A series of tacrine-based pyrazolo[4?,3?:5,6]pyrano[2,3-b]quinolines and related compounds were designed and synthesized for targeting AChE, BuChE and 15-LOX enzymes in the field of Alzheimer’s disease therapy. Most of compounds showed potent activity against cholinesterases and mild potency toward 15-LOX enzyme. In particular, compounds 29, 32 and 40 displayed inhibition at nano-molar level against AChE and BuChE (IC50s?=?0.005?0.08?muM), being more potent than reference drug tacrine. Moreover, compound 32 with IC50value of 31?muM was the most potent compound against 15-LOX. The cytotoxicity assay on HepG2 cells revealed that compounds 29 and 32 showed no significant cytotoxic activity even at concentration of 50?muM. The cytotoxicity of compounds 29 and 32 was significantly less than that of tacrine at higher concentrations.

A new three-step procedure for pyridine annulation is described and illustrated with efficient syntheses of various 1,6-, 1,7-, and 1,8-naphthyridin-2-ones as well as 6-chloroquinolin-2-one.The regiospecific ortho metalation and subsequent formylation of 2-, 3-, or 4-(pivaloylamino)pyridines provides the corresponding protected ortho aminopyridinecarboxaldehydes as key intermediates in this procedure.After condensation of these aldehydes with tert-butyl lithioacetate the resulting beta-hydroxy esters are treated with refluxing aqueous HCl to generate the naphthyridine system in excellent yield.Naphthyridines with diverse substitution patterns in eighter of the pyridine rings are available by appropriate modification of the overall pyridine annulation sequence.

Cross-coupling reactions, namely, the Suzuki?Miyaura, Heck, Sonogashira, Hiyama, Negishi, Kumada, and Hartwig?Buchwald, are the most powerful approaches in the formation of C?C, C?N, C?O, and C?S bonds for the complex organic scaffolds in drugs, natural products, organic materials, and fine chemicals. The nitrogen-based ligands have upper hands in these reactions because they are air stable, inexpensive, and easier to handle than the phosphorous counterparts. In this perspective, Schiff bases and N-heterocyclic carbenes have been explored extensively in terms of novel design and preparation as ligands in the coupling reactions. Facile recovery and reusability of these ligands make them eco-friendly and economical. A comprehensive outline on the progress in Schiff bases?metal complexes and NHC?metal complexes that mediated cross-coupling reactions with recent examples highlighted is reported (160 references).

Ebola virus (EBOV) causes a deadly hemorrhagic fever in humans and non-human primates. There is currently no FDA-approved vaccine or medication to counter this disease. Here, we report on the design, synthesis and anti-viral activities of two classes of compounds which show high potency against EBOV in both in vitro cell culture assays and in vivo mouse models Ebola viral disease. These compounds incorporate the structural features of cationic amphiphilic drugs (CAD), i.e they possess both a hydrophobic domain and a hydrophilic domain consisting of an ionizable amine functional group. These structural features enable easily diffusion into cells but once inside an acidic compartment their amine groups became protonated, ionized and remain trapped inside the acidic compartments such as late endosomes and lysosomes. These compounds, by virtue of their lysomotrophic functions, blocked EBOV entry. However, unlike other drugs containing a CAD moiety including chloroquine and amodiaquine, compounds reported in this study display faster kinetics of accumulation in the lysosomes, robust expansion of late endosome/lysosomes, relatively more potent suppression of lysosome fusion with other vesicular compartments and inhibition of cathepsins activities, all of which play a vital role in anti-EBOV activity. Furthermore, the diazachrysene 2 (ZSML08) that showed most potent activity against EBOV in in vitro cell culture assays also showed significant survival benefit with 100% protection in mouse models of Ebola virus disease, at a low dose of 10 mg/kg/day. Lastly, toxicity studies in vivo using zebrafish models suggest no developmental defects or toxicity associated with these compounds. Overall, these studies describe two new pharmacophores that by virtue of being potent lysosomotrophs, display potent anti-EBOV activities both in vitro and in vivo animal models of EBOV disease.

Oxygenation of 1,5-cyclooctadiene (COD) is achieved on an iridium center using water as a reagent. A hydrogen-bonding interaction with an unbound nitrogen atom of the naphthyridine-based ligand architecture promotes nucleophilic attack of water to the metal-bound COD. Irida-oxetane and oxo-irida-allyl compounds are isolated, products which are normally accessed from reactions with H2O2 or O2. DFT studies support a ligand-assisted water activation mechanism.
