Piritrexim is a synthetic antifolate agent with antiparasitic, antipsoriatic and antitumor properties. Piritrexim inhibits the enzyme dihydrofolate reductase, thereby disrupting folate metabolism and DNA synthesis and cell division. A theoretical advantage of piritrexim over trimetrexate is a lack of any known effects on histamine metabolism, which may lower the risk of hypersensitivity reactions. Piritrexim is a nonclassical antifolate for antitumor and parasitic chemotherapy that passively diffuses into cells and hence do not have to depend on folylpoly-gamma-glutamate synthetase or the reduced folate carrier. Because piritrexim is not a substrate for polyglutamation, the drug is not selectively retained within cells for prolonged periods. Piritrexim has a reliably high oral bioavailability of about 75%, which has led to its development as an oral lipophilic antifolate. Most commonly, it has been administered in oral daily doses of 75 to 150 mg bid or tid every 5 days, with cycles repeated every 3 weeks. Oral absorption is rapid, with peak plasma levels appearing at 1.5 hours after ingestion. Elimination occurs primarily via hepatic metabolism of the drug to active metabolites, and the terminal half-life of the parent compound is about 1.5 to 4.5 hours. Single-agent oral piritrexim has clinical activity in melanoma, urothelial cancers, and head and neck cancers. Tolerable combinations of piritrexim with cisplatin, fluorouracil, and leucovorin have been tested, with promising results achieved in head and neck cancer. An interesting attempt to alternate piritrexim with methotrexate did not have any greater activity than methotrexate alone.

Gluceptate sodium also known as sodium glucoheptonate (H-Quest A300) is a non-toxic, a non-hazardous chelating agent, which forms stable complexes with di- and trivalent metal ions such as Ca2+, Fe2+, Fe3+, Al3+, etc. This substance is highly compatible with strong alkaline mediums and can prevent the bacterial degradation of the solution. Gluceptate sodium has various applications in water treatment, agricultural, cosmetics, textile processing and in some others fields.

Hycanthone is a thioxanthene derivative of lucanthone with anti-schistosomal activity and potential antineoplastic activity. It was clinically available for the treatment of human schistosomiasis. Anti-helmintic action relies on its ability to inhibit worm monoamine oxidase and cholinesterases. Hycanthone produced immediate side effects such as hepatotoxicity and gastrointestinal disturbances, and was consequently withdrawn. Hycanthone inhibits apurinic endonuclease-1 (APE1) by direct protein binding. Hycanthone was used in the 1980s as antitumor agents, it was pulled out of Phase II trials.

Indolapril (CI-907) is a new orally active prodrug of nonsulfhydryl angiotensin-converting enzyme (ACE) inhibitor, developed by Warner-Lambert/Parke-Davis Pharmaceutical Research for treating hypertension. Indolapril is epimer of trandolapril, well-known ACE inhibitor currently in the market for hypertension treatment. Indolapril (Monoester form) and it’s active component (diacid form) produced concentration related ACE inhibition in guinea-pig serum (IC50 for monoester -- 0.1 mkM and for diacid -- 2.6 nM). In isolated rabbit aortic rings and in rat and dog autonomic studies, Indolapril is highly specific in suppressing the contractile or pressor responses to angiotensin I. In two-kidney, one-clip Goldblatt hypertensive rats, single daily doses (0.03-30 mg/kg p.o.) produced dose-dependent decreases in blood pressure; 3 mg/kg lowered blood pressure to normotensive levels. In the spontaneously hypertensive rat, subacute administration of Indolapril produced the same decrease in blood pressure as that obtained in the renal hypertensive rat. In diuretic-pretreated renal hypertensive dogs, 10 mg/kg normalized blood pressure. For equivalent drops in blood pressure, heart rate increases were less in Indolapril than in enalapril-treated renal hypertensive dogs. No side effects were observed with CI-907 in any of the conscious animals. The antihypertensive response to Indolapril (0.03-1.0 mg/kg p.o.) was found to correlate with inhibition of vascular tissue ACE, but not plasma or brain ACE in two-kidney, one-clip renal hypertensive rats.

Onalespib (AT13387; (2,4-dihydroxy-5-isopropyl-phenyl)-[5-(4-methyl-piperazin-1-ylmethyl)-1,3-dihydro-isoindol-2-yl] methanone, l-lactic acid salt), is wholly owned by Astex, a novel, high-affinity HSP90 inhibitor, which is currently being clinically tested, has shown activity against a wide array of tumor cell lines, including lung cancer cell lines. As a targeted inhibitor of Hsp90, onalespib has the potential to control the proliferation of multiple solid tumors and hematological malignancies where uncontrolled cell growth is dependent on the interaction between Hsp90 and its client proteins. Astex is pursuing an approach based on the observation that addition of onalespib to a molecularly targeted agent may delay the emergence of resistance to the agent, and hence prolong the window of therapeutic benefit. Onalespib is currently being evaluated via a CRADA with the National Cancer Institute (NCI) in various tumor types, and in a Phase 1/2 clinical study in combination with AT7519, Astex CDK inhibitor.

Semapimod (CNI-1493) is a cytokine inhibitor and synthetic guanylhydrazone mitogen-activated protein kinase blocker, is being developed by Cytokine PharmaSciences as a potential treatment for Crohn's disease and other inflammatory conditions. As of December 2001, a phase I study demonstrating the safety of the compound had been completed and phase II trials for psoriasis and Crohn's disease were ongoing. In April 2003, preclinical and early clinical studies were underway for a variety of indications, including congestive heart failure and pancreatitis. Semapimod inhibits activation of p38 MAPK and NF-κB and induction of cyclooxygenase-2 by TLR ligands, but not by IL-1β or stresses. Semapimod inhibits TLR4 signaling (IC50 ≈0.3 umol) and acts by desensitizing cells to LPS; it fails to block responses to LPS concentrations of ≥5 ug/ml. Semapimod had been in phase II clinical trials by Ferring Pharmaceuticals for the treatment of Crohn's disease. However, this research has been discontinued. Semapimod is in phase I clinical trials for the treatment of autoimmune disorders and inflammation.

Lysergide (LSD) is a semi-synthetic hallucinogen and is one of the most potent drugs known. Recreational use became popular between the 1960s to 1980s, but is now less common. LSD was first synthesized by Albert Hoffman while working for Sandoz Laboratories in Basel in 1938. Some years later, during a re-evaluation of the compound, he accidentally ingested a small amount and described the first ‘trip’. During the 1950s and 1960s, Sandoz evaluated the drug for therapeutic purposes and marketed it under the name Delysid®. It was used for research into the chemical origins of mental illness. Recreational use started in the 1960s and is associated with the ‘psychedelic period’. LSD possesses a complex pharmacological profile that includes direct activation of
serotonin, dopamine and norepinephrine receptors. In addition, one of its chief sites of
action is that of compound-specific (“allosteric”) alterations in secondary messengers
associated with 5HT2A and 5HT2C receptor activation and changes in gene expression.
The hallucinogenic effects of LSD are likely due to agonism at 5HT2A and 5HT2C
receptors. LSD is also an agonist at the majority of known
serotonin receptors, including 5HT1A, 5HT1B, 5HT1D, 5HT5A, 5HT6 and 5HT7 receptors. During the 1960s, LSD was investigated for a variety of psychiatric indications, including the following: as an aid in treatment of schizophrenia; as a means of creating a "model psychosis"; as a direct antidepressant; and as an adjunct to psychotherapy. LSD is listed in Schedule I of the United Nations 1971 Convention on Psychotropic Substances.

Raxatrigine also known as GSK1014802 and CNV-1014802, is a novel analgesic under development by Convergence Pharmaceuticals for the treatment of lumbosacral radiculopathy (sciatica) and trigeminal neuralgia (TGN). It is a novel state dependent small molecule sodium channel blocker that preferentially inhibits the Nav 1.7 ion channel, a therapeutic target implicated by genetics in human pain conditions. Raxatrigine is thought to penetrate the central nervous system and block Nav channels in a novel manner. CNV1014802 was granted orphan drug designation in 2013 by the US Food and Drug Administration (FDA) for the treatment of trigeminal neuralgia.
