amyloid-b peptide

Amyloid β Peptide (42-1)(human) acetate is the inactive form of Amyloid β Peptide (1-42). Amyloid β Peptide (42-1)(human) acetate is a 42-amino acid peptide which plays a key role in the pathogenesis of Alzheimer disease.

Small Cardioactive Peptide B SCPB acetate (Small Cardioactive Peptide B SCPB acetate (84746-43-0 free base)) is a neurally active peptide, stimulates adenylate cyclase activity in particulate fractions of both heart and gill tissues with EC50s of 0.1 and 1.0 μM, respectively.

Thioether-cyclized helix B peptide (CHBP) enhances metabolic stability and exerts renoprotective effects by promoting autophagy through the inhibition of mTOR C1 and activation of mTOR C2 [1].

Amyloid-Forming peptide GNNQQNY, a biologically active heptapeptide derived from the N-terminal prion-determining domain of yeast Sup35, is instrumental in amyloid fibril formation. Its atomic oligomeric structure has been detailed, serving as an excellent model for investigating early-stage aggregation. The peptide can form three stable β-sheet structures: in-register parallel, off-register parallel, and anti-parallel. Notably, the in-register parallel dimer aligns closely with amyloid β-sheet architecture, relying on fewer interpeptide hydrogen bonds and emphasizing hydrophobic interactions, which enhances conformational entropy relative to the anti-parallel arrangement.

Small Cardioactive Peptide B (SCPB), a neurally active peptide, stimulates adenylate cyclase activity in particulate fractions of both heart and gill tissues with EC50s of 0.1 and 1.0 μM, respectively.

Peptide B, Bovine, an immunoregulatory peptide derived from αs1-casein B-8P (f1-13) in bovine milk, is predominantly generated during maturation and exhibits antihypertensive effects [1] [2].

Thioether-cyclized helix B peptide, CHBP (TFA), is the trifluoroacetic (TFA) salt of CHBP. This form enhances metabolic stability and exhibits renoprotective effects by promoting autophagy, achieved through the inhibition of mTOR C1 and activation of mTOR C2 [1].

Amyloid-β (25-35) (Aβ (25-35)) is an 11-residue fragment of the Aβ protein that retains the physical and biological characteristics of the full length peptide. It forms fibrils that react to thioflavin T and Congo red and are organized in a cross-β arrangement of β-strands similar to Aβ (1-40) and Aβ (1-42) fibrils. Aggregated Aβ (25-35) decreases the viability of rat adrenal PC12 cells. It also decreases the viability of primary rat cortical neurons at concentrations ranging from 1 nM to 30 μM. In vivo, intracerebral injection of Aβ (25-35) (20 nmol) in rats induces lesions of neuronal and tissue loss. Aggregated Aβ (25-35) administered intracerebroventricularly to rats induces learning and memory impairments in the Y-maze, novel object recognition, and contextual fear conditioning tests.

SP-B peptide is an antimicrobial agent with antifungal activity demonstrated against Cryptococcus neoformans, Candida albicans, and Aspergillus fumigatus strains[1].

β-Amyloid peptide(16-20), with the amino acid sequence (KLVFF) derived from Amyloid-β (Abeta), functions as an efficient inhibitor of Abeta fibril formation. This compound is modified with RG-/-GR-NH2 residues at both its N- and C-terminal ends to enhance solubility [1].

Amyloid precursor c-terminal peptide has the amino acid sequence Gly-Tyr-Glu-Asn-Pro-Thr-Tyr-Lys-Phe-Phe-Glu-Gln-Met-Gln-Asn. APP is best known as the precursor molecule whose proteolysis generates beta-amyloid (Aβ), a 37 to 49 amino acid peptide whose am

GSNKGAIIGLM(131602-53-4(free base)) (Amyloid beta-peptide(25-35)) is the fragment Aβ(25-35) of the Alzheimer's amyloid β-peptide.
