Drugs containing enzyme inhibitors as the active ingredient

摘要

Drugs capable of selectively inhibiting the proliferation or metabolism of target cells such as cancer cells without affecting normal cells. Such a drug contains as the active ingredient an enzyme inhibitor and satisfies the following requirements: 1) the enzyme inhibitor being capable of inhibiting at least one enzyme essentially required in the first metabolic pathway of a compound essentially required in the survival of cells (i.e., an essential compound); 2) the essential compound being metabolizable in a second pathway which is different from the first pathway and not inhibited by the enzyme inhibitor; and 3) at least one enzyme essentially required in the second metabolic pathway lacking its function in the target cells the proliferation of which is to be inhibited by the drug.
