Milrinone
Milrinone is a member of the class of bipyridines that is 2-pyridone which is substituted at positions 3, 5, and 6 by cyano, pyrid-4-yl, and methyl groups, respectively. It is used (particularly intravenously, as the lactate) for the short-term management of severe heart failure. It has a role as an EC 3.1.4.17 (3,5-cyclic-nucleotide phosphodiesterase) inhibitor, a platelet aggregation inhibitor, a vasodilator agent and a cardiotonic drug. It is a pyridone, a nitrile and a member of bipyridines. Heart failure is a multifactorial condition that affects roughly 1-2\\% of the adult population. Often the result of long-term myocardial ischemia, cardiomyopathy, or other cardiac insults, heart failure results from an inability of the heart to perfuse peripheral tissues with sufficient oxygen and metabolites, resulting in complex systemic pathologies. Heart failure is underpinned by numerous physiological changes, including alteration in β-adrenergic signalling and cyclic adenosine monophosphate (cAMP) production, which affects the hearts contractile function and cardiac output. Milrinone is a second-generation bipyridine phosphodiesterase (PDE) inhibitor created through chemical modification of [amrinone]. As a PDE-III inhibitor, milrinone results in increased cAMP levels and improves cardiac function and peripheral vasodilation in acute decongested heart failure. Milrinone was originally synthesized at the Sterling Winthrop Research Institute in the 1980s. It was approved by the FDA on December 31, 1987, and was marketed under the trademark PRIMACOR® by Sanofi-Aventis US before being discontinued. Milrinone is a Phosphodiesterase 3 Inhibitor. The mechanism of action of milrinone is as a Phosphodiesterase 3 Inhibitor. Milrinone is a cardiovascular bipyridine agent and phosphodiesterase (PDE) III inhibitor, with positive inotropic and vasodilator activities. Upon administration, milrinone selectively inhibits PDE-mediated degradation of cyclic adenosine monophosphate (cAMP) in the heart and vascular muscles, thereby increasing cAMP and activates protein kinase A (PKA). This leads to phosphorylation of calcium ion channels and improve myocardium contractile force. Milrinone also causes vasodilation in arteriolar and venous vascular smooth muscle. A positive inotropic cardiotonic agent with vasodilator properties. It inhibits cAMP phosphodiesterase type 3 activity in myocardium and vascular smooth muscle. Milrinone is a derivative of amrinone and has 20-30 times the inotropic potency of amrinone. See also: Milrinone Lactate (active moiety of). Milrinone is only found in individuals that have used or taken this drug. It is a positive inotropic cardiotonic agent with vasodilator properties. Milrinone inhibits erythrocyte phosphodiesterase, resulting in an increase in erythrocyte cAMP activity. Subsequently, the erythrocyte membrane becomes more resistant to deformity. Along with erythrocyte activity, Milrinone also decreases blood viscosity by reducing plasma fibrinogen concentrations and increasing fibrinolytic activity. It also inhibits cAMP phosphodiesterase activity in myocardium and vascular smooth muscle. Milrinone is a derivative of amrinone and has 20-30 times the ionotropic potency of amrinone.

Methyldopa
Methyl dopa appears as colorless or almost colorless crystals or white to yellowish-white fine powder. Almost tasteless. In the sesquihydrate form. pH (saturated aqueous solution) about 5.0. (NTP, 1992) Alpha-methyl-L-dopa is a derivative of L-tyrosine having a methyl group at the alpha-position and an additional hydroxy group at the 3-position on the phenyl ring. It has a role as a hapten, an antihypertensive agent, an alpha-adrenergic agonist, a peripheral nervous system drug and a sympatholytic agent. It is a L-tyrosine derivative and a non-proteinogenic L-alpha-amino acid. Methyldopa, or α-methyldopa, is a centrally acting sympatholytic agent and an antihypertensive agent. It is an analog of DOPA (3,4‐hydroxyphenylanine), and it is a prodrug, meaning that the drug requires biotransformation to an active metabolite for therapeutic effects. Methyldopa works by binding to alpha(α)-2 adrenergic receptors as an agonist, leading to the inhibition of adrenergic neuronal outflow and reduction of vasoconstrictor adrenergic signals. Methyldopa exists in two isomers D-α-methyldopa and L-α-methyldopa, which is the active form. First introduced in 1960 as an antihypertensive agent, methyldopa was considered to be useful in certain patient populations, such as pregnant women and patients with renal insufficiency. Since then, methyldopa was largely replaced by newer, better-tolerated antihypertensive agents; however, it is still used as monotherapy or in combination with [hydrochlorothiazide]. Methyldopa is also available as intravenous injection, which is used to manage hypertension when oral therapy is unfeasible and to treat hypertensive crisis. Methyldopa anhydrous is a Central alpha-2 Adrenergic Agonist. The mechanism of action of methyldopa anhydrous is as an Adrenergic alpha2-Agonist. Methyldopa (alpha-methyldopa or α-methyldopa) is a centrally active sympatholytic agent that has been used for more than 50 years for the treatment of hypertension. Methyldopa has been clearly linked to instances of acute and chronic liver injury that can be severe and even fatal. Methyldopa is a phenylalanine derivative and an aromatic amino acid decarboxylase inhibitor with antihypertensive activity. Methyldopa is a prodrug and is metabolized in the central nervous system. The antihypertensive action of methyldopa seems to be attributable to its conversion into alpha-methylnorepinephrine, which is a potent alpha-2 adrenergic agonist that binds to and stimulates potent central inhibitory alpha-2 adrenergic receptors. This results in a decrease in sympathetic outflow and decreased blood pressure. Methyldopa or alpha-methyldopa (brand names Aldomet, Apo-Methyldopa, Dopamet, Novomedopa) is a centrally-acting adrenergic antihypertensive medication. Its use is now deprecated following introduction of alternative safer classes of agents. However it continues to have a role in otherwise difficult to treat hypertension and gestational hypertension (formerly known as pregnancy-induced hypertension). Methyldopa is an aromatic-amino-acid decarboxylase inhibitor in animals and in man. Only methyldopa, the L-isomer of alpha-methyldopa, has the ability to inhibit dopa decarboxylase and to deplete animal tissues of norepinephrine. In man the antihypertensive activity appears to be due solely to the L-isomer. About twice the dose of the racemate (DL-alpha-methyldopa) is required for equal antihypertensive effect. Methyldopa has no direct effect on cardiac function and usually does not reduce glomerular filtration rate, renal blood flow, or filtration fraction. Cardiac output usually is maintained without cardiac acceleration. In some patients the heart rate is slowed. Normal or elevated plasma renin activity may decrease in the course of methyldopa therapy. Methyldopa reduces both supine and standing blood pressure. Methyldopa usually produces highly effective lowering of the supine pressure with infrequent symptomatic postural hypotension. Exercise hy...

Methyldopa usually produces highly effective lowering of the supine pressure with infrequent symptomatic postural hypotension. Exercise hypotension and diurnal blood pressure variations rarely occur. Methyldopa, in its active metabolite form, is a central alpha-2 receptor agonist. Using methyldopa leads to alpha-2 receptor-negative feedback to sympathetic nervous system (SNS) (centrally and peripherally), allowing peripheral sympathetic nervous system tone to decrease. Such activity leads to a decrease in total peripheral resistance (TPR) and cardiac output. When introduced it was a mainstay of antihypertensive therapy, but its use has declined, with increased use of other safer classes of agents. One of its important present-day uses is in the management of pregnancy-induced hypertension, as it is relatively safe in pregnancy compared to other antihypertensive drugs (Wikipedia).

3-Methoxytyrosine
3-Methoxytyrosine, also known as 3-O-methyldopa or vanilalanine, belongs to the class of organic compounds known as tyrosine and derivatives. Tyrosine and derivatives are compounds containing tyrosine or a derivative thereof resulting from reaction of tyrosine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. 3-Methoxytyrosine is one of the main biochemical markers for Aromatic L-amino acid decarboxylase (AADC, EC4.1.1.28) deficiency, an inborn error of metabolism that affects serotonin and dopamine biosynthesis. Chronically high levels of 3-methoxytyrosine are associated with aromatic L-amino acid decarboxylase (AADC, 28) deficiency, an inborn error of metabolism that affects serotonin and dopamine biosynthesis. 3-Methoxytyrosine is a potentially toxic compound. 3-Methoxytyrosine, with regard to humans, has been found to be associated with several diseases such as epilepsy, early-onset, vitamin b6-dependent and pyridoxamine 5-prime-phosphate oxidase deficiency; 3-methoxytyrosine has also been linked to several inborn metabolic disorders including sepiapterin reductase deficiency and aromatic l-amino acid decarboxylase deficiency. 3-Methoxytyrosine is one of the main biochemical markers for Aromatic L-amino acid decarboxylase (AADC, EC 4.1.1.28) deficiency, an inborn error of metabolism that affects serotonin and dopamine biosynthesis. Patients are usually detected in infancy due to developmental delay, hypotonia, and extrapyramidal movements. Diagnosis is based on an abnormal neurotransmitter metabolite profile in CSF and reduced AADC activity in plasma. 3-methoxytyrosine is elevated in CSF, plasma, and urine.
