Carboprost tromethamine price
Product name:Carboprost tromethamine
CAS: 58551-69-2
Molecular Formula:C21H36O5.C4H11NO3
Molecular Weight: 489.64
Product description:Muscle ZhuSheKa other tromethamine can stimulate the gravid uterus muscular contraction, similar to the end of the full-term pregnancy childbirth contraction. It is unable to determine whether the contract due to the card other direct effects on myometrium and cause. However, in most cases, the shrinkage can make pregnancy outcome. Postpartum women after use, can be in uterine muscle contraction placenta parts play a role of the bleeding. Card other tromethamine can also stimulate the human gastrointestinal smooth muscle, when card other tromethamine is used to terminate a pregnancy or postpartum use, can cause vomiting or diarrhea or both are common. Experimental animals and humans can make the body temperature after use. Termination of pregnancy and postpartum use therapeutic doses of card other tromethamine, some patients do a temporary increase in the temperature. Experimental animals and humans using large dose of card other tromethamine after can cause high blood pressure, this may be related to its cause vascular smooth muscle contraction.

Buy Terlipressinum
Product name:Terlipressinum
CAS: 14636-12-5
Molecular Formula: C52H74N16O15S2
Molecular Weight: 1227.37
Product description:A new type of synthetic long-acting vasopressin preparations, chemical name three ammonia acyl lysine vasopressin, belongs to a kind of precursor drugs, itself is inactive, the body through the aminopeptidase, take off the ends of their N 3 after ammonia acyl residues, slow "release" of a reactive lysine vasopressin. It is this "slow release" mechanism, make its can maintain smooth muscle contraction after a drug for 10 hours, and equivalent dose vasopressin, its active only for 20 to 40 minutes. Slowly, on the other hand, due to the enzyme solution cycle of lysine vasopressin reach toxic levels, therefore, the use of vasopressin is safe.

Exenatideacetate price
Product name:Exenatideacetate
CAS: 141732-76-5
Molecular Formula: C184H282N50O60S
Molecular Weight: 4186.6
Product description:Im fall blood sugar, such as glucagon like peptide 1 (glp-1), from the intestinal released into the circulation after dependence may improve glucose insulin secretion, and show the other high blood sugar medicine resistant. Asay the peptide is quasi im fall blood sugar, medicine, can simulate glucose dependent function and intestinal fall blood sugar, insulin secretion increase other resisting high blood sugar medicine. Essex the peptide sequence of amino acids and human glp-1 overlap. Essex in vitro showed that peptides can combine and activation of known human glp-1 receptor. This means that by including cAMP and/or other intracellular signal transduction mechanisms of glucose insulin dependent synthesis and islet beta cells secrete insulin in the body. In the case of elevated glucose concentration, Essex peptide can promote the insulin release from the beta cells. Body after dosing asay the glp-1 peptides simulation of a certain resistance to high blood sugar medicine effect.

Serotonin price
Product name:Serotonin
CAS: 153-98-0
Molecular Formula: C10H13ClN2O
Molecular Weight: 212.68
Product description:An inhibitory neurotransmitter, the earliest found in blood serum, widely exists in mammalian tissues, high content in the cerebral cortex and synapses. The tissues, serotonin is a potent vasoconstrictor and smooth muscle contraction stimulants. Serotonin can enhance memory, and can protect neurons from damage by "excited nerve poison". Such as glutamic acid or for the damage to the nerve cells are quite toxic, so plenty of serotonin can prevent brain damage occurred in the process of aging.
