专利号:US-2024067694-A1 优先权日:2021-01-04 标 题:Synthesis of teduglutide 发明人:GANGA RAMU VASANTHAKUMAR; PATIL NITIN; SUVARNA DEEPA SHANKAR 权利人:BIOCON LTD 摘要:The present invention provides for novel synthetic approach of solid phase synthesis of peptides with C-terminal Aspartic acid by anchoring the side chain carboxylic group of aspartic acid to the solid support to avoid the formation of various impurities and thus resulting in higher yield and ease the purification process. The present invention further provides the usage of free amino acids and reducing agents as antioxidants in the cleavage cocktail to negate the formation of oxidative impurities formed during the global cleavage and isolation of the peptide from solid support.

专利号:US-5175146-A 优先权日:1989-12-05 标题 :Synthetic calcitonin peptides 发明人:BASAVA CHANNA; HOSTETLER KARL Y 权利人:VICAL INC 摘要:Synthetic hypocalcemic peptides which are similar in biological properties to native calcitonins as clinically useful agents. The peptides comprise analogues of native calcitonins having amino acid substitutions and deletions which act to improve potency, prolong duration of the hormonal effect, enhance receptor binding, and increase oral or nasal bioavailability. The calcitonin peptide analogues are less expensive and more easily synthesized than native calcitonins, and have improved resistance to inactivation or degradation. Methods are provided for the synthesis of these peptides. Also, disclosed are novel cyclic peptides, including calcitonin, having increased stability with respect to proteolysis. Methods for the synthesis of these peptides are provided, comprising converting disulfide cyclic peptides and proteins to enzymatically and chemically stable cyclic peptide structures by the replacement of cysteine residues with dicarboxylic acids and diamino acids. The method is applicable to various naturally occurring peptides, their synthetic analogues or derivatives, and proteins.
