Compound information

Tesamorelin research data.

Synthetic 44-residue GHRH(1-44) analogue with an N-terminal trans-3-hexenoyl group

Tesamorelin is a synthetic 44-residue peptide amide. Its amino-acid sequence is the full human 1-44 GHRH sequence, and its single structural modification is a trans-3-hexenoyl group acylating the N-terminal tyrosine. The compound was developed under the code TH9507. With a molecular formula of C221H366N72O67S and an average mass near 5136 Da, it is one of the larger peptides in the Vortex catalogue.

Published work spans peptide chemistry, pharmacology and analytical-method papers. The references below are analytical-chemistry papers: antibody-based purification, solid-phase extraction and liquid chromatography-high-resolution mass spectrometry methods that include tesamorelin among their target peptides in plasma and urine matrices, with validated detection limits, extraction yield and precision. Methods of this kind confirm the identity of a 44-residue peptide by intact mass and fragment ions.
