Also known as MK-991, 1-[(4R,5S)-5-[(2-Aminoethyl)amino]-N(2)-(10,12-dimethyl-1-oxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine]-pneumocandin b0, (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, L-743872
Caspofungin (INN; brand name Cancidas) is a lipopeptide antifungal drug from Merck & Co., Inc. It is a member of a class of antifungals termed the echinocandins. It works by inhibiting the enzyme (1→3)-β-D-glucan synthase and thereby disturbing the integrity of the fungal cell wall.
