Peptídeos
Os peptídeos são cadeias curtas de aminoácidos ligados por ligações peptídicas, desempenhando papéis importantes como moléculas biológicas em processos celulares. Eles funcionam como hormônios, neurotransmissores e moléculas de sinalização, sendo amplamente utilizados em aplicações terapêuticas e diagnósticas. Os peptídeos também são cruciais na pesquisa para estudar interações proteicas, atividades enzimáticas e vias de sinalização celular. Na CymitQuimica, oferecemos uma ampla seleção de peptídeos de alta qualidade para apoiar suas necessidades de pesquisa e desenvolvimento em biotecnologia e farmacêutica.

Heat shock proteins (Hsps) are highly conserved and stress inducible. Hsp70 has been found in tumour cell lines to be highly expressed with a higher plasma membrane localisation. This is correlated to the cell sensitivity to natural killer (NK) cell-mediated lysis. Investigation identified that Hsp70 N-terminal extended peptide TKD (450-463) was critical for this to occur. TKD (450-463) with low dose interleukin (IL-2) has the same capacity to induce NK cell proliferation and activity as the full-length protein Hsp70. Excess of Hsp70 and TKD (450-463) both inhibit cytolytic activity by NK cells. Other related sequences tested did not lead to NK cell-mediated lysis. Further study with the TKD (450-463) epitope could elucidate how NK cells are activated by Hsp70s as the mechanism remains unclear.Peso molecular:1,562.8 g/molH-LPSEFDLSAFLR^-OH

Tos-Gly-Pro-Lys-pNA acetate
CAS:Tos-Gly-Pro-Lys-pNA acetate is a peptide that has been shown to have inhibitory effects on serine proteases, such as fibrinogen. Tos-Gly-Pro-Lys-pNA acetate binds to the active site of serine proteases, which inhibits their activity and prevents them from cleaving fibrinogen. The rate of reaction is dependent on the concentration of enzyme inhibitors. For example, at low concentrations, the enzyme inhibitor will bind to only one or two sites on the serine protease, while at high concentrations it may bind to many sites. This molecule has been shown to be a potent inhibitor of human immunodeficiency virus (HIV) protease and is currently being studied for its use as a potential antiviral agent.Fórmula:C26H34N6O7SPureza:Min. 95%Cor e Forma:PowderPeso molecular:574.65 g/molHXB2 gag NO-102/aa405 - 419

H-His-Ala-OH
CAS:H-His-Ala-OH is a peptide hormone that is derived from the amino acid histidine. It has been shown to be a potent inhibitor of tumor growth in human breast cancer tissue and human serum. H-His-Ala-OH inhibits the release of peptide hormones, such as insulin and glucagon. This compound also has anti-inflammatory properties, which may be due to its ability to inhibit the production of prostaglandins. H-His-Ala-OH interacts with collagen via a number of mechanisms, including inhibition of proteolytic enzymes and binding with collagenase. H-His-Ala-OH also binds to casein, which is found in milk. The interaction between casein and H-His-Ala-OH leads to an increase in systolic blood pressure in rats and mice.Fórmula:C9H14N4O3Pureza:Min. 95%Cor e Forma:PowderPeso molecular:226.23 g/molIFNB1 (118-132) Human
Recombinant human interferon-β (IFNB) is a therapeutic for certain stages of multiple sclerosis (MS). However, a significant portion of patients develop neutralising antibodies within 2 years and prevent clinical efficacy of the treatment, this was correlated to a specific rise in IgG. Sequencing of IFNB1 revealed a CD4+ T cell epitope residues (118-132) that contains critical T cell activation residues. The identification of this sequences can now allow it to be manipulated to hopefully provide new interferon treatments that reduces the capacity for induction of neutralising antibodies in MS patients. The IFNB1 (118-132) epitope can be used for immunological investigations such as T cell activation, antibody recognition via immunoassays and immunohistochemistry. This may provide further insights into certain haplotypes correlating to IFNB responses in MS treatment.Peso molecular:1,906.23 g/molH-DTLMISR^-OH

LRRK2 is a leucine rich repeat kinase 2. Increase in LRRK2 kinase activity due to mutation has been linked to numerous forms of Parkinson disease (PD). Theoretically, identification of suitable inhibitors of LRRK2 could be the basis for treatments of PD. Markers of LRRK2 activity and function are available that may be clinically relevant in the future as prognostic indicators. Nictide is a substrate model peptide for LRRK2 activity in in vitro kinase assay analysis. -LRRK2 phosphorylates Rab GTPases and alters their association with effector proteins leading to changes in a vast array of cellular functions including the immune response. The use of in vitro kinase assays with small molecules substrates makes screening for LRRK2 inhibitors possible. Alongside nictide, LRRKtide is also used in the same in vitro assays as a substrate model peptide for LRRK2.- Nictide and LRRKtide are available in our catalogue.Peso molecular:2,748.5 g/mol5Fam-CRGDK-OH

The Influenza Virus Nucleoprotein (311 - 325) is a component of the viral ribonucleotide complex, derived from the influenza virus and it is involved in viral replication, RNA packing and nuclear trafficking. As a monomer it contains basic residues which allow it to bind to single stranded RNA and through its flexible tail loop it has the ability to form NP oligomers.Furthermore NP is able to support the viral polymerase structurally, through associating with the two subunits PB1 and PB2, and it allows the viral ribonucleotide complex to be transported in and out of the nucleus due to its nuclear localisation and nuclear export signals.During influenza viral replication messenger RNA, viral genome RNA and complementary positive-sense RNA are produced and NP is crucial for this replication.Inhibitors of NP have potential to be used to prevent the influenza virus in humans.Peso molecular:1,764.9 g/molH-VPTTAASTPDAVDK^-OH

[5-FAM] EGFR/kinKDR peptide substrate
Peptide substrate of the epidermal growth factor receptor (EGFR), a member of the receptor tyrosine kinase family known as ErbBs or HER receptors. These receptors are involved in the regulation of cell proliferation, survival, differentiation and migration. When these receptors are dysregulated many diseases, including cancer, can arise.Binding to the ligand binding domain of the EGFR causes receptor dimerization. This is sequentially followed by the tyrosine kinase domain being activated and the tyrosine residues on the C-terminal tail of the receptor becoming phosphorylated, activating downstream signalling pathways.This peptide contains an N-terminal 5-Carboxyfluorescein (5-FAM) moiety, a widely used green fluorescent tag.Peso molecular:1,978.9 g/molLCBiot-PQDKEYYKVKE-OH

ACTH (7-38) Human
Segment 7-38 of adrenocorticotropic hormone (ACTH). ACTH, also known as corticotropin, is a cleavage product from a larger precursor proopiomelanocortin (POMC). This 39 amino acid-peptide hormone is produced in the anterior pituitary gland upon stimulation by the corticotropin releasing hormone from the hypothalamus in response to stress. It stimulates the secretion of steroid hormone, specifically glucocorticoids in the adrenal cortex by acting through a cell membrane receptor (ACTH-R). In mammals, the action of ACTH is limited to those areas of the adrenal cortex in which the glucocorticoid hormones cortisol (hydrocortisone) and corticosterone are formed. ACTH has little control over the secretion of aldosterone, the other major steroid hormone from the adrenal cortex.Peso molecular:3,659.11 g/molRecombinant Pseudomonas aeruginosa III protein PscF (pscF)

CAS:Amyloid beta peptide (Aβ) is a neurotrophic factor that is involved in the pathogenic mechanism of Alzheimer's disease. This drug inhibits the production of Aβ by binding to the enzyme, secretase. It has been shown that Aβ binds to a transporter protein and is transported into cells, where it accumulates in the cytoplasm. The physiological levels of Aβ are regulated by proteins called "gene chaperones" which prevent Aβ from aggregating into plaques. Dextran sulfate inhibits this process by binding to amyloid and preventing it from accumulating in the cytoplasm. Amyloid beta peptide trifluoroxalate (ATFX) has been shown to inhibit the production of Aβ with structural analysis, inhibition of cellular uptake and secretion, and inhibition of fibrillization. ATFX also has potential as a biomarker for Alzheimer's disease because it can be detected at low concentrations in urine or serumFórmula:C194H295N53O58S·C2HF3O2Pureza:Min. 95%Cor e Forma:White PowderPeso molecular:4,443.83 g/molAc-LVLRLR-OH
