Amentoflavone is a biflavonoid that is obtained by oxidative coupling of two molecules of apigenin resulting in a bond between positions C-3 of the hydroxyphenyl ring and C-8 of the chromene ring. A natural product found particularly in Ginkgo biloba and Hypericum perforatum. It has a role as an antiviral agent, an angiogenesis inhibitor, a P450 inhibitor, a cathepsin B inhibitor and a plant metabolite. It is a hydroxyflavone, a ring assembly and a biflavonoid. Amentoflavone is a novel natural inhibitor of human Cathepsin B(CatB), which has antifungal , antioxidant, antiviral, antidiabetic, and neuroprotective activities, it stimulates apoptosis in HSFBs and inhibits angiogenesis of endothelial cells, it is a promising molecule that can be used in hypertrophic scar treatment. Amentoflavone regulated β-catenin and caspase-3 expressions, and inhibited NF-κB signal transduction pathways. Amentoflavone (Didemeethyl ginkgetin) is an effective and orally active GABA (A) negative regulator. Amentoflavone also exhibits anti-inflammatory, antioxidant, antiviral, anti-tumor, anti radiation, and antibacterial activities. Amentoflavone induces cell apoptosis and cell cycle arrest in the sub-G1 phase.

N-methylnicotinate is an iminium betaine that is the conjugate base of N-methylnicotinic acid, arising from deprotonation of the carboxy group. It has a role as a plant metabolite, a food component and a human urinary metabolite. It is an alkaloid and an iminium betaine. It is functionally related to a nicotinate. It is a conjugate base of a N-methylnicotinic acid. Trigonelline (1-methylpyridinium-3-carboxylate), an alkaloid present in coffee and fenugreek seed, exhibits phytoestrogenic, anti-adipogenesis, and anticancer activities, it also can reduce early glucose and insulin responses. Trigonelline has inhibition of the Nrf2 transcription factor and PPAR-γ.

Cytarabine is a pyrimidine nucleoside in which cytosine is attached to D-arabinofuranose via a beta-N1-glycosidic bond. Used mainly in the treatment of leukaemia, especially acute non-lymphoblastic leukaemia, cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. It also has antiviral and immunosuppressant properties. It has a role as an antiviral agent, an antimetabolite, an antineoplastic agent and an immunosuppressive agent.
