(4R,5S)-5-((2-aminoethyl)amino)-N(2)-(10,12-dimethyltetradecanoyl)-4-hydroxy-L-ornithyl-L-threonyl-trans-4-hydroxy-L-prolyl-(S)-4-hydroxy-4-(p-hydroxyphenyl)-L-threonyl-threo-3-hydroxy-L-ornithyl-trans-3-hydroxy-L-proline cyclic (6-1)-peptide
Caspofungin is a semisynthetic cyclic hexapeptide echinocandin antibiotic which exerts its effect by inhibiting the synthesis of 1,3-beta-D-glucan, an integral component of the fungal cell wall. It has a role as an antiinfective agent. It is a homodetic cyclic peptide, an echinocandin, a semisynthetic derivative and an antibiotic antifungal drug. It is functionally related to a pneumocandin B0.
