3485-62-9 Usage
Description
Clidinium is a gastrointestinal muscarinic receptor antagonist (Ki = 3 nM against [3H]quinuclidinyl benzilate binding in rat colonic enterocytes). Administration of clidinium, at a dose of 1 mg/kg, slows intestinal transit and induces constipation in mice. This clidinium-induced constipation induces serum hyperammonemia and decreases clonic, myoclonic, and tonic seizure thresholds in a murine pentylenetetrazole-induced epilepsy model.

Definition
ChEBI: The bromide salt of clinidium. It is used for the symptomatic treatment of peptic ulcer disease and also to help relieve abdominal or stomach spasms or cramps due to colicky abdominal pain, diverticulitis, and irritable bowel syndrome.
Manufacturing Process
5.12 g of 1-azabicyclo[2.2.2]-3-octanol were refluxed with a suspension of
0.92 g of finely divided sodium in 50 cc of toluene, until most of the sodium
had reacted (about 4 hours). The thus obtained suspension of the white
amorphous alcoholate was cooled with ice, and reacted with 10.16 g of
diphenylchloroacetyl chloride, which was added in form of a solution in
approximately 40 cc of toluene. The mixture was stirred for 1 hour at room
temperature. Small amounts of unreacted sodium were destroyed with
isopropanol, and 120 cc of 1 N hydrochloric acid were then added, The
mixture was refluxed for 1/2 hour, in order to convert the first formed
product, diphenylchloroacetic acid ester of 1-azabicyclo[2.2.2]-3-octanol, into
the corresponding benzilic acid ester.
The toluene phase was separated and discarded. The aqueous phase, together
with a precipitated water- and toluene-insoluble oil, was made alkaline and
extracted repeatedly with chloroform. The chloroform solution was
concentrated in vacuo. The residue was recrystallized from a mixture of
acetone and ether (alternatively, from chloroform and ether), and formed
needles melting at 164° to 165°C. It was identified as 3-benziloyloxy-1-
azabicyclo[2.2.2]octane.
3-Benziloyloxy-1-azabicyclo[2.2.2]octane methobromide was prepared by
adding 20 cc of a 30% solution of methyl bromide in ether to a solution of 2.5
g of 3-benziloyloxy-1-azabicyclo[2.2.2]octane in 20 cc of chloroform. After
standing for 3 hours at room temperature and 15 hours at +5°C, a crystalline
precipitate had formed. This was filtered off and recrystallized from a mixture
of methanol, acetone, and ether; prisms melting at 240° to 241°C.
Brand name
Quarzan (Roche).
Therapeutic Function
Anticholinergic, Antiulcer
General Description
Clidinium bromide, 3-hydroxy-1-methylquinuclidinium bromide benzilate (Quarzan),is a white or nearly white, almost odorless, crystalline powderthat is optically inactive. It is soluble in water and alcohol butonly very slightly soluble in ether and benzene.
Clinical Use
This anticholinergic agent is marketed alone and in combinationwith the minor tranquilizer chlordiazepoxide (Librium)in a product known as Librax. The rationale of the combinationfor the treatment of GI complaints is the use of an anxiety-reducing agent together with an anticholinergic agent,based on the recognized contribution of anxiety to the developmentof the diseased condition. It is suggested for pepticulcer, hyperchlorhydria, ulcerative or spastic colon, anxietystates with GI manifestations, nervous stomach, irritable orspastic colon, and others. Clidinium bromide is contraindicatedin glaucoma and other conditions that may be aggravatedby the parasympatholytic action, such as prostatic hypertrophyin elderly men, which could lead to urinary retention.
Check Digit Verification of cas no
The CAS Registry Mumber 3485-62-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,8 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3485-62:
(6*3)+(5*4)+(4*8)+(3*5)+(2*6)+(1*2)=99
99 % 10 = 9
So 3485-62-9 is a valid CAS Registry Number.
