Antimicrobial and antitumoral activities of 6-allyl-5,6-dihydro-5-hydroxypyran-2-one, a lactone produced by a new Drechslera species.
Antifungal, antibacterial and antitumoral properties of 6-allyl-5,6-dihydro-5-hydroxypyran-2-one were researched. This compound was isolated from culture medium of a new Drechslera species from the area of the Dead Sea. The product exhibited a large activity spectrum against microorganisms, with interesting IC 50 values close to those obtained with reference compounds (kanamycin and ketoconazole). Antitumoral potentiality was 10 to 58 times less important than with doxorubicin, however IC 50 obtained were below 4 micrograms/ml, which is the threshold value proposed by National Cancer Institute for preliminary screening of active molecules.
