Disclosed are methods of isolating linaclotide, a cyclized 14-amino-acid peptide with three disulfide bonds. The sequence consists of Cys-Cys-Glu-Tyr-Cys-Cys-Asn-Pro-Ala-Cys-Thr-Gly-Cys-Tyr with disulfide bridges between the cysteine residues at positions 1 and 6, 2 and 10, and 5 and 13. The drug acts as a GCC superagonist, elevating intracellular cGMP composition for treating various disorders, including gastrointestinal disorders, obesity, congestive heart failure and benign prostatic hyperplasia. |
