Product Description

Cetilistat (previously known as ATL-962) is a novel inhibitor of pancreatic and gastrointestinal lipases. It has the potential to treat obesity in both diabetic and non-diabetic patients. It is a highly lipophilic benzoxazinone analog with good PK, safety and tolerability profiles in vivo. Cetilistat acts by inhibiting pancreatic lipase which is an enzyme that breaks down triglycerides in the intestine. Triglycerides from the diet can not be hydrolyzed into the absorbable free fatty acids without this lipase enzyme and are excreted undigested.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
Rat pancreatic lipase activity is inhibited by cetilistat, with an IC50 of 54.8 nM. Moreover, cetilistat is 9.2 times more powerful than rat pancreatic lipase at inhibiting human pancreatic lipase activity, with an IC50 of 5.95 nM[1].
ln Vivo
In male SD rats, cetilistat (3, 10, 30, or 100 mg/kg) inhibits pancreatic lipase activity, reducing intestinal fat absorption[1]. By decreasing intestinal fat absorption, cetilistat (4.9, 14.9, or 50.7 mg/kg; mixed into powdered high-fat food; thrice a day; for three weeks) has anti-obesity and antihyperlipidemic effects on DIO F344 rats[1].
Animal Protocol
Animal/Disease Models: Fifty male SD rats (eight weeks of age)[1]
Doses: 3, 10 , 30, or 100 mg/kg
Route of Administration: Orally administered; prepared in 0.5 % methylcellulose (MC) suspension
Experimental Results: Dose-dependently decreased AUC 0-6 h of plasma triglyceride induced by oral loading of Intrafat 20%. The effect was statistically significant at 3 mg/kg, reaching 45% reduction, while an almost 90 % reduction was achieved at 100 mg/kg.

Animal/Disease Models: Male diet-induced obesity (DIO) F344 rats (five weeks of age)[1]
Doses: 4.9 , 14.9, or 50.7 mg/kg
Route of Administration: Administered as food admixture in a high-fat diet; one time/day; for three weeks
Experimental Results: Dramatically and dose-dependently decreased body weight gain compared with control.

Additional Infomation
Cetilistat is a benzoxazine.
Cetilistat is a novel inhibitor of pancreatic lipase being developed by Alizyme for the treatment of obesity and associated co-morbidities, including type 2 diabetes.
Drug Indication
Investigated for use/treatment in obesity.
Mechanism of Action
Cetilistat is a gastrointestinal lipase inhibitor that blocks fat digestion and absorption, leading to reduced energy intake, and thus weight loss. It is distinct from most other anti-obesity agents as it does not act on the brain to reduce appetite, but acts peripherally. The compound remains in the gastrointestinal tract with no significant absorption into the body.

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
