Chondroitin sulfate is a glycosaminoglycan considered as a symptomatic slow-acting drug for osteoarthritis (SYSADOA). The SYSADOA status suggested a pain relief and increased joint mobility after a relative long regular... Chondroitin sulfate is composed of alternating 1,3-N-acetyl-β-d-galactosamine and 1,4-β-d-glucuronic acid units which bear 4-O- and/or 6-O-sulfations at the N-acetylgalactosamine units disposed of in specific patterns.

Chondroitin sulfate functions as a major component of the intricate extracellular matrix. It is proposed that chondroitin sulfate supply can provide new building blocks for the synthesis of new matrix components.
The anti-inflammatory effect of chondroitin sulfate is thought to be caused by the inhibition of the synthesis of inflammatory intermediates such as the inhibition of nitric oxide synthase, COX-2, microsomal prostaglandin synthase 1 and prostaglandin E2. It is reported also an inhibitory activity in the toll-like receptor 4 which will later inhibit inflammatory cytokines, NFkB and MyD88. This activity suggests a modulation of the MAP kinase pathway. On the other hand, some reports have pointed out an induction on the PKC/PI3K/Akt pathway in neuroblastoma.
The anabolic effect of chondroitin sulfate is suggested to be caused by the inhibition of metalloproteinases such as MMP-1, -3 and -13 as well as ADAMTS-4 and -5.
