Doxapram hydrochloride monohydrate


Product: Doxapram hydrochloride monohydrate
CAS Number: 7081-53-0
Molecular Formula: C24H30N2O2ClCl.H2O
Molecular Weight: 432.99
Product Description: A central nervous system stimulant, part of central nervous system drugs, small doses can stimulate the body of the carotid and aortic chemoreceptor body sexual arousal reflex spinal bulb respiratory center and cardiovascular center, its breath under agitation To slow high-dose feet, high excitement of the stem of the spine and brain, but on the cerebral cortex seems no effect. In addition to the cardiovascular system have a mild stimulant effect, can cause cardiac output that mild to accelerate the pulse, moderately increase high blood pressure. Wide safety range of doxapram hydrochloride (ie, excitation dose and convulsions between large area), which is desirable to fight against fnicethamide toxins, e four Daiyin nitrogen, etc. Caused Used for respiratory depression by central inhibitory drugs, other causes of acute respiratory failure, COPD complicated with acute respiratory failure, and to speed up the relaunch of anesthesia surgery, etc.

How to buy Fluoxetine


Product Name: Fluoxetine
CAS Number: 54910 & ndash; 89-3
Molecular Formula: C17H18F3NO
Molecular Weight: 309.33
Product Description: A kind of serotonin reuptake inhibitors by inhibiting synaptic cells from the reuptake of neurotransmitter serotonin to increase extracellular boxes and serotonin levels of post-synaptic receptors. And for other receptors such as alpha adrenergic, beta-adrenergic, serotonin, dopamine can expect fluoxetine is absorbed almost no Kraft.Gut binding from the gastrointestinal tract after oral administration, the food does not alter its Bioavailability. Combined with plasma proteins much after absorption, is very widespread. Drugs reach stable plasma concentration after a few weeks.

Lercanidipine price


Product: Lercanidipine
CAS: 100427-26-7
Molecular Formula: C36H41N3O6
Molecular Weight: 611.73
Product Description: Lipotropy sex is higher, so the work is slow, and the role of a longer duration. In vivo and in vitro experiments have shown that the induced by the negative inotropic effects of nifedipine and felodipine vasodilatationseffekt low-level product; And the vascular selectivity amlodipine, group horizon felodipine and lacipidin-Ping. In addition, this product also has resistance to atherosclerosis and protects Endorganeffekte. If this product does not interfere with the management of the dose to normal cardiac excitability and conductivity of patients with hypertension. Animal studies have shown that this product has a protective effect on the kidney, its mechanism may have nothing to do with the dynamics of the blood circulation.

Nifuroxazide


Product Name: nifuroxazide
CAS: 965-52-6
Molecular formula: C12H9N3O5
Molecular Weight: 275.217
Product Description :. 1 cefuroxime nitrate Qi, prevention and treatment of e Coli, Salmonella, Pasteurella (including Bacillus on the Richter scale), Gasbazillen, Proteus, Nekrosebacillus and Staphylococcus aureus, which are caused by intestine and Harnsystemkrankheiten. Instructions of Nitrates together, can effectively prevent diarrhea, promote animal nutrition. 2, nitrate bacteria, Vibrio Qi treatment of aquatic animals and fungi cause intestinal and systemic disease, the effect of drug sensitivity in water much higher than other antimicrobial agents. 3, cefuroxime Qi nitrate, the prevention of coccidiosis of chicken, leukocytes protozoan white coronary disease and hepatitis caused by hepatitis diseases. 4, cefuroxime nitrate has a broad antimicrobial spectrum, high antibacterial activity, antibacterial concentration is low. And sulfonamides, quinolone drugs and other antibiotics without cross-resistance. , Affects almost by another stable effect of organic antibacterial power.

Synthesis and biological activity of brassinolide

Brassinolide (2 alpha, 3 alpha, 22 alpha, 23 alpha-tetrahydroxy-24 alpha-methyl-b-homo-7-oxa-5 alpha-cholestan-6-one), a plant steroid-promoting novel Rapeseed, and its unknown 22-beta-23-beta-isomers were obtained from a mixture of C-24 60:40 Dehydroxampesterol (24 alphamethylstyrene) epimers and brassicasterol (24 beta-methyl) synthesized from Of oysters. The synthesis process favored the formation of 22 beta, 23 beta. For better than the 4: 1 isomer, comparative plant of the growth promoting brassinolide capacities, both natural and synthetic, and its three cis-side chains -glycolic isomers in bean second internodal bioassay that natural and synthetic brassinolide were also active and caused a cleavage of the enters to the 0.1 microgram level. The less active were the 22 beta, 23 beta-isomer of brassinolide. The isomers with the 22 & alpha ;, 23 & alpha; And 24 & alpha; And 22 beta, 23 beta and 24 beta configurations are very active and are required at about 10 times the concentration of brassinolide, to cause the same physiological response. In the first internodal bean bioassay, an auxin-induced growth assay system isolated using bean plants resulted in the 22 beta, 23 beta and 24 beta configuration, a stronger response than brassinolide. Two of the four obtained in the synthesis of the Tetrahydroxyketone isomers are also active in both assays.

What is Calcium phosphate monobasic


Product Name: Calcium phosphate monobasic
CAS: 10031-30-8
Molecular Formula: Ca.H2O.2H2O4P
Molecular Weight: 252.06
Product Description: A phosphoric chemical porous rock phosphate crushed with the reaction of dilute sulfuric acid, the main ingredient is a calcium phosphate, the phosphorus content is 16% - 18%, the lowest component For calcium sulphate, makes about 50% of its weight in order, low phosphorus, several vice components. Under normal temperature for gray powder in dark gray, corrosive and hygroscopic, often contact with moist air easy moisture absorption cake, as the storage time is long, is a part of the phosphorus soluble in water, Water poorly soluble phosphorus and moisture, move more temperature, faster this displacement.
