Vatalanib a potent oral tyrosine kinase inhibitor with a selective range of molecular targets, has been extensively investigated and has shown promising results in patients with solid tumors in early trials. Vatalanib selectively inhibits the tyrosine kinase domains of vascular endothelial growth factor (VEGF) receptor tyrosine kinases (important enzymes in the formation of new blood vessels that contribute to tumor growth and metastasis), platelet-derived growth factor (PDGF) receptor, and c-KIT. The adverse effects of vatalanib appear similar to those of other VEGF inhibitors. In the CONFIRM trials, the most common side effects were high blood pressure, gastrointestinal upset (diarrhea, nausea, and vomiting), fatigue, and dizziness.

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).

Vinconate possesses both encephalotropic and psychotropic properties. Animal experiments have shown that this compound could induce the facilitation of phosphatidylinositide (PI) turnover via the stimulation of muscarinic acetylcholine receptors. In addition, vinconate could lead to the direct activations of PIP2-specific and cytosolic phospholipase C. The drug was on the stage of preregistration for the treatment of cognition disorders in Japan. However, information about the further fate of this drug is not available.

Glesatinib (MGCD265) is an orally bioavailable, small-molecule, multitargeted tyrosine kinase inhibitor with potential antineoplastic activity. Glesatinib binds to and inhibits the phosphorylation of several receptor tyrosine kinases (RTKs), including the c-Met receptor (hepatocyte growth factor receptor); the Tek/Tie-2 receptor; vascular endothelial growth factor receptor (VEGFR) types 1, 2, and 3; and the macrophage-stimulating 1 receptor (MST1R or RON). Inhibition of these RTKs and their downstream signaling pathways may result in the inhibition of tumor angiogenesis and tumor cell proliferation in tumors overexpressing these RTKs. Studies in a gastric cancer xenograft model revealed that, in addition to the typically reported cellular activities, glesatinib in combination with erlotinib disrupted the glycolysis pathway, suggesting a novel mechanism of action for this drug. Glesatinib has been studied in a variety of advanced solid tumors including NSCLC, as a monotherapy and in combination with either docetaxel or erlotinib. In an ongoing phase 1 study in patients with MET positive or AXL-rearranged advanced solid tumors, glesatinib demonstrated preliminary single-agent activity, with all three patients with MET dysregulated NSCLC (two with METex14 alterations and one with increased GCN) showing significant tumor regression at the first assessment. A phase 2 study is currently recruiting patients with MET-dysregulated (mutated or amplified) advanced or metastatic NSCLC.

Norcodeine is the N-demethylated derivative of codeine. It has relatively little opioid activity in its own right, but is formed as a metabolite of codeine following ingestion. Codeine and its other major metabolites codeine-6-glucuronide and norcodeine have weak affinity to opioid μ-receptors.

Ipatasertib, an investigational Akt inhibitor, is currently in clinical development based on its potential to specifically target Akt in tumors with activated Akt signaling. Preclinical data have shown that ipatasertib selectively decreased cell viability and increased apoptosis in tumor cell lines characterized by activated Akt. Ipatasertib is advancing in clinical development including three Phase 2 trials in patients with breast cancer, gastric cancer and prostate cancer. The most commonly reported adverse events associated with Ipatasertib were Grade 1-2 diarrhea, nausea, fatigue, vomiting, decreased appetite and rash.

Inspyr Therapeutics (formerly GenSpera) developed mipsagargin (previously known as G-202), as a novel thapsigargin-based targeted prodrug that is activated by prostate-specific membrane antigen (PSMA)-mediated cleavage of an inert masking peptide. The active moiety is an inhibitor of the sarcoplasmic/endoplasmic reticulum calcium adenosine triphosphatase (SERCA) pump protein that is necessary for cellular viability. Mipsagargin was granted Orphan Drug designation by the U.S. Food and Drug Administration (FDA) in 2013 for evaluation in patients with hepatocellular carcinoma. In addition, mipsagargin has been studied in phase 2 clinical trial in patients with recurrent or progressive glioblastoma, in patients with clear cell renal cell carcinoma that expresses PSMA. Mipsagargin is expected to be launched on the market in the coming years.

Sodium sulfanilate is a salt of sulphanilic acid and has been used to monitor the degree of renal dysfunction in dogs.

Setastine (Loderix) is a potent antagonist of histamine H1-receptor mediated responses. Setastine inhibits anaphylactic shock in guinea-pigs sensitized by horse serum. No antiserotonin, anticholinergic and antiadrenergic effect of the compound can be detected. Setastine has a long lasting (up to 16 h) antihistamine effect with a good oral effectiveness. It shows no cardiovascular effects in cats. Setastine shows a much weaker CNS depressant activity than clemestine fumarate. In displacement studies (3H-mepyramine) setastine had significantly weaker affinity for the central nervous system (CNS) H1-receptors than clemastine fumarate. It is concluded that setastine is a non-sedative highly active H1-antagonist.
