Data Sheet SDS 产品使用指南

2-Thiouridine (sU) is a modified nucleobase found in tRNAs that is known to stabilize U:A pairs and modestly destabilize U:G wobble pairs. Modified nucleobases, including 2-thiouridine, are used to study nucleic acid structure and function as well as to engineer novel RNA-based biomolecules.

生物活性

2-Thiouridine is an orally active modified nucleobase. 2-Thiouridine stabilizes U:A base pairs and destabilizes U:G wobble base pairs. 2-Thiouridine significantly improves the efficiency and accuracy of nonenzymatic replication of mixed-sequence A/U-containing RNA templates. 2-Thiouridine exhibits antiviral activity against multiple positive-sense single-stranded RNA viruses (DENV2, ZIKV, YFV, JEV, WNV, CHIKV, human coronaviruses ( [HCoV]-229E, HCoV-OC43, SARS-CoV), and MERS-CoV).

体外研究

2-Thiouridine (0.625-40 μM) inhibits the replication of ssRNA+ viruses (DENV2, ZIKV, YFV, JEV, WNV, CHIKV, human coronaviruses [HCoV-229E, HCoV-OC43, SARS-CoV], and MERS-CoV) in a dose-dependent manner.

体内研究

2-Thiouridine (50-150 mg/kg; oral; twice daily) prolonged survival rates and reduced viral RNA loads in serum, spleen, and other tissues in DENV2-infected mice.
2-Thiouridine (2-300 mg/kg; intravenous injection (2-20 mg/kg; once daily) or oral administration (300 mg/kg; twice daily); for 5 days) improved survival rates, reduced pulmonary viral titers, and lowered inflammatory factor levels in a SARS-CoV-2-infected mouse model.

1.

请依序添加每种溶剂：10% DMSO → 40% PEG300 → 5% Tween-80 → 45% saline

Solubility: ≥ 2.5 mg/mL (9.61 mM); Clear solution

此方案可获得 ≥ 2.5 mg/mL (9.61 mM，饱和度未知) 的澄清溶液。

以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。
2.

请依序添加每种溶剂：10% DMSO → 90% (20% SBE-β-CD in saline)

Solubility: ≥ 2.5 mg/mL (9.61 mM); Clear solution

此方案可获得 ≥ 2.5 mg/mL (9.61 mM，饱和度未知) 的澄清溶液。

以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD ⽣理盐⽔⽔溶液中，混合均匀。
