Quinazoline and Quinoline Derivatives
Quinazolines and quinolines are nitrogen-containing heterocyclic compounds with aromatic structures that play a key role in the synthesis of drugs with anticancer, antimicrobial, and anti-inflammatory activity. Their derivatives feature structural modifications that optimise bioavailability and selectivity, enabling the development of new active ingredients for various therapeutic applications. These compounds are used in the manufacture of APIs for the treatment of cancer, infections, neurodegenerative diseases, and cardiovascular conditions. Additionally, quinazoline and quinoline derivatives are essential in the research of enzyme inhibitors and the design of innovative bioactive molecules.
At CymitQuimica, we offer high-purity quinazoline and quinoline derivatives for applications in chemical synthesis, pharmaceutical development, and biotechnology.

CAS:N2-Methyl alfuzosin-D7 is a drug product that belongs to the group of alfuzosin, which is a selective inhibitor of the enzyme phosphodiesterase type 5 (PDE5) and is used for the treatment of benign prostatic hyperplasia. It has been designed to reduce the risk of adverse effects associated with other PDE5 inhibitors, such as erectile dysfunction and urinary retention. N2-Methyl alfuzosin-D7 has been shown to be effective in animal studies and in vitro experiments. However, its metabolism remains unknown.Formula:C19H21D7ClN5O4Purity:Min. 95%Molecular weight:432.95 g/molHaloperidol Decanoate EP Impurity C HCl

CAS:1,1-Bis-(methylthio)-2-nitroethene is a versatile molecule that can be used as an imine. It is synthesized by reacting trifluoromethanesulfonic acid with the amine in the presence of a base. The imine product has been shown to bind to amines and is therefore a potential drug candidate for prostate cancer cells. 1,1-Bis-(methylthio)-2-nitroethene reacts with triflic acid to produce an intramolecular hydrogen bond, leading to its efficient synthesis. The resulting compound then undergoes reactions that are characterized by nmr spectra and profiles. This functional group is inhibitory against prostate cancer cell lines at high concentrations, although it has no effect on other cell lines.Formula:C4H7NO2S2Purity:Min. 95%Molecular weight:165.24 g/mol1-(1-BENZYL-1H-PYRAZOL-4-YL)-1H-INDOLE-3-CARBOXYLIC ACID
