生物活性

Walrycin B is a novel antibacterial compound specifically targeting the essential WalR response regulator. IC50 value: 0.39 ug/ml (MIC for B. subtilis 168); 3.13 ug/ml (MIC for S. aureus N315) [1] Target: bacterial WalR response regulator; Antibacterial Walrycin B is known as an analog of toxoflavin (a phytotoxin from Burkholderia glumae), which has been shown to have a strong MIC for B. subtilis and S. aureus but whose mode of action is not clear. The compound could also interact with WalR to cause bactericidal effects. Walrycins are a new class of potent small molecule compounds that kill bacterial cells by targeting the RR WalR and inhibiting this essential signal transduction pathway. They not only have therapeutic potential but will also prove to be useful reagents for the further study of the WalK/WalR TCS. Walrycin B target WalR and lead to cell death in both B. subtilis and S. aureus.

  • 1.

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

    Solubility: 2.5 mg/mL (7.41 mM); Suspended solution; Need ultrasonic

    此方案可获得 2.5 mg/mL (7.41 mM) 的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    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% corn oil

    Solubility: 2.5 mg/mL (7.41 mM); Clear solution; Need ultrasonic

    此方案可获得 2.5 mg/mL (7.41 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 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。
