decarboxylation

Pheneturide (Benuride) is the ureide class, used to treat epilepsy, and is an anticonvulsant.

L-DOPA (Levodopa) is an orally active metabolic precursor of the neurotransmitter dopamine. It can cross the blood-brain barrier and be converted into dopamine in the brain. L-DOPA exhibits anti-hyperalgesic effects and holds potential in Parkinson’s disease research, and it can also be used to induce Parkinson’s disease models.

Histamine (Ergamine) is an amine derived by the enzymatic decarboxylation of histamine. Histamine is a potent stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and a neurotransmitter of central action.

Dopamine hydrochloride (ASL279) is a natural catecholamine neurotransmitter that mainly acts on dopamine receptors (D1-5 receptors) (EC50=2.7 nM). Dopamine hydrochloride induces VEGFR2 endocytosis through D2 dopamine receptor and has pro-angiogenic activity.

Pyridoxal phosphate (Vitamin B6 phosphate) is the active form of vitamin B6 and a coenzyme for many pyridoxal phosphate (PLP)-dependent enzymes. PLP is involved in numerous enzymatic transamination, decarboxylation and deamination reactions; it is necessary for the synthesis of amino acids and amino acid metabolites, and for the synthesis and/or catabolism of certain neurotransmitters, including the conversion of glutamate into gamma-aminobutyric acid (GABA) and levodopa into dopamine. PLP can be used as a dietary supplement in cases of vitamin B6 deficiency. Reduced levels of PLP in the brain can cause neurological dysfunction.

Phenylpropiolic acid (3-Phenylpropiolic acid) is an enzyme extinguishing agent used in palladium-catalyzed decarboxylation coupling reactions.

Thiamine pyrophosphate (Cocarboxylase) is a vitamin B-1 derivative that acts as a coenzyme of transketolase. Thiamine pyrophosphate is used in studies to assess decarboxylation mechanisms in biological systems.

Tyramine hydrochloride is a biogenic trace amine that is generated via the decarboxylation of the amino acid tyrosine, exhibiting neuromodulatory properties as well as cardiovascular and immunological effects.

Succinyl phosphonate is a selective α-ketoglutarate dehydrogenase (α-KGDHC ) and OGDHC inhibitor that inhibits α-ketoglutarate oxidative decarboxylation. Succinyl phosphonate trisodium salt inhibits glutamate-induced ROS generation in glutamate-stimulated hippocampal neurons and can be used to study neurodegenerative diseases.

α-Lipoic acid is a cyclic disulfide antioxidant that interconverts with its reduced dithiol form. It is an essential cofactor for decarboxylation reactions of the citric acid cycle and acts as a general antioxidant. AN-7 is a more lipophilic analog of α-lipoic acid with enhanced potency and 1.5-fold increased maximal capacity to stimulate glucose transport into myocytes. This identifies the analogs of lipoic acid as potential new treatments for diabetes.

3-Iodothyronamine is derived from the deiodination and decarboxylation of endogenous thyroxine. It activates the G protein-coupled receptor known as trace amine-associated receptor 1 at nanomolar concentrations whereupon it rapidly influences thyroid hormone actions including body temperature, heart rate, and cardiac output. It has also been reported to function in controlling lipid and glucose utilization, hormonal secretion, and neuronal function, and has been considered for use in chemically-induced hibernation for medical purposes.

Alamandine can be formed from angiotensin A by action of ACE-2 or directly from angiotensin-(1-7) by decarboxylation of its aspartate residue. The angiotensin A analog produces effects resembling those of Ang II (1-7). However, it acts independently of the two known vasodilators receptors of the RAS (Mas and angiotensin II type 2). To produce its effects, alamandine binds to the Mas-related receptor, MrgD. A novel orally active formulation of alamandine produced a long-term antihypertensive effect in spontaneously hypertensive rats and cardioprotective effects. These novel findings will be helpful for developing a new understanding of the RAS, a key regulator of blood pressure and fluid balance. The heptapeptide could serve as a model peptide, e.g. in the development and evaluation of analytical methods.

Phosphatidylethanolamine (PE) contains phospholipids found in mammals, formed by decarboxylation of phosphatidylserine.

(±)-Jasmonic acid (trans-Jasmonic acid) is a compound found in grapevine inflorescences and fruits with pro-aging activity, inhibiting chlorophyll levels in green and yellowing barley leaf segments, suppressing rice seedling elongation, and participating in biogenic amine chemical coupling through decarboxylation with both aliphatic and aromatic α-amino acids.

Tyrosine decarboxylase (TDC; TyrDC), a pyridoxal 5'-phosphate (PLP)-dependent enzyme, catalyzes the decarboxylation of tyrosine, leading to the production of tyramine and carbon dioxide. This enzyme is prevalent in plants, insects, and various microorganisms, playing a significant role in biochemical research.

Isocitrate dehydrogenase (ICDH), a critical enzyme in the citric acid or tricarboxylic acid cycle, facilitates the oxidative decarboxylation of isocitrate to α-ketoglutarate while reducing NAD(P)+ to NAD(P)H, thus playing pivotal roles in cellular metabolism [1].

Vinclozolin M2, an active metabolite of vinclozolin, is generated through successive esterase activity and decarboxylation in C. elegans, as well as decarboxylation in human liver microsomes. It functions as an antagonist to the mineralocorticoid (IC50= 1,400 nM) and androgen receptors (IC50= 0.17 nM), demonstrated in reporter assays with MCF-7 cells. This compound is exclusively sold for research and analytical purposes, tailored for controlled laboratory use, and is not available in bulk sizes.

Fmoc-L-Lys(4-N3-Z)-OH is a chemical reagent characterized by its azide group. This compound serves as a lysine building block in solid-phase peptide synthesis (SPPS) with azide functionality, useful as a bioorthogonal handle, an infrared probe, and a photoaffinity label. It undergoes strain-promoted 1,3-dipolar cycloaddition facilitated by trans-cyclooctene decarboxylation. Additionally, Fmoc-L-Lys(4-N3-Z)-OH functions as a click chemistry reagent, enabling copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with molecules containing alkyne groups. Moreover, it can participate in strain-promoted alkyne-azide cycloaddition reactions (SPAAC) with molecules that possess DBCO or BCN groups.

L-Dopa-2,5,6-d3 is a deuterated compound of L-Dopa. L-Dopa has a CAS number of 59-92-7. Levodopa is an amino acid precursor of dopamine with antiparkinsonian properties. Levodopa is a prodrug that is converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. When in the brain,  levodopa is decarboxylated to dopamine and stimulates the dopaminergic receptors, thereby compensating for the depleted supply of endogenous dopamine seen in Parkinson's disease. To assure that adequate concentrations of levodopa reach the central nervous system, it is administered with carbidopa, a decarboxylase inhibitor that does not cross the blood-brain barrier, thereby diminishing the decarboxylation and inactivation of levodopa in peripheral tissues and increasing the delivery of dopamine to the CNS.
