包装规格:100mg in glass bottle
产品简介:能抗真菌和细菌,可通过阻断质子泵扰乱膜运输。 Zinc Pyrithione zinc is a dimer of two pyrithione molecules bound by zinc. It is commonly found as an ingredient of commercial anti-dandruff shampoos. This products acts as an antifungal and antibacterial.
溶解性:溶于DMSO(33.33 mg/mL 超声)
储备液保存:-80°C, 6 months; -20°C, 1 month。
体内实验:1、请依序添加每种溶剂: 10% DMSO→90% Corn Oil Solubility: ≥ 2.5 mg/mL (7.87 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,此方案实验周期在半个月以上的动物实验酌情使用。 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。 注:建议您现用现配,当天使用。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 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。
靶点:Proton pump
体外研究:Zinc pyrithione is considered as a coordination complex of zinc. The pyrithione ligands, which are formally monoanions, are chelated to Zn 2+ via oxygen and sulfur centers. In the crystalline state, zinc pyrithione exists as a centrosymmetric dimer, where each zinc is bonded to two sulfur and three oxygen centers. In solution, however, the dimers dissociate via scission of one Zn-O bond. Zinc pyrithione, which is a dimer but is probably biologically active as a monomer, induces plasma membrane depolarization with half-maximal effect (K1/2) of about 0.3 mM. Zinc Pyrithione (10 nM-10 μM; 72 hours) significantly induces cell death in AAVS1 cells.
保存条件:-20°C
