Nimazone is an anti-inflammatory drug.

APREMILAST, (±)- is a mixture of isomers, one of them is therapeutic active S form (apremilast), an inhibitor of phosphodiesterase 4. This active form is sold under the brand name OTEZLA for the treatment of adult patients with active psoriatic arthritis.

Sulindac sulfide, an active metabolite of the nonsteroidal anti-inflammatory drug (NSAID) sulindac, directly binds to the Ras gene product p21ras in a non-covalent manner. Sulindac sulfide strongly inhibits Ras-induced malignant transformation and Ras/Raf dependent transactivation, due to its action at the most critical site in Ras signaling. Sulindac sulfide was proposed as a lead compound in the search for novel anti-cancer drugs, which directly inhibit Ras-mediated cell proliferation and malignant transformation. Experiments on rodents have revealed that sulindac sulfide effectively inhibited tumor growth in colorectal cancer cell xenografts mice. In addition, was shown, that sulindac sulfide inhibited ABCC1-mediated transport of appropriate endogenous and xenobiotic substrates. The drug was selectivity for ABCC1 as compared with ABCB1 and ABCG2. These properties allow designing novel ABCC1 inhibitors by chemically modifying sulindac sulfide to improve potency and selectivity to inhibit ABCC1-mediated efflux for preventing drug resistance and tumor recurrence or secondary tumor formation following chemotherapy.

Thiosalicylic acid is an analgesic and anti-inflammatory agent. It is used (in form of sodium salt) to relieve symptoms of acute gout, painful musculoskeletal conditions, osteoarthritis and rheumatic fever. The drug exerts its action by inhibiting prostaglandin synthesis. Thiosalicylic acid usage is associated with the risk of contact dermatitis.

Valdecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, is classified as a nonsteroidal anti-inflammatory drug (NSAID). Valdecoxib was manufactured and marketed under the brand name Bextra. Bextra was indicated for relief of the signs and symptoms of osteoarthritis and adult rheumatoid arthritis. For the treatment of primary dysmenorrhea. But in 2005 FDA requested that Pfizer withdraw Bextra from the American market, because the Agency had concluded that the overall risk versus benefit profile of Bextra was unfavorable. That conclusion was based on the potential increased risk for serious cardiovascular (CV) adverse events, an increased risk of serious skin reactions (e.g., toxic epidermal necrolysis, Stevens-Johnson syndrome, erythema multiforme) compared to other NSAIDs, and the fact that Bextra had not been shown to offer any unique advantages over the other available NSAIDs.

Salsalate is a dimer of salicylic acid. Upon administration, it is metabolically hydrolyzed to salicylic acid. Salsalate is is a nonsteroidal anti-inflammatory agent for oral administration for treatment of rheumatoid arthritis, osteoarthritis and related rheumatoid disorders. In addition, salsalate is investigated for treatment of type 2 diabetes.
