生物活性

SIBA (5'-Isobutylthioadenosine) is a transmethylation inhibitor (SAH (HY-19528) analogue), with potent anti-proliferative activity. SIBA reversibly inhibits the production of HSV-1 by blocking methylation, specifically by blocking the 5' end-capping of viral mRNA. SIBA also inhibits the growth of tumour cells in vitro and metastatic spread in vivo. SIBA can be used in cancer, HSV-1 infection and anti-malaria studies[1][2][3].

IC50 & Target[2]

Plasmodium

 

HSV-1

 

体外研究
(In Vitro)

SIBA (0.5 mM; 24-96 h) shows strong anti-proliferative activity against 3LL and RMS-J1 tumour cells[1].
SIBA (1 mM; 12, 24 h) reversibly inhibits HSV production in HEp2 cells (infected by HSV-1)[2].
SIBA inhibits protein synthesis by 98% after 10 h infection of HEp2 cells (infected by HSV-1)[2].
SIBA (1 mM; 8.5 h) inhibits protein synthesis and RNA methylation in HEp2 cells (infected by HSV-1)[2].
SIBA (0.5, 1.0 mM; 24, 48 h) inhibits the conversion of putrescine into spermidine and/or spermine and that this inhibition is a reversible one (interferes with polyamine biosynthesis, probably by blocking aminopropyltransferase)[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

动物实验:

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

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

    Solubility: ≥ 2.5 mg/mL (7.37 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    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;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
