Aftobetin, also known as ANCA11 and NCE-11, is a novel amyloid–binding compound applied topically in the form of an ophthalmic ointment. Aftobetin offers a promising way for a noninvasive eye-scan to diagnose Alzheimer’s disease early.

Ritobegron (KUC 7483) is a selective β3-adrenoceptor agonist that was developed for oral treatment of overactive bladder. It is the prodrug of the active compound KUC-7322. Phase I studies have investigated the pharmacodynamic and pharmacokinetic effects of ritobegron in healthy individuals and patients with spinal cord injury. Ritobegron exhibits a high selectivity for the bladder versus other organs, and decreased intravesical pressure with minimal effects on the cardiovascular system in rats. When administered in combination with organic anion transporter (OAT) inhibitors such as probenecid (primarily used in treating gout and hyperuricemia), the plasma concentration of the active compound KUC-7322 may increase.

Zamicastat (also known as BIA 5-1058) is a dopamine β-hydroxylase (DβH) inhibitor that decreases noradrenaline and increases dopamine levels in peripheral sympathetically innervated tissues. It is known that the use of DβH inhibitors is a promising approach to treat hypertension, heart failure and cardiovascular diseases where a reduction in the sympathetic tone has beneficial effects. Zamicastat participated in phase II clinical trials in pulmonary arterial hypertension as adjuvant therapy in Austria. In addition, the drug successfully completed phase I in patients with hypertension and chronic heart failure.

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produced immediate side effects such as hepatotoxicity and gastrointestinal disturbances, and was consequently withdrawn.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.

Naquotinib (ASP8273) is an orally available, irreversible, mutant-selective, epidermal growth factor receptor (EGFR) inhibitor, with potential antineoplastic activity. Naquotinib was found by mass spectrometry to covalently bind to a mutant EGFR (L858R/ T790M) via cysteine residue 797 in the kinase domain of EGFR with long-lasting inhibition of EGFR phosphorylation for 24 h. In the NSCLC cell lines harboring the above EGFR mutations, Naquotinib had IC50 values of 8-33 nM toward EGFR mutants, more potently than that of WT EGFR (IC50 value of 230 nM). In mouse xenograft models, Naquotinib induced complete regression of the tumors after 14 days of treatment. ASP8273 even showed activity in mutant EGFR cell line which is resistant to other EGFR TKIs. Naquotinib is in phase III clinical trials for the oral treatment of EGFR mutated non-small cell lung cancer (NSCLC).

PSI-352938 is a nucleoside derivative patented by Pharmasset, Inc. as an antiviral agent. PSI-352938 acts as a novel cyclic phosphate prodrug of β-D-2'-deoxy-2'-α-fluoro-2'-β-C-methylguanosine-5'-monophosphate with potent anti-HCV activity. PSI-352938 inhibits HCV genotype (GT) 1b replicon replication with 50% effective concentrations (EC50s) of 0.13 ± 0.076 μM, and active against GT 1a and 2a replicons and infectious viruses PSI-352938 retained full activity against replicons containing the S282T substitution, which confers resistance to certain 2'-substituted nucleoside/nucleotide analogs. In April 2013, because of hepatic toxicity, Gilead Sciences discontinued the development of PSI-352938.

Caloxetate Trisodium is triazaundecanedioic acid derivative patented by German pharmaceutical company as liver-specific magnetic resonance imaging contrast agent.

Truxipicurium, a derivative of alpha-truxillic acid, a curare-like drug, is a neuromuscular blocking agent with rigid structure.

Levisoprenaline (l-isoproterenol) is beta1- and beta2-adrenoreceptor agonist. In Japan, continuous inhalation of levisoprenaline is a recommended treatment for pediatric patients with acute severe exacerbation. Compared with salbutamol, l-isoproterenol reduced modified pulmonary index score more rapidly. But in most countries do not recommend continuous inhalation of l-isoproterenol to treat pediatric patients with acute severe exacerbation of asthma due to worsening asthma control. Levisoprenaline was used to cause experimental chronic heart failure in rats.
