Fimepinostat (CUDC-907)은 PI3Kβ, PI3Kγ, PI3Kδ, PI3KɑH1047R 및 PI3KɑE545K와 같은 다른 PI3K 동형을 각각 54 nM, 311 nM, 39 nM, 73 nM 및 62 nM의 IC50으로 억제합니다. 또한 HDAC8, HDAC6 및 HDAC11과 같은 HDAC 아형도 각각 191 nM, 27 nM 및 5.4 nM의 IC50으로 억제합니다.

또한 이 화합물은 낮은 효능으로 다른 유형의 HDAC 효소 활성을 억제합니다. Granta 519, DOHH2, RL, Pfeiffer, SuDHL4, Daudi 및 Raji와 같은 일련의 B세포 림프종의 성장을 각각 7 nM, 1 nM, 2 nM, 4 nM, 3 nM, 15 nM 및 9 nM의 IC50으로 억제합니다. 또한 RPMI8226, OPM-2 및 ARH77을 포함한 골수종의 증식을 각각 2 nM, 1 nM 및 5 nM의 IC50으로 차단합니다. Fimepinostat은 다발성 골수종 및 B세포 림프종에서 더 큰 항종양 활성을 나타냅니다.

생체 내(In vivo)

Fimepinostat (CUDC-907)은 생쥐 종양에서 긴 반감기를 가지며, 이종 이식 종양에서 암세포 증식을 억제하는 동시에 apoptosis를 유도합니다.

NHL 및 MM 모델의 효능 연구에서 이 화합물은 단일제 PI3K 또는 HDAC 억제제 참조 화합물 또는 최대 내성 용량(MTD)으로 투여된 두 가지 약물의 조합보다 더 효과적입니다. 또한 MTD 용량으로 투여될 때 PI3Kδ-선택적 억제제 CAL-101보다 더 효과적입니다.

자주 묻는 질문

질문 1:
How to solve it for in vivo studies (p.o.)?

답변:
If you decide to take P.O. as your administration route, we suggest using 1% CMC-Na to dilute it as a suspension solution for gavage.

질문 2:
What is its half-life in vivo?

답변:
It is said to have a long half-life in mouse tumor model: http://cancerres.aacrjournals.org/content/72/8_Supplement/3744.short, however, its not formally published and we have no detail of how long it is.
