Aim: Simultaneous modulation of several key targets of the pathological network of Alzheimer’s disease (AD) is being increasingly pursued as a promising option to fill the critical gap of efficacious drugs against this condition. Materials & Methods: A short series of compounds purported to hit multiple targets of relevance in AD has been designed, on the basis of their distinct basicities estimated from high-level quantum mechanical computations, synthesized, and subjected to assays of inhibition of cholinesterases, BACE-1, and Abeta42 and tau aggregation, of antioxidant activity, and of brain permeation. Results: Using, as a template, a lead rhein-huprine hybrid with an interesting multitarget profile, we have developed second-generation compounds, designed by the modification of the huprine aromatic ring. Replacement by [1,8]-naphthyridine or thieno[3,2-e]pyridine systems resulted in decreased, although still potent, acetylcholinesterase or BACE-1 inhibitory activities, which are more balanced relative to their Abeta42 and tau antiaggregating and antioxidant activities. Conclusion: Second-generation naphthyridine- and thienopyridine-based rhein-huprine hybrids emerge as interesting brain permeable compounds that hit several crucial pathogenic factors of AD.

Due to the deleterious effects of mercury on human health and natural ecosystems, high reactivity, non-degradability, extreme volatility and relative water and tissue solubility, it would consider as one of the most toxic environmental pollutants among the transition metals. In the present investigation, we have tried to summarized the several organic material based fluorescent sensor including rhodamine, boron-dipyrromethene (BODIPYs), thiourea, crown-ether, coumarine, squaraines, pyrene, imidazole, triazole, anthracene, dansyl, naphthalenedimide/ naphthalene/ naphthalimide, naphthyridine, iridium (III) complexes, polymeric materials, cyclodextrin, phthalic anhydride, indole, calix [4]arene, chromenone, 1,8-naphthalimides, lysine, styrylindolium, phenothiazine, thiocarbonyl quinacridone, oxadiazole, triphenylamine?triazines, tetraphenylethene, peptidyl and semicarbazone for the trace mercury detection in the aqueous, aqueous?organic and cellular media. The present review provides a brief look over the previous development in the organic material based fluorescent sensor for mercuric ion detection. Furthermore, the ligand-metal binding stoichiometry, binding/association/dissociation constants and the detection limit by the receptors have been particularly highlighted which might be useful for the future design and development of more sensitive and robust fluorescent chemosensor/chemodosimeter for the mercuric ion detection.

Much recent attention has been focused on small organic molecules binding to non-canonical structures of nucleic acids, especially, RNA. The Human Genome Project and the ENCODE (encyclopedia of DNA elements) project revealed that more than 75% of the human genome is transcribed into RNA, while only ?3% of the human genome encodes a protein. These non-protein-coding RNAs are thought to play significant roles in many cellular processes and are promising targets for drug discovery. Emerging roles of the non-coding RNAs in a variety of diseases provides enormous opportunities for pharmaceutical research on developing drugs targeting undruggable and rare diseases. During the last two decades, our laboratory has focused attention on small molecules binding to non-canonical DNA and RNA structures, especially to mismatched base pairs. Mismatch binding ligands (MBLs) we have developed are synthetic molecules designed in silico based on the hypothesis of hydrogen-bonding and semi-intercalation to DNA and RNA. Most of MBLs consists of two heterocycles having hydrogen bonding surfaces fully or partially complementary to that of nucleotide bases. In our design, each heterocycle binds to one of the mismatched bases by hydrogen bonding to form pseudo-base pairs, which would be stacked with the adjacent base pairs. The hypothesis allows us in principle to design small molecules binding to any mismatched base pairs, but it turned out not to be the case in reality. However, we have so far succeeded in developing several MBLs binding to DNA and RNA motifs of biological significance. In this review, we shall describe the hypothesis of molecular design of MBLs and its outcome regarding RNA targeting.

Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: Ethyl 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 96568-07-9

The palladium-catalyzed coupling of 3- and 4-(trialkylstannyl)pyridines with 7-bromo or 7-chloro 1-substituted 1,4-dihydro-4-oxo-3-quinolinecarboxylates has provided access to the corresponding 1-substituted 1,4-dihydro-4-oxo-7-pyridinyl-3-quinolinecarboxylic acids.The antibacterial activity of these derivatives was studied with the finding that the optimal 1- and 7-position substituents for Gram positive activity are cyclopropyl and 4-(2,6-dimethylpyridinyl), respectively.We find that for the fluorine-substituted derivatives studied, the position of the fluorine on the quinolone nucleus or the number of fluorine atoms does not seem to be important for good Gram positive activity.For 1-cyclopropyl 7-(2,6-dimethyl-4-pyridinyl) derivatives, the 6-fluoro 4a, 8-fluoro 10d, 6,8-difluoro 10b, and 5,6,8-trifluoro 8, all provided equal antibacterial activity against Staphylococcus aureus ATCC 29213.There is also a correlation between the substitution on the 7-(4-pyridynyl) group and the Gram positive activity, particularly for S. aureus, clearly indicating that the 2,6-dimethylpyridil group is optimal.The MIC50 value for the most potent agents in this study against S. aureus ATCC 29213 is 0.008 mug/mL.By comparison, ciprofloxacin and aminopyrrolidine 28 gave values of 0.25 and 0.015 mug/mL, respectively, against this organism.

Reactive oxygen species (ROS) play an important role in many critical physiological processes. However, overproduction and accumulation of ROS in vivo can damage some biomolecules and lead to a variety of diseases. Therefore, it is necessary to develop efficient methods for the detection of ROS. Spectroscopic probes have been extensively employed in this respect because of their high sensitivity and superior spatiotemporal sampling capability. In this review, representative spectroscopic probes for the common ROS developed in the recent 5?years are summarized, and discussed according to design strategies and recognition groups.
