| 体外研究 (In Vitro) |
在人和大鼠 PBMC 以及人和大鼠全血中,AZD2906 是一种选择性糖皮质激素受体 (GR),IC50 值分别为 2.2、0.3、41.6 和 7.5 nM [1]。
AZD2906 在按照现行ICH和OECD指南进行的细菌突变(Ames)试验中结果为阴性。 AZD2906 在按照现行ICH和OECD指南进行的小鼠淋巴瘤Tk基因突变试验中未显示活性(阴性结果)。 AZD2906 在使用小鼠淋巴瘤细胞进行的体外微核试验中未显示活性(阴性结果)。 在大鼠体内的代谢物谱分析未显示细菌致突变性的结构警示。 基于大鼠全身定量放射自显影研究,该化合物及其代谢物未显示形成反应性代谢物的证据。 |
| 体内研究 (In Vivo) |
治疗两天后,AZD2906(5、25、50 mg/kg,口服)可以增加大鼠骨髓中微核未成熟红细胞(MIE)的数量[1]。 AZD2906(5、25 mg/kg,口服)会导致大鼠胸腺中度至重度皮质淋巴细胞萎缩,并导致大鼠肝脏中糖原积聚[1]。
给予雄性Wistar Han大鼠AZD2906(两次口服给药,间隔24小时),在5、25和50 mg/kg剂量下,与溶媒对照组相比,骨髓中微核化未成熟红细胞(MIE)的频率显著增加。 当每只动物计数6000个未成熟红细胞时,增加具有统计学显著性(p < 0.001),是对照组值的3倍以上。 在所有剂量水平均观察到MIE频率增加,但没有明显的剂量反应关系,可能是因为血药浓度远远超过其GR的IC50。 AZD2906 引起血液学参数变化:绝对网织红细胞数量显著减少(约44-55%),白细胞总数减少(约75%),淋巴细胞减少(约95-97%),单核细胞减少(约75%),嗜酸性粒细胞减少(85-100%),同时中性粒细胞数量轻微增加(65-73%)。 在骨髓中,流式细胞术显示有核细胞总数减少(6-16%),淋巴样细胞减少(约58-59%)。 组织病理学检查显示肝脏糖原积聚,胸腺皮质淋巴细胞中度至显著萎缩,以及骨髓普遍轻度萎缩,同时骨髓中髓系与红系细胞比例发生改变,有利于红系细胞富集或滞留。 使用相同剂量(可增加骨髓微核频率)进行的大鼠肝脏彗星试验显示阴性结果,表明在肝脏中未引起直接DNA损伤。 |

Animal/Disease Models: Male Wistar Han rat (10 weeks old) [1]
Doses: 5, 25, 50 mg/kg Route of Administration: Orally for 2 days Experimental Results: All doses caused micronucleated immature erythrocytes (MIE) after analysis With the addition of standard 2000 IE. For the bone marrow micronucleus test: Groups of seven male Wistar Han rats were given two oral doses of AZD2906 (suspended in 0.5% w/v hydroxypropyl methylcellulose and 0.1% Tween 80 in 50 mM citrate buffer, pH 4.0) at 5, 25, or 50 mg/kg, 24 hours apart. Animals were killed 24 hours after the second dose. Bone marrow was collected from a femur, and smears were prepared, stained with acridine orange, and scored for micronucleated immature erythrocytes. For haematology and histopathology investigation: Groups of eight male rats were given two oral doses of vehicle, 5, or 25 mg/kg AZD2906 and killed 24 hours after the second dose. Blood was collected for haematology analysis. One femur was taken for flow cytometric analysis of bone marrow cell populations. The other femur (attached to tibia), liver, and thymus were collected, fixed, decalcified (for bone), processed, and embedded for histopathological examination by light microscopy. |
| 药代性质 (ADME/PK) |
In rats, following two oral doses, AZD2906 at 5 mg/kg achieved a Cmax of 643 nmol/L and an AUC of 7270 nmol·h/L.
At 25 mg/kg, it achieved a Cmax of 2520 nmol/L and an AUC of 36400 nmol·h/L. The compound is highly protein-bound in both rat and human blood. A quantitative whole-body autoradiography study in rats showed no evidence of tissue retention of radioactivity (except in choroid and retinal pigment), indicating a lack of reactive metabolite formation and widespread distribution/elimination. |
| 毒性/毒理 (Toxicokinetics/TK) |
The maximum tolerated dose (MTD) in rats for two oral doses was 50 mg/kg.
At doses of 5 and 25 mg/kg, AZD2906 induced glycogen accumulation in the liver and moderate to marked cortical lymphocytic atrophy in the thymus, which are expected pharmacological effects of GR agonism. No macroscopic evidence of damage to the gastrointestinal tract was observed at the tested doses. The study did not establish a No Observed Effect Level (NOEL) for the increase in bone marrow micronucleus frequency, as increases were seen at all tested doses. |

| 其他信息 |
AZD2906 is a novel selective glucocorticoid receptor agonist discovered jointly by AstraZeneca and Bayer HealthCare Pharmaceuticals.
The increased micronucleus frequency in rat bone marrow observed with AZD2906 is concluded to be a consequence of its pharmacological (GR agonist) effects and not indicative of genotoxic or carcinogenic potential. This conclusion is supported by: negative standard in vitro genotoxicity assays, negative in vivo comet assay, similar effects seen with reference GR agonist prednisolone, and the long-term clinical safety record of GR agonists like prednisolone. The proposed mechanism for increased MIE may involve GR-mediated stimulation of erythropoiesis (either direct or secondary to myelosuppression) or other unknown effects on bone marrow cell function, leading to an increased rate of erythroid cell division and potential micronucleus formation during accelerated erythropoiesis. |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
