Dihydroergotamine-d3 is the d3-labeled Dihydroergotamine (HY-B0670). Dihydroergotamine (DFN-19) is a blood-brain barrier-permeable semi-synthetic ergot alkaloid, acting as a full agonist of 5-HT1B/1D receptors (Ki values of 0.3 nM and 2.5 nM, respectively; functional IC50 values of 2 nM and 2.2 nM, respectively). Dihydroergotamine inhibits Forskolin (HY-15371)-stimulated cAMP accumulation, possesses α-adrenergic receptor antagonistic activity and weak dopaminergic agonistic activity. It mediates intracranial cerebrovascular contraction, inhibits the release of neuropeptides such as CGRP/substance P, and suppresses neurogenic inflammation by activating 5-HT1B/1D receptors in the trigeminovascular system. Dihydroergotamine binds to the catalytic site of Trypanosoma cruzi trypanothione reductase and exhibits trypanocidal activity in vitro. Dihydroergotamine can be used in studies related to migraine and trypanosome infections .

SKF-83566 (Standard) is the analytical standard of SKF-83566 (HY-103430A). This product is intended for research and analytical applications. SKF-83566 is an orally active, blood-brain barrier-permeable D1/D5 dopamine receptor antagonist with a Ki value of approximately 0.4-0.56 nM. SKF-83566 modulates locomotor behavior and spatial memory by blocking D1 receptors and inhibits glioblastoma progression by targeting the DRD1/c-Myc/UHRF1 pathway. SKF-83566 acts as an inhibitor of the dopamine transporter (DAT) and adenylyl cyclase 2 (AC2). SKF-83566 competitively binds to DAT to inhibit dopamine reuptake and non-competitively inhibits AC2 activity, thereby reducing cAMP accumulation. SKF-83566 is used in research areas such as dopaminergic system mechanisms, learning and memory, targeted intervention for glioblastoma, AC2 pathophysiology, antiparasitic drug screening, and synaptic plasticity (the "gating effect") .

α,β-Methylene-ATP trisodium (Standard) is the analytical standard of α,β-Methylene-ATP (trisodium) (HY-108652). This product is intended for research and analytical applications. α,β-Methylene-ATP trisodium is an agonist of P2X1 and P2X3 receptors and can cross the blood-brain barrier. α,β-Methylene-ATP trisodium can trigger a reflex pressor response by activating P2X receptors in peripheral muscles and the central locus coeruleus (LC); this effect can be blocked by the P2X antagonist PPADS (HY-108960). α,β-Methylene-ATP trisodium also activates noradrenergic neurons in the central locus coeruleus, mediating antinociceptive effects; this effect can be attenuated by the locus coeruleus damaging agent DSP-4 (HY-103210/HY-121602). α,β-Methylene-ATP trisodium can be used to study the pathological mechanisms of neuropathic pain, cardiovascular reflex regulation, and antinociceptive effects of the central nervous system .

Withanoside IV binds to amyloid-β 1-42 to inhibit its aggregation, induces neurite outgrowth and synapse reconstruction, repairs damaged axons and dendrites, enhances mitochondrial biogenesis, exerts neuroprotective effects via the BDNF and SIRT1 signaling pathways, reduces ROS production and neuronal apoptosis, and ameliorates memory deficits. Withanoside IV inhibits the activity of the SARS-CoV-2 main protease. Withanoside IV can be used in research related to spinal cord injury, Alzheimer's disease, and coronavirus disease 2019 (COVID-19) .

Synonyms: P-Methoxy-benzyl alcoho; (4-Methoxyphenyl)methanol
4-Methoxybenzyl alcohol (P-Methoxy-benzyl alcoho; (4-Methoxyphenyl) methanol) is a naturally derived volatile aromatic compound. 4-Methoxybenzyl alcohol upregulates the phosphorylation level of PI3K/Akt pathway proteins, downregulates the expression of pro-inflammatory factors, increases the content of tight junction proteins occludin and claudin-5, and alleviates structural damage to the blood-brain barrier. 4-Methoxybenzyl alcohol improves the decrease in viability and NO level of cerebral microvascular endothelial cells induced by oxygen-glucose deprivation/reperfusion, and reduces the release of lactate dehydrogenase. 4-Methoxybenzyl alcohol serves as a substrate in the two-phase persulfate-mediated electro-oxidation system, where it is directionally oxidized to p-anisaldehyde. 4-Methoxybenzyl alcohol acts as a substrate for wild-type fungal aryl alcohol oxidase. 4-Methoxybenzyl alcohol can be used in studies related to ischemic stroke, as well as in research across various fields such as chemical synthesis, including the synthesis of fragrances and flavorings .

Dopamine receptor (DAR), widely distributed in the brain, plays a key role in regulating motor function, motivation, driving force and cognition. The role of DA is mediated by D1-type (D1, D5) and D2-type receptors (D2S, D2L, D3, D4), which are distributed in presynaptic, postsynaptic and extrasynaptic, projection neurons and interneurons. Each receptor has a different function. D1 and D5 receptors couple with G stimulation sites and activate Adenylyl cyclase. The activation of Adenylyl cyclase leads to the production of the second messenger cAMP, which leads to the production of protein kinase A (PKA), which leads to further transcription in the nucleus. D2 to D4 receptors are coupled to G inhibitory sites to inhibit adenylyl cyclase and activate potassium Ion channel. These receptors utilize phosphorylation cascades or direct membrane interactions to affect the functions of voltage-gated and neurotransmitter-gated channels, cytoplasmic enzymes, and transcription factors. Dopamine receptor plays an important role in daily life.

MCE designs a unique collection of 282 small molecules related to dopamine receptor. It is a good tool for screening drugs from nervous system disease.

Synonyms: L-2-Aminopropionic acid (Standard)
L-Alanine (Standard) is the analytical standard of L-Alanine. This product is intended for research and analytical applications. L-Alanine is a non-essential amino acid, involved in sugar and acid metabolism, increases immunity, and provides energy for muscle tissue, brain, and central nervous system. In Vitro: The viability of both hiPSCs, 201B7 cells and ehiPSCs decrease with an increase in L-Alanine concentration, and reach 7.5±1.3% and 3.7±0.7% respectively at 1.2 M of L-Alanine. On the other hand, no decrease in the viability of hFBs and hSkMCs are observed. Although the viability of iCMs slightly decreases along with the increase of the L-Alanine concentration, viability of iCMs at 1.2 M concentration of L-Alanine, 49.4±6.9%, is significantly higher than that of undifferentiated iPSCs, 201B7 cells and ehiPSCs (p< 0.01). The viability of hiPSCs, 201B7 cells and ehiPSCs, drastically decrease even after 2 or 4 h treatment. In contrast, the viability of hFBs fails to decrease at 1, 2, and 4 h and shows a small decrease at 24 h treatment. The viability of 201B7 cells in suspension culture decreases to 11.8±6.0% following treatment with 1.2 M L-Alanine for 2 h, whereas that of hFBs is 72.9±14.2% .
