Fipexide (Attentil, Vigilor), a psychoactive drug of the piperazine chemical class, was developed in Italy in 1983. It was served as a nootropic drug in France and Italy, mainly for the therapy of senile dementia, but is no longer in common use because of the occurrence of rare drug side-effects including hepatitis and fever.

Nateglinide (Senaglinide) is an oral hypoglycemic agent and amino acid derivative that stimulates insulin secretion from the pancreas and is used in the therapy of type 2 diabetes. Nateglinide has been linked to rare instances of clinically apparent acute liver injury.

Montelukast sodium (MK0476) is an orally available leukotriene receptor antagonist which is widely used for the prophylaxis and chronic treatment of asthma and has been linked to rare cases of clinically apparent liver injury.

Levobupivacaine is an amino-amide local anaesthetic drug belonging to the family of n-alkylsubstituted pipecoloxylidide. It is the S-enantiomer of bupivacaine. Levobupivacaine hydrochloride is commonly marketed by AstraZeneca under the trade name Chirocaine. Compared to bupivacaine, levobupivacaine is associated with less vasodilation and has a longer duration of action. It is approximately 13 per cent less potent (by molarity) than racemic bupivacaine.Levobupivacaine is indicated for local anaesthesia including infiltration, nerve block, ophthalmic, epidural and intrathecal anaesthesia in adults; and infiltration analgesia in children. Adverse drug reactions (ADRs) are rare when it is administered correctly. Most ADRs relate to administration technique (resulting in systemic exposure) or pharmacological effects of anesthesia, however allergic reactions can rarely occur.

Tributyl phosphate (NSC 8484, Tributyl phosphate) is a trialkyl phosphate that is often used as a solvent, plasticizer, and extractant, including in extraction processes involving transuranic elements and rare earth metals.

Inosine pranobex (Delimmun) has a number of immunomodulatory effects, including inducing T-lymphocyte differentiation, augmenting macrophage and NK cell functions, and stimulating IL-2 production. Through these effects and others, isoprinosine shows antiviral activity and has applications against subacute sclerosing panencephalitis. It also restores depressed immune responses in Y patients after irradiation and reduces the incidence of infection in leukemia patients undergoing chemotherapy. It is most commonly used to treat the rare measles complication subacute sclerosing panencephalitis in conjunction with intrathecal interferon therapy.

Myristic acid (Crodacid) , a 14 carbon saturated fatty acid, is a rare molecule in cells and is a substrate of some fatty acid desaturases. This compound has the ability to acylate proteins by covalently binding to the N-terminal glycine residues, in a process called N-terminal myristoylation. Myristoylation of substrate proteins by this fatty acid has the potential to activate and mediate many physiological pathways. Furthermore, saturated fatty acids have been reported to be essential for biological activities of lipopolysaccharides and have demonstrated the ability to induce expression of COX-2 and NFκB (nuclear factor κB) activation.

L-Leucine ((S)-Leucine) is one of nine essential amino acids in humans (provided by food), L-Leucine is important for protein synthesis and many metabolic functions. L-Leucine contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. L-Leucine also prevents breakdown of muscle proteins after trauma or severe stress and may be beneficial for individuals with phenylketonuria. L-Leucine is available in many foods and deficiency is rare.

Amifampridine (3,4-Diaminopyridine) is primarily used to treat rare muscle diseases. It blocks potassium channel efflux in nerve terminals, increasing action potential duration, which allows Ca2+ channels to remain open longer and enhances acetylcholine release to stimulate muscles at the end plate.

D-Tagatose (D-(-)-Tagatose), a rare natural hexoketose and isomer of D-galactose, occurs naturally in Sterculia setigera gum and is found in small quantities in various foods such as sterilized and powdered cow's milk, hot cocoa, and various cheeses, yogurts, and other dairy products. It can be synthesized from D-galactose by isomerization under alkaline conditions in the presence of calcium. D-Tagatose has numerous health benefits, including promotion of weight loss, no glycemic effect, anti-plaque, non-cariogenic, anti-halitosis, prebiotic, and anti-biofilm properties; it is beneficial for organ transplants, enhancement of flavor, improvement of pregnancy and fetal development, treatment of obesity, and reduction in symptoms associated with type 2 diabetes, hyperglycemia, anemia, and hemophilia.

2-Methylsuccinic acid (Pyrotartaric Acid) is a normal metabolite found in human fluids. Increased urinary levels of 2-Methylsuccinic acid (Pyrotartaric Acid) (together with ethylmalonic acid) are the main biochemical measurable features in ethylmalonic encephalopathy, a rare metabolic disorder with an autosomal recessive mode of inheritance that is clinically characterized by neuromotor delay, hyperlactic acidemia, recurrent petechiae, orthostatic acrocyanosis, and chronic diarrhea.

Carglumic Acid (Ureidoglutaric acid) is an orphan drug used to treat hyperammonemia in patients with N-acetyl glutamate synthase absence. This rare hereditary disease results in elevated blood levels of ammonia, which can eventually cross the blood-brain barrier and lead to neurologic problems, coma, cerebral edema, and death. Carglumic acid was approved by the U.S. FDA on 18 March 2010.

Methyl 3-O-methylgallate (M3OMG) is a rare natural product with promising antioxidant activities.
