Description

Undecanoic acid (UDA) is a fatty acid with significant antimycotic activity. Undecanoic acid is a straight-chain, eleven-carbon saturated medium-chain fatty acid found in body fluids; the most fungitoxic of the C7:0 - C18:0 fatty acid series. It has a role as a human metabolite and an antifungal agent. It is a straight-chain saturated fatty acid and a medium-chain fatty acid. It is a conjugate acid of an undecanoate. It derives from a hydride of an undecane. Undecanoic acid inhibited the production of exocellular lipase and keratinase but stimulated the production of exocellular phospholipase A in T. rubrum undecanoic acid-resistant mutant (udar). At its minimum inhibitory concentration, undecanoic acid inhibits biosynthesis of phosphatidyl serine, phosphatidyl ethanolamine and polyphosphoinositol but does not inhibit the synthesis of phosphatidyl glycerol, phosphatidyl choline, phosphatidyl inositol and phosphatidic acid in Trichophyton rubrum. At higher concentration, however UDA inhibits biosynthesis of all phosphatides present in this dermatophyte. UDA also affects catabolism of these phosphatides. This inhibitory effect of UDA may be partially responsible for its toxic action on T. rubrum.

Sample Use Guides

In Vivo Use Guide
The combinations of tricyclodecan-9-yl-xanthogenate (D 609) with undecanoic acid (C11) and D 609 with myristic acid (C14) were tested in 3 rodent tumor models in vivo. In L 1210 mouse lymphoid leukemia growing in CD2F1 mice the combination of D 609/C11 given intraperitoneally in a concentration of 100 mg/kg for more than 1 day effected a significant difference in the survival curves between the control and therapeutic groups in 1 out of 2 experiments.
Route of Administration: Intraperitoneal
In Vitro Use Guide
Undecanoic acid (UDA) inhibited conidial germination of UDA sensitive (udas) wild type Trichophyton rubrum and UDA resistant (udar) mutant strains at 30 ug/ml and 120 ug/ml respectively which were minimum inhibitory concentrations of UDA for these two strains.
