[1] [2] [3] Cohn describes its use to detect the principal components of digitalis (note that they may not be alkaloids). [4] The reaction with this reagent is also known as the Keller–Kiliani reaction, after C. C. Keller and H. Kiliani, who both used it to study digitalis in the late 19th century.
Keller's reagent can refer to two different reagents: Keller's reagent (metallurgy), used to etch aluminum alloys; Keller's reagent (organic), used to detect alkaloids
The Kiliani–Fischer synthesis, named for German chemists Heinrich Kiliani and Emil Fischer, is a method for synthesizing monosaccharides.It proceeds via synthesis and hydrolysis of a cyanohydrin, followed by reduction of the intermediate acid to the aldehyde, thus elongating the carbon chain of an aldose by one carbon atom while preserving stereochemistry on all the previously present chiral ...
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. [1] Their beneficial medical uses include treatments for congestive heart failure and cardiac arrhythmias ; however, their relative toxicity prevents them ...
According to the ACC/AHA guidelines, intravenous digoxin (cardiac glycoside) can be used in atrial fibrillation (Afib) to assist heartbeats. [90] In multicenter randomised controlled trials, intravenous digoxin was shown to be effective in controlling the heart rate compared to a placebo. [91] [92]
The study, which was published in Nature Medicine on January 20, analyzed data from more than 2 million people with diabetes who took GLP-1 receptor agonist medications like Ozempic and Wegovy.
The function of the enzyme is to perform hydrolysis of various glycosides and oligosaccharides. The most significant oligosaccharide β-glucosidase reacts with is cellulose. Cellulose is a polymer composed of β-1,4-linked glucosyl residues. β-glucosidases, cellulases ( endoglucanases ), cellobiosidases (exoglucanases ) are required by a ...
One of the nation's largest real estate brokerages has agreed to pay $70 million as part of a proposed settlement to resolve more than a dozen lawsuits across the country over agent commissions.
