Derazantinib (ARQ-087) (ARQ-087) is an ATP competitive tyrosine kinase inhibitor. It exhibits potent activity against FGFR1 FGFR2 FGFR3 chondrocytes (IC50s: 4.5 nM 1.8 nM 4.5 nM).

Amygdalin (Laetrile) has antifibrotic, antitumor, anti-inflammatory and analgesic effects, amygdalin joint HSYA could inhibit the degeneration of the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and better than the single use of Amygdalin or HSYA. Amygdalin induces apoptotic cell death in human DU145 and LNCaP prostate cancer cells by caspase-3 activation through down-regulation of Bcl-2 and up-regulation of Bax.

BNTA is a potent extracellular matrix (ECM) modulator. In a rat model of arthritis, BNTA modulates arthritis by promoting the synthesis of cartilage structural molecules on chondrocytes through the induction of superoxide dismutase 3 (SOD3) and regulating chondrogenesis through superoxide anion elimination.

1. Monotropein (Monotropeine) has antinociceptive action. 2. Monotropein has anti-apoptosis and anti-catabolic activity in chondrocytes. 3. Monotropein has anti-inflammatory action by inhibition of the expressions of inflammatory mediators via NF-κB inactivation, and support its possible therapeutic role in colitis. 4. Monotrope ininhibit the expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) mRNA in LPS-induced RAW 264.7 macrophages.

Indirubin-3′-oxime is an effective inhibitor of cyclin-dependent protein kinases, and may play an obligate role in neuronal apoptosis in Alzheimer's disease.

RAD16-I hydrochloride is a self-assembling peptide with nanofibrous morphology that provides an optimal microenvironment for the proliferation and differentiation of human mesenchymal stem cells (hMSC) into chondrocytes. This peptide, known as RAD16-I, has been extensively studied and serves as a model to assess the amyloid-like staining properties of self-assembling peptide nanofibers (SAPNFs).

AB05831, also known as 2-Acetamido-1,2-dideoxynojirimycin, is a highly potent and specific inhibitor of beta-hexosaminidase. N-Acetyl-3-hexosaminidase (HEX) is a member of lysosomal hydrolases, which catalyzes hydrolysis of terminal, non-reducing N-acetyl-|3-D-glucosamine (GlcNAc) andN-acetyl-(3-D-galactosamine (GalNAc) residues in glycoproteins, gan-gliosides, and glycosaminoglycans (GAGs). HEX, released by chondrocytes into the extracellular compartment, promotes cartilage matrix degradation. Osteoarthritis patients have increased HEX activity in synovial fluid.

Tricetin is a flavonoid isolated from pomegranate.Tricetin is a potent competitive inhibitor of Keap1-Nrf2 protein-protein interaction (PPI) and protects Parkinson's disease patients from 6-OHDA-induced neurotoxicity by activating the Nrf2/HO-1 signaling pathway and blocking mitochondria-dependent apoptotic pathways.Tricetin Inhibits migration and expression of the indicator protease progerin-1 (PS-1) in nasopharyngeal carcinoma through the Akt/GSK-1β pathway.Tricetin inhibits endothelial inflammation induced by oxidized LDL mediated by Egr-1, and protects rat chondrocytes from IL-1β-induced inflammation and apoptosis.Tricetin is an inhibitor of endothelial inflammation induced by oxidized LDL mediated by Egr-1 and protects against IL-1β-induced inflammation and apoptosis.

Vosoritide acetate (BMN 111) is an agonist of the natriuretic peptide receptor 2 (NPR2) that promotes bone growth by influencing chondrocyte proliferation and differentiation [1].

Derazantinib Racemate (ARQ-087 Racemate) is the racemate of Derazantinib, an orally bioavailable, ATP-competitive tyrosine kinase inhibitor with potent activity against FGFR1 FGFR2 FGFR3 chondrocytes (IC50s: 4.5 nM 1.8 nM 4.5 nM).

TIP39, a neuropeptide and an agonist for the parathyroid hormone receptor type 2 (PTH2R), effectively increases cAMP levels in COS-7 cells featuring recombinant PTH2R from humans or rats (EC50s = 0.5 and 0.8 nM, respectively), as well as in F-11 cells that naturally express PTH2R (EC50 = 1.15 nM). Furthermore, TIP39 at 1 nM halts the cell cycle at the G0/G1 phase and reduces Sox9 expression, a crucial regulator of cartilage differentiation, in CFK2 rat chondrocytes. Additionally, administering 100 pmol/animal of TIP39 reduces the immobility period in the forced swim test in mice, indicating a potential antidepressant effect.

Kartogenin (KGN) is an activator of the smad4/smad5 pathway, and promotes the selective differentiation of multipotent mesenchymal stem cells into chondrocytes.
