Validamycin

Product name:Validamycin
CAS: 37248-47-8
Molecular Formula: C20H35NO13
Molecular Weight: 497.49
Product description:Refinement for white crystalline, without certain melting point, decomposition of 130 ~ 135 ℃. Hygroscopicity strong, soluble in methanol, dioxane, dimethyl formamide, hardly soluble in acetone, ethanol, not soluble in ether, benzene, chloroform, carbon tetrachloride, hyaluronic acid ethyl ester, such as organic solvents, soluble in water. When the pH value of 4 ~ 5, the more stable in 0.2 mol/L 105 ℃, 10 h in sulfuric acid decomposition, can be a variety of microbial decompose the deactivation.Mainly used for rice sheath blight, can also be used for rice paddy song disease, corn size spot disease as well as vegetables, beans and cotton crop disease prevention and control. Years of large-scale field using results fully show its 'high control effect, no phytotoxicity, no pollution' of the characteristics of environmental protection pesticides.

Velpatasvir

Product name:Velpatasvir
CAS: 1377049-84-7
Molecular Formula: C50H55N7O8
Molecular weight:882.01
Stability:Stable
Shelf life:2 years
Product description :Velpatasvir is both an inhibitor and a substrate of the transporter proteins P-glycoprotein (Pgp), ABCG2, OATP1B1 and OATP1B3. It is partly degraded by the liver enzymes CYP2B6, CYP2C8 and CYP3A4. Substances that are transported or inactivated by these proteins, or interfere with them, can interact with velpatasvir.

Venlafaxine

Product name:Venlafaxine
CAS: 93413-69-5
Molecular Formula: C17H27NO2
Molecular Weight: 277.4
Product description:Mainly through the drug at the same time blocking NE reuptake and 5 - HT, higher concentration of NE and 5 - HT and give play to the role of double antidepressant, heavy intake of dopamine (DA), only a slight inhibition. For M choline receptor, adrenaline alpha 1, alpha, beta 2 receptor, histamine H1 receptor almost no affinity. 0 - to its active metabolites methyl enlafaxine may also inhibit 5 - HT and NE heavy intake, activity is lower than prototype drug. Research has shown that this product in small doses is mainly inhibiting the reuptake of 5 - HT, large doses of 5 - HT and NE reuptake inhibition. The drug for 5 - HT reuptake inhibition weaker than selective 5 - HT heavy uptake inhibitor (SSRI); On NE reuptake inhibition is also weak in some tricyclic antidepressants (TCA) or selective NE reuptake inhibitor.
