Description of CB-5083

CB-5083은 IC50 값이 11nM인 고선택적이고 경구 투여가 가능한 AAA-ATPase p97 억제제이다. P97은 오접힌 단백질을 제거하기 위해 관여하는 효소이다. CB-5083은 p97 활성을 결합하고 억제해서 유비퀴틴화된 단백질의 축적을 일으키고 단백질 독성 스트레스를 유도하고 사멸을 활성화해서 항종양 활성을 발휘한다 (그림 1)[2]. CB-5083은 다발성 골수종과 고형종양 모델에 대한 항암제로 일반적으로사용된다[3,4].

그림 1. CB-5083의 작용 기전[5,6]. CB-5083은 발로신 함유 단백질(VCP) p97을 특이적으로 표적화한다. p97의 ATPase 활성을 억제해서 CB-5083은 유비퀴틴-프로테아좀 시스템과 내질망 관련 단백질 분해(ERAD)를 차단해서 오접힌 단백질과 손상된 단백질의 축적을 일으킨다. 그 다음에 단백질의 펼침 반응과 단백질 독성 스트레스를 유발해서 최종적으로 암세포 사멸로 이어진다.

체외 실험에서 CB-5083 (0.3125-20μM)으로 8시간 동안 다발성 골수종 RPMI8226 세포를 처리하면 단백질의 펼침 반응(UPR) 마커 sXBP1과 BiP의 발현을 유도하고 K48 다중 유비퀴틴화 단백질의 축적을 일으킨다[5]. 인간 골육종 SJSA-1과 U2OS 세포를 CB-5083 (0.5, 1 μM)으로 48시간 동안 처리하면 세포주기 G1기 지연을 유도하고 사멸을 촉진한다[7]. THP-1과 MV4-11 세포를 CB-5083 (200nM)으로 6시간 동안 처리하면 발로신 함유 단백질(VCP) 자체의 유비퀴틴화 수준, 프로테아좀 성분, 자가포식 관련 단백질 그리고 DNA 손상 반응 인자의 유비퀴틴화 수준을 포함해서 유비퀴틴 변형된 프로테옴이 변화한다[8].

체내 실험에서 CB-5083 (60mg/kg)을 중증 복합면역결핍증(SCID) 베이지 쥐에 경구 투여하면 RPMI8226 이종이식 모델에서 CB-5083의 혈장 농도는 24시간 동안 2-20μM 범위를 유지하고 지속적으로 유의한 K48 다중 유비퀴틴화 단백질 축적, UPR 활성화 그리고 기준치 대비 CHOP 단백질 발현이 2.7배 증가하였다[5]. 2개월령 VCPR155H/R155H 순합자 쥐에 5개월 동안 CB-5083 (15mg/kg)을 경구 투여하면 쥐는 잘 견디고 체중은 꾸준히 증가하고 기관 무게는 정상이고 간 효소(예: 아스파르테이트 아미노트랜스퍼라제(AST)와 알라닌 아미노트랜스퍼라제(ALT))는 증가하지 않고AST 수준은 현저하게 감소하였다[9].
