Biological target:
OP-1118 is a major metabolite of Fidaxomicin.
In vitro activity:
This study used fresh human colonic explants, NCM460 human colonic epithelial cells, and RAW264.7 mouse macrophages to study the mechanism of the activity of fidaxomicin and OP-1118 against toxin A- and B-mediated cytokine expression and apoptosis. Fidaxomicin and OP-1118 dose-dependently inhibited toxin A- and B-induced TNF-α and interleukin-1β (IL-1β) mRNA expression and histological damage in human colonic explants. Fidaxomicin and OP-1118 inhibited toxin A-mediated NF-κB phosphorylation in human and mouse intestinal mucosae. Fidaxomicin and OP-1118 also inhibited toxin A-mediated NF-κB phosphorylation and TNF-α expression in macrophages, which was reversed by the NF-κB activator phorbol myristate acetate (PMA). Reference: Antimicrob Agents Chemother. 2017 Dec 21;62(1):e01513-17. https://pubmed.ncbi.nlm.nih.gov/29038278/
In vivo activity:
Based on the in vitro cytotoxicity and the responses of inhibiting the Notch signaling, the antitumor efficacy of fidaxomicin in 4T1-tumor-bearing mice was then evaluated. Fidaxomicin demonstrated potent anti-cancer activity, yielding 62.56% and 83.19% inhibitory efficacies on the growth of tumors at 25 and 25 mg/kg, respectively (Figure 9c). The average tumor weight of mice treated with fidaxomicin was significantly lower than that of mice treated with DAPT or 5-fluorouracil at a dose of 25 mg/kg, indicating the greatest anti-tumor ability among the three treatment groups.
