Angiotensin II (human)
Angiotensin II (human)

Item number: Cay17150-25

Angiotensin II is a peptide hormone known best as a vasoconstrictor with central roles in chronic hypertension, heart failure, and stroke. It is an octapeptide typically generated by the removal of two residues from angiotensin I by angiotensin-converting enzyme (ACE). Angiotensin II is a ligand for at least two distinct receptors, AT1 and AT2, each evoking distinct...

AAF-CMK (trifluoroacetate salt)
AAF-CMK (trifluoroacetate salt)

Item number: Cay14461-5

Tripeptidyl peptidase II (TPPII) is a serine peptidase of the subtilisin-type which removes tripeptides from the free NH2 terminus of oligopeptides. AAF-CMK is an irreversible inhibitor of TPPII commonly used at 10-100 µM. It does not significantly interfere with the chymotrypsin-like activity of the proteasome. AAF-CMK also inhibits bleomycin hydrolase and...
Application: TPPII inhibitor, Bleomycin hydrolase and aminopeptidase inhibitor

Iberiotoxin
Iberiotoxin

Item number: Cay14608-100

Iberiotoxin, a peptide purified from venom of the scorpion B. tamulus, is a selective blocker of large-conductance calcium ion-activated potassium ion channels (BKCa). In single channel recordings, iberiotoxin can reversibly block outward currents mediated by BKCa in excised membrane patches from bovine aortic smooth muscle with an IC50 value of 250 pM. It is also a...

Apamin
Apamin

Item number: Cay17082-500

Apamin is an 18 amino acid peptide toxin found in bee venom. It is a potent blocker of small conductance Ca2+-activated K+ (SK, KCa2) channels that is more effective at SK2 than SK1 and SK3 (IC50 values are 0.06-0.4, 1-12, and 1-13 nM, respectively). It is ineffective against SK4 at 1 µM. Apamin is used to elucidate the roles of these channels in cells and tissues expressing...
Application: Bee venom toxin, KCa2 blocker

A-54556B
A-54556B

Item number: Cay17090-500

A-54556B is a natural acyldepsipeptide (ADEP) antibiotic isolated from the fermentation broth of S. hawaiiensis. Like the closely related ADEP, A-54556A (Cay-15305), A-54556B is effective against Gram-positive bacteria, including penicillin-resistant S. aureus. A-54556B is also effective against many strains of anaerobic bacteria.
Application: Gram-positive bacterial antibiotic

Enopeptin A
Enopeptin A

Item number: Cay17092-500

Enopeptin A, originally isolated from a culture broth of Streptomyces sp. RK-1051, is a depsipeptide antibiotic that contains two unusual amino acids (N-methylalanine and 4-methylproline) and features a pentaenone side chain. It is effective against Gram-positive bacteria, including methicillin-resistant S. aureus (MIC = 25 µg/ml), and Gram-negative bacteria, including...

Micrococcin P1
Micrococcin P1

Item number: Cay17093-500

Micrococcin P1 is a macrocyclic peptide antibiotic that functions as an acceptor-site-specific inhibitor of ribosomal protein synthesis, effectively preventing the growth of Gram-positive bacteria without affecting that of Gram-negative bacteria.
Application: Gram-positive bacterial antibiotic

Pyridomycin
Pyridomycin

Item number: Cay17095-500

Pyridomycin is a structurally unusual antimycobacterial cyclodepsipeptide whose composition includes two rare moieties: 3-(3-pyridyl)-L-alanine and 2-hydroxy-3-methylpent-2-enoic acid. It inhibits NADH-dependent enoyl (Acyl-Carrier-Protein) reductase InhA, preventing mycolic acid synthesis in M. tuberculosis, including isoniazid-resistant strains (MICs = 0.31-0.63 µg/ml).
Application: Antimycobacterial enoyl ACP reductase inhA inhibitor

alpha-Amanitin
alpha-Amanitin

Item number: Cay17898-1

alpha-Amanitin is a cyclic peptide found in several species of the Amanita genus as well as other poisonous fungi. At 1, 10, and 50 µg/ml, respectively, alpha-amanitin inhibits RNA polymerase II, III, and IV, preventing translocation of the enzymes on DNA, which significantly slows the rate of transcription. RNA polymerase I is insensitive to its effects. This toxin is used...

beta-Amanitin

Item number: Cay18142-1

beta-Amanitin is a cyclic peptide found in several species of the Amanita genus, as well as other poisonous fungi. It inhibits RNA polymerase II and III but not RNA polymerase I or bacterial RNA polymerase, thus preventing mammalian protein synthesis. The biological activity of this toxin is similar to that of alpha-amanitin (Cay-17898) but differs structurally by the...
