Definitions

  • the present invention relates to compounds which are inhibitors of the activity of one or more of the isoforms of the serine/threonine kinase, Akt (also known as PKB; hereinafter referred to as "Akt").
  • Akt serine/threonine kinase
  • the present invention also relates to pharmaceutical compositions comprising such compounds and methods of using the instant compounds in the treatment of cancer.
  • Apoptosis (programmed cell death) plays essential roles in embryonic development and pathogenesis of various diseases, such as degenerative neuronal diseases, cardiovascular diseases and cancer. Recent work has led to the identification of various pro- and anti-apoptotic gene products that are involved in the regulation or execution of programmed cell death.
  • anti-apoptotic genes such as Bcl2 or Bcl-xL
  • pro-apoptotic genes such as Bax or Bad
  • the execution of programmed cell death is mediated by caspase-1 related proteinases, including caspase-3, caspase-7, caspase-8 and caspase-9 etc (Thornberry et al. Science, 281 : 1312-1316 (1998)).

  • Akt serine/threonine kinase
  • Aktl/ PKBa Three members of the Akt subfamily of second-messenger regulated serine/threonine protein kinases have been identified and termed Aktl/ PKBa, Akt2/PKB , and Akt3/PKBy (hereinafter referred to as "Aktl”, “Akt2” and "Akt3"), respectively.
  • the isoforms are homologous, particularly in regions encoding the catalytic domains. Akts are activated by phosphorylation events occurring in response to PI3K signaling.
  • PI3K phosphorylates membrane inositol phospholipids, generating the second messengers phosphatidyl-inositol 3,4,5-trisphos- phate and phosphatidylinositol 3,4-bisphosphate, which have been shown to bind to the PH domain of Akt.
  • the current model of Akt activation proposes recruitment of the enzyme to the membrane by 3'-phosphorylated phosphoinositides, where phosphorylation of the regulatory sites of Akt by the upstream kinases occurs (B.A. Hemmings, Science 275:628-630 (1997); B.A. Hemmings, Science 276:534 (1997); J. Downward, Science 279:673-674 (1998)).
  • Aktl Phosphorylation of Aktl occurs on two regulatory sites, Thr308 in the catalytic domain activation loop and on Ser473 near the carboxy terminus (D. R. Alessi et al. EMBO J. 15:6541-6551 (1996) and R. Meier et al. J. Biol. Chem. 272:30491-30497 (1997)).
  • Equivalent regulatory phosphorylation sites occur in Akt2 and Akt3.
  • the upstream kinase which phosphorylates Akt at the activation loop site has been cloned and termed 3'-phosphoinositide - dependent protein kinase 1 (PDK1).
  • PDK1 phosphorylates not only Akt, but also p70 ribosomal S6 kinase, p90RSK, serum and glucocorticoid-regulated kinase (SGK), and protein kinase C.
  • the upstream kinase phosphorylating the regulatory site of Akt near the carboxy terminus has not been identified yet, but recent reports imply a role for the integrin-linked kinase (ILK-1), a serine/threonine protein kinase, or autophosphorylation.
  • ILK-1 integrin-linked kinase
  • serine/threonine protein kinase or autophosphorylation.
  • Akt2 is overexpressed in a significant number of ovarian (J. Q. Cheng et al. Proc. Natl. Acad. Sci. U.S.A. 89:9267- 9271(1992)) and pancreatic cancers (J. Q. Cheng et al. Proc. Natl. Acad. Sci. U.S.A. 93 :3636- 3641 (1996)).
  • Akt3 was found to be overexpressed in breast and prostate cancer cell lines (Nakatani et al. J. Biol. Chem. 274:21528-21532 (1999).
  • the tumor suppressor PTEN a protein and lipid phosphatase that specifically removes the 3' phosphate of Ptdlns(3,4,5)-P3, is a negative regulator of the PI3K/Akt pathway (Li et al. Science 275: 1943-1947 (1997), Stambolic et al. Cell 95:29-39 (1998), Sun et al. Proc. Natl. Acad. Sci. U.S.A. 96:6199-6204 (1999)).
  • Germline mutations of PTEN are responsible for human cancer syndromes such as Cowden disease (Liaw et al. Nature Genetics 16:64-67 (1997)).
  • PTEN is deleted in a large percentage of human tumors and tumor cell lines without functional PTEN show elevated levels of activated Akt (Li et al. supra, Guldberg et al. Cancer Research 57:3660-3663 (1997), Risinger et al. Cancer Research 57:4736-4738 (1997)).
  • Akt activation and activity can be achieved by inhibiting PI3K with inhibitors such as LY294002 and wortmannin.
  • inhibitors such as LY294002 and wortmannin.
  • PI3K inhibition has the potential to indiscriminately affect not just all three Akt isozymes but also other PH domain-containing signaling molecules that are dependent on Pdtlns(3,4,5)-P3, such as the Tec family of tyrosine kinases.
  • Akt can be activated by growth signals that are independent of PI3K.
  • Akt activity can be inhibited by blocking the activity of the upstream kinase PDK1. No specific PDK1 inhibitors have been disclosed.
  • inhibition of PDK1 would result in inhibition of multiple protein kinases whose activities depend on PDK1, such as atypical PKC isoforms, SGK, and S6 kinases (Williams et al. Curr. Biol. 10:439-448 (2000).
