The present invention relates to novel imidazole derivatives which show an inhibitory activity against farnesyl transferase, pharmaceutically acceptable salts or isomers thereof and pharmaceutical compositions comprising such imidazole derivatives. More particularly, the present invention relates to intermediate compounds which are used in the preparation of the imidazole derivatives of the invention. Related processes also are disclosed.

Imidazole derivatives having an inhibitory activity for farnesyl transferase and process for preparation thereof

The present invention relates to a novel imidazole derivative represented by formula (1) which shows an inhibitory activity against farnesyl transferase or pharmaceutically acceptable salts or isomers thereof, in which A, n and Y are defined in the specification; to a process for preparation of the compound of formula (1); to intermediates which are used in the preparation of the compound of formula (1): and to a pharmaceutical composition comprising the compound of formula (1) as an active ingredient.

Farnesyl transferase inhibitors having a piperidine structure and process for preparation thereof

The present invention relates to a novel imidazole derivative represented by formula (1) which shows an inhibitory activity against farnesyl transferase or pharmaceutically acceptable salts or isomers thereof, in which A, n,and Y are defined in the specification; to a process for preparation of the compound of formula (1); to intermediates which are used in the preparation of the compound of formula (1); and to a pharmaceutical composition comprising the compound of formula (1) as an active ingredient.

A transgenic mouse whose genome comprises the H/K-ras 4B chimeric gene to form a mammary tumor and, particularly, the expression vector producing H/K-Ras 4B chimeric protein by using MMTV (mouse mammary tumor virus) promoter. This protein contains the first 164 amino acids of the H-Ras followed by the last 24 amino acids of K-Ras 4B. The second, it relates to the transgenic mouse expressing the H/K-Ras 4B protein with a mammary tumor, and the third, the method of preparation.
