Leupeptin hemisulfate anhydrous
CAS:Leupeptin is a protease inhibitor that inhibits the activity of proteases in cells. It has been shown to inhibit transcriptional regulation and apoptosis pathway, as well as possessing anti-inflammatory properties. Leupeptin has been shown to have inhibitory properties against a variety of proteases, including group P2 metalloproteases, cathepsin D, and proteinase 3. This drug has also been shown to prevent neuronal death in experimental models by inhibiting cell lysis. Leupeptin binds to the active site of the enzyme by forming hydrogen bonds with conserved amino acid residues and steric interactions with nearby amino acid residues. The redox potentials of leupeptin are not known, but it is assumed that they are low enough for its antioxidant properties to be effective.

C5a receptor 2 (C5aR2, or C5L2) is a seven transmembrane non-G-protein-signalling receptor which binds the complement activation peptide C5a ligand. The complement cascade is a highly sophisticated network of innate immune proteins that are activated in response to invading pathogens or tissue injury. C5aR2 regulates the release of certain cytokines and is involved in a number of inflammatory conditions. C5aR2 can recruit and form a complex with β-arrestins, which can modulate ERK1/2 signalling in macrophages and neutrophils. C5aR2 has both pro- and anti-inflammatory actions. P32 is a functionally selective C5aR2 ligand which is able to recruit β-arrestin 2 with high efficacy, inhibit C5a-induced ERK1/2 activation and can selectively inhibit LPS-induced IL-6 release from human monocyte-derived macrophages (HMDMs). Functionally selective ligands for C5aR2 such as this are novel tools that can selectively modulate C5a activity and are therefore valuable tools in investigating C5aR2 function.Peso molecolare:1,118.5 g/molLCBiot-NLRKSGTLGHPGSL-OH

TAT-GluR23Y is a cell penetrating peptide that inhibits phosphorylation of AMPA receptor endocytosis.Recent studies have shown that AMPA receptor endocytosis, which is a cellular mechanism underlying the formation of LTD, plays a critical role in facilitating initial extinction of learned fear. Tat-Glur23Y can block regulated AMPA and thereby prevents long-term depression (LTD) in structures such as the nucleus accumbens and dorsal hippocampus.Peso molecolare:2,632.4 g/mol(Gln²²,Asn²³)-Amyloid β-Protein (1-40)
CAS:Custom research peptide; min purity 95%. For different specs please use the Peptide Quote Tool
Formula:C194H297N55O56SPeso molecolare:4,327.9 g/molTAT-CN21
TatCN21 is an inhibitor peptide for the calcium/calmodulin-dependent protein kinase II (CaMKII), a ubiquitously-expressed multifunctional serine/threonine protein kinase. TatCN21 blocks both autonomous and stimulated CaMKII activity with high selectivity. CaMKII is highly expressed in brain tissue where it regulates several processes including: neurotransmitter synthesis/release, neuronal plasticity- excitability and calcium homeostasis. Glutamate clearance by astrocytes is an essential part of normal excitatory neurotransmission, and accumulation of glutamate in the central nervous system is associated with many neurodegenerative disorders. CaMKII regulates glutamate homeostasis: CaMKII inhibition results in diminished glutamate uptake, dysregulated calcium homeostasis, release of the gliotransmitter ATP and compromise neuronal survival. Loss of CaMKII signalling may be an important factor in excitotoxicity. Peptide was obtained by linking the 11 amino acid human HIV Tat transporter to a 21 amino acid sequence corresponding to the CN21.

Formula:C184H277N51O56SPeso molecolare:4,131.6 g/molTAT-AKAP79 (326-336) scrambled amide
The activation of transient receptor potential cation channel subfamily V member 1 (TRPV1) is believed to play a role in hyperalgesia, asthma and hypertension. TRPV1 is important for neuronal pain detection as well as the detection of heat, capsaicin, protons and the neurotransmitter anandamide.- The scaffold protein AKAP79 targets kinases to phosphorylate TRPV1, however it has been shown that inflammatory intermediates prostaglandin-E2 or bradykinin can activate these kinases creating a route for inflammation to cause hyperalgesia.This product is composed of the TRPV1 interacting residues of AKAP79 reordered into a scrambled sequence and conjugated to the cell penetrating TAT domain at the N-terminus. The scrambled peptide was shown in vivo to have no effect on TRPV1 algesia and thus is a vital control for research work. This product is a vital tool for research into suitable TRPV1 antagonists. The scrambled-TAT peptide is available for purchase in both an acid and amide form, this is the C-terminal amide form.

The native form of GLP-1 in humans is the GLP-1 (7-36) amide. GLP-1 (7-36) amide is highly unstable (half-life <-2 minutes) due to proteolytic degradation by the serine protease, dipeptidyl peptidase-IV (DPP-IV). DPP-IV cleaves the N-terminal histidine and alanine residues from GLP-1 to generate two equipotent forms: GLP-1 (9-37) and GLP-1 (9-36) amide. This degradation mitigates against the therapeutic use of GLP-1 itself, therefore DPP-IV-resistant peptide analogues have been developed and licensed for clinical use. Contains an N-terminal biotin tag for easy detection and purification.

CAS:Tumour antigens recognised by cytotoxic T cells (CTLs) are a keen area of research to develop antigen-specific cancer therapies. However, hurdles are weak immunogenicity and high rates of degradation in vivo. In the search for a melanoma vaccine, the human tumour antigen Melan-A/MART-1 (27-35) has been used as a model to design peptides with improved characteristics for use in anti-tumour vaccines. The epitope can induce the production of melanoma-specific CD8+ T-cell responses. It has been included in melanoma antigen peptide vaccines, clinical trial data suggest that MART-1 (27-35) in human systems alongside other epitopes does affect the cellular and humoral responses, but much more work is required with this peptide to optimise it for clinical efficacy against melanoma.An alternate route that is possible but less studied is using MART-1 (27-35) to isolate CD8(+) T-cell clones with greater recognition for the epitope due to the contact with the T-cell receptor. This suggests melanomas could be targeted by optimising the T-cell receptor-peptide recognition of the T-cell repertoire by enhancing antigen targeting.Formula:C37H67N9O11Peso molecolare:813.98 g/molH-SDGPVKV^-OH

Keratin-Derived anti-microbial Peptides (KDAMPs), are peptide fragment of the intermediate filament protein cytokeratin 6A. They were originally isolated from lysates of human corneal epithelial cells. KDAMPs exhibit coil structures with low α-helical content and are smaller and more stable than other known host-expressed anti-microbials.Multiple length KDAMPs have been studied for their anti-microbial properties, and different fragments show different anti-microbial spectrums. The 19 mer KDAMP peptide is rapidly bactericidal against multiple clinical isolates of Pseudomonas aeruginosa, and shows even greater activity against-Streptococcus pyogenes. However it is not active against Staphylococcus aureus-or-Escherichia coli.

Residues 17-29 of the LL-37 peptide, also known as FK-13. FK-13 has near-similar anti-microbial and anti-cancer properties to LL-37. This core fragment also contains part of the LL-37 actin binding domain and can associate weakly with actin, actin binding protects this fragment from protease degradation.LL-37 is a member of the large cationic family of anti-microbial peptides called cathelicidins which have broad-spectrum anti-microbial activity and are expressed in many species. The only cathelicidin found in humans is LL-37- this is produced in epithelial cells, by proteolytic cleavage from the C-terminal of the hCAP-18 protein. LL-37 can be processed into several different forms of anti-microbial peptides. As well as its anti-microbial properties LL-37 also has anti-cancer properties and regulates many aspects of the innate immune system- overexpression of LL-37 has been linked to autoimmune diseases such as asthma and psoriasis.Peso molecolare:1,719.09 g/molH-IALILEPICCQERAA-OH

Apelin (65-76), human is derived from the apelin peptide which acts as a ligand for the apelin receptor (APJ) G protein coupled receptor and is a substrate for angiotensin converting enzyme 2. Preprapelin, encoded for by APLN located on Xq25-26.1, is cleaved to form either apelin 36 or apelin 17, 12 and 13. As a member of the adipokine hormone family, which are involved in processes such as vascular homeostasis and angiogenesis, the apelin is secreted from adipose tissue.Apelin has been found to be expressed in the spinal cord and the human brain and when performing immunohistochemistry it was observed that apelin-17 is significantly expressed in the human heart, brain, lungs and endothelial cells.Both apelin and the apelin receptor are widely distributed around the body thus apelin has been found to be associated with cardiovascular diseases, obesity, diabetes and cancer. Studies exploring myocardial infarction showed there to be greater apelin mRNA expression during human heart failure compared to in healthy tissue. Apelin protects against heart failure due to, the pyroglutamyl form of apelin, playing a role in decreasing infarct size of myocardial infarctions. Furthermore in rats with hypertension, the expression of apelin and APJ was decreased.Peso molecolare:1,402.8 g/molNeurotensin
Neurotensin (NT) is involved in food absorption in the gut as well as acting as a neurotransmitter in the central nervous system (CNS). In the intestine, NT increases fatty acid translocation, in part by increasing intestinal blood flow. In the CNS, NT regulates pathways associated with ghrelin and leptin which mediate satiety and food ingestion. NT is also involved in the regulation of Luteinizing hormone (LH) and Prolactin release and also plays a role in hypotension- analgesia- gut contraction- vascular permeability- maintaining energy homeostasis- fat storage and metabolic disorders. Higher plasma pro-NT levels are associated with obesity and insulin resistance. NT is therefore a potential target for treating obesity-related diseases.NT is secreted from neuroendocrine cells in the small intestine upon fat intake and exerts its physiological actions by binding three NT receptor (NTR) types- NTR1, NTR2, and NTR3.NTR1 is highly expressed in various tumour cells including- small cell carcinoma/small cell lung cancer (SCLC)- meningiomas- astrocytomas- glioblastoma- pancreatic and colonic carcinoma, and breast and prostate cancers. NTR1 is therefore a possible target for novel cancer therapy.
