Mocetinostat (MGCD0103)는 9가지 인간 재조합 HDAC 중 HDAC1, HDAC2, HDAC3, HDAC11을 포함한 일부만 나노몰 또는 낮은 마이크로몰 농도에서 용량 의존적으로 억제합니다. 시험관 내에서 인간 HDAC1 및 HDAC2 효소에 대해 가장 강력한 억제 활성을 나타내며, 클래스 II HDAC는 억제하지 않습니다. 이 화합물의 외부 고리 아미노기는 효소 억제 활성에 필요합니다. 왜냐하면 데스아미노 유사체와 함께 HDAC1 및 HDAC2에 대한 HDAC 억제 활성이 완전히 사라지기 때문입니다. 억제 활성은 6 μM에서 최대 평형에 도달하며, MGCD0103에 의해 영향을 받는 최대 억제 가능 효소 풀은 HCT116 세포에서 전체 효소 활성의 75%이며, NVP-LAQ824는 이들 세포에서 거의 100%를 억제합니다. A549 세포에서도 전체 세포에서 HDAC 활성의 용량 의존적 억제를 나타냅니다.

키나아제 분석
시험관 내 HDAC 효소 분석
탈아세틸화 효소 분석은 동질 형광 방출 분석을 기반으로 합니다. 정제된 재조합 HDAC 효소는 다양한 농도로 희석된 Mocetinostat (MGCD0103)와 함께 분석 완충액 [25 mM HEPES (pH 8.0), 137 mM NaCl, 1 mM MgCl2, 2.7 mM KCl]에서 실온에서 10분 동안 배양됩니다. 기질 Boc-Lys(ε-Ac)-AMC를 반응에 첨가하여 37 °C에서 추가로 배양합니다. 기질의 농도와 배양 시간은 HDAC 효소의 다른 아이소타입에 따라 다릅니다. 실온에서 20분간 트립신 배양하면 탈아세틸화된 기질로부터 형광 물질이 방출됩니다. 형광 신호는 360 nm 여기, 470 nm 방출 및 435 nm 컷오프에서 형광계로 감지됩니다.
생체 내(In vivo)

Mocetinostat (MGCD0103)는 누드 마우스에서 인간 종양 이종이식편의 성장을 유의하게 억제했으며, 항종양 활성은 종양 내 히스톤 아세틸화 유도와 상관관계가 있었습니다. 이 화합물(2HBr 염)의 P.O. 투여는 매일 13일 투여 후 누드 마우스에서 이식된 진행성 A549 종양의 성장을 용량 의존적으로 유의하게 감소시켰습니다. 이는 (2HBr 염 170 mg/kg, 자유 염기 120 mg/kg에 해당) 체중 변화 없이 차량 단독 치료와 비교하여 종양 성장을 유의하게 차단했습니다. 또한, 백혈구 수를 감소시키지 않으며 잘 tolerated됩니다. 이 화합물은 NSCLC H1437을 포함한 다른 많은 인간 종양 이종이식 모델에서도 경구 활성을 가집니다. 80 mg/kg (자유 염기)에서, 매일 13일 p.o. 투여 후 동물 체중 감소 없이 H1437 종양의 성장을 거의 완전히 차단합니다. 이는 폐동맥압을 더욱 극적으로 감소시킵니다. 더욱이, 이 화합물은 폐동맥 가속 시간을 개선하고 폐동맥 흐름 엔벨로프의 수축기 노칭을 감소시켜, HDAC 억제제가 폐혈관 리모델링 및 경직에 긍정적인 영향을 미친다는 것을 시사합니다.
