Pfizer was developing PF-3882845, an orally available nonsteroidal antagonist of the mineralocorticoid receptor, for the treatment of diabetic nephropathies. PF‐03882845 is a highly potent (IC50 = 6.3‐13.4 nM, 10% fetal bovine serum & IC50 = 0.504–1.11 nM, absence of serum) selective orally bioavailable mineralocorticoid receptor antagonist. It is a non‐steroidal pyrazoline, unlike steroidal compounds eplerenone and spironolactone. It does not significantly activate or inhibit human androgen receptor, estrogen receptor alpha, and glucocorticoid receptor. PF‐03882845 has been shown to modestly inhibit the progesterone receptor (PR) yielding a 45‐fold selectivity over PR in a cell‐based functional assay. PF‐03882845 was previously in development for the treatment of diabetic nephropathy — development for this indication was terminated for strategic reasons. An alternative indication of hypertension also was not pursued for strategic reasons.

Emilium is an antiarrhythmic agent and cardiac depressant.

Galeterone (TOK-001, formerly called VN/124-1) is a potent anti-androgen with three modes of action. The compound acts as a specific androgen receptor antagonist, inhibits CYP17 lyase while conserving CYP17 hydroxylase function, and decreases overall androgen receptor levels in prostate cancer cells. Galeterone is a first in class, multi-targeted small-molecule drug that disrupts the growth and survival of prostate cancer cells. Tokai Pharmaceuticals is developing galeterone as an oral treatment for castration-resistant prostate cancer. Phase III clinical development of galeterone is underway in the US, Canada, Australia, Western Europe, Spain and the United Kingdom.

Benfosformin (also known as JAV 852), a phosphorylated biguanide that was studied as a hypoglycemic and antidiabetic agent. However, the information about the studies of this compound now is not available.

Cerdulatinib is an oral, dual spleen tyrosine kinase (Syk) and janus kinase (JAK) inhibitor that uniquely inhibits two key cell signaling pathways that promote cancer cell growth in certain hematologic malignancies – the B-cell receptor pathway via Syk and key cytokine receptors via JAK Being developed to treat patients with hematologic cancers, specifically those who have relapsed or who have not responded to prior therapies. Cerdulatinib is in Phase 2 study evaluating the safety and efficacy of cerdulatinib in patients with relapsed/refractory B-cell malignancies who have failed multiple therapies.

Viquidacin (also known as NXL-101), a quinoline antibacterial agent, was studied as a bacterial DNA gyrase and topoisomerase IV inhibitor. Viquidacin showed potent activity against gram-positive bacteria, including methicillin- and fluoroquinolone-resistant strains. The drug participated in phase I clinical trial. Viquidacin achieved homogeneous and potent bactericidal concentrations in human volunteer plasma. However, further, development was discontinued after QT interval prolongation, which was observed in a healthy volunteer.
