TG103 is an experimental GLP-1 receptor agonist and Fc fusion protein combination, developed by CSPC Pharmaceutical Group. [1]
Glucagon-like peptide-1 (GLP-1) is a 30- or 31-amino-acid-long peptide hormone deriving from the tissue-specific posttranslational processing of the proglucagon peptide. It is produced and secreted by intestinal enteroendocrine L-cells and certain neurons within the nucleus of the solitary tract in the brainstem upon food consumption. The initial product GLP-1 (1–37) is susceptible to amidation and proteolytic cleavage, which gives rise to the two truncated and equipotent biologically active forms, GLP-1 (7–36) amide and GLP-1 (7–37). Active GLP-1 protein secondary structure includes two α-helices from amino acid position 13–20 and 24–35 separated by a linker region.
The glucagon-like peptide-1 receptor (GLP1R) is a G protein-coupled receptor (GPCR) found on beta cells of the pancreas and on neurons of the brain. It is involved in the control of blood sugar level by enhancing insulin secretion. In humans it is synthesised by the gene GLP1R, which is present on chromosome 6. It is a member of the glucagon receptor family of GPCRs. GLP1R is composed of two domains, one extracellular (ECD) that binds the C-terminal helix of GLP-1, and one transmembrane (TMD) domain that binds the N-terminal region of GLP-1. In the TMD domain there is a fulcrum of polar residues that regulates the biased signaling of the receptor while the transmembrane helical boundaries and extracellular surface are a trigger for biased agonism.
Xiaodong Wang is a Chinese-American biochemist best known for his work with apoptosis, one of the ways through which cells kill themselves.
Glucagon-like peptide-2 receptor (GLP-2R) is a protein that in human is encoded by the GLP2R gene located on chromosome 17.
Homeobox protein MSX-2 is a protein that in humans is encoded by the MSX2 gene.
ERG is an oncogene. ERG is a member of the ETS family of transcription factors. The ERG gene encodes for a protein, also called ERG, that functions as a transcriptional regulator. Genes in the ETS family regulate embryonic development, cell proliferation, differentiation, angiogenesis, inflammation, and apoptosis.
Growth factor, augmenter of liver regeneration , also known as GFER, or Hepatopoietin is a protein which in humans is encoded by the GFER gene. This gene is also known as essential for respiration and vegatative growth, augmenter of liver regeneration, and growth factor of Erv1-like/Hepatic regenerative stimulation substance.
Serine/threonine-protein kinase PCTAIRE-1 is an enzyme that in humans is encoded by the PCTK1 gene.
Omacetaxine mepesuccinate, formerly named as homoharringtonine or HHT, is a pharmaceutical drug substance that is indicated for treatment of chronic myeloid leukemia (CML).
Renalase, FAD-dependent amine oxidase is an enzyme that in humans is encoded by the RNLS gene. Renalase is a flavin adenine dinucleotide-dependent amine oxidase that is secreted into the blood from the kidney.
Homeobox protein DBX2, also known as developing brain homeobox protein 2, is a protein that in humans is encoded by the DBX2 gene. DBX2 plays an important role in the development of the central nervous system, specifically in the development of the neural tube and brain. DBX2 is located on chromosome 12 and is approximately 36,000 base pairs long. DBX2 is predicted to enable DNA-binding transcription activity as well as being involved in the regulation of transcription by RNA polymerase II.
Euchromatic histone-lysine N-methyltransferase 1, also known as G9a-like protein (GLP), is a protein that in humans is encoded by the EHMT1 gene.
Geniposide, the glycoside form of genipin, is a bioactive iridoid glycoside that is found in a wide variety of medicinal herbs, such as Gardenia jasminoides (fruits) . Geniposide shows several pharmacological effects including neuroprotective, antidiabetic, hepatoprotective, anti-inflammatory, analgesic, antidepressant-like, cardioprotective, antioxidant, immune-regulatory, antithrombotic and antitumoral activity. These pharmacology benefits arise through the modulating action of geniposide on several proteins and genes that are associated with inflammatory and oxidative stress processes.
Cymegesolate, also known as cypionyl megestrol acetate or as megestrol acetate 3β-cypionate, is a progestin medication which was never marketed. It was developed in China in the late 1970s and early to mid 1980s for use as a hormonal contraceptive. The medication was formulated at a dose of 50–100 mg in combination with a "trace" dose of 0.25–0.5 mg quinestrol as a long-lasting, once-a-month combined oral contraceptive pill. This combination has been studied in 1,213 women across a total of 9,651 menstrual cycles, with contraceptive effectiveness of over 99.13% and "very few side effects." At the high dose, it showed an anovulation rate of only about 60%, and instead mediated its contraceptive effects via a marked anti-implantation effect.
Conbercept, sold under the commercial name Lumitin, is a novel vascular endothelial growth factor (VEGF) inhibitor used to treat neovascular age-related macular degeneration (AMD) and diabetic macular edema (DME). The anti-VEGF was approved for the treatment of neovascular AMD by the China State FDA (CFDA) in December 2013. As of December 2020, conbercept is undergoing phase III clinical trials through the U.S. Food and Drug Administration’s PANDA-1 and PANDA-2 development programs.
Peptide therapeutics are peptides or polypeptides which are used to for the treatment of diseases. Naturally occurring peptides may serve as hormones, growth factors, neurotransmitters, ion channel ligands, and anti-infectives; peptide therapeutics mimic such functions. Peptide Therapeutics are seen as relatively safe and well-tolerated as peptides can be metabolized by the body.
V-01 is a protein subunit COVID-19 vaccine candidate developed by a subsidiary of Livzon Pharmaceutical Group Inc.
Ecnoglutide (XW003) is a GLP-1 agonist being developed for the treatment of obesity and type 2 diabetes. In preclinical trials, "Ecnoglutide showed a favorable potency, pharmacokinetic, and tolerability profile, as well as a simplified manufacturing process" compared to other GLP-1 agonists.
Fotagliptin (SAL067) is a DPP-4 inhibitor under development for the treatment of type 2 diabetes. Like other DPP-4 inhibitors, it works by increasing endogenously produced GLP-1 and GIP. In a phase 3 trial it showed similar results as alogliptin.
HS-10365 is a RET tyrosine kinase inhibitor developed for non-small cell lung cancer by Hansen Pharmaceutical.
