Fungi

Pseudomonas aeruginosa (P. Aeruginosa)

Preparation method

This compound is soluble in water. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

10 mg/mL; 24 hrs

Applications

Micafungin decreased the expression of biofilm encoding genes for alginate and pellicles (algC and pelC, respectively).

Animal models

A mouse model of septic Aspergillus fumigatus (A. fumigatus) infection

Dosage form

0.1, 0.32 and 1 mg/kg; s.c.; q.d.

Applications

In a mouse model of septic A. fumigatus infection, Micafungin (0.1 mg/kg) increased the survival rate of mice to 20%. When Micafungin (0.1 mg/kg) was combined with KB425796-C (32 mg/kg), the survival rate of mice increased to 100% in the 31-day post-infection period. For non-treated mice, they survived for only 6 days.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Micafungin is an antifungal agent [1].
Antifungal medicine is a pharmaceutical fungicide used to treat and prevent mycoses such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others.
Micafungin is an antifungal agent known to inhibit 1,3-β-D-glucan synthesis in Candida albicans. In 13 out of 18 P. Aeruginosa isolates tested, micafungin significantly reduced biofilm biomass. In all 9 P. Aeruginosa isolates tested, micafungin decreased the expression of ndvB, which encoded the cell wall 1,3-β-D-glucan. Also, it decreased the expression of biofilm encoding genes for alginate and pellicles (algC and pelC, respectively) [1].
In a mouse model of septic A. fumigatus infection, micafungin (0.1 mg/kg) increased the survival rate of mice to 20%. When micafungin (0.1 mg/kg) combination with KB425796-C (32 mg/kg), the survival rate of mice increased to 100% in the 31-day post-infection period. While non-treated mice survived for only 6 days [2].
