PF 477736 Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Checkpoint kinase 1 (Chk1) regulates S and G₂-M phase cell cycle checkpoints in response to DNA damage. PF-477736 is an ATP-competitive inhibitor of Chk1 with a K_i value of 0.49 nM that demonstrates 100-fold selectivity over Chk2. When used in combination with various chemotherapeutics, PF-477736 abrogates DNA damage-induced cell cycle arrest, potentiating the antiproliferative effects of these compounds in tumor cell lines and xenografts.

• Verwenden

  PF-477736 has been used as a checkpoint protein 1 (CHK1) inhibitor to study the effect of CHK1 in cell cycle regulation in primary breast and lung primary epithelial cells.

• Verwenden

  P293850 is a selective checkpoint kinase 1 (Chk1) inhibitor (Ki values are 0.49 and 47 nM for Chk1 and Chk2 respectively). Abrogates cell cycle arrest at S and G2-M checkpoints; sensitizes cells to DNA damage.

• Definition

  ChEBI: PF-00477736 is a diazepinoindole that is 8-amino-4,5-dihydro-6H-[1,2]diazepino[4,5,6-cd]indol-6-one which is substituted at position 2 by a 1-methylpyrazol-4-yl group and in which the amino group at position 8 has undergone condensation with the carboxy group of (2R)-2-cyclohexylglycine to give the corresponding carboxamide. It is an inhibitor of checkpoint kinase 1 (Chk 1). It has a role as an EC 2.7.11.1 (non-specific serine/threonine protein kinase) inhibitor and an antineoplastic agent. It is an amino acid amide, a member of pyrazoles and a diazepinoindole.

• Biochem/physiol Actions

  PF-477736 may be effectively used to resensitize platinum resistant ovarian cancer cells. PF-477736 alone or in combination with other chemotherapeutic agents may be used to treat triple-negative breast cancer.
