Alpha blockers

1-[4-(4-Amino-6,7-dimethoxy-2-quinazolinyl)-1-piperazinyl]-2-hydroxy-1-pentanone (DMPP) is an analog of the antiarrhythmic drugs flecainide and propafenone. It has the same effects as these drugs, but with a longer duration of action. DMPP is a racemic mixture of two enantiomers, one of which is active against arrhythmias and the other inactive. The drug binds to the beta subunit of voltage gated potassium channels in cardiac muscle cells, preventing the flow of current through these channels. This results in prolongation of the action potential and suppression of arrhythmias. DMPP also inhibits cellulase activity and may be used as an agent for treatment of bacterial infections caused by methicillin resistant Staphylococcus aureus (MRSA).

Trazodone hydrochloride (Trazodone HCl) is a serotonin uptake inhibitor that is used as an antidepressive agent.

Mirtazapine is a unique tetracyclic antidepressant, may cause temporary liver enzyme elevation, and is linked to rare liver injury.

2-[3-[4-(3-Chloro-4-ethylphenyl)-1-piperazinyl]propyl]-1,2,4-triazolo[4,3-a]pyridin-3(2H)-one is a research and development impurity standard. Impurities are the substances that are not intentionally added to the drug product but can be generated from the synthesis process or from the raw materials. This substance has been used as a synthetic intermediate in the production of other drugs and as an analytical reference for HPLC analysis. It is used to help develop new drugs by providing data about metabolites and possible toxic effects on humans.

1-Oxo mirtazapine is a metabolite of mirtazapine. It is a synthetic compound and is not found in nature. This product is a research and development impurity standard for the preparation of drug product, which has been synthesized to be highly pure. The material is used for drug development, including pharmacopoeia requirements for analytical studies and metabolism studies. 1-Oxo mirtazapine has been shown to have niche applications in pharmacopoeia and as an HPLC standard.

Drugs with nitrogen hetero-atom(s) only, aromatic or modified aromatic, nesoi
