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.

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 1143-70-0. Category: indole-building-block.

Aggregation-induced emission with white, green, or blue luminescence from biologically-active indole derivatives

Among several advantages of single-chromophore white-light-emitting dyes over mixed dyes are their phase stability and fabrication low-cost. Also, materials with aggregation-induced emission (AIE) have been employed as good bioprobes for DNA and for detecting some biomacromolecules sensitively and selectively. To be suitable for biological applications, the molecule should have AIE properties and be biocompatible. Indoles are electron-rich unsaturated compounds that display photophysical properties with potential applications such as fluorescent probes in addition to their widespread biological activities. Materials characterized with white-color emission, AIE activity, and biocompatibility are presented in this work. The thermal behavior and photophysical properties of some indole derivatives have been studied experimentally and theoretically using density functional theory. Besides their reported biological activities, the studied indole dyes show high thermal stabilities and ME behavior. Some dyes gave white-color luminescence from a single chromophore, while others produced blue or green emissions. Theoretical and experimental results indicate that the different emission behavior of these dyes resulted from forming various kinds of aggregates with different intermolecular interactions.
