Caspofungin(CAT: I013966) is a semi-synthetic analog of pneumocandin B0 with improved water solubility, a significant limitation in the development of the echinocandin class as pharmaceuticals. Caspofungin acts by inhibiting the synthesis of β-(1,3)-D-glucan, an essential component of the cell wall of susceptible fungi.
