Application Note

Coumarin, also known as bisfuran cyclooxaphthalone, is a lactone compound widely found in Rutaceae and Umbelliferae. Coumarin is a general term for a class of natural products with a benzo-αpyrone structure, which is widely used in medicine, fragrance, dyes, instrument analysis, agriculture and other fields.

Indole exists in many natural products such as indole alkaloids, fungal metabolites and marine natural products. Indole derivatives have been found to contain a variety of biological activities, including antibacterial, antibiotic, anti-inflammatory, analgesic, anticonvulsant, antimalarial, anticancer, antiulcer, antileishmaniasis, contraceptive, antioxidant, etc.

Benzimidazole is an electron-rich aromatic heterocyclic compound containing two N atoms that can form complexes with metal ions containing empty orbitals. As an important targeting pharmacophore, the high therapeutic potential of benzimidazole drugs has inspired medicinal chemists to explore the synthesis of novel chemotherapeutic agents containing benzimidazole moieties.

Pyridine is a unique nitrogen-containing aromatic ring compound. Besides being widely used in industry, pyridine is also present in many natural products such as vitamins, coenzymes and alkaloids. Pyridine compounds are often used in medicine due to their basicity, water solubility, stability, hydrogen bond formation ability and small molecular size. In addition, the substitution of pyridine rings plays an important role in drug discovery.

Piperidine is a chemical compound that has been widely used in drug development, particularly in the synthesis of pharmaceuticals. It is a cyclic amine that is commonly used as a building block in the synthesis of various drugs due to its unique chemical properties. Another application of piperidine in drug development is its use as a scaffold for the design of new drugs. Medicinal chemists use piperidine as a starting point to develop new drugs with improved pharmacological properties.

Aromatic ring building blocks are organic compounds that contain benzene rings or other aromatic ring structures. The development of new drugs can benefit from the usage of aromatic rings as essential building blocks. They are utilized to produce a variety of chemical structures and functional groups that can communicate with particular biological targets. Moreover, liposomes, micelles, and other delivery systems that may be directed at particular tissues and cells can be made using aromatic rings as platforms for drug administration.
