RS-87337	Others Sodium Channel Potassium Channel	Cardiovascular Disease Inflammation/Immunology
RS-87337 is an orally active piperazine-amidine hybrid class Ia (inhibiting V_max, IC₅₀ = 17 μM)/class III (prolonging ADP90, EC₁₅ = 2 μM) antiarrhythmic agent with selectivity for ventricular conduction . RS-87337 inhibits cardiac sodium channel, thereby reducing the maximum depolarization rate of action potential, with moderate onset and recovery kinetics. RS-87337 reduces cardiac outward potassium conductance (I_K), thus prolonging action potential duration. RS-87337 is applicable to research related to arrhythmia, ventricular arrhythmia, ventricular fibrillation, and myocardial ischemia-reperfusion injury .

AHR 10718	Sodium Channel	Cardiovascular Disease
AHR 10718 is an antiarrhythmic agent that suppresses cardiac arrhythmias induced by digitalis intoxication and myocardial infarction in the intact dog. AHR 10718 also depresses membrane responsiveness and conduction, shortens the effective refractory period of specialized conducting fibers less than action potential duration .

UR 8225	Potassium Channel Calcium Channel	Cardiovascular Disease Inflammation/Immunology
UR 8225 is an orally active ATP-sensitive K ⁺ channel activator with vasodilator, smooth muscle relaxant, antihypertensive, and bronchodilator activities. UR 8225 induces membrane hyperpolarization by increasing outward K ⁺ conductance and reduces Ca ²⁺ influx through voltage-gated L-type Ca ²⁺ channels. UR 8225 reduces total peripheral vascular resistance, shortens cardiac action potential duration, inhibits agonist-induced Ca ²⁺ influx, and stimulates renin release. UR 8225 induces reflex tachycardia but lacks β-adrenergic receptor blocking activity. UR 8225 is widely applicable to research in fields related to hypertension, myocardial ischemia, ventricular fibrillation, and other conditions .

Sodium Channel Blocker Library	191 compounds
Sodium channels conduct sodium ions (Na+) through a cell's plasma membrane that are the source of excitatory currents for the nervous system and muscle. Na channels are classified according to the trigger that opens the channel for such ions, i.e. either a voltage-change (Voltage-gated, voltage-sensitive, or voltage-dependent sodium channel also called VGSCs or Nav channel) or a binding of a substance (a ligand) to the channel (ligand-gated sodium channels). Dysfunction in voltage-gated sodium channels correlates with neurological and cardiac diseases, including epilepsy, myopathies, pain and cardiac arrhythmias. Sodium channel blockers are used in the treatment of cardiac arrhythmia, pain and convulsion. MCE offers a unique collection of 191 sodium channel blocker and antagonists, all of which have the identified inhibitory effect on sodium channels. MCE Sodium Channel Blocker Library can be used for neurological and cardiac diseases drug discovery and sodium channel research.

Amino Acid Metabolite Compound Library	200 compounds
Amino acids are the fundamental components that sustain life activities, playing roles in ATP generation, promoting nucleotide synthesis, and maintaining cellular redox balance. Moreover, dysregulation of amino acid consumption is a significant potential regulatory mechanism leading to impaired anti-tumor immunity in immune cells. The normal functioning of immune cells relies on amino acid metabolic pathways to obtain energy and materials, and upon activation, they reprogram their metabolism to support growth, proliferation, and effector functions. Additionally, metabolic disorders of specific amino acids (such as branched-chain amino acids, glutamine, and arginine) can exacerbate mitochondrial dysfunction and oxidative stress, thereby promoting myocardial fibrosis and cardiac cell damage. Therefore, conducting research related to amino acid metabolism holds promise for discovering potential drugs for diseases related to cancer, immunity, and metabolism. MCE can provide 200 kinds of metabolites of amino acid metabolic pathways, which can be used for drug screening in various diseases such as cancer, immune disorders, metabolic diseases, mitochondrial-targeted diseases
