papaverine profile

Papaverine is an alkaloid derived from the opium poppy. It has been used medically for over a century, primarily as a smooth muscle relaxant. Papaverine's synthesis involves complex multi-step processes, often starting from thebaine, another opium alkaloid. It acts by inhibiting phosphodiesterase, an enzyme involved in the breakdown of cyclic adenosine monophosphate (cAMP), a key signaling molecule. This leads to increased cAMP levels, which in turn relaxes smooth muscle. Clinically, papaverine is used to treat various conditions, including erectile dysfunction, peripheral vascular disease, and spasms of the digestive tract. Due to its efficacy in relaxing smooth muscle, papaverine is a valuable research tool for studying smooth muscle function and related disorders. Papaverine has been explored for potential applications in treating other conditions, such as cerebral vasospasm and pulmonary hypertension, although its use in these areas remains controversial. Despite its long history, further research into papaverine's mechanisms of action and its therapeutic potential remains ongoing.'

Papaverine: An alkaloid found in opium but not closely related to the other opium alkaloids in its structure or pharmacological actions. It is a direct-acting smooth muscle relaxant used in the treatment of impotence and as a vasodilator, especially for cerebral vasodilation. The mechanism of its pharmacological actions is not clear, but it apparently can inhibit phosphodiesterases and it may have direct actions on calcium channels.

papaverine : A benzylisoquinoline alkaloid that is isoquinoline substituted by methoxy groups at positions 6 and 7 and a 3,4-dimethoxybenzyl group at position 1. It has been isolated from Papaver somniferum.

vitamin b 6 Vitamin B 6: VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). Most of vitamin B6 is eventually degraded to PYRIDOXIC ACID and excreted in the urine.	2.34	2	0
