Pyrrole is a five membered heterocyclic compound with the molecular formula of C4H5N. Pyrrole has a ring composed of four carbon atoms and one nitrogen atom. Pyrrole is easy to polymerize in the air. Pyrrole is the parent compound of many important biological substances (such as bile pigment, porphyrin and chlorophyll). Pyrrole scaffolds are widely used in biological and pharmaceutical fields. Pyrrole is a special heterocyclic scaffold, which exists in many natural products, drug molecules and pesticides, and has shown its application in materials science.

Pyrrole is a heterocyclic, aromatic, organic compound, a five-membered ring with the formula C 4H 4NH. It is a colorless volatile liquid that darkens readily upon exposure to air. Substituted derivatives are also called pyrroles, e.g., N-methylpyrrole.
Pyrimidine, also known as 1,3-diazobenzene, is a heterocyclic compound with the chemical formula C4H4N2. Pyrimidine is formed by substituting 2 nitrogen atoms for 2 carbons in the meta-position of benzene. It is a diazine and retains its aromaticity. Derivatives of pyrimidine widely exist in organic macromolecular nucleic acids, and many drugs also contain pyrimidine rings. In nucleic acids, three nucleobases are pyrimidine derivatives: cytosine, thymine and uracil. There are a variety of pyrimidine-containing drugs on the market, most of which are kinase inhibitors.
Pyrrolidine, also known as tetrahydropyrrole, is a saturated five-membered heterocyclic ring, which is miscible with water. Pyrrolidine exists in many alkaloids and drug molecules, such as kappa opioids, antagonists of dopamine D4 receptors, and HIV reverse transcriptase inhibitors.
