Perifosine is an orally active alkyl-phosphocholine compound with potential antineoplastic activity. Perifosine is an Akt inhibitor, which targets the pleckstrin homology domain of Akt, thereby preventing its translocation to the plasma membrane. Perifosine exerts Akt-dependent and Akt-independent effects, and although many preclinical studies have documented Akt inhibition by perifosine, clinical validation of these findings is lacking. Perifosine is in phase II and III clinical trials for the treatment of neuroblastoma, glioblastoma multiforme and other solid tumors.

Dexamethasone beloxil is anti-inflammatory used in the treatment of uveitis, iritis, keratitis, postsurgical inflammation, vernal keratoconjunctivitis, and giant papillary conjunctivitis.

Eritoran (E-5564) is a synthetic lipid A analog that has been designed to antagonize the effects of lipopolysaccharide (LPS) and has been found to do this by interacting with Toll-like receptor 4, the cell surface receptor for LPS. Preclinical in vitro and in vivo studies of eritoran tetrasodium indicate it can limit excessive inflammatory mediator release associated with LPS and improve survival in sepsis models. Clinically, eritoran was being investigated for the treatment of severe sepsis, septic shock, and other endotoxin-mediated indications. Eritoran development has been discontinued.

Edelfosine is a synthetic alkyl-lysophospholipid, a potent immunomodulator and an effective inhibitor of tumor cell proliferation. The cytotoxic effect of edelfosine has been evaluated in a large variety of both tumor (leukemic and solid) and normal cell types, showing a high degree of selectivity towards tumor cells. Like all alkyl-lysophospholipids, Edelfosine incorporates into the cell membrane and does not target the DNA. In many tumor cells, Edelfosine causes selective apoptosis, sparing healthy cells. Edelfosine can activate the Fas/CD95cell death receptor, can inhibit the MAPK/ERK mitogenic pathway and the Akt/protein kinase B (PKB) survival pathway. Edelfosine apoptosis-inducing abilities were studied with several types of cancer, among them multiple myeloma and non-small and small cell lung carcinoma cell lines. In vivo activity against human solid tumors in mice was shown against malignant gynecological tumor cells, like ovarian cancer, and against breast cancer. In vivo biodistribution studies demonstrated a “considerably higher” accumulation of Edelfosine in tumor cells than in other analyzed organs. Several clinical trials were conducted. Among them, a phase I trials with solid tumors or leukemias and phase II with non-small-cell lung carcinomas (NSCLC). In Phase II clinical trial for use of Edelfosine in treating leukemia with bone marrow transplants, it was found to be safe and 'possibly effective'. A phase II trial for the treatment of brain cancers was also reported. It showed encouraging results in stopping the growth of the tumor and a considerable improvement in the “quality of life” of the patients. A phase II trial on the effect of Edelfosine on advanced non-small-cell bronchogenic carcinoma had a “remarkable” “high proportion of patients with stationary tumor status” as result, stable disease after initial progression in 50% of the patients.

Metronidazole phosphate is a water-soluble prodrug of metronidazole.

Triamcinolone acetonide- 21-dihydrogen phosphate is the long-acting derivative of a synthetic glucocorticoid triamcinolone. Triamcinolone acetonide has eight times more potency than prednisolone. Triamcinolone acetonide- 21-dihydrogen phosphate used for intravenous injection. It is supposed to be hydrolyzed rapidly in the body to form the free corticoid alcohol.

SR 202 is an antagonist of peroxisome proliferator-activated receptor γ (PPARγ) transcriptional activity induced by troglitazone but not of basal PPARγ activity. It is selective for PPARγ, not affecting basal or agonist-induced transcriptional activity of PPARα, PPARβ, or the farnesoid X receptor (FXR). It inhibits PPARγ-dependent differentiation of preadipocyte 3T3-L1 cells in a dose-dependent manner. SR 202 (400 mg/kg) decreases the amount of weight gained and white adipose tissue mass accumulated by mice fed a standard or high-fat diet for ten weeks and is associated with lower PPARγ mRNA levels. It protects against high-fat diet-induced insulin resistance in wild-type mice and improves insulin sensitivity in ob/ob mice.
