Considerable evidence is emerging to show the possibility of the prebiotic genesis of biological organic compounds from the primitive atmosphere. Notable among these compounds, following the synthesis of amino acids by Miller,' are dipeptides, polypeptides, proteinoids, adenine, guanine, pentose sugars, deoxyadenosine, adenosine 5'-triphosphate (ATP), nucleotides, and fatty acids, as recently s...

Solid biofuel is considered as a possible substitute for coal in household heat production because of the available and sustainable raw materials, while NOx emissions from its combustion have become serious problem. Nitrogen-containing compounds pyrolysis products important effects on conversion fuel-N into NOx-N. Understanding these converting pathways environmentally friendly use biomass fuel...

In the title compound, C(9)H(14)BNO(4), the carbonyl and boronic acid groups are essentially coplanar with the pyrrole ring and the boronic acid group has an exo-endo conformation. The exo-oriented OH is engaged in an intra-molecular O-H⋯O inter-action, while the endo-oriented one is involved in inter-molecular hydrogen bonding to form centrosymmetric dimers. A supra-molecular assembly is achie...

Several novel N substituted sulfapyridine derivatives were synthesized by condensation of 2-ChloroN-(4-(N-pyridin-2-ylsulfamoyl)phenyl) acetamide 2 with different amino acids, amines, malononitrile, or ammonium thiocyanate to yield the corresponding alkanoic acid derivatives 3a-f, acetamide derivatives 48, pyrrole derivatives 912, and thiazolidinone derivative 13. The newly synthesized compound...

4-Heteroarylidene-2-phenyl-1,3-oxazol-5(4H)-ones were prepared by reactions of hippuric acid with substituted furan-2-carboxaldehydes or furo[b]pyrrole type aldehydes. The reactivity of various furan-2-carboxaldehyde derivatives in this reaction is discussed. The effect of microwave irradiation on some condensation reactions was compared with "classical" conditions. The results show that microw...

RAW 264.7 murine macrophages were exposed to the pyrrole-based compound 3,5-Dibromo-4-(3,4-dimethoxyphenyl)-1H-pyrrole-2-carboxylic acid ethyl ester (JG-03-14), which is a known microtubule depolymerizing agent with antitumor activity [1,2,3]. In this study exposure to JG-03-14 reduced the production of pro-inflammatory molecules by macrophages activated with lipopolysaccharide (LPS). Treatment...
