A-366 是一种高效、高选择性的肽竞争性组蛋白甲基转移酶G9a抑制剂,对 G9a 和 GLP 的IC50分别为 3.3 和 38 nM。A-366 比其他 21 种甲基转移酶具有 1000 倍以上的选择性。A-366 是一种有效的Spindlin1-H3K4me3相互作用的抑制剂 (IC50=182.6 nM)。A-366 对人 H3R (Ki=17 nM) 表现出很高的亲和力,并且在组胺能和多巴胺能受体家族的亚群间表现出亚型选择性。
生物活性 | A-366 is a potent, highly selective, peptide-competitivehistone methyltransferaseG9ainhibitor withIC50s of 3.3 and 38 nM for G9a and GLP (EHMT1), respectively. A-366 shows >1000-fold selectivity over 21 other methyltransferases. A-366 is also a potent, nanomolar inhibitor of theSpindlin1-H3K4me3-interaction(IC50=182.6 nM). A-366 displays high affinity at human histamine H3 receptor (Ki=17 nM) and shows subtype selectivity among subsets of the histaminergic and dopaminergic receptor families[1][2][3][4]. |
体外研究 (In Vitro) | A-366 (0.01-10 μM; 14 days) induces differentiation and affects viability in MV4;11 cells[4]. A-366 (0.3-3 μM; 72 hours) reduces the total levels of H3K9me2 in a time and concentration dependent manner with a cellular EC50 of ~300 nM in PC-3 prostate adenocarcinoma cells. A-366 (0.01-10 μM; 4 days; HL-60 cells) results in a dose-dependent differentiation and a corresponding decrease in proliferation. DNA content analysis of A-366-treated HL-60 cells showed an accumulation of cells in G1 consistent with cytostasis[4].
Cell Viability Assay[4] Cell Line: | MV4;11 cells | Concentration: | 0.01-10 μM | Incubation Time: | 14 days | Result: | Resulted in inhibited proliferation and a decrease in viability corresponding to the dose response observed for CD11b staining. |

体内研究 (In Vivo) | A-366 (30 mg/kg; osmotic mini-pump; daily for 14 days) treatment of MV4;11 xenografts elicits growth inhibition[4].
Animal Model: | 6-8 week old SCID-beige female mice (MV4;11 xenografts)[4] | Dosage: | 30 mg/kg | Administration: | By osmotic mini-pump; daily for 14 days | Result: | A modest 45% tumor growth inhibition resulting from A-366 treatment in this model. |
