Desidustat is a N-acyl-amino acid.
Desidustat is under investigation in clinical trial NCT04012957 (Desidustat in the Treatment of Anemia in CKD).
Desidustat is an orally bioavailable, hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor (HIF-PHI), with potential anti-anemic and anti-inflammatory activities. Upon administration, desidustat binds to and inhibits HIF-PH, an enzyme responsible for the degradation of transcription factors in the HIF family under normal oxygen conditions. This prevents HIF breakdown and promotes HIF activity. Increased HIF activity leads to an increase in endogenous erythropoietin production, thereby enhancing erythropoiesis. It also reduces the expression of the peptide hormone hepcidin, improves iron availability, and boosts hemoglobin (Hb) levels. HIF regulates the expression of genes in response to reduced oxygen levels, including genes required for erythropoiesis and iron metabolism. In addition, HIF 1-alpha (HIF1A) may play a role in reducing inflammation during acute lung injury (ALI) through HIF-dependent control of glucose metabolism in the alveolar epithelium.

Mechanism of Action
The small molecule hypoxia-inducible factor, desidustat, inhibits the prolyl hydrozylase and stimulates erythropoiesis. It is currently being investigated against anemia of inflammation and COVID-19.

DMSO : ~10 mg/mL (~30.09 mM)

配方 1 中的溶解度: ≥ 1 mg/mL (3.01 mM) (饱和度未知) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (这些助溶剂从左到右依次添加，逐一添加), 澄清溶液。
例如，若需制备1 mL的工作液，可将100 μL 10.0 mg/mL澄清DMSO储备液加入400 μL PEG300中，混匀；然后向上述溶液中加入50 μL Tween-80，混匀；加入450 μL生理盐水定容至1 mL。
*生理盐水的制备：将 0.9 g 氯化钠溶解在 100 mL ddH₂O中，得到澄清溶液。

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果，工作液请现配现用！
6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们;
7、 以上所有助溶剂都可在 Invivochem.cn网站购买。
