Mephenytoin is an antiepileptic drug which can be useful in the treatment of epilepsy. The primary site of action appears to be the motor cortex where spread of seizure activity is inhibited. Possibly by promoting sodium efflux from neurons, mephenytoin tends to stabilize the threshold against hyperexcitability caused by excessive stimulation or environmental changes capable of reducing membrane sodium gradient. This includes the reduction of posttetanic potentiation at synapses. Loss of posttetanic potentiation prevents cortical seizure foci from detonating adjacent cortical areas. Mephenytoin reduces the maximal activity of brain stem centers responsible for the tonic phase of tonic-clonic (grand mal) seizures. The mechanism of action of mephenytoin is not definitely known, but extensive research strongly suggests that its main mechanism is to block frequency-, use- and voltage-dependent neuronal sodium channels, and therefore limit repetitive firing of action potentials. Mephenytoin is no longer available in the US or the UK. It is still studied largely because of its interesting hydroxylation polymorphism.

AMINOBENZOATE SODIUM is a salt of Aminobenzoic acid. Aminobenzoic acid is an intermediate in the synthesis of folate by bacteria, plants, and fungi. Many bacteria, including those found in the human intestinal tract such as E. coli, generate Aminobenzoic acid from chorismate by the combined action of the enzymes 4-amino-4-deoxychorismate synthase and 4-amino-4-deoxychorismate lyase. Plants produce Aminobenzoic acid in their chloroplasts, and store it as a glucose ester (pABA-Glc) in their tissues. Humans lack the enzymes to convert Aminobenzoic acid to folate, so require folate from dietary sources such as green leafy vegetables. In humans, Aminobenzoic acid is considered nonessential and, although it has been referred to historically as "vitamin Bx", is no longer recognized as a vitamin, because most people have colon bacteria that generate Aminobenzoic acid. The potassium salt is used as a drug against fibrotic skin disorders, such as Peyronie's disease, under the trade name Potaba.

Hexylresorcinol is an organic compound with local anaesthetic, antiseptic and anthelmintic properties. It is available for use topically on small skin infections, or as an ingredient in throat lozenges. Hexylresorcinol may be used as a cosmetic biocide. Hexylresorcinol was introduced by Leonard as a urinary antiseptic with great possibilities. Used in alkaline solution it promised success in experiments in vitro. Boots Hexylresorcinol 2.4mg Throat Lozenges, marketed in UK, are used to relieve sore throat pain. Hexylresorcinol has being shown to be useful for the topical treatment of hyperpigmentation.

Vanillin (4-hydroxy-3-methoxybenzaldehyde), a pleasant smelling organic aromatic compound, is widely used as a flavoring additive in food, beverage, cosmetic and drug industries. It is reported to cross the blood brain barrier and also displayed antioxidant and neuroprotective activities. Vanillin is a natural substance widely found in many plant species and often used in beverages, foods, cosmetics, and pharmaceutical products. Antioxidant and anticancer potential have been described for this compound. Vanillin has been classified as
a bioantimutagen and is able to inhibit mutagenesis induced
by chemical and physical mutagens in various cell systems. Vanillin, a selective agonist of TRPV1, has been shown to attenuate i.c.v. STZ and AlCl3+d-galactose induced experimental Alzheime's disease (AD).

Acetone (or propanone) is the smallest and simplest ketone, which is used in cosmetic as a nail polish remover. Acetone is produced within the body because of the breakdown of stored fats and lipids as a source of energy. Such conditions as physical exercise and prolonged dieting, which lead to cleavage of fat within the body, may result in higher than average amounts of acetone in the bloodstream. The concentration of acetone in the environment doesn’t cause a neurotoxic, carcinogenic, or reproductive health hazard effect. In addition, experiments on rodents have shown that acetone possesses anticonvulsant properties.

Conditions:
Procaine is an anesthetic agent indicated for production of local or regional anesthesia, particularly for oral surgery. Procaine (like cocaine) has the advantage of constricting blood vessels which reduces bleeding, unlike other local anesthetics like lidocaine. Procaine is an ester anesthetic. It is metabolized in the plasma by the enzyme pseudocholinesterase through hydrolysis into para-aminobenzoic acid (PABA), which is then excreted by the kidneys into the urine. Procaine acts mainly by inhibiting sodium influx through voltage gated sodium channels in the neuronal cell membrane of peripheral nerves. When the influx of sodium is interrupted, an action potential cannot arise and signal conduction is thus inhibited. The receptor site is thought to be located at the cytoplasmic (inner) portion of the sodium channel. Procaine has also been shown to bind or antagonize the function of N-methyl-D-aspartate (NMDA) receptors as well as nicotinic acetylcholine receptors and the serotonin receptor-ion channel complex.

Phenoxyacetic acid is found in cocoa and cocoa products. Phenoxyacetic acid is a flavouring ingredient. Phenoxyacetic acid is on the FDA list of approved food additives (PART 172 - FOOD ADDITIVES PERMITTED FOR DIRECT ADDITION TO FOOD FOR HUMAN CONSUMPTION; Subpart F--Flavoring Agents and Related Substances Sec. 172.515 Synthetic flavoring substances and adjuvants.). Research has shown that Phenoxyacetic acid induced hematopoietic cell proliferation, providing potential for oral therapeutics which stimulate proliferation of hematopoietic cells of multiple lineages, as well as inducing fetal globin, important for therapy of hemoglobinopathies.
