(R)-Sulindac is the (R)-enantiomer of nonsteroidal anti-inflammatory drug (NSAID) Sulindac, that is marketed in the U.S. by Merck as Clinoril. Sulindac is a prodrug, derived from sulfinylindene, that is converted in vivo to an active sulfide compound by liver methionine sulfoxide reductases (Msr). The (Msr) family of enzymes includes two major classes, MsrA and MsrB, that specifically reduce the S- and R-epimers of Sulindac. Reduction of (R)-Sulindac to Sulindac Sulfide catalyzed by methionine sulfoxide reductase (Msr)-B. The oxidation of both epimers to sulindac sulfone is catalyzed primarily by the microsomal cytochrome P450 (P450) system. (S)-Sulindac increases the activity of the P450 system better than (R)-sulindac, but both epimers increase primarily the enzymes that oxidize (R)-sulindac. Both epimers can protect normal lung cells against oxidative damage and enhance the killing of lung cancer cells exposed to oxidative stress.

Sulfamazone is a long-acting sulfonamide antibiotic with antipyretic properties. It is not approved by the FDA, but is marketed in Italy under tradename Marespin for the treatment of acute respiratory diseases; primary bacterial pharyngotonsillitis and tracheobronchitis or complications of the flu or other viral diseases of the upper respiratory tract.

Spaglumic acid (NAAG) is the β-aspartyl isoform of N-Acetyl-l-aspartylglutamate (isospaglumic Acid is N-(N-Acetyl-l-α-aspartyl)-l-glutamic acid). In eye drops, spaglumic acid is either a magnesium or sodium salt of N-Acetyl-l-aspartylglutamate. Spaglumic acid is a mast cell stabilizer. Thus it is used in allergic conditions such as allergic conjunctivitis. Specifically spaglumic acid is approved in Portugal under the brand name Naabak and in Greece under the brand name Naaxia for use in patients with allergic conjunctivitis. Spaglumic Acid is a peptide neurotransmitter and the third-most-prevalent neurotransmitter in the mammalian nervous system. It is a weak activator of NMDA receptors and a highly selective agonist for mGlu3 receptors. Spaglumic Acid is neuroprotective under non-hydrolysing conditions in vivo.

Watanidipine (AE0047) had been NDA filed for the treatment of hypertension in Japan. Watanidipine (as Calbren®) was awaiting registration with Mitsubishi Pharma Corporation in Japan. However, Mitsubishi Pharma Corporation has discontinued the development of this drug. Watanidipine had also been in phase II clinical trials for the treatment of stroke and preclinical trials for atherosclerosis. However, no recent development has been reported. Watanidipine (AE0047) has being shown to be a calcium antagonist with protective effects against cerebral ischaemia and the occurrence of stroke in several animal models.

Phenibut (beta-phenyl-gamma-aminobutyric acid or 4-amino-3-phenylbutyric acid) is a neuropsychotropic drug that was discovered and introduced into clinical practice in Russia in the 1960s. It has anxiolytic and nootropic (cognition enhancing) effects. It acts as a GABA-mimetic, primarily at GABA(B) receptors. Pharmacological activity of racemic phenibut relies on R-phenibut and this correlates to the binding affinity of enantiomers of phenibut to the GABAB receptor. In addition R-phenibut binds to the α2-δ subunit of voltage-dependent calcium channels. It is highly effective in treating anxiety, post-traumatic stress disorder, depression, asthenia, insomnia, alcoholism, stuttering, and vestibular disorders. It also improves mental performance (attention, memory, speed and accuracy of sensory-motor reactions), physical performance, reduces sleep disorders as well as movement and speech disorders.

Laninamivir ocatanoate is a prodrug of Laninamivir (R-125489), a new neuraminidase (NA) inhibitor, was discovered, and in this study, its NA inhibitory activities against various influenza viruses including oseltamivir-resistant viruses are reported. Laninamivir octanoate has been approved for use in Japanese clinics for the treatment and prevention of influenza in both adults and children. The inhaled laninamivir octanoate is converted into its active form, laninamivir, in the lungs where a high concentration persists for a long period of time.

THALLOUS OXIDE (Thallium (1) Oxide) has been used in the manufacturing of glass of a high coefficient of refraction for optical purposes (thallium flint glass) and for artificial gems. Thallium oxide is black in color and is the inorganic compound of Thallium and Oxygen. THALLOUS OXIDE compounds are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics (e.g. tablets) and in light weight structural components in aerospace and electrochemical applications such as fuel cells. THALLOUS OXIDE is toxic by ingestion. It has previously been used as rat poison and ant killer, but its use is prohibited since 1972.

Nicergoline is a semisynthetic ergoline derivative that has been used as a cerebral vasodilator and in peripheral vascular disease. Nicergoline seems to have an action: (i) as an alpha1-adrenoceptor antagonist, it induces vasodilation and increases arterial blood flow; (ii) it enhances cholinergic and catecholaminergic neurotransmitter function; (iii) it inhibits platelet aggregation; (iv) it promotes metabolic activity, resulting in increased utilization of oxygen and glucose; and (v) it has neurotrophic and antioxidant properties. Nicergoline has been suggested to ameliorate cognitive deficits in cerebrovascular disease.
