BAY-1797 is an orally active and selective P2X4 antagonist (IC50: 211 nM against human P2X4) with anti-nociceptive and anti-inflammatory effects. BAY-1797 displays no or very weak activity on the other P2X ion channels.

NS11394 is a effective and subtype-selective GABA(A) receptor-positive modulator; possesses a functional efficacy selectivity profile of α(5) > α(3) > α(2) > α(1) at GABA(A) alpha subunit-containing receptors.

Incomplete Freund's adjuvant (IFA) is an emulsified mineral oil-based immunostimulant that induces Th2 responses and enhances immune reactions, promoting storage effects at vaccination sites.

Complete Freund's adjuvant (CFA) is an emulsified immunostimulant containing mineral oil and heat-killed mycobacteria, capable of inducing Th1 responses and enhancing immune reactions. It is frequently employed in establishing rat models of rheumatoid arthritis and persistent inflammatory pain.

AP-18 is a potent and selective TRPA1 inhibitor. AP-18 inhibits activation of TRPA1 induced by 50 μM Cinnamaldehyde with an IC50 of 3.1 μM and 4.5 μM for human and mouse TRPA1, respectively. AP-18 could reverse complete Freund's adjuvant (CFA)-induced mechanical hyperalgesia in mice. AP-18 could attenuate Yo-Pro uptake induced by 30 μM AITC in a concentration-dependent manner (IC50= 10.3 μM).

Draflazine is an ENT1 inhibitor. It completely reverses the hypersensitivity in the complete Freund's adjuvant (CFA) model of mechanical hyperalgesia. Draflazine also completely reverses the hypersensitivity of the carrageenan inflammation model of therma

A-889425 is a selectively active oral TRPV1 receptor antagonist with IC50 values of 335 nM (rat) and 34 nM (human). This compound effectively penetrates the central nervous system, reducing mechanical allodynia and the response of spinal neurons to mechanical stimuli in rat paws following inflammation induced by Complete Freund's Adjuvant.

BI-113823 is an orally active and selective bradykinin B1 receptor antagonist. It alleviates mechanical hyperalgesia induced by complete Freund's adjuvant in rats. BI-113823 is applicable for research on chronic inflammatory pain.

NHS-activated 2-octynoic acid-BSA is an immunogen utilized to develop a mouse model for primary biliary cholangitis (PBC). When combined with Complete Freund's Adjuvant, it stimulates the immune system to recognize it as a foreign antigen, triggering an immune response against the body's biliary epithelial cells. This results in the production of anti-PDC-E2 antibodies, causing bile duct damage and inflammation. NHS-activated 2-octynoic acid-BSA is promising for primary biliary cholangitis research.

EP4 receptor antagonist 5 is a potent, selective prostaglandin EP4 receptor antagonist that can alleviate inflammation in the Freund's complete adjuvant (CFA) model.

Thioaspirine is a carbonic anhydrase (CA) inhibitor with Ki values of 64.3 μM for hCA II and 10.9 μM for hCA IX. It effectively alleviates inflammatory pain in mice induced by complete Freund's adjuvant (CFA). Thioaspirine is applicable for research on inflammatory pain.

Nav1.7-IN-20 (Compound 3AG) is an orally active inhibitor of the Nav1.7 channel, with an IC50 of 3.1 μM. It demonstrates analgesic efficacy in a complete Freund's adjuvant (CFA) inflammatory pain model and is applicable for pain relief research.

JC-171, a selective inhibitor of the NLRP3 inflammasome, effectively inhibits LPS/ATP-induced interleukin-1β (IL-1β) release from J774A.1 macrophages with an IC50 of 8.45 μM[1].

I-287 is a selective, orally active PAR2 inhibitor that functions as a negative allosteric modulator of Gαq and Gα12/13 activity and their downstream effectors. It has been shown to attenuate Complete Freund's adjuvant-induced inflammation in mice, suggesting its utility in inflammation/immunology research [1].

K 41498 is a selective peptide antagonist targeting both corticotropin-releasing factor receptor 2α (CRF2α) and CRF2β, demonstrating high affinity with Kis of 0.66 and 0.62 nM, respectively, in HEK293 cells expressing these human receptors. Its selectivity is evident as it exhibits a significantly reduced affinity for CRF1 receptor (Ki = 425 nM in HEK293 cells expressing the human CRF1 receptor). Additionally, K 41498, when administered intravenously at 1.84 µg/animal, effectively mitigates urocortin-induced hypotension in rats. Furthermore, its intrathecal delivery ranging from 0.075 to 0.5 µmol/animal significantly lowers the mechanical paw withdrawal threshold in a rat model, indicating its potential utility in managing nociception triggered by complete Freund's adjuvant.

[Leu144,Arg147]-PLP (139-151) is a mutated fragment of the myelin proteolipid protein (PLP), featuring substitutions of tryptophan to leucine and histidine to arginine at positions 144 and 147, respectively. Immunizing mice with this peptide (50 µg) mixed in complete Freund's adjuvant (CFA) elevates IL-4 levels in the spleen. While it suppresses Th1 cell activation in vitro, it does not do so in vivo; instead, it promotes the development of regulatory T cells. Preimmunization with [Leu144, Arg147]-PLP (139-151) postpones the onset of experimental autoimmune encephalomyelitis (EAE) triggered by encephalitogenic peptides from PLP (178-191), myelin oligodendrocyte glycoprotein (MOG) (92-106), or myelin basic protein (MBP) in mice.

Body Protection Compound 157 (BPC 157) is a pentadecapeptide derived from BPC, identified in gastric juice, exhibiting diverse biological activities. At 2 µg/ml, BPC 157 enhances primary rat tendon fibroblast cell migration and F-actin formation. Furthermore, doses of 0.01 and 10 µg/kg, intraperitoneally (i.p.), mitigate paw swelling, bone erosion, and mononuclear cell infiltration in the joints of rats with rheumatoid arthritis induced by complete Freund's adjuvant (CFA). It also diminishes gastric ulcer size in rats caused by indomethacin, aspirin, or diclofenac at these doses. Additionally, BPC 157 reduces catalepsy duration and tremor severity in a mouse model of Parkinson's disease triggered by MPTP.
