AZD7687 is a novel, potent, selective, reversible and pyrazinecarboxamide-based inhibitor of diacylglycerol acyltransferase 1 (DGAT1) with an IC50 value of 80 nM for hDGAT1. AZD7687 attenuates postprandial triacylglyceride excursion. AZD7687 markedly reduced postprandial TAG excursion with a steep concentration-effect relationship. Incremental TAG AUC (area under the serum concentration vs. time curve) following SMM 60% was decreased >75% from baseline at doses ≥5 mg (p < 0.0001 vs. placebo). Serum levels of diacylglycerol, specifically measured with mass spectrometry, did not increase after AZD7687 administration. Nausea, vomiting and diarrhoea were reported with increasing doses and they limited dose escalation. Lowering of SMM fat content to 45 or 30% in five cohorts gradually reduced the frequency of gastrointestinal symptoms at a given dose of AZD7687.
| ln Vitro |
AZD7687's IC50 was roughly 100 nM, 60 nM, and 80 nM in in vitro recombinant mouse, dog, and human DGAT1 enzyme tests, respectively. Compound 30, AZD7687, exhibited activity against muscarinic M2 receptor (IC50 = 80.5 μM), fatty acid amide hydrolase (IC50 = 3.7 μM), acyl-CoA:cholesterol acetyltransferase (79% at 10 μM), and diphosphate inhibition of esterase PDE10A1 (IC50 = 5.5 μM). There has been no evidence of any activity against human DGAT2 [1][2].

| ln Vivo |
The identical skin phenotype, including baldness and atrophy of the sebaceous glands, as observed in the skin of DGAT1-/- mice is produced when DGAT1 is long-term pharmacologically inhibited in mice treated with AZD7687. The effects of AZD7687 on the skin can be reversed and are depending on time and dose [3].

| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (6.80 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with heating and sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.80 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
