Tropisetron
Product name:Tropisetron
CAS: 89565-68-4
Molecular Formula: C17H20N2O2
Molecular Weight: 284.35
Product description:Product is a peripheral and central nervous system neurons within 5 - HT3 receptor of selective inhibitors. Anticancer drugs or radiation can stimulate the intestinal mucosa chromaffin cells release 5 - HT3, induce the gag reflex, causing nausea and vomiting. This product selectivity in the reflection and weeks of the nervous system the excitement of presynaptic 5 - HT3 receptors, and May 5 - HT on the central nervous system. Receptor passed after the introduction of the vagus nerve area has a direct impact, this dual role in the process of blocking the gag reflex of chemical neurotransmitter, and vomiting caused by chemotherapy and radiotherapy has a therapeutic effect.

Tryptophan
Product name:Tryptophan
CAS: 73-22-3
Molecular Formula: C11H12N2O2
Molecular Weight: 204.23
Product description:This product is a white or yellowish crystalls or crystal powder. Odourless and slightly bitter taste. Melting point of 281 ~ 282 ℃ (right), 289 ℃ decomposition, left-handed. Raceme slightly soluble in water (0.4%, 25 ℃) and ethanol, soluble in formic acid, dilute acid and dilute alkali, insoluble in chloroform and ether. 0.2% of the aqueous solution pH 5.5 ~ 7.0.This product is an important nutrients. May take part in the update of the plasma protein in animals, and riboflavin can play a role, will also help nicotinic acid and synthesis of hemoglobin, can significantly increase the animal births seed antibodies in pregnancy, lactation cows and sows have promote lactation. When lack of tryptophan of livestock and poultry, stunted growth, weight loss, fat accumulation is reduced, sire testicular atrophy. In medicine, as with the skin disease prevention and control of agent.
