One-pot sequential synthesis of 3-carbonyl-4-arylbenzo[f]indole and 3-carbonyl-4-arylnaphthofuran fluorophores

The development of novel methods for the construction of valuable fluorophores, 3-carbonyl-4-arylbenzo[f] indoles and 3-carbonyl-4-arylnaphthofurans, is described. In this protocol, the important polycarbonyl key intermediate was generated via the ketonization of ortho-alkynylarylketone tethered with a 1,3-dicarbonyl moiety. This intermediate reacted with an amine to selectively form a pyrrole intermediate, followed by cyclization in acetic acid to provide 3-carbonyl-4-arylbenzo[f] indole. Importantly, these conditions did not cause any epimerization of the stereogenic center in chiral amine substrates. Moreover, the polycarbonyl intermediate could also be utilized to prepare 3-carbonyl-4-arylnaphthofuran using In (OTf) 3 as a catalyst for double cyclization under thermal conditions. In addition, the fluorescence properties of both fluorophores were also studied.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 574-98-1. HPLC of Formula: C10H8BrNO2.

Effect of sub-minimal inhibitory concentration ceftazidime on the pathogenicity of uropathogenic Escherichia coli

Uropathogenic Escherichia coli (UPEC) is the most prevalent causative agent of urinary tract infections (UTIs). The pathogenicity of UPEC relies on the expression of virulence factors which could be regulated by intercellular signal molecules. Our previous study found that sub-minimal inhibitory concentration ceftazidime (sub-MIC CAZ) could inhibit the biofilm formation of E. coli by luxS/AI-2 or indole. Therefore, we speculated that sub-MIC CAZ might affect the pathogenic capacity of UPEC. In this study, the results showed that sub-MIC CAZ could significantly inhibit the adhesion ability, biofilm formation and swimming and swarming motilities of UPEC isolated from recurrent UTI patient. Meanwhile, obvious decreased hemolytic activity and cytotoxicity were observed in CAZ-pretreated UPEC. Furthermore, qRT-PCR results confirmed the downregulating ability of CAZ on the expression of adhesion genes, motility genes, toxin gene and signal molecule synthesis genes, which are important for virulence and biofilm formation of UPEC. Pre-treatment of UPEC with sub-MIC CAZ resulted in the reduced adhesion to human bladder epithelial cell 5637 and the decreased numbers of intracellular bacterial communities in cells. Consistent with the results in vitro, the pretreatment of CAZ resulted in the reduction of UPEC load in the bladder and the less severity of UPEC-induced inflammation compared with control group. The present study results indicated that sub-MIC CAZ could decrease the pathogenicity of UPEC and might be served as an effective antimicrobial agent to combat recurrent UTI caused by UPEC.

Electrochemical Regioselective Phosphorylation of Nitrogen-Containing Heterocycles and Related Derivatives

The site-selective functionalization of biologically important nitrogen-containing heterocycles and related derivatives remains a challenging and important task. We report herein on the direct regiodivergent N1/C2 phosphorylation of free indole derivatives. Cyclic voltammograms and EPR data indicate that by utilizing different electrolyte-mediated anodic oxidation to generate different active indole species, a diverse collection of N1 and C2 phosphorylation products could be obtained in moderate to high yields under exogenous-oxidant-free and metal-catalyst-free electrochemical conditions. In addition, N-P coupling was also found to be compatible with various alkylamines.

Cyclopiazonic acid induced p53-dependent apoptosis in the testis of mice: Another male related risk factor of infertility

Cyclopiazonic acid (CPA) is an indole tetrameric acid mycotoxin. This study carried out to investigate the potential effects of CPA on male reproductive system. In the current study, 40 adult male mice were divided into five groups (n = 8). The control group did not expose to CPA, while animals in vehicle-received group; received the CPA-solvent (0.05% dimethyl sulfoxide) and the animals of third, fourth, and fifth groups received CPA 0.03, 0.06, and 0.12 mg/kg, body weight, respectively for 28 days. Morphometric and morphological deviations, spermatogenesis indices, malondialdehyde (MDA) content, total thiol molecules (TTM) concentration, total antioxidant capacity (TAC), protein carbonylation rate (CO), and nitric oxide (NO) concentration were examined. The expression changes of apoptotic genes (P53, Bcl-2, and Caspase III) at mRNA level were also evaluated by qPCR technique. Reduction in the Leydig and Sertoli cells population, diameter of seminiferous tubules, and spermatogenesis parameters was significant only in the group that received the highest dose of CPA. An increase in the level of MDA, NO, and CO in testicular tissue and reduction of TAC and TTM were observed in the CPA-exposed groups. Significant up-regulation (p < .05) in the expression of P53 and Caspase III genes and down-regulation of Bcl-2 gene were found in the CPA-received groups. These results are indicating the detrimental effects of CPA on the testicles, which may attribute to the CPA-induced oxidative stress and apoptosis. Moreover, results also help to understand a serious concern about the presence of CPA in foods as a potential risk factor in male-related infertility. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 78415-72-2, in my other articles.
