K-833

K-833 is a GPR119 agonist with EC₅₀ values of 39.8 nM (human), 100nM (mouse), 75.4 nM (rat) and 12.6 nM (dog). K-833 demonstrates a modest increase in GLP-1 secretion and leads to a synergistic increase in GLP-1 levels when combined with AM-5262 (HY-16619) in acute gut peptide secretion assays in mice. K-833 can be used in studies on weight loss.

Biological Activity

Description

In Vitro

K-833 shows modest antagonism of the human M1 receptor (IC₅₀ = 4.5 μM), inhibition of agonist binding to the human nonselective sigma receptors (IC₅₀ = 2.7 μM) and moderate reversible inhibition of the CYP2B6 (IC₅₀ = 8.6 μM)^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .

In Vivo

K-833 (30 mg/kg, i.g., single dose) demonstrates a modest increase in GLP-1 secretion in acute gut peptide secretion assays in mice^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Male 10-12 week old C57BL/6J mice^[1]
Dosage:

30 mg/kg or combined with AM-5262 (HY-16619) (30 mg/kg)
Administration:

i.g. for a single dose
Result:

Led to a modest increase in GLP-1 secretion.
Led to a synergistic increase in GLP-1 levels when combined with AM-5262.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
