10-Hydroxy-2-decenoic acid

Description

10-HDA is an unsaturated fatty acid found in royal jelly produced from the hypopharyngeal and mandibular gland secretions of honeybees. 10-HDA has longevity-promoting effects in C. elegans at a concentration of 25 μM. It down-regulates matrix metalloproteinases (MMPs) in rheumatoid arthritis synovial fibroblasts at a concentration of 1.25 nM and inhibits VEGF-induced angiogenesis in HUVECs at 500 μM. 10-HDA also facilitates differentiation of neurons from neural stem/progenitor cells and promotes collagen production by skin fibroblasts at concentrations of 100 μM and 1.5 mM, respectively.

The Uses of 10-Hydroxy-2-decenoic acid

10-Hydroxy-2-decenoic acid has antiseptic, anti-inflammatory, anti-obesity, anti-aging, preventing bone loss and anti-tumour pharmacological effects, with potential therapeutic effects for postmenopausal osteoporosis, as well as benefiting the human gastrointestinal tract^[1-3].

What are the applications of Application

Royal Jelly acid is an inhibitor of VEGF-induced angiogenesis, cell migration and proliferation

Definition

ChEBI: (E)-10-hydroxydec-2-enoic acid is an omega-hydroxy amino acid that is 2-decenoic acid in which one of the hydrogens attached to the terminal carbon is replaced by a hydroxy group and in which the C=C double bond has E configuration. It is a component of royal jelly. It has a role as an animal metabolite and a geroprotector. It is an alpha,beta-unsaturated monocarboxylic acid, a straight-chain fatty acid, a hydroxy monounsaturated fatty acid and an omega-hydroxy-medium-chain fatty acid.

Biological Activity

10-Hydroxy-2-decenoic acid is an orally available royal jelly component that potently inhibits osteoclastogenesis. It binds to free fatty acid receptor 4 (FFAR4) on osteoclasts which inhibits RANKL (receptor activator of nuclear factor-κB (NF-κB) ligand), thereby attenuating the induction of nuclear factor of activated T cells (NFAT) c1. 10-Hydroxy-2-decenoic acid inhibits bone resorption in ovariectomized mice.
The production of pro-inflammatory cytokines, Interleukin (IL)-8, IL-1β and tumor necrosis factor-alpha (TNF-α) in WiDr cells was modulated by 10-HDA. IL-8 were dramatically declined by 10-HDA at 3 mM, while IL-1β and TNF-α were significantly decreased. 10-HDA increased IL-1ra in a dose manner. NF-κB pathway is primarily in response to prototypical pro-inflammatory cytokines, and NF-κB was reduced after 10-HDA treatment. 10-HDA acted as potent bactericide against animal- or human-specific pathogens, including Staphylococcus aureus, Streptococcus alactolyticus, Staphylococcus intermedius B, Staphylococcus xylosus, Salmonella cholearasuis, Vibro parahaemolyticus and Escherichia coli (hemolytic)^[1].
