parathyroid hormone (7-34) [Homo sapiens] [Macaca fascicularis] is a peptide with the sequence H2N-LMHNLGKHLNSMERVEWLRKKLQDVHNF-OH, MW= 3474.03. Parathyroid hormone (PTH) is secreted by the chief cells of the parathyroid glands as a polypeptide containing
LBW242 is a 3-mer and Smac mimetic and is an effective and orally active proapoptotic IAP inhibitor. LBW242 has activity against multiple myeloma and potentiates TRAIL- and anticancer drug-mediated cell death of ovarian cancer cells. LBW242 displays effec
SBP-0636457 (SB1-0636457) is a SMAC mimetic and an inhibitor of inhibitor of apoptosis (IAP) proteins. It specifically binds to the BIR-domains of IAP proteins with a Ki value of 0.27 μM. SBP-0636457 holds potential for research in the fields of solid tumors and hematologic cancers.
CGP74514A is a CDK1 inhibitor with potential anticancer activity. In U937 cells, CGP74514A - induced apoptosis (5 microM) became apparent within 4 hr and approached 100% by 24 hr. The pan- caspase inhibitor Boc-fmk and the caspase-8 inhibitor lETD-fmk opposed CGP74514A -induced caspase-9 activation and PARP degradation, but not cytochrome c or Smac DIABLO release. CGP74514A -mediated apoptosis was substantially blocked by ectopic expression of full-length Bel- 2, a loop-deleted mutant Bcl-2, and Bcl-x(L). CGP74514A treatment (5 microM; 18 hr) resulted in increased p21(CIP1) expression, p27(KIP1) degradation, diminished E2F1 expression, and dephosphorylation of p34(CDC2). It also induced early (i.e., within 2 hr) inhibition of CDK1 activity and dephosphorylation of pRb, followed by pRb degradation, but did not block pRb phosphorylation at CDK2- and CDK4- specific sites. These findings indicate that the selective CDK1 inhibitor, CGP74514A , induces complex changes in cell cycle......
SM-164 Hydrochloride is a cell-permeable Smac mimetic compound. SM-164 binds to XIAP protein containing both the BIR2 and BIR3 domains(IC50 value of 1.39 nM) and functions as an extremely potent antagonist of XIAP.
Dimeric Smac mimetic; potent inhibitor of X-linked (XIAP) and cellular (cIAP) inhibitor of apoptosis protein (IC50 values are 15, 15 and 21 nM for XIAP, cIAP1 and cIAP2 respectively). Binds to the BIR3 domain of XIAP to prevent interaction with caspase-9. Causes degradation of cIAP1 and cIAP2 and induces apoptosis in MDA-MB-231 breast cancer cells. Causes tumor regression in MDA-MB-231 xenograft-bearing mice.
