Activating receptors are involved in antiviral and antitumor immunity. Lupeol has a complex pharmacology, displaying antiprotozoal, antimicrobial, antiinflammatory, antitumor and chemopreventive properties. Oleanolic acid is relatively non-toxic, hepatoprotective, and exhibits antitumor and antiviral properties. Podophyllotoxin derived antitumor agents include etoposide and teniposide. They show antibacterial, antifungal, antitumor and anti-inflammatory properties. Several studies show mebendazole exhibits potent antitumor properties. These three are widely used as antitumor and antimicrobial agents. It is also known to have wound healing, antitumor, and antithrombotic properties. It is an antitumor and antiangiogenic agent with oral bioavailability. Cells from the immune system also make crucial contributions to the antitumor effects of chemotherapy. The first phase involves the initiation of an antitumor immune response. Anthramycin is a pyrrolobenzodiazepine antibiotic with antitumor activity. CBC has shown antitumor effects in breast cancer xenoplants in mice. Research on antitumor activity of cucurbitacin focuses on four main variants of this molecule. Doxorubicin is in the anthracycline and antitumor antibiotic family of medications.
