Tapentadol Opioid Agonist Action Pathway

Homo sapiens
Tapentadol is a synthetic analgesic opioid with dual mechanism of action as a mu opioid agonist, and a norepinephrine reuptake inhibtor. It is an agonist of mu, kappa, and delta opioid receptors. It is also a weak serotonin reuptake inhibitor, but that doesn't contribute to the analgesic effect. Tapentadol binds to mu opioid receptors on the presynaptic membrane, stimulating the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as GABA is inhibited. Opioids close N-type voltage-operated calcium channels and open calcium-dependent inwardly rectifying potassium channels. This results in hyperpolarization and reduced neuronal excitability. Morphine acts at A delta and C pain fibres in the dorsal horn of the spinal cord. By decreasing neurotransmitter action there is less pain transmittance into the spinal cord. This leads to less pain perception.

Tasimelteon Drug Metabolism

Homo sapiens
Tasimelteon is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. Tasimelteon passes through the liver and is then excreted from the body mainly through the kidney.

Tasosartan Action Pathway

Homo sapiens
Tasosartan is a selective angiotensin II (AngII) receptor type 1 (AT1) inhibitor. It is used for the treatment of hypertension and heart failure. This drug causes the blockade of the renin-angiotensin-aldosterone system (RAAS) at the level of the AT1 receptor. Tasosartan is an antagonist of the AT1 receptors localize in the vascular muscles and the adrenal gland. This drug thus causes dilatation, reduced secretion of avsopressin (ADH), and reduced production and secretion of aldosterone.

Taurine & Hypotaurine Metabolism

Drosophila melanogaster
Taurine and hypotaurine are aminosulfinic acids. Taurine has many physiological functions as neuromodulators, membrane stabilizers, facilitator of ion transport and aiding auditory transduction. Hypotaurine has roles such as antioxidant and a protective agent. Taurine and hypotaurine are synthesized from L-cysteine. L-Cysteine is involved in cyanoacid metabolism and glutathione metabolism. L-Cysteine goes through redox reactions, elimination reactions and other metabolism pathways to eventually form taurine and hypotaurine. L-Cysteine is converted to cysteamine, which can then form hypotaurine through the enzyme cysteamine dioxygenase. L-Cysteine can also be converted to 3-sulfinoalanine through the enzyme cysteine dioxygenase. Hypotaurine can then be formed from the enzymes glutamate decarboxylase and sulfinoalanine decarboxylase acting on 3-sulfinoalanine. 3-sulfinoalanine can form taurine by first converting to L-cysteate. L-Cysteate is then metabolized to taurine via glutamate decarboxylase and sulfinoalanine decarboxylase. The hypotaurine formed in this pathway can be metabolised to taurine, then taurine is metabolised to 5-L-glutamyl-taurine by reacting with (5-L-glutamyl)-peptide via the enzyme gamma-glutamyltranspeptidase. Taurine can also undergo excretion from the organism.

Taurine and Hypotaurine Biosynthesis

Saccharomyces cerevisiae
The biosynthesis of taurine and hypotaurine is processed by the same protein, glutamate decarboxylase. Hypotaurine is produced by 3-sulfino-L-alanine reacting with glutamate decarboxylase resulting in the release of carbon dioxide and hypotaurine. Taurine is produced by L-cysteate reacting with a glutamate decarboxylase resulting in the release of Taurine and carbon dioxide
