Caspofungin Acetate
Caspofungin acetate (MK-0991; CAS 179463-17-3) is an antifungal lipopeptide compound targeting fungal cell wall synthesis by inhibiting 1,3-β-D-glucan synthase, thereby disrupting structural integrity. This inhibition mechanism leads to the blockage of glucan polymer production essential for fungal growth. In vitro analyses indicate Caspofungin acetate demonstrates antifungal activity against species including Aspergillus fumigatus and several Candida species, with MIC90 values around 0.5 µg/mL for C. albicans and C. parapsilosis, 1.0 µg/mL for C. glabrata and C. tropicalis, and 2.0 µg/mL for C. krusei. Caspofungin is utilized in biomedical research to explore cell wall synthesis pathways, fungal susceptibility tests, and mechanistic antifungal studies.

| Applications | Caspofungin suppressed the synthesis of cell wall β-1,3-glucan, which triggered a compensatory stimulation of chitin synthesis. Caspofungin induced morphological changes in Aspergillus fumigates. Moreover, Treatment with caspofungin induced ChsG-dependent upregulation of chitin synthesis and the formation of chitin-rich microcolonies in Aspergillus fumigates. |
