<p>Applications L-Citrulline-d7, is the labeled analogue of L-Citrulline (C535700), which is an amino acid, first isolated from the juice of watermelon, Citrullus vulgaris Schrad., Cucurbitaceae. It is also used in the treatment of asthenia.<br>References Kurtz, et al.: J. Biol. Chem., 122, 477 (1938), Rajantie, J., et al.: J. Pediatr., 97, 927 (1980), Carpenter, T.O., et al.: N. Engl. J.

<p>Applications DL-Methionine methylsulfonium chloride (cas# 3493-12-07) is a useful research chemical.<br></p>

<p>Applications 2,2'-AZOBIS-(2-METHYLBUTYRONITRILE) (cas# 13472-08-7) is a useful research chemical.<br>Dangerous Goods Info This compound is forbidden to ship by air under IATA regulations.<br></p>

<p>(1R,2S,3S,5S)-3-(4-Iodophenyl)-8-methyl-8-azabicyclo[3.2.1]octane-2-carboxylicacid methyl ester is a molecule that has been shown to be effective in lowering the symptoms of Parkinson's disease. It also prevents the uptake of dopamine and serotonin in the brain by binding to dopamine and serotonin transporters on the cell membrane. This drug has been shown to be safe at doses up to 100 mg/kg/day in rats, but has not been tested in humans. The drug is stable in neutral pH environments and does not degrade upon exposure to light or oxygen.</p>

<p>7-[5-(Fluoro-methyl-phosphoryl)oxypentyl]-4-nitro-2,1,3-benzoxadiazole is a reactivator of the central nervous system. It is a noncompetitive antagonist at muscarinic receptors and blocks postsynaptic acetylcholine release from cholinergic neurons. It has been shown to have no effect on blood pressure but does cause an increase in locomotor activity in animals. This drug binds to the hippocampal formation and the ventral hippocampus, which are areas of the brain that are involved in memory and spatial navigation. The distribution of this drug postulated to be due to its ability to penetrate micron sized openings in cell membranes.</p>

<p>Gly-Asp-OH is a medicine that has proliferative activity. It is also an immunoregulatory and biologically active substance, which suppresses the production of cytokines IL-10 in mononuclear cells. Gly-Asp-OH is a synthetic compound with medicinal properties. The structure of this compound was elucidated by chemical analysis and spectroscopic methods. It can be used as an anti-inflammatory agent or to prevent cell death induced by necrosis or apoptosis.</p>

<p>(Fluoro-Methylphosphoryl)Oxycyclohexane is an organophosphorus compound that acts as a nerve agent. It inhibits the enzyme acetylcholinesterase, which is responsible for breaking down acetylcholine, leading to excess cholinergic stimulation. This can cause excessive contraction of muscles or even death. The exposure to (Fluoro-Methylphosphoryl)Oxycyclohexane can be detected by analytical methods such as gas chromatography/mass spectrometry. Oximes are used in the reactivation of acetylcholinesterase and are effective in preventing neuronal death. They bind to the phosphonyl group in (Fluoro-Methylphosphoryl)Oxycyclohexane and prevent it from inhibiting the enzyme acetylcholinesterase.</p>

<p>5-Methylindole-3-acetic acid (5MI3A) is a molecule that has been shown to have antiproliferative properties in bladder cancer cells. 5MI3A binds to the receptor for GABA, which is an inhibitory neurotransmitter. It also inhibits the production of proinflammatory mediators and reactive oxygen species in cancer cells. 5MI3A has anticancer activity in prostate cancer cells and may act by inducing apoptosis and inhibiting cell proliferation. Consumption of 5MI3A may reduce the risk of cancer development by preventing DNA damage from carcinogens, suppressing inflammation, and regulating cell growth through its antagonistic properties.</p>

<p>1-[3-(Fluoro-Methylphosphoryl)Oxypropyl]Pyrene is a fluorescent derivative of pyrene. It has been used to label DNA and proteins for experiments involving fluorescence. The fluorophores in 1-[3-(Fluoro-Methylphosphoryl)Oxypropyl]Pyrene are activated by laser light, which causes emission of light at a wavelength of 590 nm. The emission spectrum of 1-[3-(Fluoro-Methylphosphoryl)Oxypropyl]Pyrene is sensitive to the environment and changes with chemical modification.</p>

<p>1-(3,4-Methylenedioxyphenyl) 2-nitropropene (1-MPNP) is a phosphatase inhibitor that is active against gram-negative bacteria by inhibiting enterotoxins and chlamydia. 1-MPNP inhibits the activity of tyrosine phosphatases, which are enzymes that play a major role in bacterial virulence. 1-MPNP competitively inhibits the activity of tyrosine phosphatases and prevents them from catalyzing the hydrolysis of polyphosphate substrates. This inhibition leads to an accumulation of polyphosphates in the bacterial cell membrane, which disrupts its permeability and leads to cell death.</p>
