ADC약물 개발 솔루션
ADC 약물의 삼 대 구성체는 바로: 1.이성 타깃 항체, 2. 독소, 3. 분해 가능/분해 불가능한 결합자입니다. 특이성 타깃을 식별과 효과적인 독소 작용을 갖고 있는 ADC는 명실상부한 '바이오 미사일'입니다. ADC 약물의 개발은 비교적 높은 기술 장벽이 있으니까 종합적으로 고려해야 합리적인 타깃을 선택하는 것입니다. 항체, 결합자, 소분자 약물 및 그들 사이의 합리적인 조합, 그리고 항체 결합 기술 및 ADC의 약물 내성 등 여러 요인등을 고려해야 합니다. 그중 표적점의 선택, 결합자의 선택, 결합기술 및 임상전의 약효평가는 ADC 연구개발과정에서 주목하는 초점입니다.>>> Download the ebook: Key point of ADCs design
