Caspofungin Acetate Application
Uses : Caspofungin acetate is a semi-synthetic analogue of pneumocandin B0 with improved water solubility, a significant limitation in the development of the echinocandin class as pharmaceuticals. Caspofungin acetate acts by inhibiting the synthesis of β-(1,3)-D-glucan, an essential component of the cell wall of susceptible fungi.
Uses: Calcium antagonist, coronary vasodilator, anti-inflammatory, analgesic
