Lobeglitazone sulfate was approved by the Ministry of Food and Drug Safety (Korea) on July 4, 2013. It was developed and marketed as Duvie® by Chong Kun Dang Corporation.
Lobeglitazone is an agonist for both PPARα and PPARγ, and it works as an insulin sensitizer by binding to the PPAR receptors in fat cells and making the cells more responsive to insulin. It is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes.
Duvie® is available as tablet for oral use, containing 0.5 mg of free Lobeglitazone. The recommended dose is 0.5 mg once daily.
Lobeglitazone which was reported in our previous works belongs to the class of potent PPARα/γ dual agonists (PPARα EC50: 0.02 μM, PPARγ EC50: 0.018 μM, rosiglitazone; PPARα EC50: >10 μM, PPARγ EC50: 0.02 μM, pioglitazone PPARα EC50: >10 μM, PPARγ EC50: 0.30 μM). Lobeglitazone has excellent pharmacokinetic properties and was shown to have more efficacious in vivo effects in KKAy mice than rosiglitazone and pioglitazone.17 Due to its outstanding pharmacokinetic profile, lobeglitazone was chosen as a promising antidiabetes drug candidate.
Lobeglitazone is used to assist regulation of blood glucose level of diabetes mellitus type 2 patients. It can be used alone or in combination with metformin.

Process Development and Scale-Up of PPAR α/γ Dual Agonist Lobeglitazone Sulfate (CKD-501)
A scaleable synthetic route to the potent PPARα/γ dual agonistic agent, lobeglitazone (1), used for the treatment of type-2 diabetes was developed. The synthetic pathway comprises an effective five-step synthesis. This process involves a consecutive synthesis of the intermediate, pyrimidinyl aminoalcohol (6), from the commercially available 4,6-dichloropyrimidine (3) without the isolation of pyrimidinyl phenoxy ether (4). Significant improvements were also made in the regioselective 1,4-reduction of the intermediate, benzylidene-2,4-thiazolidinedione (10), using Hantzsch dihydropyridine ester (HEH) with silica gel as an acid catalyst. The sulfate salt form of lobeglitazone was selected as a candidate compound for further preclinical and clinical study. More than 2 kg of lobeglitazone sulfate (CKD-501, 2) was prepared in 98.5% purity after the GMP batch. Overall yield of 2 was improved to 52% from 17% of the original medicinal chemistry route.

Lobeglitazone sulfate (Duvie) Lobeglitazone sulfate, an oral peroxisome proliferator-activated receptor (PPARa/c) dual agonist with IC50 = 20 and 18 nM respectively, was developed by Chong Kun Dang Pharmaceutical in Korea for the treatment of diabetes.135 This drug is differentiated from two other PPAR agonists available—pioglitazone and rosiglitazone —which lack PPARa activity.135 The most likely processscale preparation of lobeglitazone sulfate follows the route described in a process communication from Chong Kun Dang Pharmaceutical.136
Commercially available 4,6-dichloropyrimidine (152) was treated with a stoichiometric equivalent of p-methoxyphenol (153) in the presence of KF in warm DMF (Scheme 24). Upon completion of this reaction, 2-methylaminoethanol was added to the mixture to provide pyrimidine 154 in high yield.137
Next, alcohol 154 underwent a substitution reaction with p-fluorobenzaldehyde (155) under basic conditions to provide alkoxy benzaldehyde 156 which was converted to the benzylidene thiazolidindione 158 upon subjection to Knoevenagel conditions with 2,4-thiazolidinedione (157) in 90% yield.
Finally, reduction of olefin 158 was facilitated by treatment with the Hantzsch ester (159) in the presence of silica gel followed by treatment with methanolic sulfuric acid (96%) at low temperature to ultimately furnish lobeglitazone sulfate in 90% yield.
