Zusammenfassung:The present invention relates to a composition for enhancing sensitivity to radiotherapy, which comprises a novel compound inhibiting focal adhesion tyrosine kinase (FAK) protein as a target. More particularly, the present invention relates to a composition for enhancing radiotherapy and a pharmaceutical composition for preventing or treating cancer, which comprises a novel FAK inhibitor suppressing phosphorylation of FAK or Src and inhibiting activity thereof. The composition comprising a novel FAK inhibitor or a pharmaceutically acceptable salt thereof as an active ingredient according to the present invention reduces phosphorylation of FAK or Src to inhibit activity thereof, and induces destruction of cancer cells to treat cancer cells. Particularly, the composition is effective for enhancing sensitivity to radiotherapy and thus can be administered in combination with radiation exposure upon treatment of cancer to maximize the effect of radiotherapy. 본 발명은 FAK(Focal Adhesion tyrosine Kinase) 단백질을 표적으로 억제하는 신규 화합물을 유효성분으로 포함하는, 방사선 민감성 증진용 조성물에 관한 것으로, 보다 구체적으로, FAK 또는 Src의 인산화를 저해하여 그의 활성을 억제시키는 신규 FAK 저해제를 유효성분으로 포함하는 방사선 민감성 증진용 조성물 및 암 예방 또는 치료용 약학적 조성물에 관한 것이다. 본 발명의 신규 FAK(Focal Adhesion tyrosine Kinase) 저해제 혹은 이의 약학적으로 허용 가능한 염을 유효성분으로 포함하는 조성물은 FAK 또는 Src의 인산화를 감소시켜 그의 활성을 억제하고 암 세포의 사멸을 유도함으로써 암세포를 치료하고, 특히, 방사선에 대한 민감성을 증가시키는 효과가 있어 암의 치료시 방사선 조사와 병용으로 투여하여 그 효과를 극대화시킬 수 있다.
