Description
Carbidopa, also known as (S)-3-(3,4-dihydroxyphenyl)-2-hydrazinyl-2-methylpropanoic acid, is a white crystalline powder that is slightly soluble in water with a pKa of 7.8. It is a peripheral decarboxylase inhibitor and a selective aryl hydrocarbon receptor (AhR) modulator. Carbidopa is metabolized into two main metabolites, which are primarily eliminated in the urine, either unchanged or as glucuronide conjugates. It is used in the management of Parkinson's disease and has no antiparkinson activity by itself but helps reduce the peripheral adverse effects of levodopa. Carbidopa is a member of hydrazines, a hydrate, a monocarboxylic acid, and a member of catechols.
Uses
Used in Parkinson's Disease Research:
Carbidopa is used as a dopa decarboxylase inhibitor for the research of Parkinson's disease. It prevents the conversion of levodopa to dopamine, thus reducing the peripheral adverse effects of levodopa and enhancing its effectiveness in treating Parkinson's disease.
Used in Pancreatic Cancer Research:
Carbidopa is used as an inhibitor of pancreatic cancer cell and tumor growth, providing a potential therapeutic approach for pancreatic cancer treatment.
Used as a Pharmaceutical Reference Standard:
Carbidopa may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by chromatography techniques, ensuring the quality and consistency of the drug in various applications.
Used in Drug Formulations:
Carbidopa is combined with levodopa for the treatment of Parkinson's disease and Parkinson's syndrome, providing a more effective and safer treatment option by reducing the peripheral conversion of levodopa to dopamine and minimizing side effects.
Check Digit Verification of cas no
The CAS Registry Mumber 38821-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,8,2 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 38821-49:
(7*3)+(6*8)+(5*8)+(4*2)+(3*1)+(2*4)+(1*9)=137
137 % 10 = 7
So 38821-49-7 is a valid CAS Registry Number.
