| DrugBank Description: | Grapiprant, also known as AT-001 and CJ-023, is a drug from the piprant class. These molecules were derived from acylsulfonamide and are characterized to be a novel series of para-N-acylaminomethylbenzoic acid known to be prostaglandin receptor antagonists. This type of molecules is currently in development for veterinary patients. This class of drugs was defined in 2013 by the World Health Organization. Grapiprant has been approved in March 2016 by the FDA's Center for Veterinary Medicine as a non-cyclooxygenase inhibiting NSAID for veterinary use. |
| CAS Number: | 415903-37-6 |
| Molecular Weight: | 491.61 |
| DrugBank Indication: | The effects of grapiprant have been investigated in the area of analgesia and anti-inflammation due to the effects that have been reported about this molecule. This molecule has been approved and widely accepted to be used in veterinary for pain reduction in arthritis. In humans, it has been researched to be used in the control of pain and inflammation associated with osteoarthritis. The effect of grapiprant can be explained through the function of prostaglandin E2 (PGE2) which is a key mediator of swelling redness and pain which are classic signs of inflammation. The effect of PGE2 results from its action through four receptor EP1, EP2, EP3 and EP4 from which the EP4 is the primary mediator of PGE2-driven inflammation. |
| DrugBank Pharmacology: | Preclinical studies have shown that grapiprant is very effective to reduce acute and chronic pain and inflammation. The effect of grapiprant seems to be dose-dependent and it is comparable to the effect of rofecoxib and piroxicam. The effects of grapiprant have been reported to be effective in the relief from arthritic pain in canine patients. |
| DrugBank MoA: | Grapiprant is an EP4 prostaglandin receptor antagonist and thus the activity of this drug is thought to be completely related to the selective blockade of this receptor. It binds to human and other mammals EP4 prostaglandin receptor with high affinity without interfering with other prostaglandin pathways which are important for a variety of physiological functions. The binding of grapiprant blocks PGE2 binding and hence its biological effect related to the signaling pain and inflammation cascade. Grapiprant has been accepted very greatly in veterinary as its mechanism of action is a targeted approach to pain management by not having any interaction with the production of prostanoids and thus, by not interacting with other prostaglandin receptor pathways. |
