CAS#: 53716-49-7

Description: Carprofen is a non-steroidal anti-inflammatory drug that veterinarians prescribe as a supportive treatment for various conditions. It provides day-to-day treatment for pain and inflammation from arthritis in geriatric dogs, joint pain, osteoarthritis, hip dysplasia, and other forms of joint deterioration. It is also used to relieve short-term post-operative pain, inflammation, and swelling after spaying, neutering, and other procedures. Carprofen reduces inflammation by inhibition of COX-2 and other sources of inflammatory prostaglandins. This is targeted protection, in that it does not interfere with COX-1 activity.

Product Data:

Biological target: Carprofen is a nonsteroid anti-inflammatory agent, acts as a multi-target FAAH/COX inhibitor, with IC50s of 3.9 μM, 22.3 μM and 78.6 μM for COX-2, COX-1 and FAAH, respectively.
In vitro activity: Cytoprotective effects of NSAIDs were dependent on the extent of SNP-induced apoptosis and were greatest in CCL and CaCL cell cultures with moderate SNP-induced cytotoxic effects. Preincubation with an NSAID improved cell viability by 15% to 45% when CCL and CaCL cells were subsequently incubated with SNP. Carprofen (10 μg/mL) had the greatest cytoprotective effects for CCL and CaCL cells. Incubation with NSAIDs resulted in a nonsignificant decrease in PGE(2) production from SNP-damaged cells. Reference: Am J Vet Res. 2012 Nov;73(11):1752-8.
In vivo activity: Traumatic brain injury (TBI) initiates acute and chronic inflammatory processes involving cyclooxygenase-2 (COX-2), which may have detrimental effects on outcome and especially on brain regeneration. Therefore carprofen, a COX-2 inhibitor, was studied for whether it would improve outcome and increase neurogenesis after TBI. TBI was induced in Sabra mice that were then treated with vehicle or carprofen for 7 days. Functional outcome was evaluated with the Neurological Severity Score (NSS).Cytokine levels were assessed 4 h post-TBI and water content was measured 24 h post TBI. Mice were given BrdU to label newborn cells for 10 days. The animals were killed 90 days post-TBI and the lesion size as well as newborn cell fate were assessed. Carprofen significantly reduced lesion size (p=0.002), decreased water content in the lesioned cortex (p=0.03), reduced the number of microglia in the lesioned cortex (p<0.0001), and lowered the levels of proinflammatory cytokines (IL-1β, p=0.03; IL-6, p=0.02). Carprofen led to significantly larger improvements in functional outcome (p≤0.008) which were durable over 90 days. Carprofen also induced a threefold increase in the proliferation of new cells in the peri-lesion area (p≤0.002), but newborn cells differentiated mainly into glia in both groups. Carprofen is neuroprotective and induces cell proliferation and gliogenesis after TBI. Treatment with carprofen is consistently associated with better functional outcome. Our results imply that anti-inflammatory drugs may represent novel therapeutic options for TBI. Reference: J Neurotrauma. 2012 Jan 20;29(2):375-84.
