Malformin C

Item number: Cay21613-1

Malformin C is a natural fungus-derived bicyclic pentapeptide that has antibacterial properties, particularly against species of Bacillus. Malformin C potently blocks the ability of bleomycin (Cay-13877) to induce G2 arrest in human T-cell leukemia-derived Jurkat cells (IC50 = 0.9 nM). It less potently abrogates...

Z-VAD(OMe)-FMK
Z-VAD(OMe)-FMK

Item number: Cay14463-5

Z-VAD(OMe)-FMK is a cell-permeable, competitive, and irreversible inhibitor of all caspases. Through this action, it inhibits cleavage of poly(ADP-ribose) polymerase, preventing apoptosis when used at 10-50 µM. It also blocks caspase-mediated apoptosis in vivo. Z-VAD(OMe)-FMK effectively prevents caspase action in...

Peptide YY (3-36)
Peptide YY (3-36)

Item number: Cay16502-1

Peptide YY (PYY) is a polypeptide that is released postprandially in proportion to meal energy content by endocrine L cells in the ileum and colon in order to regulate appetite. PYY, along with neuropeptide Y (NPY, Cay-15071), inhibits gastrointestinal motility and electrolyte secretion, which is thought to indicate...

Glucagon
Glucagon

Item number: Cay24204-1

Glucagon is a peptide hormone produced from proglucagon in pancreatic alpha cells that has a role in the regulation of glucose metabolism. Pulsatile application of glucagon to rat hepatocytes stimulates glucose production ex vivo. It also stimulates glucose output from perfused rat livers via increases in...

Orexin A (bovine, human, mouse, rat)
Orexin A (bovine, human, mouse, rat)

Item number: Cay15073-500

Orexin A is a 33 amino acid hypothalamic neuropeptide with a role in appetite regulation, wakefulness, locomotor activity, hypothalamic-pituitary-adrenal activity, and pain thresholds. Orexin signaling is activated by nutrient depletion, causing an increase in food intake by delaying the signals of satiety. It...

Item number: Cay17598-25

3,3',5'-Triiodo-L-thyronine, also known as reverse T3 (rT3), is a thyroid hormone generated by deiodination of the prohormone thyroxine. It is about 1,000-fold less active at the thyroid hormone receptors TRalpha and TRbeta than 3,3',5-triiodo-L-thyronine (Cay-16028) and commonly described as inactive. However, high...
