Sapanisertib is an oral dual inhibitor of mTORC1/mTORC2, discovered by Intellikine for the treatment of cancer. The drug is being tested in phase II of clinical trials for different cancers among which are sarcoma, hepatocellular carcinoma, etc. The drug is currently developed by Takeda with breast cancer, renal cancer and endometrial cancer being the main target indications.

Phosphorylcholine (ChoP) is a small zwitterionic amino alcohol, which is composed of a negatively charged phosphate bonded to a small, positively charged choline group. Phosphorylcholine is the precursor metabolite of choline in the glycine, serine, and threonine metabolism pathways and in intermediate between choline and cytidine-diphosphate choline in the glycerophospholipid metabolism pathway. Phosphorylcholine is an interesting compound from an immunologic point of view, being an immunodominant determinant of pneumococcal teichoic acids and also a major prerequisite for proinflammatory effects of PAF and PAF-like lipids where PC is a common denominator. PC is also a component of some bacteria, apoptotic cells, and OxLDL, which, if exposed, is immunogenic. PC has several properties that could in principle both promote and protect against disease, depending on the pathogen and type of inflammatory reaction. In the field of interventional cardiology, phosphorylcholine is used as a synthetic polymer-based coating, applied to drug-eluting stents, to prevent the occurrence of coronary artery restenosis. To date, more than 120,000 Phosphorylcholine-coated stents have been implanted in patients with no apparent deleterious effect in the long term compared to bare metal stent technologies

Heidelberg Pharma Research developed fosalvudine tidoxil, a prodrug derived from the nucleoside reverse transcriptase inhibitor alovudine, for the treatment of HIV infections. This drug had reached phase II clinical trials before its development was discontinued.

PSI-352938 is a nucleoside derivative patented by Pharmasset, Inc. as an antiviral agent. PSI-352938 acts as a novel cyclic phosphate prodrug of β-D-2'-deoxy-2'-α-fluoro-2'-β-C-methylguanosine-5'-monophosphate with potent anti-HCV activity. PSI-352938 inhibits HCV genotype (GT) 1b replicon replication with 50% effective concentrations (EC50s) of 0.13 ± 0.076 μM, and active against GT 1a and 2a replicons and infectious viruses PSI-352938 retained full activity against replicons containing the S282T substitution, which confers resistance to certain 2'-substituted nucleoside/nucleotide analogs. In April 2013, because of hepatic toxicity, Gilead Sciences discontinued the development of PSI-352938.

Vapendavir (BTA-798) is an orally active capsid-binding inhibitor. It is a potent, orally bioavailable, broad spectrum inhibitor of the large group of HRVs. Vapendavir binds tightly to VP1s canyon and disrupts the ability of the capsid to bind to a specific cell surface receptor. This further inhibits the release of the viral RNA into the cell cytoplasm during the viral uncoating process (removing the lipid bilayer), thereby disrupting viral replication. Vapendavir is designed to be dosed orally. Vapendavir is in phase II clinical trials for the treatment of rhinovirus-induced aggravation of pre-existing asthma or COPD. Vapendavir has shown significant results in proof-of-concept studies. Thus far, from the Phase 1/2 studies conducted, vapendavir has demonstrated a desirable clinical pharmacology profile with high bioavailability, linear pharmacokinetic profile, remained unaffected by concomitant medications, and was not exclusively metabolized.

Pfizer developed fosdagrocorat (PF-04171327), a dissociated agonist of the glucocorticoid receptor for the treatment of rheumatoid arthritis. The drug successfully completed the phase II clinical trial; however, further study of the drug was discontinued.

PF-04217903 is a triazolopyrazine inhibitor of c-MET that displays anticancer chemotherapeutic and anti-metastatic activities. PF-04217903 inhibits cell proliferation, invasion, and migration as well as tumor growth in various cancer models. In animal models of pancreatic neuroendocrine tumors, this compound prevents lymph node metastasis. PF-04217903 had been in phase I clinical trials by Pfizer for the treatment of solid tumors. In 2011, the company discontinued the development of the compound.

Dimetholizine has antihypertensive activity. It is an antihistaminic agent too. Histamine H1 receptor was predicted as a primary target for dimetholizine. Moreover, it was found to bind the Dopamine D2 and 5-HT1A receptors. Dimetholizine was predicted to be alpha1D-Adrenergic blocker.

Dipraglurant (ADX48621) is a novel, potent mGluR5 negative allosteric modulator that reduced the severity of drug-induced dyskinesia in Parkinson's disease. Dipraglurant pharmacokinetic variables were similar to those of levodopa, suggesting that both drugs can be co-administered simultaneously in further studies. Dipraglurant might be useful in torsion dystonia treatment also. Detected adverse events are: sweating, dyskinesia, nausea, dizziness, and anxiety. One serious adverse event described as possible syncope.
