生物活性

GS143 is a selec­tive IκBα ubiquitination inhibitor with an IC50 of 5.2 μM for SCF-mediated IκBα ubiquitylation. GS143 sup­presses NF-κB acti­va­tion and tran­scrip­tion of tar­get genes and does not inhibit proteasome activity. GS143 has anti-asthma effect.

体外研究

GS143 (10 μM or 20 μM) inhibits antigen-induced differentiation of Th2 cells but not of Th1 cells in vitro. The IL-4 pro­duc­tion in Th2-polar­iz­ing con­di­tion is mark­edly sup­pressed by GS143 in a dose-depen­dent man­ner.
GS143 suppresses the transcription of TNFα-induced NF-κB with a mean IC50 value of 10.5 μM. GS143 also inhibits TNFα-induced expression of ICAM-1 in HT-29 colon cancer cells with an IC50 value of 6.1 μM. The production levels of TNFα and IL-1β in LPS-activated THP-1 cells are inhibited with IC50 values of 5.3 μM and 2.1 μM, respectively. GS143 does not inhibit p53 and β-catenin.

体内研究

GS143 (16-32 μg/body; intranasal administration; once; BALB/c mice) treatment suppresses antigen-induced NF-κB activation in the lung of sensitized mice. GS143 treatment also inhibits antigen-induced eosinophil and lymphocyte recruitment into the airways and the expression of Th2 cytokines and eotaxin in the airways.

Animal Model: BALB/c mice (age 7-8weeks) injected with oval­bu­min
Dosage: 16 μg/body or 32 μg/body
Administration: Intranasal administration; once
Result: Suppressed antigen-induced NF-κB activation in the lung of sensitized mice.

请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。
储备液的保存方式和期限:-80°C, 6 months; -20°C, 1 month。-80°C 储存时,请在 6 个月内使用,-20°C 储存时,请在 1 个月内使用。

In Vivo:

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

    请依序添加每种溶剂: 10% DMSO    90% corn oil

    Solubility: 2.08 mg/mL (4.46 mM); Clear solution; Need ultrasonic

    此方案可获得 2.08 mg/mL (4.46 mM) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
