Synthesis and Pharmacochemistry of New Pleiotropic Pyrrolyl Derivatives.

Synthesis and Pharmacochemistry of New Pleiotropic

Within the framework of our attempts to synthesize pleiotropic anti-inflammatory agents, we have synthesized some chalcones and their corresponding 3,4-pyrrolyl derivatives. Chalcones constitute a class of compounds with high biological impact. They are known for a number of biological activities, including anti-inflammatory and free radical scavenging activities. They inhibit several enzymes i...

Pyrrolyl-, 2-(2-thienyl)pyrrolyl- and 2,5-bis(2-thienyl)pyrrolyl-nucleosides: synthesis, molecular and electronic structure, and redox behaviour of C5-thymidine derivatives.

A series of modified nucleosides based on thymidine have been prepared by Pd-catalysed cross-coupling between N-alkyl-alkynyl functionalised pyrrolyl- (py), 2-(2-thienyl)pyrrolyl- (tp) or 2,5-bis(2-thienyl)pyrrolyl (tpt) groups with 5-iodo-2'-deoxyuridine. The length of the alkyl chain linking the nucleoside and pyrrolyl-containing unit, N(CH(2))(n)C[triple bond, length as m-dash]C-nucleoside (...

Synthesis and Molecular Modeling of Novel Pyrrolyl Oxadiazole Derivatives as Antimycobacterial Agents

Synthesis and Spectroscopic Characterization of a Series of New Anthralin Derivatives and Their Corresponding Spiro-Hetherocycles

Several 10-substituted anthralins were readily prepared. Their oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone gave the corresponding novel heteroatomic systems. All derivatives were fully characterized by IR, Mass and 1HNMR spectroscopy.  

Exploring the coordination modes of pyrrolyl ligands in bis(imido) uranium(VI) complexes.

The preparation of a family of bis(imido) uranium(VI) complexes stabilized by mono- and bidentate pyrrolyl ancillary ligands is described. X-ray crystallographic studies of dipyrrolylmethane (dpm) derivatives show that the pyrrolyl coordination mode in these uranium(VI) ions is unexpected in comparison to analogous transition metal and lanthanide chemistry. The ability of the coordinated pyrrol...
