Lucinactant is a new synthetic peptide-containing surfactant for intratracheal use. It contains sinapultide, a novel, hydrophobic, 21-amino acid peptide (leucine and lysine repeating units, KL4 peptide) designed to mimic human surfactant protein-B (SB-P). Mor…

Sinapultide (also known as KL4 peptide) is a synthetic protein used to mimic human lung surfactant protein B.[L2502] This protein has a weight of 2469.40.[L2502] Sinapultide is a 21-residue peptide made up of lysine (K) and leucine (L) residues with the se…
