Alpha blockers
Alpha blockers are pharmaceutical compounds that work by inhibiting the activity of alpha-adrenergic receptors, which are responsible for the contraction of smooth muscles. These medications are commonly used to treat conditions such as high blood pressure and benign prostatic hyperplasia by causing blood vessels to relax and widen. At CymitQuimica, we provide a range of alpha blockers suitable for research in pharmacology and cardiovascular health.

CAS:<p>4-Amino-2-chloro-6,7-dimethoxyquinazoline (4ACDMQ) is a synthetic compound that has been used as a chemical intermediate. The chemical structure of 4ACDMQ is similar to that of the natural amino acid tryptophan. It is synthesized by reacting phosphorus pentachloride with 2,6,7-trimethoxyquinazoline in the presence of hydroxide solution and hexamethylphosphoramide. 4ACDMQ has been shown to be an inhibitor of ubiquitin proteasome system and has been used in functional studies on this system. The reaction yield for 4ACDMQ can be increased by using sodium hydroxide solution or n-dimethyl formamide as a solvent. Functional assays have shown binding properties for 4ACDMQ to proteins such as ubiquitin and proteasome subunits.</p>Formula:C10H10ClN3O2Purity:Min. 95%Color and Shape:PowderMolecular weight:239.66 g/molTrazodone hydrochloride impurity C

CAS:<p>Leflunomide is a drug that belongs to the class of pyridones. It is used in the treatment of rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, and ankylosing spondylitis. Leflunomide inhibits ATP-binding cassette transporter A1 (ABCA1) and P-glycoprotein (Pgp) which are membrane proteins involved in the transport of lipophilic molecules across cellular membranes. Leflunomide also has been shown to inhibit 5-hydroxytryptamine2 receptors (5HT2 receptors). This inhibition may be responsible for leflunomide's effect on water retention. Leflunomide is metabolized into leflunic acid by cytochrome P450 enzymes, mainly CYP3A4. The activity of leflunic acid is similar to that of leflunomide.</p>Formula:C19H21N5O4Purity:Min. 95%Molecular weight:383.4 g/molTrazodone Hydrochloride Impurity G
