Abstract: The present invention relates to novel tricyclic derivative compounds, and more specifically to tricyclic derivative compounds, optical isomers thereof, racemates thereof, or pharmaceutically acceptable salts thereof, which have excellent activity against PARP-1, tankyrase-1 or tankyrase-2. The tricyclic derivative compounds, optical isomers thereof, racemates thereof or pharmaceutically acceptable salts thereof according to the present invention have inhibitory activity against PARP-1, tankyrase-1, or tankyrase-2, and thus can be effectively used for the prevention or treatment of neuropathic pain, neurodegenerative diseases, cardiovascular diseases, diabetic neuropathy, inflammatory diseases, osteoporosis, or cancer.

Abstract: The present invention relates to a novel tricyclic derivative with efficient inhibitory activity against poly(ADP-ribose)polymerases (PARP) or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition containing the same. The tricyclic derivative of the invention is useful for the prevention or treatment of diseases caused by excess PARP activity, especially neuropathic pain, neurodegenerative diseases, cardiovascular diseases, diabetic nephropathy, inflammatory diseases, osteoporosis, and cancer, by inhibiting the activity of poly(ADP-ribose)polymerases.

Abstract: The present invention relates to tricyclic derivatives or pharmaceutically acceptable salts thereof, their preparations and pharmaceutical compositions containing them. More precisely, the present invention relates to tricyclic derivatives as colchicine derivatives, pharmaceutically acceptable salts thereof, their preparations and pharmaceutical compositions containing them. Tricyclic derivatives of the present invention show very powerful cytotoxicity to cancer cell lines but were much less toxic than colchicine or taxol, confirmed through animal toxicity test. Tricyclic derivatives of the invention also decrease the volume and weight of a tumor and have a strong angiogenesis inhibiting activity in HUVEC cells. Thus, tricyclic derivatives of the present invention can effectively be used as an anticancer agent, anti-proliferation agent and an angiogenesis inhibitor.
