Pneumocandin B0 is a lipopeptide natural product and a selective inhibitor of fungal 1,3-β-D-glucan synthase. By inhibiting glucan synthesis, it disrupts the structural integrity of the fungal cell wall, resulting in osmotic instability and fungal cell lysis. It serves as an essential precursor and intermediate in the semi-synthesis of echinocandin antifungal agents, such as caspofungin. [1]

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).
