Aceneuramic acid (also known as N-Acetylneuraminic Acid, Neu5Ac, the UX 001 tablets) prolonged released had been filed a marketing authorization application with the European Medicines Agency by Ultragenyx in the EU for the treatment of hereditary inclusion body myopathy (HIBM), a rare, progressive muscle-wasting disease. This compound, a muscle protein stimulant, is also in phase II of the clinical trial for the treatment thrombocytopenia. In addition, recently was made studies, which had shown, that existed the significant positive correlation between serum and salivary sialic acid levels in oral squamous cell carcinoma (OSCC) patients.

Rosmarinic acid (α-o-caffeoyl-3,4-dihydroxyphenyllactic acid; RA) is a naturally occurring hydroxylated compound commonly found in species of the subfamily Nepetoideae of the Lamiaceae and Boraginaceae, such as Rosmarinus officinalis, Salvia officinalis, and Perilla frutescens. RA is biosynthesized from the amino acids L-phenylalanine and L-tyrosine by eight enzymes that include phenylalanine ammonia lyase and cinnamic acid 4-hydroxylase. Recently, RA and its derivatives have attracted interest for their biological activities, which include anti-inflammatory, anti-oxidant, anti-angiogenic, anti-tumor, and anti-microbial functions. Clinically, RA attenuates T cell receptor-mediated signaling, attenuates allergic diseases like allergic rhinitis and asthma, and 2,4-dinitrofluorobenzene-induced atopic dermatitis-like symptoms, protects from neurotoxicity, and slows the development of Alzheimer's disease. Rosmarinic Acid seems to be able to suppress 5-lipoxygenase and 5-HETE synthesis (a pro-inflammatory compound in the omega-6 metabolic chain). Rosmarinic acid appeared to be effective in suppressing allergies in a dose-dependent manner, with 30% of the placebo group reporting symptom relief compared to 55.6% of the 50mg group and 70% of the 200mg group.

Fulvic acid is primarily studied for its effects on plants and soil. Fulvic acid is an organic and natural electrolyte. Depending on the situation, Fulvic acid can act as an electron donor or acceptor and an oxidizer or reducer. Fulvic acid has exhibited the ability to enhance the availability and adsorption of nutrients as well as prolong their time of residence. In the chick animal model Fulvic acid disturbed the processing of procollagen II in articular cartilage. Fulvic acid has being shown to attenuate homocysteine-induced cyclooxygenase-2 expression in human monocytes. Fulvic acid, the main active principle of Shilajit (a natural substance found mainly in the Himalayas), blocks tau self-aggregation, opening an avenue toward the study of Alzheimer's therapy. People take fulvic acid by mouth for brain disorders such as Alzheimer’s disease, as well as respiratory tract infections, cancer, fatigue, heavy metal toxicity, and preventing a condition in which the body tissues do not receive enough oxygen (hypoxia).

Butyric acid (butanoic acid) belongs to a group of short-chain fatty acids and is thought to play several beneficial roles in the gastrointestinal tract. The butyric anion is easily absorbed by enteric cells and used as a main source of energy. Moreover, butyric acid is an important regulator of colonocyte proliferation and apoptosis, gastrointestinal tract motility and bacterial microflora composition in addition to its involvement in many other processes including immunoregulation and anti-inflammatory activity. Butyric acid shows a protective effect in inflammatory response secondary to inflammatory bowel diseases. A beneficial effect of butyric acid as one constituent of a multifaceted mechanism modulating gastrointestinal function has also been stressed in patients with the stoma and coexisting constipation. Butyric acid supplementation combined with the use of probiotics should be adopted as one of the basic therapeutic strategies in this patient group, preceding treatment with laxatives. Sodium butyrate in the form of enemas (combined in a mixture with A-300 silicon dioxide) may be a successful method of therapeutic management in patients with radiation proctitis. Sodium butyrate may also prevent diarrhea through an increased passive absorption of water in the colon and its effects on the gut microflora.

Aminomethylbenzoic acid (or p-aminomethylbenzoic acid, or PAMBA) an antifibrinolytic agent. This drug has been used for the treatment of internal hemorrhage during chronic disseminated intravascular coagulation.

Beta-alanine is an endogenous agonist of glycine receptor, which is used a supplementation among competitive athletes participating in a range of different sports. Beta-alanine has been shown to enhance muscular endurance and its supplementation appears to be most effective for exercise tasks that rely heavily on ATP synthesis from anaerobic glycolysis.

Retinal, All-trans is one of the forms of vitamin A. It is an isomer of 11-cis-retinal, transductor of light into the neural signals. Retinal, All-trans is converted to retinoic acid in vivo by the action of retinal dehydrogenase. Retinal, All-trans is associated with one of the two isoforms of cellular retinol-binding proteins (CRBP-I and CRBP-II). These proteins play important roles in retinoid biology and regulation of the metabolism of retinol and retinal.

Orotic acid is a minor dietary constituent. Historically it was believed to be part of the vitamin B complex and was called vitamin B13, but it is now known that it is not a vitamin and is synthesized in the body, where it arises as an intermediate in the pathway for the synthesis of pyrimidine nucleotides. Orotic acid is converted to UMP by UMP synthase, a multifunctional protein with both orotate phosphoribosyl transferase and orotidylate decarboxylase activity. The most frequently observed inborn error of pyrimidine nucleotide synthesis is a mutation of the multifunctional protein UMP synthase. As a result, plasma orotic acid accumulates to high concentrations, and increased quantities appear in the urine. Orotic acid levels are elevated in the urea cycle defects ornithine transcarbamylase (OTC) deficiency, citrullinemia and argininosuccinic acidemia, as well as the mitochondrial transport disorder hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome. Orotic acid is also elevated in hereditary orotic aciduria, or uridine monophosphate synthase deficiency, an autosomal recessive disorder characterized by megaloblastic anemia and crystalluria. In addition, orotic acid in combination with leflunomide is in the phase II of clinical trial to evaluate the clinical efficacy and safety of a combination in kidney transplant patients with high levels of Polyoma BK viruria for the purpose of preventing polyoma BK viremia and nephropathy, that could lead to kidney transplant loss from viral damage, acute rejection or both.

Ethenzamide is an anti-inflammatory agent that was used for the treatment of common cold in Japan (in combinations with other NSAIDs).
