p53 tumor suppressor fragment (232-240) is a peptide with the sequence H2N-Lys-Tyr-Met-Cys-Asn-Ser-Ser-Cys-Met-OH, MW= 1066.3. p53 is a tumor suppressor protein that in humans is encoded by the TP53 gene. p53 is crucial in multicellular organisms, where i

Several different arachidonoyl amino acids, including N-arachidonoyl-L-alanine (NALA), have been isolated and characterized from bovine brain. The glycine congener (NAGly) was further characterized and found to suppress formalin-induced pain in rats. NALA may have activity at cannabinoid receptor and/or VR1, but has not been fully characterized to date.

Several different arachidonoyl amino acids, including N-arachidonoyl-3-hydroxy-γ-aminobutyric acid (NAG-3H-ABA), have been isolated and characterized from bovine brain. The glycine congener was further characterized and found to suppress formalin-induced pain in rats. NAG-3H-ABA was also found in rat brain by LC-MS techniques, but has not been fully characterized to date. Most arachidonoyl amino acids are poor ligands for the CB1 receptor.

IKKγ NBD Inhibitory Peptide TFA is a specific NF-κB inhibitor that hinders the interaction between the IKKγ NEMO-binding domain (NBD) and IKKα and IKKβ, effectively preventing TNF-α-induced NF-κB activation. It has been demonstrated to significantly suppress inflammation and improve neurological deficits induced by cerebral ischemia [1] [2] [3].

Obestatin(human) TFA, an endogenous peptide originating from the same prepropeptide as ghrelin, is known to suppress food intake and reduce weight gain in rats.

Cyclic PSAP peptide (DWLPK) possesses properties akin to those of a therapeutic agent, demonstrating the potential to inhibit metastasis and suppress tumor growth in vivo [1].

Tertiapin LQ, a peptide derivative of honeybee venom peptide tertiapin, acts as an inhibitor of inwardly rectifying potassium (Kir) channels. Specifically, it targets and inhibits heteromultimeric potassium channels, including those formed by GIRK1 (also known as Kir3.1) and GIRK4 (Kir3.4), as well as inward-rectifier potassium channel 1 (Kir1.1). Its efficaciousness extends to in vivo applications, where it has been observed to suppress the Purkinje cell pause response to conditional stimuli in ferrets.

Somatostatin, also known as growth hormone-inhibiting hormone, is a naturally-occurring peptide hormone of 14 or 28 amino acid residues that regulates the endocrine system. It is secreted by the D cells of the islets to inhibit the release of insulin and

Tkip is a specific inhibitor of JAK2. It binds to the autophosphorylation site of JAK2, thereby inhibiting JAK2 autophosphorylation and the phosphorylation of the IFN-γ receptor subunit IFNGR-1. Tkip can suppress the antiviral activity of IFN-γ and the expression of MHC class I molecules. Tkip is applicable in studies related to the IFN-γ signaling pathway.

PIYLGGVFQ is a TNF-α peptide inhibitor. It can suppress TNF-α-mediated apoptosis, nuclear translocation, and activation of NF-κB. In a CIA mouse model, PIYLGGVFQ has demonstrated anti-arthritic activity.

Peptide P60 acts as a FOXP3 inhibitor. This compound can penetrate cells to hinder FOXP3's nuclear translocation and diminish its ability to suppress transcription factors NF-κB and NFAT. Peptide P60 also suppresses the immunosuppressive activity of regulatory T cells (Treg) derived from mice and humans, while enhancing effector T cell stimulation in vitro. Moreover, Peptide P60 can induce a lymphoproliferative autoimmune syndrome, displaying pathological characteristics similar to those observed in scurfy mice lacking functional Foxp3. Additionally, Peptide P60 has the potential to boost the immunogenicity of cancer and viral vaccines.
