Description
Bisacodyl is a synthetic compound that belongs to the class of stimulant laxatives. It is a crystalline solid with the chemical formula C22H19NO4 and is known for its effectiveness in treating constipation. Bisacodyl works by stimulating the intestines, increasing the secretion of fluids, and accelerating bowel movements.
Uses
Used in Pharmaceutical Industry:
Bisacodyl is used as a cathartic for the relief of constipation. It is typically prescribed to patients who experience difficulty in bowel movements or have infrequent bowel movements. Bisacodyl acts as a stimulant laxative, increasing the motility of the intestines and promoting the passage of stool.
Used in Medical Research:
Bisacodyl is used in the inhibition of (Na+K)ATPase, the increase of mucosal PGE2, and the activation of adenyl cyclase in rat intestine studies. These studies help researchers understand the mechanisms of action of Bisacodyl and its potential applications in various gastrointestinal disorders.
Brand Names and Forms:
Bisacodyl is available under various brand names and forms, including Correctol (Schering-Plough HealthCare), Dulcolax (Boehringer Ingelheim), Evac-Q-Tabs (Savage), Feen-a-Mint Tablets (Schering-Plough HealthCare), Modane (Savage), SK-Bisacodyl (SmithKline Beecham), and Theralax (SmithKline Beecham). These products come in the form of tablets and caplets, making it convenient for patients to take the medication as prescribed by their healthcare provider.

Manufacturing Process
Preparation of (4,4'-Dihydroxy-Diphenyl)-(Pyridyl-2)-Methane
70.0 grams of α-pyridine aldehyde are fed portionwise with stirring and
cooling to a mixture of 200 grams of phenol and 100 cc of concentrated
sulfuric acid. The reaction mixture is allowed to stand for a while with
repeated stirring, whereby it becomes syrupy, neutralized with sodium
carbonate, dissolved in methanol and filtered. The filtrate is introduced into a
large quantity of water and the resulting precipitate is recrystallized from a
methanol/water mixture. Colorless crystals are obtained of MP 254°C. When
using zinc chloride or tin tetrachloride and warming to a temperature of about
50°C, a corresponding result is obtained.
Preparation of Bisacodyl: 5 grams of (4,4'-dihydroxy-diphenyl)-(pyridyl-2)-
methane are heated with 5 grams of anhydrous sodium acetate and 20 cc of
acetic anhydride for three hours over a boiling water bath. The cooled reaction
mixture is poured into water, whereby after a while a colorless substance
precipitates, which is filtered off with suction, washed with water and
recrystallized from aqueous ethanol. Colorless bright crystals, MP 138°C are
obtained.
Clinical Use
Laxative
Veterinary Drugs and Treatments
Bisacodyl oral and rectal products are used as stimulant cathartics
in dogs and cats.
Drug interactions
Potentially hazardous interactions with other drugs
None known
Metabolism
Bisacodyl is rapidly hydrolysed to the active principle
bis-(p-hydroxyphenyl)-pyridyl-2-methane (BHPM),
mainly by esterases of the enteric mucosa. After oral
and rectal administration, only small amounts of the
drug are absorbed and are almost completely conjugated
in the intestinal wall and the liver to form the inactive
BHPM glucuronide. Following the administration of
bisacodyl coated tablets, an average of 51.8% of the
dose was recovered in the faeces as free BHPM and an
average of 10.5% of the dose was recovered in the urine
as BHPM glucuronide. Following the administration as a
suppository, an average of 3.1% of the dose was recoveredas BHPM glucuronide in the urine. Stool contained
large amounts of BHPM (90% of the total excretion) in
addition to small amounts of unchanged bisacodyl
Check Digit Verification of cas no
The CAS Registry Mumber 603-50-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 603-50:
(5*6)+(4*0)+(3*3)+(2*5)+(1*0)=49
49 % 10 = 9
So 603-50-9 is a valid CAS Registry Number.

Light-induced metal-free transformations of unactivated pyridotriazoles
Zhang, Ziyan,Yadagiri, Dongari,Gevorgyan, Vladimir
, p. 8399 - 8404 (2019/09/30)
A highly efficient and practical method for incorporation of the arylmethylpyridyl moiety into diverse molecules has been developed. This method features the transition metal-free light-induced room temperature transformation of pyridotriazoles into pyridyl carbenes, which are capable of smooth arylation, X-H insertion, and cyclopropanation reactions. The synthetic usefulness of the developed method was illustrated in a facile synthesis of biologically active molecules.
Synthesis of triphenylmethane derivative: Bisacodyl
Mereyala, Hari Babu,Sambaru, Kalyani
, p. 615 - 617 (2007/10/03)
A new method for the synthesis of bisacodyl 1 is described. The key step involves migration of 2-pyridacyl group of phenyl pyridine-2-carboxylate 4 in AlCl3 at 160 °C to yield the intermediate 4-hydroxyphenyl (2-pyridyl) ketone 5a. The reaction of 5a with phenol using H3PO 4 gives 1. This method has advantage over the existing literature methods because easily available pyridine-2-carboxylic acid is used as a starting material instead of the less stable pyridine-2-carboxaldehyde.
