Lentinan je beta-glukan sa glikozidnim β-1,3:β-1,6 vezama.[4] On je antitumorni polisaharid iz šitake (Lentinula edodes) pečurke.[4] 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.[5]
Lentinan je jedan od lekova protiv kancera[6] za koji je pokazano da utiče na odbrambeni imunski sistem domaćina.[7]
Klinička israživanja na obolelima od raka su ukazala na vezu između lentinana i povišenog stepena perživljavanja, poboljšanog kvaliteta života, i umanjene ponovne pojave kancera.[8][9][10][11][12][13][14][15]
