Cipemastat (Ro 32-3555, tentative trade name Trocade) is a dipeptide, potent, competitive inhibitor of matrix metalloproteinases (MMP) 1, 8 and 13, which was under development by Roche for the potential treatment of rheumatoid arthritis. Cipemastat is a selective inhibitor of metalloproteinases 1, 8 and 13 over the related human matrix metalloproteinases stromelysin 1, and gelatinases A and B. Cipemastat mediated MMP inhibition leads to block the final common event in the destructive cascade resulting in the breakdown of cartilage and bone. Trocade has also been shown to inhibit cartilage destruction in vivo and to prevent structural joint damage in animal models of rheumatoid and osteoarthritis. Cipemastat was in phase II clinical trials for the treatment of rheumatoid arthritis. However, Roche discontinued the development of cipemastat because of an unfavorable risk-benefit profile.

2-(1-Hexyloxyethyl)-2-devinyl pyropheophorbide-a (HPPH), a chlorin-based photosensitize, is used in photodynamic therapy. It has been shown the therapeutic potential of HPPH in phase II clinical trials for the treatment of esophageal cancer. Besides, HPPH participated in clinical trials in treating patients with advanced non-small cell lung cancer that blocks the air passages. However, these studies were terminated.

Lapachone (aka beta-Lapachone) is an ortho naphthoquinone, originally isolated from a tree whose extract has been used medicinally for centuries. It has garnered interest as a potential therapeutic or lead compound against a number of disease conditions including cancers, and blindness due to retinopathy of prematurity. It is lethal to a number of cancer cell types at micromolar concentrations, and it is capable of enhancing the efficacy of radiation therapies against cultured cells. A number of clinical trials have been conducted.

Conditions:

Indiplon is a nonbenzodiazepine, hypnotic sedative that was proposed for the treatment of insomnia. It is a high-affinity allosteric potentiator of GABAA responses that demonstrates preference for α1 subunit-containing GABAA receptors. There is minimal potential for adverse effects, residual daytime sedation, tolerance, respiratory depression. The simultaneous administration of indiplon and alcohol did not result in any significant pharmacokinetic changes. There is little risk of pharmacokinetic interaction between indiplon and any co-administered drugs. Developer (Neurocrine) decided to discontinue all clinical and marketing development of Indiplon in the United States.

Bryostatin 1 is a macrocyclic lactone which can be isolated from the marine bryozoan, Bugula neritina. The effects of bryostatin 1 are attributed to its ability to selectively modulate the activity of two of the three subgroups of protein kinase C (PKC) isozymes. PKC isozymes are divided into three subgroups which differ in their molecular structures and co-factor requirements: classical PKC (cPKC), novel PKC (nPKC), and atypical PKC (aPKC). Bryostatin-1 modulates nPKC activity independent of a Ca2+ signaling. It activates cPKC only when associated with Ca2+ signaling. And, aPKC activity is not sensitive to bryostatin-1 administration. Ca2+ signals play an important role in synaptic transmission and information processing which creates a biological environment where Bryostatin-1 possesses a unique action profile. Bryostatin-1 will not affect cPKC activity in neurons which are not functioning as an active part of the signaling processing circuit with significant Ca2+influx and intracellular Ca2+ release. Bryostatin 1 is in phase II clinical trials for investigation as an anticancer agent; specifically for treatment of metastatic or recurrent head and neck cancer, ovarian epithelial cancer that has not responded to previous chemotherapy, and myelodysplastic syndrome. Bryostatin 1 has also generated interest as an investigational compound for the treatment of Alzheimer's disease.

Faropenem medoxomil is an ester prodrug derivative of the beta-lactam antibiotic faropenem. The prodrug form of faropenem offers dramatically improved oral bioavailability and leads to higher systemic concentrations of the drug. Faropenem medoxomil is a broad-spectrum antibiotic that is highly resistant to beta-lactamase degradation. It was under development for the treatment of acute bacterial sinusitis, community-acquired pneumonia, acute exacerbation of chronic bronchitis, and uncomplicated skin and skin structure infections.

Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid. Ascorbic acid is transported in its oxidized form via GLUT1 across the blood-brain barrier. Dehydroascorbic acid delay low-density lipoprotein (LDL) oxidation when added before the initiation of the process, they accelerate the process if added to minimally oxidized LDL. Dehydroascorbic acid is used as biochemical markers of oxidative stress in clinical investigations. Dehydroascorbic acid has been used as a vitamin C dietary supplement.
