Pyrroles (1 H -pyrroles) are heterocyclic aromatic compounds consisting of a five-membered ring containing a nitrogen atom. Pyrroles are important synthons in the synthesis of natural products. They exhibit remarkable biological properties such as hypolipidemic, antimicrobial, anti-inflammatory and antitumour activities and are able to inhibit retroviral reverse transcriptases [i.e., human.

Pyrrole is a heterocyclic aromatic organic compound, a five-membered ring with the formula C 4 H 4 NH. It is a colorless volatile liquid that darkens readily upon exposure to air. Substituted derivatives are also called pyrroles, e.g., N-methylpyrrole, C 4 H 4 NCH 3.

Porphobilinogen, a trisubstituted pyrrole, is the biosynthetic precursor to many natural products such as ein Reference: Molecular Weight: g/mol.

these compounds are regarded as potential high-energy-density materials with nontoxic products. At the same time, the very high heat of formation and related instability have made experimental investigations of these compounds very difficult, and much of the work on this subject has been theoretical in.

1. Introduction. Bisindolylmethane scaffolds are present in many natural products isolated from both terrestrial and marine natural sources. 1 These natural products exhibit a broad range of biological activity including anticancer activity against several common cancer cell-lines.

The azaindole moiety exhibits excellent potential as a bioisostere of the indole ring system, differing from indole only by the presence of an additional ring nitrogen. Although more rare in nature, they comprise essential subunits in the synthesis of many pharmaceutically relevant.
