Description
S-Amlodipine, also known as Levamlodipine Besylate, is the (S)-enantiomer salt of Amlodipine (A633495). It is a dihydropyridine calcium channel blocker, with its primary activity residing in the (-)-isomer. S-Amlodipine is characterized by its ability to selectively block calcium channels, which leads to a range of therapeutic effects.
Uses
Used in Pharmaceutical Industry:
S-Amlodipine is used as a pharmaceutical agent for the treatment of various cardiovascular conditions. Its primary application is in the management of hypertension, as it helps to relax blood vessel walls and improve blood flow. This, in turn, reduces the force with which the heart pumps blood, leading to a decrease in blood pressure.
Additionally, S-Amlodipine is used to treat stable and vasospastic angina, which are types of chest pain caused by inadequate blood supply to the heart. By dilating the coronary arteries, it increases the blood flow to the heart muscle, thereby alleviating the symptoms of angina.
Furthermore, S-Amlodipine is utilized in the treatment of certain heart rhythm disorders, as it can help to regulate the heart's electrical activity and maintain a normal heart rate.
Used in Research and Development:
In the field of research and development, S-Amlodipine serves as a valuable compound for studying the effects of calcium channel blockers on various physiological processes. Its selective action on calcium channels allows scientists to investigate the role of these channels in different diseases and conditions, potentially leading to the discovery of new therapeutic targets and treatments.
Check Digit Verification of cas no
The CAS Registry Mumber 150566-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,5,6 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 150566-71:
(8*1)+(7*5)+(6*0)+(5*5)+(4*6)+(3*6)+(2*7)+(1*1)=125
125 % 10 = 5
So 150566-71-5 is a valid CAS Registry Number.

A simple three-step pilot-scale preparation of 1, along with the optimization of a resolution process on the racemate amlodipine, is reported.
PROCESS FOR PRODUCING ENANTIOMER OF AMLODIPINE IN HIGH OPTICAL PURITY
-
Page/Page column 18-19, (2010/11/08)
The present invention relates to a process for preparation of optically pure (S)-amlodipine-L-hemitartrate DMF solvate comprising the steps of treating (R,S) amlodipine base with L-tartaric acid in the presence of dimethyl formamide and a co-solvent. The invention also relates to a process for converting (R) or(S)-amlopidine-L-hemitartrate DMF solvate into their besylates without isolating free chiral amlopidine base after solution.
