5-HT Receptor Compound Library

356 compounds

5-HT receptors, also called Serotonin receptors, are a group of G protein-coupled receptors (GPCRs) and ligand-gated ion channels (LGICs) found in the central and peripheral nervous systems. These receptors are now classified into seven families, 5-HT1–7, comprising a total of 14 structurally and pharmacologically distinct mammalian 5-HT receptor subtypes. The 5-HT receptors influence various biological and neurological processes such as aggression, anxiety, appetite, cognition, learning, memory, mood, nausea, sleep, andthermoregulation. The serotonin receptors are the target of a variety of pharmaceutical drugs, including many antidepressants, antipsychotics, anorectics, antiemetics, gastroprokinetic agents, antimigraine agents, hallucinogens, and entactogens.

MCE 5-HT Receptor Compound Library consists of 356 5-HT receptor inhibitors and activators, which can be used for neuropsychiatric disorders drugs discovery.

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. In Vitro: Docosahexaenoic acid (DHA) is essential for the growth and functional development of the brain in infants. DHA is also required for maintenance of normal brain function in adults. The inclusion of plentiful DHA in the diet improves learning ability and memory . DHA is an essential requirement in every step of brain development like neural cell proliferation, migration, differentiation, synaptogenesis. The multiple double bonds and unique structure allow DHA to impart special membrane characteristics for effective cell signaling. Many development disorders like dyslexia, autism spectrum disorder, attention deficit hyperactivity disorder, schizophrenia etc. are causally related to decreased level of DHA . DHA is a potent RXR ligand inducing robust RXR activation already at low micro molar concentrations. The EC₅₀ for RXRα activation by DHA is about 5-10 μM fatty acid . In Vivo: Docosahexaenoic acid administration over 10 weeks significantly reduces the number of reference memory errors, without affecting the number of working memory errors, and significantly increases the docosahexaenoic acid content and the docosahexaenoic acid/arachidonic acid ratio in both the hippocampus and the cerebral cortex .

1-Aminocyclopropane-1-carboxylic acid	Structural Classification Microorganisms Classification of Application Fields Ketones, Aldehydes, Acids Source classification Metabolic Disease Endogenous metabolite Disease Research Fields	Endogenous Metabolite
1-Aminocyclopropane-1-carboxylic acid is an endogenous metabolite. In the presence of low concentrations (1 μM) of glutamate, 1-Aminocyclopropane-1-carboxylic acid acts as a small molecule agonist of NMDA receptors with an EC50 of 0.7-0.9 μM. At high concentrations (10 μM) of glutamate, 1-Aminocyclopropane-1-carboxylic acid acts as a competitive antagonist of NMDA receptors with an EC50 of 81.6 nM. 1-Aminocyclopropane-1-carboxylic acid exerts neuroprotective activity by moderately activating NMDA receptors to prevent neuronal cell death in ischemic animal models. Additionally, 1-Aminocyclopropane-1-carboxylic acid is an antagonist of NMDA receptors, inducing blood pressure reduction and antioxidant effects in stroke-prone hypertensive rats. 1-Aminocyclopropane-1-carboxylic acid enhances object recognition memory and cognitive flexibility dependent on the prefrontal cortex, but does not affect impulsivity nor exhibit an antipsychotic-like profile. 1-Aminocyclopropane-1-carboxylic acid shows promise for research in the field of neurotoxicity. .

2'-Deoxyuridine (Standard)	Structural Classification Natural Products Immune System Disorder Microorganisms Source classification Disease markers Endogenous metabolite	Endogenous Metabolite Thymidylate Synthase
2'-Deoxyuridine (Standard) is the analytical standard of 2'-Deoxyuridine. This product is intended for research and analytical applications. 2’-deoxyuridine is a brain-penetrant pyrimidines nucleotide that is associated with nervous system diseases. 2'-Deoxyuridine could increase chromosome breakage and results in a decreased thymidylate synthetase activity. 2'-Deoxyuridine is a precursor in the synthesis of Edoxudine (HY-B1011) and also an analogue of 5-ethynyl-2'-deoxyuridine, EdU (HY-118411). 2’-deoxyuridine reduces microglial activation and improve oxidative stress damage by modulating glycolytic metabolism on the Aβ25-35-induced brain injury, which is promising for research of Alzheimer’s disease (AD) . In Vitro:The interaction between the 2-deoxyuridine and the column increases the duration of retention of 2-deoxyuridine . Gradient elution with sodium acetate buffer-ACN eluent on two ZIC-HILIC homemade columns separates 2-deoxyuridine in under 9 min . In Vivo:2'-Deoxyuridine (34.42 ng/mL, gavage, 15 min) passes the blood-brain barrier (BBB) to enter the hippocampus of mice brain . 2'-Deoxyuridine (20 mg/kg, gavage, daily for 4 weeks) improves cognition and memory loss and attenuates the damage to the hippocampus in Aβ25-35-induced mice model .
