Parkinson's Disease

Metformin (1,1-Dimethylbiguanide) inhibits the mitochondrial respiratory chain in the liver, leading to AMPK activation and enhancing insulin sensitivity, and can be used in the study of type 2 diabetes. Metformin exerts central glucose-lowering effects by inhibiting Ras-related protein 1 (Rap1) in SF1 hypothalamic neurons. Metformin also inhibits liver oxidative stress, nitrosative stress, inflammation, and apoptosis caused by liver ischemia/reperfusion injury. In addition, Metformin regulates the expression of autophagy-related proteins by activating AMPK and inhibiting the mTOR signaling pathway, thereby inducing tumor cell autophagy and inhibiting the growth of renal cell carcinoma in vitro and in vivo.

CCCP is an oxidative phosphorylation (OXPHOS) uncoupler. CCCP induces activation of PINK1 leading to Parkin Ser65 phosphorylation.

Rotenone is a mitochondrial electron transport chain complex I inhibitor. Rotenone induces apoptosis through enhancing mitochondrial reactive oxygen species production.

Sorafenib (Bay 43-9006) is a potent oral active multikinase inhibitor. Sorafenib blocks autophosphorylation and activity of receptor tyrosine kinases (VEGFR-2, VEGFR-3) and RAF family kinases, thereby suppressing the RAF/MEK/ERK and PI3K/Akt pathways, inhibiting STAT3 phosphorylation, and selectively inhibiting the MAPK pathway in cancer cells. Sorafenib induces cell cycle arrest, autophagy, apoptosis, and PARP cleavage, reduces Bcl-2, Bcl-XL, cyclin D1 levels, and activates Bak and Bax. Sorafenib inhibits tumor growth and metastasis in mouse and rat models. Sorafenib can be used for cancer research, such as colon, breast, non-small-cell lung cancer (NSCLC), ovarian, pancreatic, melanoma, colorectal and hepatocellular carcinoma.

Dasatinib (BMS-354825) is a highly potent, ATP competitive, orally active dual Src/Bcr-Abl inhibitor with potent antitumor activity. The K_is are 16 pM and 30 pM for Src and Bcr-Abl, respectively. Dasatinib inhibits Bcr-Abl and Src with IC₅₀s of <1.0 nM and 0.5 nM, respectively. Dasatinib also induces apoptosis and autophagy, and can cross the blood-brain barrier.

Dizocilpine (MK-801), a potent anticonvulsant, is a selective and non-competitive NMDA receptor antagonist, with a K_d of 37.2 nM in rat brain membranes. Dizocilpine acts by binding to a site located within the NMDA associated ion channel and thus prevents Ca²⁺ flux.

Bosutinib is an orally active Src/Abl tyrosine kinase inhibitor with IC₅₀ of 1.2 nM and 1 nM, respectively.

Cynaroside (Luteolin 7-glucoside) is a flavonoid compound that exhibits anti-oxidative capabilities. Cynaroside is also a potent influenza RNA-dependent RNA polymerase inhibitor with an IC₅₀ of 32 nM. Cynaroside also is a promising inhibitor for H₂O₂-induced apoptosis, has cytoprotection against oxidative stress-induced cardiovascular diseases. Cynaroside also has antibacterial, antifungal and anticancer activities, antioxidant and anti-inflammatory activities.

SP600125 is an orally active, reversible, and ATP-competitive JNK inhibitor with IC₅₀s of 40, 40 and 90 nM for JNK1, JNK2 and JNK3, respectively. SP600125 is a potent ferroptosis inhibitor. SP600125 induces the transformation of bladder cancer cells from autophagy to apoptosis.

Elesclomol (STA-4783) is a potent copper ionophore and promotes copper-dependent cell death (cuproptosis). Elesclomol specifically binds ferredoxin 1 (FDX1) α2/α3 helices and β5 strand. Elesclomol inhibits FDX1-mediated Fe-S cluster biosynthesis. Elesclomol is an oxidative stress inducer that induces cancer cell apoptosis. Elesclomol is a reactive oxygen species (ROS) inducer. Elesclomol can be used for Menkes and associated disorders of hereditary copper deficiency research.

Nocodazole (Oncodazole) is a rapidly-reversible inhibitor of microtubule. Nocodazole binds to β-tubulin and disrupts microtubule assembly/disassembly dynamics, which prevents mitosis and induces apoptosis in tumor cells. Nocodazole inhibits Bcr-Abl.

MPTP hydrochloride is a brain penetrant dopaminergic neurotoxin. MPTP hydrochloride can be used to induce Parkinson’s Disease model. MPTP hydrochloride, a precusor of MPP⁺, induces apoptosis. MPTP hydrochloride has been verified by MCE with professional biological experiments.

Oxidopamine (6-OHDA) hydrobromide is an antagonist of the neurotransmitter dopamine. Oxidopamine hydrobromide is a widely used neurotoxin and selectively destroys dopaminergic neurons. Oxidopamine hydrobromide promotes COX-2 activation, leading to PGE₂ synthesis and pro-inflammatory cytokine IL-1β secretion. Oxidopamine hydrobromide can be used for the research of Parkinson’s disease (PD), attention-deficit hyperactivity disorder (ADHD), and Lesch-Nyhan syndrome.

MPP+ iodide, a toxic metabolite of the neurotoxin MPTP, causes symptom of Parkinson's disease in animal models by selectively destroying dopaminergic neurons in substantia nigra. MPP+ iodide is taken up by the dopamine transporter into dopaminergic neurons where it exerts its neurotoxic action on mitochondria by affecting complex I of the respiratory chain. MPP+ iodide is also a high affinity substrate for the serotonin transporter (SERT).

Imatinib (STI571) is an orally bioavailable tyrosine kinases inhibitor that selectively inhibits BCR/ABL, v-Abl, PDGFR and c-kit kinase activity. Imatinib (STI571) works by binding close to the ATP binding site, locking it in a closed or self-inhibited conformation, therefore inhibiting the enzyme activity of the protein semicompetitively. Imatinib also is an inhibitor of SARS-CoV and MERS-CoV.

UK-5099 (PF-1005023) is a potent inhibitor of the mitochondrial pyruvate carrier (MPC). UK-5099 (PF-1005023) inhibits pyruvate-dependent O₂ consumption with an IC₅₀ of 50 nM.

Metformin (1,1-Dimethylbiguanide) hydrochloride inhibits the mitochondrial respiratory chain in the liver, leading to AMPK activation and enhancing insulin sensitivity, and can be used in the study of type 2 diabetes. Metformin hydrochloride exerts central glucose-lowering effects by inhibiting Ras-related protein 1 (Rap1) in SF1 hypothalamic neurons. Metformin hydrochloride also inhibits liver oxidative stress, nitrosative stress, inflammation, and apoptosis caused by liver ischemia/reperfusion injury. In addition, Metformin hydrochloride regulates the expression of autophagy-related proteins by activating AMPK and inhibiting the mTOR signaling pathway, thereby inducing tumor cell autophagy and inhibiting the growth of renal cell carcinoma in vitro and in vivo.

Necrosulfonamide is a MLKL and Gasdermin D (GSDMD) inhibitor, capable of separately inhibiting necroptosis and pyroptosis of cells. Necrosulfonamide does not affect the activation of upstream signals, but specifically inhibits the downstream executor oligomerization step. Necrosulfonamide reduces the expression of the key kinases NLRP3 and caspase-1 involved in necroptosis and pyroptosis, activate the Nrf2 pathway and the downstream antioxidant enzymes, and also downregulates a variety of inflammatory factors. Necrosulfonamide plays significant roles in various diseases such as neurodegenerative diseases (such as Parkinson’s disease), tissue damage and ischemia-reperfusion injury, inflammatory bowel disease, osteoarthritis and fracture repair, and hair loss by regulating two important programmed necrosis pathways.

D-AP5 (D-APV) is a selective and competitive NMDA receptor antagonist with a K_d of 1.4 μM. D-AP5 (D-APV) inhibits the glutamate binding site of NMDA receptors.

Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used clinically to treat type 2 diabetes mellitus.
