: Resistance of cancer cells to therapy is a challenge for achieving an appropriate therapeutic outcome. Cancer (stem) cells possess several mechanisms for increasing their survival following exposure to toxic agents such as chemotherapy drugs, radiation as well as immunotherapy. Evidences show that apoptosis plays a key role in response of cancer (stem) cells and their multi drug resistance. Modulation of both intrinsic and extrinsic pathways of apoptosis can increase efficiency of tumor response and amplify the therapeutic effect of radiotherapy, chemotherapy, targeted therapy and also immunotherapy. To date, several agents as adjuvant have been proposed to overcome resistance of cancer cells to apoptosis. Natural products are interesting because of low toxicity on normal tissues. Resveratrol is a natural herbal agent that has shown interesting anti-cancer properties. It has been shown to kill cancer cells selectively, while protecting normal cells. Resveratrol can augment reduction/oxidation (redox) reactions, thus increases the production of ceramide and the expression of apoptosis receptors such as Fas ligand (FasL). Resveratrol also triggers some pathways which induce mitochondrial pathway of apoptosis. On the other hand, resveratrol has an inhibitory effect on anti-apoptotic mediators such as nuclear factor κ B (NFκB), cyclooxygenase-2 (COX-2), phosphatidylinositol 3–kinase (PI3K) and mTOR. In this review, we explain the modulatory effects of resveratrol on apoptosis, which can augment the therapeutic efficiency of anti-cancer drugs or radiotherapy.

In the last four decades, the emphasis was laid on the research of small organic molecules with potential anti-cancer activity. Linezolid was the first oxazolidinone derivative approved by FDA for MRSA treatment. Despite its major role in antimicrobial activity, these molecules display other properties, also serving as an antitumor agent. The importance of drug repurposing could be highlighted by the use of Oxazolidinone derivatives in pre-clinical studies, which are able to act through different pathways, such as partial agonist of transcription factor PPAR-γ, an inhibitor of key enzymes related to hormone-dependent disorders and even on sphingolipid metabolism as well. The purpose of this short review is to discuss the application of oxazolidinone derivatives as an antitumor agent by highlighting the most promising molecules studied by many research groups worldwide. Main biological activity against several tumor cell lines, including hematopoietic and solid cancer cell lines have been discussed. In addition, this study intends to report how different types of oxazolidinone derivatives can act as antitumor agents describing their distinct mechanisms of action based on their targets.
