Bruceantin is a compound isolated from Brucea antidysenteriea, a plant used in Ethiopia as an anticancer treatment. The primary action of Bruceantin appears to be an inhibition of protein synthesis which takes place at the ribosomal level. Bruceantin induced marked decreases of c-myc mRNA and protein expression in all cell lines. Bruceantin-induced c-myc downregulation might trigger cell death mechanisms preferentially in those cell lines with wild-type p53 protein expression. Bruceantin was evaluated in three separate phase I clinical trials in patients with various types of solid tumors. Hypotension, nausea, and vomiting were common side effects at higher doses, but hematologic toxicity was moderate to insignificant and manifested mainly as thrombocytopenia. Bruceantin was then tested in two separate phase II trials including adult patients with metastatic breast cancer and malignant melanoma. No objective tumor regressions were observed, and clinical trials were terminated.
Ginkgolide B belongs to the class of organic compounds known as ginkgolides and bilobalides. These are diterpene lactones with a structure based either on the gingkolide or the bilobalide skeleton. The ginkgolide skeleton is a very rigid structure consisting of hexacyclic C20 trilactone. The cis-fused F/A/D/C ring junction forms an empty semi-ball hole, the D ring contains a cage form tetrahydrofuran ring which occupies the center of the empty hole, and the oxygen atoms of the D,C and F ring and 10-hydroxyl group consist of an analogous crown ether structure. Ginkgolide B is one of the ginkgolides isolated from the leaves of the Ginkgo biloba tree. The Ginkgolide B is the most potent antagonist of platelet activating factor (PAF) and exhibits therapeutic action in a variety of diseases mainly by the PAF receptor. The ginkgolide B possesses a number of beneficial effects such as anti-inflammatory, anti-allergic, antioxidant, and neuroprotective effects. It promotes the proliferation, migration and adhesion of endothelial progenitor cells, and the induction of angiogenesis through vascular endothelial factor (VEGF). Ginkgolide B is considered a valid non-pharmacological (or nutraceutical) approach to the prophylaxis of both migraine with and without aura. Effects of ginkgolide B include reduction of Ca2+-stimulated intracellular events, scavenging of free radicals, modulation of central nervous system glutamatergic transmission and reduction of antiplatelet activating factor (PAF) levels in brain. Ginkgolide B is an active component of EGb, a standardised extract of Ginkgo biloba leaves. Ginkgolide B is one of the major components of EGb-761.

Smilagenin (also known as PYM50028 and Cogane) is a constituent of Jamaican sarsaparilla (Smilax ornata) and is a neuroprotectant that has been evaluated in Phase II clinical trials in Parkinson's disease and Alzheimer's disease. On 27 September 2011, the European Commission to Phytopharm plc, United Kingdom, granted orphan designation for smilagenin for the treatment of amyotrophic lateral sclerosis. The details of the mechanism of action of smilagenin are incomplete but involve the upregulation of neurotrophic factors including Glial cell line-derived neurotrophic factor and brain-derived neurotrophic factor.
Epichatechin is one of the 4 catechin diastereoisomers. It can be isolated from a number of species of Palmae, as well as Dryas octopetala and guarana seeds. Epicatechin has been widely studied as a potential therapeutic compound in a wide variety of conditions including cancers, diabetes, heart conditions, and neurological conditions. Epicatechin is available as a natural health supplement and marketed for bodybuilding and the treatment of high blood pressure, high cholesterol, immune support, low testosterone, high blood sugar, and improved memory.

Molidustat also was known as BAY 85-3934 is a novel inhibitor of hypoxia-inducible factor (HIF) prolyl hydroxylase (PH) which stimulates erythropoietin (EPO) production and the formation of red blood cells. Hypoxia-inducible factor (HIF) is the major transcription factor involved in erythropoietin gene expression. Because oxygen-dependent degradation of the α subunit of HIF suppresses erythropoietin expression, stimulation of erythropoiesis by agents that prevent degradation of HIF has been one strategy for managing anemia. Thus, molidustat is in phase II of a clinical trial to investigate the effects therapy in patients with renal anemia associated with chronic kidney disease and/or end-stage renal disease.

3,3′-diindolylmethane or diindolylmethane (DIM), a natural product from cruciferous vegetables, which possesses chemopreventive activity in all stages of breast cancer carcinogenesis and is under investigation for the different form of cancer. DIM selectively induced proteasome-mediated degradation of the class I histone deacetylases (HDAC1, HDAC2, HDAC3, and HDAC8) without affecting the class II HDAC proteins (HDAC4, 5, 6, 7, and 10). Histone deacetylases are components of high molecular weight multisubunit complexes of co-repressor proteins that are recruited by transcription factors to the promoters to regulate gene expression. In addition, was identified another mechanism of action: DIM suppressed cancer cells proliferation and miR-30e down-regulated during this effect. miR-30e targeted the 3'-UTR of ATG5 to inhibit its translation. Thus DIM may through the miR-30e-ATG5 modulating autophagy inhibit the proliferation of gastric cancer cells. DIM is also sold as absorption-enhanced formulation under the brand name Patented BioResponse DIM®. BioResponse DIM supports a more favorable metabolism of estrogen and supports the production of 2 hydroxyestrone and 2-methoxyestrone, key metabolites in men and women. DIM is used to treat recurrent respiratory papillomatosis and it has been studied for patients with cervical intraepithelial neoplasia.
