Sema

Sema is a catalog name for a GLP-1 receptor agonist analogue of human GLP-1(7–37), used in the literature as a laboratory tool for GLP-1 receptor signalling.

Medicinal-chemistry descriptions of this analogue include an aminoisobutyric acid substitution associated with resistance to DPP-4 cleavage, an arginine substitution, and a fatty-diacid chain on a lysine that increases albumin affinity. Lau et al., Journal of Medicinal Chemistry, 2015 (PMID 26308095) report the receptor-binding and in-vitro profile that research catalogs point at when they use this name. How to read that kind of figure is covered under receptor-binding papers.

Sema is not Terz and not GLP-3R. Identity and purity for a given vial are on the certificate of analysis.

The paper is a reference for what the name means in laboratory writing. It is not a set of instructions, and this note is not medical advice.

  1. GLP-3R

    GLP-3R is a catalog name for a fatty-acylated research peptide that chemistry papers describe as a single-chain agonist at the glucagon, GIP, and GLP-1 receptors, listed for laboratory supply at https://onesourcepeptides.com/product/one-source-g3r.

  2. Terz

    Terz is a catalog name for a synthetic, fatty-diacid-acylated peptide studied as a dual agonist of the GIP and GLP-1 receptors.

  3. BPC-157

    BPC-157 is a synthetic 15-residue peptide, sequence GEPPPGKPADDAGLV, taken from a gastric protein fragment, the published work on it is preclinical, and the research catalog lists it at https://onesourcepeptides.com/product/bpc-157.
