Acemannan is a D-isomer mucopolysaccharide in aloe vera leaves. This compound has potential immunostimulant, [1] antiviral, antineoplastic, and gastrointestinal properties. [2]
Acemannan's monomer is mannoacetate linked by β-1,4- glycosidic bonds. [3] [4] This polymer is hydrophilic.
Acemannan has been demonstrated to induce macrophages to secrete interferon (IFN), tumor necrosis factor-α (TNF-α) and interleukins (IL-1); therefore, it might help to prevent or abrogate viral infection. These three cytokines are known to cause inflammation, and interferon is released in response to viral infections. In vitro studies have shown acemannan to inhibit HIV replication; however, in vivo studies have been inconclusive.
Acemannan is currently being used for treatment and clinical management of fibrosarcoma in dogs and cats. Administration of acemannan has been shown to increase tumor necrosis and prolonged host survival; the animals have demonstrated lymphoid infiltration and encapsulation. [5]
The compound has been found to have an LD50 of >80 mg/kg and LC50 >5,000 mg/kg IV. [6]
