Levodopa CAS#59-92-7
Levodopa, also known as L-DOPA or 3,4-dihydroxy-L-phenylalanine, is a naturally occurring amino acid and a critical precursor in the biosynthesis of the neurotransmitters dopamine, norepinephrine, and epinephrine. With the molecular formula C9H11NO4, levodopa is a large, neutral amino acid that plays a significant role in the treatment of Parkinson’s disease due to its ability to cross the blood-brain barrier and be converted into dopamine.
Chemically, levodopa is synthesized from the precursor amino acid tyrosine through the action of the enzyme tyrosine hydroxylase. As a medication, levodopa is often formulated with a peripheral DOPA decarboxylase inhibitor to reduce its conversion to dopamine outside the brain, thereby increasing its effectiveness and reducing side effects.
Levodopa is characterized by its effectiveness in alleviating the motor symptoms of Parkinson’s disease, such as tremors, rigidity, and bradykinesia. It is typically administered orally and absorbed from the gastrointestinal tract, where it is then transported to the brain.
In summary, levodopa is a vital pharmaceutical compound used in neurology for its role in treating Parkinson’s disease by replenishing the brain’s dopamine levels. Its targeted delivery and conversion to dopamine make it an essential treatment option for managing the motor symptoms associated with this condition.

Urapidil is a sympathetic antihypertensive drug. It acts as ?? 1 ?C adrenoceptor antagonists and 5-HT 1A receptor agonists act. Although the initial report showed that urapidil was also a ?? 2 ?C adrenoceptor agonist, which was not confirmed in later studies, proved that it had no agonist effect in the saphenous vein of dogs and ileum of guinea pigs. With others ?? Unlike 1-adrenoceptor villains, urapidil does not cause response tachycardia, which may be connected to its weak ?? 1-adrenoceptor antagonist activity and its impact on heart vagal drive. Urapidil has actually not been approved by the US Food and drug administration, yet it is offered in Europe.
