Description: Echinocandin B is a novel and potent cyclic hexapeptide echinocandin antibiotic originally isolated from Aspergillus nidulans var. echinulatus with specific anti-yeast activity. It inhibits beta-1,3-glucan synthesis and thus attacks the cell wall of fungi. Echinocandin B is an inhibitor of 1,3-β glucan synthase, and it inhibits incorporation of radiolabeled glucose into alkali-insoluble glucan by S. cerevisiae spheroplasts in a dose-dependent manner. It inhibits growth of C. albicans in vitro with an MIC value of 3.9 µg/ml after 2 days.

Step Two: Enter the in vivo formulation
%DMSO + % + %Tween 80 + %ddH2O
Calculation Results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid concentration mg/mL) ,Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
