Descripciòn

Lipoxamycin hemisulfate is an antifungal antibiotic and a potent serine palmitoyltransferase inhibitor with an IC₅₀ of 21 nM^[1]^[2].

IC₅₀ & Target

Serine palmitoyltransferase^[1]

In Vitro

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^[1].
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^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

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^[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 4 mg/mL (9.49 mM); Clear solution

This protocol yields a clear solution of ≥ 4 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
