Protizinic acid is an elaborated member of propionic acid series, and is a cyclooxygenase inhibitor with antiinflammatory and antipyretic activity

Ranelic acid is an organic acid capable of chelating metal cations. Ranelic acid is an organic, highly polar molecule without pharmacological activity, its salt form, s, is a drug used to treat osteoporosis and increase bone mineral density

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.

ISOSPAGLUMIC ACID is used as an antiallergic agent.

Ufenamate is a topical analgesic. It is indicated for pain and inflammation associated with musculoskeletal and joint disorders. It is a COX inhibitor. Ufenamate is freely soluble in oil and is poorly soluble in water. It is used in the form of ointments or creams. It is manufactured under the brand name Combec in Japan. It is also an ingredient of Fenazol Ointment 5%, used in Japan for the treatment of eczema, dermatitis and herpes zoster.

There is no information related to the biological and pharmacological properties of the aleuritic acid. But is known, that this compound is is the major acid constituent of the lac resin secreted by Indian lac insect Kerria lacca. Also, it can be obtained from shellac by saponification. Aleuritic acid is a unique acid containing three hydroxyl groups of which two are of adjacent carbon atoms. It is used as a component in the perfume industry for the preparation of musk aroma.

Sultosilic acid is a benzenesulfonate ester. Sultosilic acid has been shown to be a hypolipidaemic drug both in animal experiments and in human clinical studies, chemically unrelated to other such drugs. The compound is being developed as a human drug (Mimedran ®) and is formulated as the piperazine salt (A-585). The recommended daily dose is three times one tablet containing 500 mg of Sultosilic acid.

Xenyhexenic acid is a biphenyl organic compound, discovered in 1958. When fed to rats, xenyhexenic acid inhibited hypercholesterolemia and hyperlipemia that been induced by the administration of Triton.

Morniflumate is a non-steroidal anti-inflammatory drug and represent as a beta-morpholinoethyl ester of niflumic acid, which is rapidly hydrolyzed in the plasma, releasing the free acidic form, the molecule responsible for the pharmacological effects. It was shown, that morniflumate was effective in the treatment of chronic recurring bronchitis and inhibited cyclooxygenase-1, 2 (COX-1, 2). Morniflumate has a 30-year history of clinical use, particularly for the treatment of pain associated with pediatric ear-nose-throat (ENT) infection. In addition, it appears to be a valid and well-tolerated alternative to other NSAIDs, or to antibiotics, for the treatment of pain and other symptoms of soft tissue inflammation.

Acefylline is a stimulant drug of the xanthine chemical class. It acts as an adenosine receptor antagonist. Acephylline piperazine is a theophylline derivative with a direct bronchodilator action. It has the advantages over theophylline in being far less toxic and producing minimal gastric irritation. It is indicated for the treatment of asthma, emphysema, acute and chronic bronchitis associated with bronchospasm.Acefylline relaxes smooth muscles, relieves bronchospasm & has a stimulant effect on respiration. It stimulates the myocardium & central nervous system, decreases peripheral resistance & venous pressure & causes diuresis. The mechanism of action is still not clear, inhibition of phosphodiesterase with a resulting increase in intracellular cyclic AMP does occur, but not apparently at concentrations normally used for clinical effect. Other proposed mechanisms of action include adenosine receptor antagonism, prostaglandin antagonism & effects on intracellular calcium. Sodium phenobarbital is a non-selective central nervous system depressant that is primarily used as sedative-hypnotic.
