Esoxybutynin is (S)-enantiomer of oxybutynin. Esoxybutynin exerts antimuscarinic properties. Racemic oxybutynin is used clinically to treat urinary incontinence. Sepracor was developing (S)-oxybutynin, a single-isomer version of Alza's Ditropan (racemic oxybutynin), a muscarinic acetylcholine receptor antagonist, as a potential treatment for urinary incontinence.

Lorediplon is a novel non-benzodiazepine, the hypnotic drug acting as a GABAA receptor modulator, differentially active at the alpha1-subunit, associated with promoting sleep. As compared with other selective benzodiazepine receptor agonists, lorediplon has demonstrated in pre-clinical studies a potent hypnotic profile with potential advantages in sleep maintenance and sleep architecture preservation associated with a good safety profile, that is, no induction of tolerance, lack of next-day hangover effect, weak effect on muscular tone, and weak interaction with ethanol. Lorediplon demonstrated a minimum of 10-fold and the 6-fold increase in potency (respectively) in the spontaneous motor activation studies, compared with the currently marketed hypnotics (zolpidem and zaleplon). Additionally, when the electroencephalogram (EEG) effects of lorediplon and zolpidem were compared in the sleep-wake cycle in the mouse, lorediplon demonstrated a 10-fold increase in potency compared with zolpidem in the sleep-wake cycle and 13% greater possibility of fewer wake episodes than zolpidem. At concentrations of 1.2mg/kg, lorediplon demonstrated a 57%increased effect on Slow Wave Sleep (SWS), when compared with a placebo. In clinical trials, the clinical safety and tolerability were excellent for all doses tested. In pharmacokinetic studies, after oral administration, lorediplon is rapidly absorbed from the gastrointestinal tract reaching maximum plasma concentrations at approximately 2 h. Lorediplon demonstrated a dose-dependent improvement in sleep, whereas zolpidem showed a more sustained wake after sleep onset effect. No next-day hangover effects were observed. These sleep effects are also consistent with the pharmacokinetic profile of lorediplon.

Besifovir (also known as LB80331), an active metabolite of LB80380 was studied for the treatment of hepatitis B.

Pyrazoloacridine is a pyrazolo[3,4,5-kl]acridine derivative patented by Warner-Lambert Co. as an anticancer agent. Pyrazoloacridine acts as topoisomerase I and II inhibitor that decrease the formation of topoisomerase-DNA adducts. In vitro experiments, Pyrazoloacridine shows efficacy against multidrug-resistant neuroblastoma doxorubicin-resistant human colon carcinoma and breast cancer cell lines. In clinical trials, Pyrazoloacridine demonstrates moderate efficacy in metastatic breast cancer and a high level of adverse events. The dose-limiting toxicity was grade 4 neutropenia. Other grade 3 and 4 toxicities include vomiting, nausea, neurotoxicity, fatigue, and anemia.

Glyceryl trierucate (trierucin) is a trierucic acid triglyceride that has been investigated for the treatment of adrenoleukodystrophy, a rare genetic disorder characterized by the breakdown or loss of myelin in the brain. To investigate treatment options for adrenoleukodystrophy, most studies have used “Lorenzo's oil" (LO), a 4:1 mixture of glyceryl trioleate and glyceryltrierucate. Lorenzo’s oil was found to reduce the levels of saturated very long chain fatty acids (ELOVL) in the plasma, adipose tissue and liver, but to a lesser extent in the brain. Inhibition of ELOVL 1 may be an underlying mechanism by which Lorenzo's oil exerts its action. Several clinical trials have been conducted to study the potential of glyceryl trierucate in treatment of adrenoleukodystrophy.

AZD1305, an antiarrhythmic agent, blocks the hERG potassium channel, the L-type calcium, and the Sodium channel protein Nav1.5. AZD1305 participated in clinical trials for the management of atrial fibrillation and Left ventricular dysfunction. The benefit-risk profile was judged as unfavorable and the AZD1305 development programme was discontinued.

Telapristone is an orally available 21-substituted-19-nor-progestin and selective progesterone receptor modulator (SPRM), with potential anti-progesterone and antineoplastic activities. Its acetate form, the telapristone Acetate is a clinically used and a studied drug.

Oxi0-4503 (now known as combretastatin A1 phosphate), a diphosphate prodrug of combretastatin A1, was developed by Mateon therapeutics as a second-generation, dual-mechanism vascular disrupting agent from the combretastatin family. On November 21, 2012, Oxi-4503 has been granted orphan designation by the US Food and Drug Administration for the treatment of acute myelogenous leukemia. It is known that the orphan drug designation qualifies a company for several benefits, including the potential for market exclusivity, development grants, and tax credits. Oxi0-4503 is currently participating in phase I/II clinical trial the treatment of patients with acute myelogenous leukemia or myelodysplastic syndrome. In addition, phase I clinical trial was successfully completed where was studied the safety of Oxi0-4503 in patients with advanced solid tumors.
