Puerarin (7, 4’-dihydroxyisolavone-8-β-glucopyranoside) is an active isoflavone extracted from the roots of Pueraria lobata (Willd.) Ohwi. Puerarin is widely used in traditional Chinese medicine, and is clinically used in China for the treatment of coronary artery disease, heart failure, hypertension and myocardial infarction. It has been reported that puerarin had therapeutic effects on diabetes mellitus, arteriosclerosis and myocardial ischemia in animals. Puerarin demonstrated beta-adrenergic receptor blocking effect. On the other hand, puerarin stimulated alpha1-adrenoreceptor to increase glucose uptake into cultured C2C12 cells of mice. Puerarin has been investigated for the treatment (phase II clinical trials) of Alcohol Abuse, Rheumatoid Arthritis and Hypertension.

Gemcitabine elaidate is an ester of anticancer drug gemcitabine and elaidic fatty acid. The motivation to make an ester was to facilitate gemcitabine uptake and prolong retention in the cell. The drug is converted to parent compound gemcitabine both inside and outside the cell. Gemcitabine elaidate was developed by Clavis Pharma for treatment of solid tumors, including non-small cell lung cancer and pancreatic cancer, but its development was discontinued after product missed the primary endpoint in the Phase II LEAP trial to treat metastatic pancreatic cancer.

Galeterone (TOK-001, formerly called VN/124-1) is a potent anti-androgen with three modes of action. The compound acts as a specific androgen receptor antagonist, inhibits CYP17 lyase while conserving CYP17 hydroxylase function, and decreases overall androgen receptor levels in prostate cancer cells. Galeterone is a first in class, multi-targeted small-molecule drug that disrupts the growth and survival of prostate cancer cells. Tokai Pharmaceuticals is developing galeterone as an oral treatment for castration-resistant prostate cancer. Phase III clinical development of galeterone is underway in the US, Canada, Australia, Western Europe, Spain and the United Kingdom.

Naltalimide (TRK-130), a mu opioid receptor partial agonist, is being developed by Toray Industries for the treatment of overactive bladder. A phase IIb trial is underway in Japan. In radioligand-binding assays with cells expressing human µ-opioid receptors (MORs), δ-opioid receptors (DORs), or κ-opioid receptors (KORs), TRK-130 showed high selectivity for MORs (Ki for MORs, DORs, and KORs = 0.268, 121, and 8.97 nM, respectively). TRK-130 is a potent and selective human MOR partial agonist without undesirable opioid adverse effects such as constipation and enhances the storage function by suppressing the afferent limb of the micturition reflex pathway.

Mafodotin (mc-MMAF) is a hydrophilic non-cleavable antimicrotubule and antimitotic agent, monomethyl auristatin F (MMAF) derivative, having a maleimidocaproyl linker (mc linker), which is ready to conjugate to an antibody or other proteins or biopolymers. Antibody-drug conjugates having mafodotin such as Depatuxizumab mafodotin and Belantamab mafodotin have undergone clinical trials for the treatment of neoplasms.

17α-ethynyl-5α-androstane-3α, 17β-diol (HE3235, Apoptone) is an orally bioavailable synthetic analogue of 3β-androstanediol, that is active in rodent models of prostate and breast cancer. HE3235 is a second generation antitumor agent that causes apoptosis. It is an androgen receptor antagonist. HE3235 inhibits the BCL2 gene which translates proteins that prevent apoptosis and stimulates the expression proteins that induce apoptosis. HE3235 also downregulates the gene that codes for the multi-drug resistant protein ABCG2 (BCRP1 – Breast Cancer Resistance Protein1). Apoptone was in Phase I/II trials to treat hormone-refractory prostate cancer. However, the development has been discontinued.

Chlorogenic acid is the ester of caffeic acid and (-)-quinic acid. Chlorogenic acid is a naturally occurring plant metabolite and can be found with the related compounds cryptochlorgenic acid and neochlorogenic acid in the leaves of Hibiscus sabdariffa, coffee, potato, eggplant, peaches, and prunes. Chlorogenic acid has been investigated as a dietary supplement to improve glucose intolerant hypoglycemia and non-alcoholic fatty liver disease. It has also been identified as a potential anticancer agent by reducing the expression of HIF-1a and Sphingosine Kinase-1. Chlorogenic acid was also identified as a neuraminidase blocker effective against influenza A virus (H1N1 and H3N2).

Remogliflozin is the active component of the pro-drug remogliflozin etabonate, which is used the treatment of non-alcoholic steatohepatitis ("NASH") and type 2 diabetes. Remogliflozin inhibits the sodium-glucose transport proteins (SGLT), is selective for SGLT2, which is responsible for glucose reabsorption in the kidney. Blocking this transporter causes blood glucose to be eliminated through the urine.
