The compound can be purified through recrystallization from an appropriate solvent.Formula:C31H36BrNO3Purity:Min. 95%Molecular weight:550.53 g/molAripiprazole EP Impurity E
CAS:Aripiprazole EP Impurity E is a potential impurity of aripiprazole, which is an antipsychotic drug. It has been detected as a major impurity in the drug. Aripiprazole EP Impurity E has been found to be present in human plasma and it is thought that this impurity may have pharmacological effects on humans similar to those of aripiprazole. The detection of this impurity has been achieved using LC-MS/MS methods. This method can be used for wastewater treatment due to the matrix effect of nitrogen atoms. Aripiprazole EP Impurity E may have significant implications in the diagnosis, prevention, and treatment of obesity and other metabolic disorders.Formula:C23H25Cl2N3O2Purity:Min. 95%Molecular weight:446.37 g/molSceptrin dihydrochloride
CAS:Sceptrin dihydrochloride is a natural product that is the first asymmetric synthesis of the sceptrin molecule. It has been shown to have anti-inflammatory properties and can be used for the treatment of inflammatory bowel disease. Sceptrin dihydrochloride inhibits the activity of leukotriene A4 hydrolase, which is an enzyme that controls the production of leukotrienes. This inhibition leads to decreased levels of leukotrienes and reduced inflammation in the gastrointestinal tract. Sceptrin dihydrochloride has also been shown to have an effect on skeleton cells, where it can inhibit bone resorption by activating osteoclasts and inhibiting osteoblasts. Sceptrin dihydrochloride belongs to a group of compounds called fatty acid esters and has a chemical structure consisting of nitrogen atoms with two chiral centers. The synthesis was carried out using an asymmetric synthesis method that involved reaction with a chiral catalyst andFormula:C22H26Br2Cl2N10O2Purity:Min. 95%Molecular weight:693.2 g/molDRI-c21045
CAS:DRI-c21045 is an analog of a medicinal compound that has been shown to inhibit the activity of a specific protein kinase involved in cell cycle regulation and tumor growth. This inhibitor has been demonstrated to induce apoptosis in cancer cells, making it a promising candidate for anticancer therapy. DRI-c21045 has been tested in both Chinese and human cancer cell lines and has shown potent activity against various types of tumors. Additionally, this compound has been detected in urine samples from patients with cancer, suggesting that it may have potential as a diagnostic marker for certain types of cancer. Overall, DRI-c21045 shows great promise as a potential anticancer agent with significant therapeutic potential.
