    • The present invention provides 2-piperidone compounds or pharmaceutically acceptable salts thereof, which have a potent activity of inhibiting the proliferation of tumor cells and thus are useful as medicaments, as well as antitumor agents containing these compounds. The 2-piperidone compound is represented by the following formula (I): wherein R1 represents —(CH2)nR1a {wherein n is an integer of from 0 to 5, and R1a represents amino, lower alkylamino, di(lower alkyl)amino, substituted or unsubstituted aryl, or a substituted or unsubstituted heterocyclic group}, and R2 and R3 independently represent lower alkyl which may be substituted by lower alkoxycarboyl; lower alkenyl, aralkyl or lower alkynyl which may be substituted by substituted or unsubstituted aryl or a substituted or unsubstituted heterocyclic group; substituted or unsubstituted aryl; or a substituted or unsubstituted heterocyclic group.
    • 本发明提供了具有抑制肿瘤细胞增殖的有效活性的2-哌啶酮化合物或其药学上可接受的盐,因此可用作药物,以及含有这些化合物的抗肿瘤剂。 2-哌啶酮化合物由下式(I)表示:其中R1表示 - (CH2)nR1a {其中n为0-5的整数,R1a表示氨基,低级烷基氨基,二(低级烷基)氨基,取代的 或未取代的芳基,或取代或未取代的杂环基},R2和R3独立地表示可以被低级烷氧基羰基取代的低级烷基; 可被取代或未取代的芳基或取代或未取代的杂环基取代的低级烯基,芳烷基或低级炔基; 取代或未取代的芳基; 或取代或未取代的杂环基。
