- 10. The compound of claim 1 which is
- 11. The compound of claim 1 which is
- 12. The compound of claim 1 which is
- 13. The compound of claim 1 which is
- 14. The compound of claim 1 which is
- 15. The compound of claim 1 which is
- 16. The compound of claim 1 which is
- 17. The compound of claim 1 which is
- 18. The compound of claim 1 which is
- 19. The compound of claim 1 which is
- 20. A method for inhibiting the abnormal growth of tumor cells expressing an activated ras oncogene by inhibition of ras farnesyl protein transferase in a mammal comprising administering to a mammal in need thereof an effective amount of a compound of claim 1.
- 21. The method of claim 20 wherein the cells inhibited are pancreatic tumor cells, lung cancer cells, myeloid leukemia tumor cells, thyroid follicular tumor cells, myelodysplastic tumor cells, epidermal carcinoma tumor cells, bladder carcinoma tumor cells or prostate tumor cells, breast tumor cells or colon tumors cells.
