Lentinan je beta-glukan sa glikozidnim β-1,3:β-1,6 vezama.[1] On je antitumorni polisaharid iz šitake (Lentinula edodes) pečurke.[1] Lentinan je polisaharid sa molekulskom težinom od oko 500.000 Da. Japanska farmaceutska kompanija Ajinomoto je razvila lek Lentinan, koji se intravenozno dozira kao agens protiv kancera.[2]
Lentinan je jedan od lekova protiv kancera[3] za koji je pokazano da utiče na odbrambeni imunski sistem domaćina.[4]
Klinička israživanja na obolelima od raka su ukazala na vezu između lentinana i povišenog stepena perživljavanja, poboljšanog kvaliteta života, i umanjene ponovne pojave kancera.[5][6][7][8][9][10][11][12]
