    • Patent Number:
      9,421,203
    • Appl. No:
      14/564186
    • Application Filed:
      December 09, 2014
    • نبذة مختصرة :
      The invention provides methods for overriding cell cycle arrest in a tumor cell, which comprise inducing DNA damage in the cell, and contacting the cell with an amount of bosutinib or a bosutinib isomer effective to inhibit one or more kinase constituents of a DNA damage checkpoint pathway. The invention also provides novel bosutinib isomers, as well as compositions of the novel isomers and the bosutinib isomer 3,5-dichloro-4-methoxyaniline.

    • Claim:
      1. A method for treating a tumor in a subject in need thereof, comprising inducing DNA damage in a cell of the tumor, and administering to the subject an effective amount of a bosutinib isomer of Formula II: [chemical expression included] (II), or a pharmaceutically acceptable salt thereof, thereby treating the tumor.
    • Claim:
      2. The method of claim 1 , wherein inducing DNA damage in the cell comprises irradiating the cell in the subject.
    • Claim:
      3. The method of claim 1 , wherein inducing DNA damage in the cell comprises administering to the subject an effective amount of an agent that damages DNA.
    • Claim:
      4. The method of claim 3 , wherein the agent comprises an alkylating agent.
    • Claim:
      5. The method of claim 3 , wherein the agent comprises a pyrimidine analog.
    • Claim:
      6. The method of claim 3 , wherein the agent comprises gemcitabine.
    • Claim:
      7. The method of claim 1 , wherein the tumor is a tumor of the pancreas, lung, head and neck, kidney, hematopoietic system, breast, ovary, colon, lymph nodes, bladder, prostate gland, stomach, or esophagus.
    • Claim:
      8. The method of claim 6 , wherein the bosutinib isomer of Formula II reduces the LC 50 of gemcitabine to less than about 10 nM.
    • Claim:
      9. The method of claim 6 , wherein the bosutinib isomer of Formula II reduces the LC 50 of gemcitabine to less than about 5 nM.
    • Claim:
      10. The method of claim 6 , wherein the bosutinib isomer of Formula II reduces the LC 50 of gemcitabine to about 3 nM or less.
    • Claim:
      11. A method for treating a tumor in a subject in need thereof, comprising inducing DNA damage in a cell of the tumor, and administering to the subject an effective amount of a bosutinib isomer of Formula IV: [chemical expression included] (IV), or a pharmaceutically acceptable salt thereof, wherein each of R 1 and R 3 is independently selected from the group consisting of F, Br, and I, and wherein R 2 is selected from the group consisting of H and N, thereby treating the tumor.
    • Claim:
      12. The method of claim 11 , wherein inducing DNA damage in the cell comprises irradiating the cell in the subject.
    • Claim:
      13. The method of claim 11 , wherein inducing DNA damage in the cell comprises administering to the subject an effective amount of an agent that damages DNA.
    • Claim:
      14. The method of claim 13 , wherein the agent comprises an alkylating agent.
    • Claim:
      15. The method of claim 13 , wherein the agent comprises a pyrimidine analog.
    • Claim:
      16. The method of claim 13 , wherein the agent comprises gemcitabine.
    • Claim:
      17. The method of claim 11 , wherein the tumor is a tumor of the pancreas, lung, head and neck, kidney, hematopoietic system, breast, ovary, colon, lymph nodes, bladder, prostate gland, stomach, or esophagus.
    • Claim:
      18. The method of claim 1 , wherein the tumor is a tumor of the pancreas.
    • Claim:
      19. The method of claim 6 , wherein the tumor is a tumor of the pancreas.
    • Claim:
      20. The method of claim 11 , wherein the tumor is a tumor of the pancreas.
    • Claim:
      21. The method of claim 16 , wherein the tumor is a tumor of the pancreas.
