BACKGROUND
Malignacies are still a major public concern worldwide and despite the intensive search of new chemotherapeutic agents, treatment still remains a challenging issue. The present study was designed to evaluate the cytotoxicity of 2-acetyl-7-methoxynaphtho[2,3-b]furan-4,9-quinone (AMNQ)

On the basis of monitoring the inhibition of the growth of human cancer cells, a series of novel furan derivatives of possessing a broader spectrum of antitumor activity and fewer toxic side effects than traditional anticancer drugs have been studied. Ten selected furan derivatives were subjected to

Prisijungti Registracija
The PI3K/Akt/mTOR signaling pathway plays a key regulatory function in cell survival, proliferation, migration, metabolism and apoptosis. Aberrant activation of the PI3K/Akt/mTOR pathway is found in many types of cancer and thus plays a major role in breast cancer cell proliferation. In our previous
