Anti-Parkinson's Disease Compound Library

2,085 compounds

Parkinson’s disease (PD), the second most common age-associated neurodegenerative disorder, is characterized by the loss of dopaminergic (DA) neurons and the presence of α-synuclein-containing aggregates in the substantia nigra pars compacta (SNpc). Motor features such as tremor, rigidity, bradykinesia and postural instability are common traits of PD. To date, there is no treatment to stop or at least slow down the progression of the disease. The etiology and pathogenesis of PD is still elusive, however, a large body of evidence suggests a prominent role of oxidative stress, inflammation, apoptosis, mitochondrial dysfunction and proteasome dysfunction in the pathogenesis of PD.

MCE offers a unique collection of 2,085 compounds with anti- Parkinson’s Disease activities or targeting the unique targets of PD. MCE Anti- Parkinson's Disease Compound Library is a useful tool for exploring the mechanism of PD and discovering new drugs for PD.

Neurodegenerative Disease-related Compound Library

3,545 compounds

Neurodegenerative diseases are incurable and life-threatening conditions that result in progressive degeneration and/or death of nerve cells. Some common neurodegenerative diseases include Alzheimer’s Disease (AD), Parkinson’s Disease (PD), Motor Neuron Disease (MND), Huntington’s Disease (HD), Spino-Cerebellar Ataxia (SCA), Spinal Muscular Atrophy (SMA), and Amyotrophic Lateral Sclerosis (ALS). Because the pathophysiology of neurodegenerative disorders is generally poorly understood, it is difficult to identify promising molecular targets and validate them. At the same time, about 85% of the drugs fail in clinical trials. Therefore, validating new targets and discovering new drugs to mitigate neurodegenerative disorders is need of the hour.

MCE offers a unique collection of 3,545 compounds with anti-Neurodegenerative Diseases activities or targeting the unique targets of neurodegenerative diseases. MCE Neurodegenerative Disease-related Compound Library is a useful tool for exploring the mechanism of neurodegenerative diseases and discovering new drugs for neurodegenerative diseases.

L&M-D-MR

Fluorescent Dyes

L&M-D-MR is a highly specific fluorescent "AND" logic probe with response moieties for leucine aminopeptidase (LAP) and monoamine oxidase (MAO). The coexistence of both LAP and MAO is required for L&M-D-MR to trigger intramolecular cyclization, release fluorophores and activate fluorescence. In the presence of only a single enzyme, L&M-D-MR generates only an extremely weak signal. L&M-D-MR enables bioimaging in living cells and mouse models, and can effectively distinguish different subtypes of liver diseases via blood samples or test strips. L&M-D-MR is widely used in studies related to liver cirrhosis, hepatitis B and drug-induced liver injury .
