Ordering Information

Biological Activity

Climbazole is an imidazole antifungal agent that targets fungal cytochrome P450 14α-demethylase (CYP51) in the ergosterol biosynthesis pathway. Blockade of CYP51 leads to the depletion of ergosterol and the accumulation of toxic methylated sterol intermediates, disrupting fungal cell membrane integrity and permeability. This inhibition impairs cell membrane function and suppresses fungal growth and proliferation, demonstrating broad-spectrum antifungal activity.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
