人乳中含有脂肪酸棕榈油酸[1]。尽管摄入 1% 氯化钠水会增加氯化钠消耗量,但含有 1% 棕榈油酸的膳食显着提高了 SHRSP 的存活率,同时降低了给予各种脂肪酸的 SHRSP 中风的发病率 [2]。

- 对易卒中型自发性高血压大鼠(SHRSP)中风预防的作用:膳食补充(Z)-十六碳-9-烯酸[(Z)-Hexadec-9-enoic acid]可降低SHRSP的中风发生率并延长存活时间。喂食含1.5%(Z)-十六碳-9-烯酸[(Z)-Hexadec-9-enoic acid]饲料的大鼠,在12周时中风发生率为30%,而对照组(不含该脂肪酸的标准饲料)为85%。补充(Z)-十六碳-9-烯酸[(Z)-Hexadec-9-enoic acid]组的中位存活时间为14周,比对照组长5周。此外,与对照组相比,该脂肪酸可轻微降低SHRSP的收缩压(补充8周时降低约15 mmHg),但无法将血压降至正常血压大鼠水平 [2]

| 动物实验 |
- Stroke prevention experiment in SHRSP: Male SHRSP (6 weeks old) were randomly divided into 2 groups (n=20 per group): control group and (Z)-Hexadec-9-enoic acid-supplemented group. The control group was fed a standard rodent diet, while the supplemented group was fed the same standard diet mixed with (Z)-Hexadec-9-enoic acid at a final concentration of 1.5% (w/w). All rats had free access to food and water throughout the experiment. The experiment lasted for 16 weeks, with weekly measurements of systolic blood pressure using a tail-cuff method. Rats were observed daily for clinical signs of stroke (e.g., paralysis, convulsions, lethargy), and stroke incidence and survival time were recorded. At the end of the experiment, surviving rats were sacrificed, and no histopathological analysis of major organs was reported [2]

| 其他信息 |
Palmitoleic acid is a hexadec-9-enoic acid in which the double bond at position C-9 has cis configuration. It has a role as an EC 3.1.1.1 (carboxylesterase) inhibitor, a Daphnia galeata metabolite, a human blood serum metabolite, an algal metabolite and an Escherichia coli metabolite. It is a conjugate acid of a palmitoleate.
Palmitoleic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Palmitoleic acid has been reported in Agaricus blazei, Phormidium tenue, and other organisms with data available. palmitoleic acid is a metabolite found in or produced by Saccharomyces cerevisiae. See also: Cod Liver Oil (part of); Krill oil (part of); Saw Palmetto (part of). - (Z)-Hexadec-9-enoic acid (palmitoleic acid) is a monounsaturated fatty acid present in human breast milk. In breast milk from Nigerian women, its content was 2.8±0.3% of total fatty acids, while in breast milk from Japanese women, it was 1.9±0.2% of total fatty acids; the difference was statistically significant [1] - (Z)-Hexadec-9-enoic acid exerts its stroke-preventive effect in SHRSP possibly by improving vascular integrity and reducing vascular inflammation, though the exact molecular mechanism was not fully elucidated in the study [2] |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
