Abstract

Canagliflozin(Invokana) is an oral diabetes medicine that helps control blood sugar levels. It works by helping the kidneys get rid of glucose from your bloodstream. Invokana is used together with diet and exercise to treat type 2 diabetes. To mention the advantage, this drug helps patients to reduce blood sugars without increasing the likelihood of gaining weight as long as a healthy, balanced diet is followed and regular exercise taken.

Oral diabetes drugs

Canagliflozin is an Inhibitor drug for SGLT2. It can lower blood glucose levels by expelling the glucose from the body through the kidneys after its decomposition. In addition, Canagliflozin has a broad prospect due to its significant antiobesity effects and few hypoglycemic events. According to the results of 2 phase III clinical trials on June 9th, 2012, Canagliflozin, which is an Experimental type 2 diabetes drug of JNJ is better than Januvia of Merck or an older drug called glimepiride. Meanwhile, Canagliflozin has a more significant antiobesity effect. Compared with glimepiride, it causes less hypoglycemic events. On January 11th, 2013, Janssen Pharmaceutical of JNJ announced that its diabetes drug canagliflozin (trade name INVOKANA?)was recommended and approved by the committee of experts of FDA by the vote of 10 to 5 to treat adult patients with type 2 diabetes. On march 29th, 2013, canagliflozin (trade name INVOKANA, Janssen Pharmaceutical China of JNJ)was approved by the US Food and Drug Administration (FDA) to control blood glucose of adult patients with type 2 diabetes. On December 25th, 2013, Janssen Pharmaceutical of JNJ announced that new diabetes drug INVOKANA(canagliflozin)was approved by European Commission(EC)to treat adult patients with type 2 diabetes and improve glucose control. In September, 2014, Canagliflozin Won the positive Suggestions for recommend approval of Committee for Medicinal Products for Human Use (CHMP) of? European Medicines Agency (EMA). In addition, Canagliflozin has been approved by FDA in March this year, and approved by Australia rencently. Canagliflozin is a once daily oral diabetes drug, which works by inhibiting sodium glucose co-transporter 2 (SGLT2)as a new drug. It can lower blood glucose levels by interdicting the blood glucose reabsorption of the kidneys and increasing the excretion of blood glucose in urine. Compared with non-diabetic population, the kidneys of adult patients with type 2 diabetes absorb a large number of glucose into the blood stream, which will push up the blood glucose levels. Canagliflozin is one of the most promising drug candidates of JNJ. The department of Janssen Pharmaceutical of JNJ has the rights to sell this drug in North America, South America, Europe, Middle East, Africa, Australia, New Zealand and some Asian countries.

Clinical study

Canagliflozin is the first FDA approved inhibitor for SGLT2 and used to treat adult patients with type 2 diabetes. As a kind of glucose transporter, SGLT has two subtypes of SGLT1and SGLT2, which are distributed in the intestinal mucosa and renal tubular respectively, and able to transport glucose into the blood. Canagliflozin can inhibit SLCT2 and, interdict the reabsorption of glucose in Renal tubular and increase the excretion of blood glucose in urine. Thus, the blood glucose levels can be lowered. Glucose was passed into the urine through the kidneys, accompanied by renal impairment, symptomatic hypotension, fungal infections and other side effects. 9 clinical trials involving 10285 patients have demonstrated the safety and efficacy of Invokana, either used alone or in combination with other hypoglycemic agents. In a double-blind controlled trial for 26 weeks, 584 adult patients with type 2 diabetes were divided into three groups, namely 100mg Canagliflozin group, 300mg Canagliflozin group and placebo group. Compared with placebo group, the HbA1c of the 100mg Canagliflozin group and 300mg Canagliflozin group was lowed extra 0.91% and 1.16% respectively.

How it works

Invokana is in a class of drugs called sodium-glucose transport protein 2 (or SGLT2) inhibitors, which drugs work by increasing the amount of glucose that gets passed out in the urine. When blood passes through the kidneys, the kidneys filter glucose out of the blood and the SGLT proteins then help reabsorb glucose back into the blood. SGLT2 proteins are responsible for 90% of the glucose that is reabsorbed, so by blocking the action these proteins, less glucose is reabsorbed and so more glucose is excreted via the urine.

Invokana tables

Invokana is supplied as film-coated tablets for oral administration, containing 102 and 306 mg of canagliflozin in each tablet strength, corresponding to 100 mg and 300 mg of canagliflozin (anhydrous), respectively. Inactive ingredients of the core tablet are croscarmellose sodium, hydroxypropyl cellulose, lactose anhydrous, magnesium stearate, and microcrystalline cellulose. The magnesium stearate is vegetable-sourced. The tablets are finished with a commercially available film-coating consisting of the following excipients: polyvinyl alcohol (partially hydrolyzed), titanium dioxide, macrogol/PEG, talc, and iron oxide yellow, E172 (100 mg tablet only).

Taboo

You should not use Invokana if you have severe kidney disease (or if you are on dialysis). Invokana is not for treating type 1 diabetes.

Description

In March 2013, the US FDA approved canagliflozin (JNJ-28431754; TA-7284) for the treatment of type 2 diabetes in adults. Canagliflozin is the first US-approved sodium-glucose co-transporter (SGLT) inhibitor for the treatment of type 2 diabetes. Inhibition of renal SGLT suppresses glucose reabsorption, which permits glucose excretion into urine and reduction of hyperglycemia. Canagliflozin was discovered through structural modifications of phlorizin, a known inhibitor of renal glucose reabsorption. Early modifications of OH groups on the glucose moiety were insufficient to adequately impair hydrolysis by intestinal β-glucosidase. Introduction of the C-glucoside moiety, as in the clinical candidate dapagliflozin, afforded sufficient resistance to hydrolysis. Finally, incorporation of the thiophene moiety in canagliflozin provided improved potency for hSGLT2 (exclusive to kidney), IC50=2.2 nM, while offering significant selectivity over hSGLT1 (in kidney and heart), IC50=910 nM. Hyperglycemic, high-fat (HF) diet fedmice (KKstrain) that received a single 3 mg/kg oral dose of canagliflozin had a 48% reduction in blood glucose levels after 6 h versus vehicle-treatedmice. Noteworthy in themultistep synthesis of canagliflozin is the stereoselective formation of the β-C-glucoside which is accomplished by coupling of the aryllithiumaglycone with 2,3,4,6-tetra-O-trimethylsilyl-β-Dgluconolactone followed by desilylation and stereoselective reduction with triethylsilane and boron trifluoride etherate.

Stereoselective Preparation of C-Aryl Glycosides via Visible-Light-Induced Nickel-Catalyzed Reductive Cross-Coupling of Glycosyl Chlorides and Aryl Bromides

Mou, Ze-Dong,Wang, Jia-Xi,Zhang, Xia,Niu, Dawen

supporting information, p. 3025 - 3029 (2021/05/27)

A nickel-catalyzed cross-coupling reaction of glycosyl chlorides with aryl bromides has been developed. The reaction proceeds smoothly under visible-light irradiation and features the use of bench-stable glycosyl chlorides, allowing the highly stereoselective synthesis of C-aryl glycosides. (Figure presented.).

METHOD FOR PRODUCING C-ARYL GLYCOSIDE DERIVATIVE

Paragraph 0091-0097, (2021/06/25)

PROBLEM TO BE SOLVED: To provide a method that can produce a C-aryl glycoside derivative stably and inexpensively. SOLUTION: A method for producing a C-aryl glycoside derivative includes the step of mixing, for example, in an organic solvent, the following benzyl-protected C-aryl glycoside derivative (IaA), at least one silyl compound selected from trimethylsilyl chloride and trimethylsilyl bromide, and an alkali metal iodide, thereby producing the following C-aryl glycoside derivative (IIaA).

Syntheses of SGLT2 inhibitors by Ni- And Pd-catalyzed fukuyama coupling reactions

Kato, Daiki,Mashima, Kazushi,Nagae, Haruki,Seki, Masahiko,Talode, Jalindar,Tsurugi, Hayato

, p. 12382 - 12392 (2020/11/09)

Nickel- and palladium-catalyzed Fukuyama coupling reactions of a D-gluconolactone-derived thioester with arylzinc reagents at ambient temperature provided the corresponding multifunctional aryl ketones in high yield. Ligand screening for the nickel-catalyzed Fukuyama coupling reactions indicated that 1,2- bis(dicyclohexylphosphino)ethane (dCype) served as a superior supporting ligand to improve the product yield. In addition, Pd/C was a practical alternative that enabled ligand-free Fukuyama coupling reactions and was efficiently applied to the key C-C bond-forming step to prepare canagliflozin and dapagliflozin, which are diabetic SGLT2 inhibitors of current interest.
