Pseudolaric Acid B is an orally active diterpene acid. Pseudolaric Acid B has anti-fungal, anti-fertility, anti-angiogenesis and anticancer activity, and can induce tumor cell apoptosis and autophagy. In addition, Pseudolaric Acid B can inhibit the secretion of hepatitis B virus (HBV) and has immunosuppressive effect, selectively inhibiting the proliferation of T lymphocytes and the production of IL-2.

Ascr#3 is a type of pheromone found in the beautiful nematode, and when mixed with ascr#2, it can act as a male attractant and also induce the formation of dauer (the dormant larval stage). Ascr#3 can counteract the effects caused by male-enriched Ascr#10.

Swertisin is an oral adenosine A1 receptor antagonist and an SGLT2 inhibitor. Swertisin has anti-diabetic, antioxidant properties, inhibits HBV, and improves cognitive and memory impairments in mice.

Halofantrine hydrochloride (SKF-102886 hydrochloride; WR-171669 hydrochloride) is a blocker that delays the delayed rectifier potassium current by inhibiting human ERG channels, and it is a potent antimalarial agent with oral activity. Halofantrine hydrochloride inhibits the Cap1-dependent oxidative stress response of Candida albicans, suppresses ROS responses, and enhances the antifungal (Fungal) activity of oxidative damage agents. Halofantrine hydrochloride exhibits antifungal activity in the Galleria mellonella model, and shows antimalarial activity against Plasmodium strains both in vitro and in animal models. Halofantrine hydrochloride can be used in studies related to invasive candidiasis, falciparum malaria, and vivax malaria.

Enoxacin hydrate (Enoxacin sesquihydrate), a fluoroquinolone, interferes with DNA replication and inhibits bacterial DNA gyrase (IC₅₀=126 µg/ml) and topoisomerase IV (IC₅₀=26.5 µg/ml). Enoxacin hydrate is a miRNA processing activator and enhances siRNA-mediated mRNA degradation and promotes the biogenesis of endogenous miRNAs. Enoxacin hydrate has potent activities against gram-positive and -negative bacteria. Enoxacin hydrate is a cancer-specific growth inhibitor that acts by enhancing TAR RNA-binding protein 2 (TRBP)-mediated microRNA processing.

Nevadensin (Lysionotin), a natural flavonoid, is a selective human carboxylesterase 1 (hCE1) inhibitor with an IC₅₀ of 2.64 μM. Nevadensin is more selective for hCE1 than hCE2 (IC₅₀ of 132.8 μM). Nevadensin can induce apoptosis and DNA damage in cancer cells. Nevadensin has a variety of pharmacological effects such as anti-inflammatory, anti-tumour, anti-hypertensive, anti-tubercular, antitussive, antioxidant and anti-microbial activities.

Furaneol is mainly isolated from American grape (Vitis labrusca) and its hybrid grape. Furaneol is an important aroma compound in fruits and contribute to the strawberry-like note in some wines.
