Enniatin A is a Fusarium mycotoxin. Enniatin A inhibits acyl-CoA: cholesterolacyltransferase (ACAT) activity with an IC50 of 22 μM in an enzyme assay using rat liver microsomes.
Enniatins B decreases the activation of ERK (p44 p42). Enniatin B is a Fusarium mycotoxin. Enniatin B inhibits acyl-CoA: cholesterolacyltransferase (ACAT) activity with an IC50 of 113 μM in an enzyme assay using rat liver microsomes.
Enniatin B1 crosss the blood-brain barrier. Enniatin B1 decreases the activation of ERK (p44 p42). Enniatin B1 inhibits moderately TNF-α-induced NF-κB activation.Enniatin B1 is a Fusarium mycotoxin. Enniatin B1 inhibits acyl-CoA: cholesterolacyltransferase (ACAT) activity with an IC50 of 73 μM in an enzyme assay using rat liver microsomes.
AcylCoA:cholesterolacyltransferase (ACAT) is an intracellular cholesteryl ester synthase tied closely to the absorption of dietary cholesterol. Oleic acid-2,6-diisopropylanilide is an inhibitor of acylCoA:cholesterolacyltransferase with an IC50 of 7 nM. When co-administered to rabbits or rats fed a high fat, high cholesterol diet, oleic acid-2,6-diisopropylanilide decreased low density lipoproteins and elevated high density lipoprotein levels when administered at 0.05%.
Acyl-coenzyme A: cholesterolacyltransferase-1 and -2 (ACAT-1 and ACAT-2) catalyze the formation of cholesterol esters from cholesterol and long chain fatty acyl-coenzyme A, and may play a role in the development of atherosclerosis. CAY10485 inhibits human ACAT-1 and ACAT-2 with an IC50 values of 95 and 81 μM, respectively. It also inhibits copper-mediated oxidation of low density lipoproteins by 91% at a concentration of 2 μM.
Beauveriolide I is a cyclodepsipeptide that has been found inBeauveriaand an inhibitor of lipid droplet formation.1It inhibits lipid droplet formation when used at concentrations of 3 and 10 μM, as well as inhibits cholesterol synthesis (IC50= 0.78 μM), in primary mouse peritoneal macrophages.1,2Beauveriolide I also inhibits acyl-coenzyme A:cholesterolacyltransferase (ACAT) activity in mouse macrophage membranes (IC50= 6 μM).2 1.Namatame, I., Tomoda, H., Si, S., et al.Beauveriolides, specific inhibitors of lipid droplet formation in mouse macrophages, produced by Beauveria sp.

Beauveriolide III is a cyclodepsipeptide that has been found inBeauveriaand an inhibitor of lipid droplet formation.1It inhibits lipid droplet formation when used at concentrations of 3 and 10 μM, as well as inhibits cholesterol synthesis (IC50= 0.41 μM), in primary mouse peritoneal macrophages.1,2Beauveriolide III also inhibits acyl-coenzyme A:cholesterolacyltransferase (ACAT) activity in mouse macrophage membranes (IC50= 5.5 μM).2Beauveriolide III (25 and 50 mg kg) reduces the size of aortic atherosclerotic lesions inLdlr- -andApoE- -mouse models of atherosclerosis. 1.Namatame, I., Tomoda, H., Si, S., et al.Beauveriolides, specific inhibitors of lipid droplet formation in mouse macrophages, produced by Beauveria sp.
