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.

A series of 1H-pyrrolo[2,3-c]pyridines as acid pump antagonists (APAs) was synthesized and the inhibitory activities against H + /K + ATPase isolated from hog gastric mucosa were determined. After elaborating on substituents at N1, C5, and C7 position of 1H-pyrrolo[2,3-c]pyridine scaffold, we have observed that compounds 14f and 14g are potent APAs with H + /K + ATPase IC 50 = 28 and 29 nM Cited by: 7.

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.
2 Naturally occurring bisindolylmethanes such as vibrindole A (1) are useful in the treatment of fibromyalgia Cited by: Azaindoles exhibit significant biological activity and help facilitate the generation of new therapeutic leads.
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.
