Be a powerful technique for convenient detection of pH change in living cells, especially at subcellular level, fluorescent probes has attracted more and more attention. In this work, we designed and synthesized three rhodamine lactam modulated fluorescent probes RS1, RS2 and RS3, which all respond sensitively toward weak acidity (pH range 4-6) via the photophysical property in buffer solution without interference from the other metal ions, and they also show ideal pKa values and excellent reversibility. Particularly, by changing the lone pair electrons distribution of lactam-N atom with different conjugations, RS2 and RS3 exhibit high quantum yield, negligible cytotoxicity and excellent permeability. They are suitable to stain selectively lysosomes of tumor cells and monitor its pH changes sensitively via optical molecular imaging. The above findings suggest that the probes we designed could act as ideal and easy method for investigating the pivotal role of H+ in lysosomes and are potential pH detectors in disease diagnosis through direct intracellular imaging.

The paper contains results of statistical and chemometric analysis for 15 thiourea derivatives containing the 3-amino-1,2,4-triazole moiety and characterized by antimicrobial activity against Staphylococcus aureus (NCTC 4163, ATCC 25923, ATCC 6538, ATCC 29213), Staphylococcus epidermidis (ATCC 12228) bacteria, as well as by low cytotoxicity (or lack thereof) against infected MT-4 cells. Multiple regression and cluster analysis were employed to perform the study. The research enabled obtaining linear relationships connected with three molecular descriptors SA, eta, logP. The conducted chemometric analyses indicate that the increase in activity against the studied strains is closely related to the type and position of substituent in a phenyl ring.

Bacillus sp. are well-known biocontrol agents against various fungal plant pathogens. The present work was conducted for characterization of antagonistic Bacillus sp., isolated from tomato rhizosphere, and its control mechanisms against Fusarium oxysporum f. sp. lycopersici. A collection of 49 Bacillus isolates was obtained from the rhizosphere of tomato plants from infested field. Dual culture antagonism assay was carried out to assess the potential role of the strains against the pathogen. The evaluation of the strains was done for their antifungal ability and plant growth promoting properties including beta-1,3-glucanase, protease, chitinase, ammonia, siderophore, hydrogen cyanide, IAA and biofilm formation. Strain B44, identified as Bacillus sp. based on ribotyping (Accession no. MG779639), which exhibited maximum number of antifungal properties tested, was selected for further study. The strain was capable of producing hydrolytic enzymes such as beta-1,3-glucanase (15.61 U ml?1 min?1), protease (1608.15 U ml?1 min?1), and chitinase (129 U ml?1 min?1), volatiles and non-volatile metabolites. Volatiles were extracted by solid phase micro extraction (SPME) technique. The major compounds identified by GC-MS analysis were 1,2-benzenedicarboxylic acid (23.99%), 6-undecylamine (6.61%), 2-methyloctacosane (5.91%), 9-octadecenoic acid (5.13%) and 1-tetradecanamine, N,N-dimethyl (5.05%). The prominent compounds identified by UPLC-MS were tert-butyl difluorophosphine (31.45%), 5-(4,4,5,5-tetramethyl-1, 3, 2-dioxaborolan-2-yl)-3,6-dihydro-2H-pyran (14.76%), 6-bromo-4-tert-butyl-1,1-dimethyl-1,2-dihydronaphthalene (8.35%), 2-amino-N-butyl-1,8-naphthyridine-3-carboxamide (6%), N,N-diethyl-2-[(ethylamino)methyl]-3-phenyloxirane-2-sulfonamide (5.12%). The isolate showed approx. 36% reduction in disease incidence in tomato plant under green house conditions and could serve as an efficient agent for biocontrol of wilt disease in tomato.

Recent advances in understanding different RNAs and unique features of their biology have revealed a wealth of information. However, approaches to identify small molecules that target these newly discovered regulatory elements have been lacking. The application of new biochemical screening and design-based technologies, coupled with a resurgence of interest in phenotypic screening, has resulted in several compelling successes in targeting RNA. A number of recent advances suggest that achieving the long-standing goal of developing drug-like, biologically active small molecules that target RNA is possible. This review highlights advances and successes in approaches to targeting RNA with diverse small molecules, and the potential for these technologies to pave the way to new types of RNA-targeted therapeutics.

A series of novel 4-isochromanone compounds bearing N-benzyl pyridinium moiety were designed and synthesized as acetylcholinesterase (AChE) inhibitors. The biological evaluation showed that most of the target compounds exhibited potent inhibitory activities against AChE. Among them, compound 1q possessed the strongest anti-AChE activity with an IC50 value of 0.15?nm and high AChE/BuChE selectivity (SI?>?5,000). Moreover, compound 1q had low toxicity in normal nerve cells and was relatively stable in rat plasma. Together, the current finding may provide a new approach for the discovery of novel anti-Alzheimer’s disease agents.
