| Biological target: | Oseltamivir carboxylate is an active metabolite of oseltamivir phosphate (Tamiflu). |
| In vitro activity: | Human lumbar IVD (n = 8) tissues were isolated for annulus fibrosus (AF) and nucleus pulposus (NP) primary cell cultures, and human tibial and femoral cartilage tissues (n = 8) were isolated for primary chondrocyte cultures. In the oseltamivir-treated groups, cell proliferation decreased in both AF/NP cell and chondrocyte cultures obtained from IVD cartilage tissues. After Western blotting analysis, changes were observed in the protein expressions of HIF-1α, IL-1β, NF-κB, and the NLRP3 inflammasome in both AF/NP cells and chondrocytes. The results were statistically significant (p < 0.05). Reference: Eur Rev Med Pharmacol Sci. 2022 Jul;26(13):4816-4827. https://pubmed.ncbi.nlm.nih.gov/35856374/ |
| In vivo activity: | Immunocompetent mice received intranasal instillation influenza A or PBS followed by orotracheal inoculation with Aspergillus fumigatus 4 days later. Oseltamivir treatment or placebo was started at day 0, day 2, or day 4. Early oseltamivir treatment prevented severe influenza pneumonia and mitigated the development of IPA and associated mortality. A time-dependent treatment effect was consistently observed with imaging, molecular, and pathological analyses.
