In the title compound, C(5)H(5)N(3)O(3), the nitro group is twisted with respect to the amide group, with C-N-N-O torsion angles of 29.0 (2) and -153.66 (14)°. In the crystal, mol-ecules are linked through inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming supra-molecular chains along the a axis. These chains stack in parallel and form distinct layer motifs in the (001) plane.

In the title mol-ecule, C(8)H(11)NO(2), the r.m.s. deviation of non-H atoms from their best plane is 0.031 Å. Mol-ecules are connected via a pair of N-H⋯O hydrogen bonds into a centrosymmetric dimer.

Six new conjugates were designed and synthesized by introducing glucose, methyl glucuronate or glucuronic acid moieties on tralopyril. Phytotoxicity and phloem mobility results demonstrated that the introduction of glucose, methyl glucuronate or glucuronic acid moieties can simultaneously solve the tough phytotoxicity problem and phloem mobility transformation of tralopyril. Conjugates 12 and 1...

Using bipolar electrochemistry, carbon paper (CP) is asymmetrically coated with copper metal. Subsequent anodic electrodissolution in a solution containing trimesic acid linkers results HKUST-1 depositing on the surface. The CP-MOF (metal organic framework) composite then soaked pyrrole/isopropanol for several hours before undergoing oxygen/Cu-induced polymerization to fill pores. Variations co...

A guanidiniocarbonyl pyrrole (GCP) cation forms stable H-bond assisted ion pairs with carboxylates even in aqueous solutions. A tetra GCP cation 1 undergoes efficient two-component self-assembly with Na4EDTA, a tetra-carboxylate, leading to 3D supramolecular networks. These networks show dual pH responsiveness and reversibly dissociate back into monomers upon addition of either acid or base.

We studied the mechanism of action of 3,5-dibromo-4-(3,4-dimethoxyphenyl)-1H-pyrrole-2-carboxylic acid ethyl ester (JG-03-14) and found that it is a potent microtubule depolymerizer. JG-03-14 caused a dose-dependent loss of cellular microtubules, formation of aberrant mitotic spindles, accumulation of cells in the G(2)/M phase of the cell cycle, and Bcl-2 phosphorylation. These events culminate...

This Highlight provides an overview of the molecular logic employed in the formation and elaboration of pyrroles during natural product biosyntheses. The pyrrole ring, either in its unadorned form or as the pyrrole-2-carboxylate moiety commonly encountered in natural products, possesses many useful chemical and electronic features that are readily exploited in biological contexts. The ring itse...

Food fraud and adulteration are the global issues, currently. One important issue is about gelatine since it comes from many sources of animals. Therefore, analytical method for must be developed used authentication. This study was conducted to investigate Volatile Compounds (VCs) Maillard Reaction Products (MRPs) which responsible their aroma. Three standards bovine, fish porcine bought Sigma ...
