产品描述 | Cyclo(Tyr-Val) is a natural product for research related to life sciences. The catalog number is TN6690 and the CAS number is 21754-25-6. |
体外活性 | In order to provide more natural antifouling compounds, marine bacterium Pseudomonas putida isolated from the sponge Haliclona sp. was explored to test its anti-diatom compounds. METHODS AND RESULTS: The strain was identified by colonial morphology, scanning electron microscope (SEM) and 16S rDNA sequence analysis. The separation procedure was guided by bioactive (Anti-diatom) and chemical (TLC, DAD-HPLCand 1H NMR) analysis, and their structures were elucidated by spectrographic techniques. The anti-diatom activity of all purified compounds was assayed. Strain 272 isolated from the sponge Haliclona sp. was identified as Pseudomonas putida. Six diketopiperazine compounds were isolated from the culture of this strain and their structures were determined as cyclo(Leu-Pro) (1), cyclo (Leu-Ala) (2), cyclo(Phe-Ala) (3), Cyclo(Tyr-Val) (4), cyclo(Ala-Tyr) (5), cyclo(Ala-Trp) (6); Compounds 3 and 6 displayed significant anti-diatom activity with the inhibitory rate of 50% and 85% at the concentration of 50 microg/mL, respectively. CONCLUSIONS: The anti-diatom compounds isolated from marine bacterium Pseudomonas putida were cyclo (Phe-Ala) and cyclo (Ala-Trp). |

对于不同动物的给药剂量换算,您也可以参考 更多...
请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
