Gintonin is a glycolipoprotein fraction isolated from ginseng. The non-saponin ingredient was designated as gintonin, where gin was derived from ginseng, ton from the tonic effects of ginseng, and in from protein. The main component of gintonin is a complex of lysophosphatidic acids (LPA) and ginseng proteins such as ginseng major latex-like protein151 (GLP151) and ginseng ribonuclease-like storage protein. [2] [3]
GLP151 is a first plant-derived LPA binding protein as one of Bet v 1 superfamily. GLP151 has a LPA binding domain on H147 and H148 at C-terminal. These two histidine residues bind to phosphate group of LPA and deliver LPA to its cognate receptors to elicit cellular effects such as [Ca2+]i transient and morphological changes. [4]
Lysophospholipid receptors are the high affinity and selective target receptor of gintonin. Gintonin induces [Ca2+]i transient in animal cells. Gintonin also shows in vivo anti-Alzheimer's disease effects through LPA receptor-mediated non-amyloidogenic pathways and enhances cognitive functions in elderly human Alzheimer's disease patients [5] [6] and boosting of hippocampal cholinergic system, [7] hippocampal neurogenesis, [8] anti-depression [9] and in vivo anti-metastatic and anti-atopic dermatitis effects [10] by inhibition of autotaxin activity.

Lysophosphatidic acid (LPA) is a phospholipid derivative that can act as a signaling molecule.
The lysophospholipid receptor (LPL-R) group are members of the G protein-coupled receptor family of integral membrane proteins that are important for lipid signaling. In humans, there are eight LPL receptors, each encoded by a separate gene. These LPL receptor genes are also sometimes referred to as "Edg".
Autotaxin, also known as ectonucleotide pyrophosphatase/phosphodiesterase family member 2, is an enzyme that in humans is encoded by the ENPP2 gene.
Ribose-phosphate diphosphokinase is an enzyme that converts ribose 5-phosphate into phosphoribosyl pyrophosphate (PRPP). It is classified under EC 2.7.6.1.
The nuclear receptor coactivator 1 (NCOA1) is a transcriptional coregulatory protein that contains several nuclear receptor interacting domains and an intrinsic histone acetyltransferase activity. NCOA1 is recruited to DNA promotion sites by ligand-activated nuclear receptors. NCOA1, in turn, acylates histones, which makes downstream DNA more accessible to transcription. Hence, NCOA1 assists nuclear receptors in the upregulation of DNA expression.
Retinoid X receptor alpha (RXR-alpha), also known as NR2B1 is a nuclear receptor that in humans is encoded by the RXRA gene.
B-cell lymphoma 3-encoded protein is a protein that in humans is encoded by the BCL3 gene.
CD99 antigen, also known as MIC2 or single-chain type-1 glycoprotein, is a heavily O-glycosylated transmembrane protein that is encoded by the CD99 gene in humans. The protein has a mass of 32 kD. Unusually for a gene present on the X chromosome, the CD99 gene does not undergo X inactivation, and it was the first such pseudoautosomal gene to be discovered in humans.
Lysophosphatidic acid receptor 1 also known as LPA1 is a protein that in humans is encoded by the LPAR1 gene. LPA1 is a G protein-coupled receptor that binds the lipid signaling molecule lysophosphatidic acid (LPA).
Lysophosphatidic acid receptor 2 also known as LPA2 is a protein that in humans is encoded by the LPAR2 gene. LPA2 is a G protein-coupled receptor that binds the lipid signaling molecule lysophosphatidic acid (LPA).
Lysophosphatidic acid receptor 5 also known as LPA5 is a protein that in humans is encoded by the LPAR5 gene. LPA5 is a G protein-coupled receptor that binds the lipid signaling molecule lysophosphatidic acid (LPA).
Lysophosphatidic acid receptor 3 also known as LPA3 is a protein that in humans is encoded by the LPAR3 gene. LPA3 is a G protein-coupled receptor that binds the lipid signaling molecule lysophosphatidic acid (LPA).
Nuclear receptor coactivator 6 is a protein that in humans is encoded by the NCOA6 gene.
Homeobox protein Hox-A5 is a protein that in humans is encoded by the HOXA5 gene.
Mirodenafil belongs to the drug class PDE5 inhibitors, which includes avanafil, sildenafil, tadalafil, udenafil, and vardenafil, and is the first-line treatment for erectile dysfunction. Developed by SK Chemicals Life Science, mirodenafil is marketed in Korea under the trade name Mvix, offered both as tablets and as orally dissolving film.
Bodhraj Acharya is a Nepalese born American professional, working in the field of laboratory medicine, Cell Biology and chemistry. He has received many honors, grants and travel fellowships in United States and other countries. He has published patents, abstracts and articles in the field. He had worked previously as a clinical laboratory manager at the cardiac hospital in Nepal.
Seong Hoe Park is a Korean immunologist and pathologist and a distinguished professor of pathology at the Seoul National University College of Medicine. He served as the chair of the Department of Pathology (2000–2004), the chair of the Graduate Program of Immunology (2002–2006), the president of Center for Animal Resource Development (2004–2006) at Seoul National University. He was the president of the Korean Association of Immunologists (2000–2001). Throughout his career as a T cell immunologist, Park established the theory of T cell-T cell interaction in human thymus, in which T cells expressing MHC class II drive previously unrecognized types of T cells and provide another significant developmental mechanism of T cells.
Radotinib (INN; trade name Supect), and sometimes referred to by its investigational name IY5511, is a drug for the treatment of different types of cancer, most notably Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) with resistance or intolerance of other Bcr-Abl tyrosine-kinase inhibitors, such as patients resistant or intolerant to imatinib.
Lobeglitazone is an antidiabetic drug in the thiazolidinedione class of drugs. As an agonist for both PPARα and PPARγ, it works as an insulin sensitizer by binding to the PPAR receptors in fat cells and making the cells more responsive to insulin.
HL156A is a derivative of metformin and a potent OXPHOS inhibitor and AMPK activating biguanide. Certain types of cancer cells requires OXPHOS to survive. By targeting it, HL156A might help in improving anticancer therapy. It is more potent than AICAR or metformin at activating AMPK. It is synthesized by Hanall Biopharma.
