• Deuterated Tetrazole CYP51 Inhibitor: V23 Findings

  2026-08-31

  A 2025 European Journal of Medicinal Chemistry study used triazole-to-tetrazole replacement, deuteration, and carbonyl incorporation to develop new CYP51 inhibitors. The lead compound V23 combined broad antifungal activity, activity against resistant fungi, anti-biofilm effects, low cellular toxicity, and significant in vivo efficacy, while reducing inhibition of human CYP enzymes relative to the parent compound A33.
