Lipoxamycin hemisulfate

产品介绍

Lipoxamycin hemisulfate 是一种抗真菌抗生素，也是一种有效的丝氨酸棕榈酰转移酶 (serine palmitoyltransferase) 抑制剂，IC₅₀ 为 21 nM。

生物活性

Lipoxamycin hemisulfate is an antifungal antibiotic and a potent serine palmitoyltransferase inhibitor with an IC₅₀ of 21 nM.

体外研究

Lipoxamycin has antifungal activity against a panel of humanpathogenic fungi with better potency against some of the Candida species (MIC values, 0.25-16 µg/mL). Cryptococcus neoformans is the most sensitive organism, followed by various species of Candida. Other filamentous fungi are sensitive to the Lipoxamycin in disk diffusion assays.
Lipoxamycin has a long alkyl chain and an amino-containing polar head group. Lipoxamycin is on the same order of potency as the sphingofungins and also have potent activity against the mammalianenzyme.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

Lipoxamycin is highly toxic in mice when applied subeutaneously or topically. Toxicity may be mechanism based, since studies with a Chinese hamster ovary cell mutant have shown that the serine palmitoyltransferase is an essential enzymein mammalian cells.

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 (sealed storage, away from moisture)。-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
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

1.

请依序添加每种溶剂： 10% DMSO 90% (20% SBE-β-CD in saline)
Solubility: ≥ 4 mg/mL (9.49 mM); Clear solution

此方案可获得 ≥ 4 mg/mL (9.49 mM，饱和度未知) 的澄清溶液。
以 1 mL 工作液为例，取 100 μL 40.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中，混合均匀。
将 2 g 磺丁基醚 β-环糊精加入 5 mL 生理盐水中，再用生理盐水定容至 10 mL，完全溶解，澄清透明
