  • Imiloxan hydrochloride

    CAS:

    Imiloxan hydrochloride is a diagnostic agent that is used to diagnose Parkinson's disease and other neurological disorders. Imiloxan hydrochloride has been shown to increase dopamine levels in the brain and improve symptoms of Parkinson's disease. Imiloxan hydrochloride inhibits the glucuronidation of dopamine, which leads to an increase in neurotransmitter levels. This drug also has a pain-relieving effect by increasing norepinephrine levels and blocking the reuptake of serotonin. Imiloxan hydrochloride is a prodrug that is metabolized into methyl-d-aspartate and norepinephrine through conjugation with fatty acids and esters.

  • Cyamemazine sulfoxide

    CAS:

    Cyamemazine sulfoxide is a histamine H1 receptor antagonist. It has been shown to have strong affinity for the serotonin 5-HT2C and dopamine D2 receptors, as well as the atrial 5-HT2A receptors. Cyamemazine sulfoxide has a low oral bioavailability of about 10% and is metabolized in the liver to cyamemazine and its active form, cyamemazine sulfoxide. Cyamemazine sulfoxide binds to serotonin 5-HT2C receptors with a high affinity, which leads to inhibition of serotonin release from nerve endings in the brain. This drug also inhibits dopamine release from nerve endings in the brain and has been shown to have cardiac effects on heart rate and contractility.

  • 9-Epimitomycin B

    CAS:

    9-Epimitomycin B is a water-soluble, alkoxy-substituted amino compound that is used medicinally. It has antibacterial activity and has been shown to be effective against Gram-positive bacteria such as Staphylococcus aureus, Streptococcus pyogenes, and Enterococcus faecalis. 9-Epimitomycin B inhibits the growth of these bacteria by binding to their ribosomes and inhibiting protein synthesis. The carbon atoms in 9-epimitomycin B are linked to an alkoxy group at one end, which causes it to have a higher affinity for bacterial ribosomes than human ribosomes. 9-Epimitomycin B also binds to mitomycin C, which may be responsible for its antimetabolite properties.

  • Pantoprazole sulfone N-oxide

    CAS:

    Pantoprazole sulfone N-oxide is a prodrug that is converted to the active form pantoprazole in the stomach where it inhibits gastric acid secretion. Pantoprazole sulfone N-oxide has been shown to be genotoxic, and can cause polyvinyl chloride to degrade when stored together. Reconstituted solution of this drug should be used within 24 hours after reconstitution, as the chemical stability of this drug decreases rapidly. Validation studies have been conducted on different analytical methods for determining pantoprazole concentrations in reconstituted solutions, and these methods have been harmonized with those published by the United States Pharmacopeia (USP). The pump inhibitor activity of pantoprazole sulfone N-oxide has been demonstrated in dogs, and it is also useful for treating acid reflux disease in humans. Pantoprazole sulfone N-oxide is unstable at high temperatures (>25°C), so should not be refrigerated or
