Anagliptin (formerly known as SK0403) is a novel, potent, orally bioactive, and extremely selective DPP-4 (dipeptidyl peptidase 4) inhibitor with an IC50 of 3.8 nM. It is less selective against DPP-8/9 (IC50 = 68, 60 nM). In Japan, angliptin received approval in 2012 to treat type 2 diabetes mellitus. In clinical trials, these agents not only improved glycemic control but also improved lipid metabolism. In an animal model with high cholesterol, anagliptin had a lipid-lowering effect. This finding implied that the effect was caused by hepatic lipid synthesis being downregulated. Beyond its effects on glucose reduction, anagliptin may also have positive effects on lipid metabolism.
| Targets |
DPP-4 (IC50 = 3.8 nM); DPP-9 (IC50 = 60 nM); DPP-8 (IC50 = 68 nM)
Anagliptin (SK-0403) (0-100 μM; 24 h) educes the proliferation of smooth muscle cells induced by s-DPP-4[2]. Anagliptin (100 μM; 10 min) lowers TNF-α production in cultured monocytes[2]. Anagliptin (0.001-10 μM; 24 h) significantly reduces the activity of the protein that binds to sterol regulatory elements in HepG2 cells (21% decrease)[3]. |

Anagliptin (SK-0403) (0-100 μM; 24 h) educes the proliferation of smooth muscle cells induced by s-DPP-4[2].
Anagliptin (100 μM; 10 min) lowers TNF-α production in cultured monocytes[2]. Anagliptin (0.001-10 μM; 24 h) significantly reduces the activity of the protein that binds to sterol regulatory elements in HepG2 cells (21% decrease)[3]. n a sterol regulatory element-binding protein (SREBP) transactivation assay using HepG2 cells, Anagliptin at concentrations of 0.001–10 μmol/L significantly suppressed SREBP promoter activity in a concentration-dependent manner, with a maximum suppression of approximately 21% compared to the control. [3] |
| ln Vivo |
Anagliptin (SK-0403) (0.3%; in diet; 16 weeks) in mice lacking apoliporotein E (apoE) decreases atherosclerotic lesions but does not raise circulating EPC counts[2].
Anagliptin (0.3%; in diet; 4 weeks) shows a lipid-lowering effect in a hyperlipidemic mice model[3]. Administration of Anagliptin (0.3% in diet) for 4 weeks to male low-density lipoprotein receptor (LDLR)-deficient mice significantly reduced plasma total cholesterol levels by 14% and triglyceride levels by 27% compared to the control group. [3] High-performance liquid chromatography analysis revealed that Anagliptin treatment significantly decreased plasma very low-density lipoprotein cholesterol (VLDL-C) and low-density lipoprotein cholesterol (LDL-C) levels, while high-density lipoprotein cholesterol (HDL-C) showed a non-significant decreasing trend. [3] In LDLR-deficient mice, Anagliptin treatment (0.3% in diet for 2 weeks) significantly decreased the hepatic mRNA expression level of SREBP-2 by 15% during the night, while SREBP-1c expression was not significantly altered. [3] DNA microarray analysis of liver samples from Anagliptin-treated mice showed significant associations with pathways related to lipid metabolism, including nuclear receptors in lipid metabolism, fatty acid biosynthesis, and statin pathway. [3] Hepatic de novo triglyceride synthesis tended to be reduced in Anagliptin-treated mice, although the rate of triglyceride secretion in vivo was not altered. [3] |
| Cell Assay |
HepG2 cells were seeded in 96-well plates at 1 × 10⁴ cells per well. The next day, cells were co-transfected with a luciferase reporter vector containing a sterol-responsive element (SRE) promoter (SRE-luc) and a control vector for normalization. Transfection was performed using a commercial transfection reagent. [3]
After 24 hours, the medium was replaced with fresh medium containing 5% lipoprotein-deficient serum. Cells were then stimulated with various concentrations of Anagliptin (0.001–10 μmol/L) for 24 hours. [3] Cell lysates were prepared, and luciferase activity was measured using a commercial dual-luciferase assay system according to the manufacturer's instructions. Firefly luciferase activity was normalized to the control luciferase activity. [3] |
| Animal Protocol |
Male apoliporotein E (apoE)-deficient mice[2]
0.3% In diet, 16 weeks Male LDLR-deficient mice at 5 weeks of age were fed a normal chow diet. [3] Starting at 6 weeks of age, mice were administered Anagliptin mixed into their diet at a concentration of 0.3% (w/w) for a period of 4 weeks (for endpoint measurements) or 2 weeks (for night-time sampling). [3] Control mice received the same diet without Anagliptin. [3] Blood samples were collected at the end of the treatment period for analysis of plasma lipids and glucose. For night-time gene expression analysis, samples were collected between 22:00 and 02:00 hours. [3] Under these conditions, the plasma concentration of Anagliptin was approximately 600 ng/mL, resulting in approximately 80% inhibition of plasma DPP-4 activity. [3] |
| ADME/Pharmacokinetics |
In LDLR-deficient mice fed a diet containing 0.3% anagliptin, plasma concentrations reached approximately 600 ng/mL. [3]
This plasma concentration was associated with approximately 80% inhibition of DPP-4 activity. [3] |

| Additional Infomation |
Alogliptin is an amino acid amide.
Alogliptin is being investigated for the treatment of low-density lipoprotein cholesterol, coronary heart disease, diabetes, glycated hemoglobin, and dipeptidyl peptidase-4 inhibitors. Alogliptin is an orally effective, potent, and selective dipeptidyl peptidase-4 (DPP-4) inhibitor with hypoglycemic activity. Compared to vildagliptin, alogliptin has a longer duration of inhibition of DPP-4 activity. Alogliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor used to treat type 2 diabetes. [3] In addition to its hypoglycemic effect, clinical trials and this preclinical study have shown that alogliptin is beneficial for lipid metabolism, reducing plasma total cholesterol, low-density lipoprotein cholesterol, and triglyceride levels. [3] The possible mechanism of its lipid-lowering effect involves the downregulation of expression and activity of hepatic sterol regulatory element-binding protein-2 (SREBP-2), leading to a reduction in hepatic lipid synthesis. [3] This study used low-density lipoprotein receptor (LDLR) deficient mice as a model of hyperlipidemia with normal blood glucose to distinguish between its lipid-lowering and hypoglycemic effects.
