- 产品描述:
Domatinostat (4SC-202)是一种选择性的I类HDAC抑制剂,对HDAC1,HDAC2,和HDAC3的IC50分别为1.20 μM,1.12 μM,和0.57 μM。也对Lysine specific demethylase 1 (LSD1)表现出抑制活性。Phase 1
- 靶点: HDAC3(Cell-free assay):0.57 μM; HDAC2(Cell-free assay):1.12 μM; HDAC1(Cell-free assay):1.20 μM; HDAC11(Cell-free assay):9.7 μM; HDAC5(Cell-free assay):11.3 μM; HDAC10(Cell-free assay):21 μM; HDAC9(Cell-free assay):50 μM;Apoptosis; HDAC
- 体外研究:
在HeLa细胞中,4SC-202诱导组蛋白H3高度乙酰化,EC50 为1.1 μM。4SC-202通过干扰有丝分裂纺锤体的正常发育诱导G2/M细胞周期阻滞,并引起纺锤体塌陷和多个成核中心。此外,4SC-202对人癌症细胞系表现出广谱抗肿瘤活性,IC50 为0.7 μM
- 体内研究:
在体内,4SC-202具有较高的口服生物利用度,并表现出高代谢稳定性和低血浆清除率。在A549 NSCLC 异种移植和RKO27结肠癌模型中,4SC-202 (120 mg/kg p.o.)表现出显著的强抗肿瘤活性
- 细胞实验: Cell lines: NCI-H460,A549,MCF7,MDA-MB-468,SK-BR-3,SK-OV-3,A2780,RKO (p21),HCT-15,PC-3,HeLa,Cal 27,A-431,Hec-1-A,K-562,EOL1,和 CCRF-CEM 细胞 Concentrations: ~10 μM Incubation Time: 72小时 Method: CRC cell lines (HT-29, HCT-116, HCT-15, and DLD1), the primary human colon cancer cells, or primary human colon epithelial cells were treated with applied concentrations of 4SC-202, cells were further cultured for indicated time, and cell survival was tested by MTT assay or trypan blue staining assay; cell proliferation was tested by clonogenicity assay. Expression of listed proteins was tested by Western blots.
- 动物实验: Animal Models: A549 NSCLC 移植瘤模型和 RKO27 结肠癌模型 Dosages: 120 mg/kg Administration: p.o.
