluoro modifications, among others.
