Cevipabulin is a synthetic, water-soluble tubulin-binding agent with potential antineoplastic activity. Cevipabulin appears to bind at the vinca-binding site on tubulin but seems to act more similar to taxane-site binding agents in that it enhances tubulin polymerization and does not induce tubulin depolymerization. The disruption in microtubule dynamics may eventually inhibit cell division and reduce cellular growth.

LAVOLTIDINE, also known as loxtidine, is a highly potent and selective histamine H2-receptor antagonist. It is a member of triazoles. It produces gastric carcinoid tumors in rodents that is why its clinical development was discontinued.

PF-2545920 is an orally-active phosphodiesterase 10A (PDE10A) inhibitor originated by Pfizer, for the treatment of Huntington's disease. PF-2545920 was originally developed by Pfizer for the treatment of schizophrenia. But later clinical studies for Schizophrenia were discontinued. PF-2545920 is a potent and selective PDE10A inhibitor with IC50 of 0.37 nM, with >1000-fold selectivity over the PDE. PF-2545920 is active in a range of antipsychotic models, antagonizing apomorphine-induced climbing in mice, inhibiting conditioned avoidance responding in both rats and mice, and blocking N-methyl-D-aspartate antagonist-induced deficits in prepulse inhibition of acoustic startle response in rats, while improving baseline sensory gating in mice.

Dazopride is an antagonist of the 5-HT3 receptor and agonist of the 5-HT4 receptor, structurally related to metoclopramide. Dazopride was developed by A. H. Robins Company as an antiemetic and gastroprokinetic drug. Dazoptide demonstrated an antiemetic effect in the clinic after i.v. infusion to patients, receiving anticancer therapy.

Dehydroandrographolide (DP) from Andrographis paniculata (Burm. F.) Nees is a potential anticancer agent which can act, in part, through the inhibition of TMEM16A expression and may support TMEM16A as a novel target for antitumor therapy in TMEM16A-amplified cancers. It was shown that DP inhibits the invasion of human oral cancer cells and is a potential chemopreventive agent against oral cancer metastasis. It is also used for the treatment of infections in China. However, DP has not been found to significantly inhibit bacterial and viral growth directly. It was discovered that the DP enhanced innate immunity of intestinal tract through increased expression of human β -defensin-2 (hBD-2) through the p38 MAPK pathways. Dehydroandrographolide also possesses activity against hepatitis B virus
