Disease markers

Estradiol (β-Estradiol) is a steroid hormone and the major female sex hormone. Estradiol can up-regulate the expression of neural markers of human endometrial stem cells (hEnSCs) and promote their neural differentiation. Estradiol can be used for the research of cancers, neurodegenerative diseases and neural tissue engineering.

L-Ascorbic acid (L-Ascorbate), an electron donor, is an endogenous antioxidant agent. L-Ascorbic acid inhibits selectively Ca_v3.2 channels with an IC₅₀ of 6.5 μM. L-Ascorbic acid is also a collagen deposition enhancer and an elastogenesis inhibitor. L-Ascorbic acid exhibits anti-cancer effects through the generation of reactive oxygen species (ROS) and selective damage to cancer cells.

Quercetin, a natural flavonoid, is a stimulator of recombinant SIRT1 and also a PI3K inhibitor with IC₅₀ of 2.4 μM, 3.0 μM and 5.4 μM for PI3K γ, PI3K δ and PI3K β, respectively.

Prostaglandin E2 (PGE2) is a hormone-like substance that participate in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation.

Biotin, vitamin B7 and serves as a coenzyme for five carboxylases in humans, involved in the synthesis of fatty acids, isoleucine, and valine, and in gluconeogenesis. Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids.

Fosribnicotinamide (β-nicotinamide mononucleotide) is a product of the nicotinamide phosphoribosyltransferase (NAMPT) reaction and a key NAD⁺ intermediate. The pharmacological activities of Fosribnicotinamide include its role in cellular biochemical functions, cardioprotection, diabetes, Alzheimer's disease, and complications associated with obesity.

Docosahexaenoic Acid (DHA) is an omega-3 fatty acid abundantly present brain and retina. It can be obtained directly from fish oil and maternal milk.

Melatonin is a hormone made by the pineal gland that can activate melatonin receptor and inhibit PANoptosis. Melatonin plays a role in sleep and possesses important antioxidative and anti-inflammatory properties. Melatonin is a novel selective ATF-6 inhibitor and induces human hepatoma cell apoptosis through COX-2 downregulation. Melatonin attenuates palmitic acid-induced (HY-N0830) mouse granulosa cells apoptosis via endoplasmic reticulum stress.

Liothyronine is an active form of thyroid hormone. Liothyronine binds to thyroid hormone receptors TRα and TRβ with K_is of 2.33 and 2.29 nM for hTRα and hTRβ, respectively. Liothyronine also binds to PVR and blocks the interaction of TIGIT/PVR.

Thymidine, a specific precursor of deoxyribonucleic acid, is used as a cell synchronizing agent. Thymidine is a DNA synthesis inhibitor that can arrest cell at G1/S boundary, prior to DNA replication.

Progesterone is a steroid hormone that regulates the menstrual cycle and is crucial for pregnancy.

L-Glutamic acid is an excitatory amino acid neurotransmitter that acts as an agonist for all subtypes of glutamate receptors (metabolic rhodophylline, NMDA, and AMPA). L-Glutamic acid has an agonist effect on the release of DA from dopaminergic nerve endings. L-Glutamic acid can be used in the study of neurological diseases. L-Glutamic acid acts at ionotropic and metabotropic glutamate receptors.

Linoleic acid is a common polyunsaturated (PUFA) found in plant-based oils, nuts and seeds. Linoleic acid is a part of membrane phospholipids, and functions as a structural component to maintain a certain level of membrane fluidity of the transdermal water barrier of the epidermis. Linoleic acid induces red blood cells and hemoglobin damage via oxidative mechanism .

Folic acid (Vitamin B9) is a orally active essential nutrient from the B complex group of vitamins. Folic acid shows antidepressant-like effect. Folic acid sodium reduces the risk of neonatal neural tube defects. Folic acid can be used to the research of megaloblastic and macrocytic anemias due to folic deficiency.

L-Lactic acid is a buildiing block which can be used as a precursor for the production of the bioplastic polymer poly-lactic acid. L-Lactic acid has antiproliferative activity.

L-Carnitine ((R)-Carnitine), a highly polar, small zwitterion, is an essential co-factor for the mitochondrial β-oxidation pathway. L-Carnitine functions to transport long chain fatty acyl-CoAs into the mitochondria for degradation by β-oxidation. L-Carnitine is an antioxidant. L-Carnitine can ameliorate metabolic imbalances in many inborn errors of metabolism.

Uridine (β-Uridine) is a nucleoside compound composed of uracil and a ribose ring, which are connected by a β-N1-glycosidic bond.

Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.

L-Glutamine (L-Glutamic acid 5-amide) is a non-essential amino acid present abundantly throughout the body and involved in many metabolic processes. L-Glutamine provides a source of carbons for oxidation in some cells.
