Several nucleoside analogues are used as antiviral or anticancer agents. One study uncovered 199 novel cytotoxic compounds with anticancer potential. It is the prototype of alkylating agents, a group of anticancer chemotherapeutic drugs. In medicine several nucleoside analogues are used as antiviral or anticancer agents. In medicine, several nucleoside analogues are used as anticancer and antiviral agents. The compound was eventually demonstrated to have antiviral, antifungal, antibacterial, anticancer, and antipsoriasis activities. PARP1 inhibition has also been widely studied in anticancer therapeutics. The andrastins inhibit proteins involved in the efflux of anticancer drugs from multidrug-resistant cancer cells. Interactions between herbal medicines and anticancer drugs typically involve enzymes that metabolize cytochrome P450. Topoisomerase poisons have been extensively used as both anticancer and antibacterial therapies. Hence small molecule inhibitors of HSPs, especially Hsp90 show promise as anticancer agents. Furthermore, inhibition of autophagy has also been shown to enhance the effectiveness of anticancer therapies. After, they tested resveratrol in combination with several different known anticancer agents. Tylophorine is a type of plant-derived alkaloid with anticancer activity by inducing cell cycle arrest. Tamoxifen seems to require a protein PAX2 for its full anticancer effect.
