The IncP-7 plasmid pCAR1 of Pseudomonas resinovorans CA10 confers the ability to degrade carbazole upon transfer to the recipient strain P. putida KT2440. We designed a customized whole-genome oligonucleotide microarray to study the coordinated expression of pCAR1 and the chromosome in the transconjugant strain KT2440(pCAR1). First, the transcriptome of KT2440(pCAR1) during growth with carbazol...

Polycyclic aromatic heterocycles, such as carbazole, are environmental contaminants suspected of posing human health risks. In this study, we investigated the degradation of carbazole by immobilized Sphingomonas sp. strain XLDN2-5 cells. Four kinds of polymers were evaluated as immobilization supports for Sphingomonas sp. strain XLDN2-5. After comparison with agar, alginate, and kappa-carrageen...

The design of small molecular ligands able to bind with DNA is pivotal for the development of diagnostic agents and therapeutic drugs targeting DNA. Carbazole-derivatives are potential agents against tumors and opportunistic infections of AIDS. Here, two carbazole-derived dicationic compounds, DPDI and DPPDI, were designed, synthesized and characterized using NMR, IR and MS. The DNA binding pro...

The synthesis of homopolymer and diblock copolymers on surfaces was demonstrated using electrodeposition of a methacrylate-functionalized carbazole dendron and subsequent reversible addition-fragmentation chain transfer (RAFT) "grafting-through" polymerization. First, the anodically electroactive carbazole dendron with methacrylate moiety (G1CzMA) was electrodeposited over a conducting surface ...

In the title mol-ecule, C18H12BrN, the 4-bromo-phenyl ring is inclined to the mean plane of the carbazole moiety (r.m.s. devation = 0.027 Å) by 49.87 (5)°. In the crystal, molecules stack along [001] and are linked by C-H⋯π interactions forming a corrugated two-dimensional network lying parallel to (100).

A carbazole-triazine hybrid was prepared by addition-elimination between carbazole and 2,4,6-trichlorotriazine in the presence of base. The compound shows intensely blue fluorescence both in solution and solid state when irradiated with UVradiation. The structure of (3) was supported by the spectroscopic data and unambiguously confirmed by the single crystal X-ray diffraction data. It was cryst...

Urea receptor 1 based on two (1-amino-8-amido-3,6-dichloro)carbazole units shows a strong association with dicarboxylate anions such as oxalate, malonate and succinate guests through multiple hydrogen bonds from the carbazole, urea and amide NH groups. (1)H NMR complexation studies exhibit high values of association constants in DMSO-d(6). X-ray structures of the 1 : 1 complexes of 1 with oxala...

In the title mol-ecule, C(18)H(12)N(2)O(4)S, the carbazole skeleton is nearly planar [maximum deviation = 0.037 (1) Å] and is oriented at a dihedral angle of 73.73 (5)° with respect to the benzene ring. An intra-molecular C-H⋯O hydrogen bond links a nitro O atom to the carbazole skeleton. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. ...

Polyhalogenated carbazoles (PHCZs) are persistent chemical pollutants increasingly detected in different environmental matrices. They structurally and chemically similar to other organic (POPs), which capable of disrupting the endocrine systems. However, PHCZs such as 3-chloro-9H-carbazole (3-CCZ), 3-bromo-9H-carbazole (3-BCZ), 36-dibromo-9H-carbazole (36-BCZ) rarely discussed context their adv...
