生物活性:
Lipoxamycin is an antifungal antibiotic and a potent serine palmitoyltransferase inhibitor with an IC50 of 21 nM.

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.

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.
