Glutathione Reductase (GR) Inhibitor

Zinc sulphate is an orally active inhibitor of tyrosinase and glutathione reductase. Zinc sulphate enhances the activity of dopachrome tautomerase. Zinc sulphate delays anagen-related eumelanin production, induces hair hypopigmentation in mice, and accelerates wound healing. Zinc sulphate can be used in research related to benign gastric ulcers. Zinc sulphate can be used in research related to rheumatoid arthritis.

Glyoxal (40% w/w in water) is an α-oxoaldehyde that inhibits Aldose Reductase, Glutathione Reductase, and NADPH synthase. Glyoxal (40% w/w in water) exhibits cytotoxicity, triggers oxidative stress, induces ROS accumulation, lipid peroxidation, mitochondrial membrane potential collapse, DNA damage, apoptosis, and massive production of advanced glycation end products (AGEs). Glyoxal (40% w/w in water) depletes glutathione and activates MAPK phosphorylation. It has lower toxicity as a fixative than paraformaldehyde (PFA) and serves as a precursor for the synthesis of oxalates and dietary carcinogens. Glyoxal (40% w/w in water) is suitable for research related to calcium oxalate kidney stones, diabetes, atherosclerosis, cardiovascular diseases, retinopathy, and cataracts.

Copper(I) oxide is a weak inorganic base, oxidative stress inducer and cytotoxic agent. Copper(I) oxide generates ROS by impairing the activities of Catalase (HY-135849) and glutathione reductase. Copper(I) oxide can be used to activate halides for nucleophilic substitution reactions, and is also suitable for decarboxylation and ring condensation reactions.

Dantrolene-¹³C₃ is the ¹³C₃ labeled Dantrolene. Dantrolene (F368), a muscle relaxant, non-competitively inhibits human erythrocyte glutathione reductase. Ki and IC50 values are 111.6 μM and 52.3 μM, respectively. Dantrolene is a ryanodine receptor antagonist and Ca2+ signaling stabilizer. Dantrolene can be used for the research of muscle spasticity, malignant hyperthermia, Huntington's disease and other neuroleptic malignant syndrome.

Cryptopine is a non-narcotic isoquinoline alkaloid. Cryptopine can reduce the activities of glutathione S-transferase (GST) and glutathione reductase (GR), depletes intracellular glutathione levels, stimulates lipid peroxidation, and induces cytotoxicity by disrupting the cellular defense system. Cryptopine binds stably to key targets of liver cancer and also exhibits anthelmintic activity against Dactylogyrus intermedius. Cryptopine can be used in studies related to liver cancer and Dactylogyrus intermedius infection.
