Introduction: Quinoline is a versatile bicyclic heterocyclic scaffold with immense therapeutic potential. Some of the compounds containing quinoline nucleus are agents of choice for the treatment of various ailments, particularly cancer and malaria. Furthermore, several quinoline derivatives exhibit a broad spectrum of antimicrobial, anti-inflammatory, and antidiabetic activities, quite a few of which are under clinical investigation to combat potentially lethal diseases/disorders. Areas covered: The present review summarizes inventions developed towards finding new chemotherapeutic agents based on the quinoline skeleton. It presents an outline of patents filed between 2013 and 2015, relating to the anticancer, antimicrobial, anti-inflammatory and other biological activities exhibited by quinoline derivatives. Expert opinion: Several molecules containing quinoline skeleton are clinically significant drugs, extensively used for the treatment of various human diseases/disorders. The clinical success of some of these compounds and the versatile character of the quinoline nucleus attracted medicinal chemists in the development of newer chemotherapeutic agents. The considerably high number of patents filed in a relatively short period of time indicates the increasing importance of this pharmacophore. The development of facile synthetic strategies is anticipated to facilitate the generation of chemical libraries that could serve as a source of new chemical entities.

Liquid-liquid extraction is the major technique being applied for the partitioning of f-elements from nuclear waste. In this review, the recent developments in ligand design, optimization and extraction properties are summarised for the main classes of extractants (organophosphorus ligands, diamides and N-heterocycles), with a focus on the separation of actinides and lanthanides. Structural modifications, pre-organisation and different solvent systems, as key factors for the fine-tuning of the extraction properties, are discussed. From this review, it appears that small modifications of the structure of the ligand, the pre-organising platform or the solvent can have significant impact on the extraction (and separation) of metal ions. Interest in the combinations of ligands for the extraction processes is growing, since they provide improvements over individual ligands. Similarly, unconventional approaches are being pursued to develop more efficient and greener processes.

Within the wide range of nitrogen-containing heterocyclic compounds, the derivatives of 1,8-naphthyridine (NPTR) have gained a rising interest due to their reported versatile biological activities. The derivatives of NPTR scaffold are found to invite special interest from researchers nowadays on the significance of their manifestations of multiple attractive pharmacological activities which establish them as an effective and versatile tool in pharmaceutical chemistry and drug discovery. The diverse biological activities mainly include anti-inflammatory, antimicrobial, antiviral, anticancer, antihypertensive and analgesic activities. Novel NPTR scaffold has emerged its potency to treat neurological diseases like depression and Alzheimer’s disease. Further these agents possess different inhibitory activities, such as anti-HIV, anti-osteoporotic, alphavbeta3 antagonism, antimalarial, platelet aggregation, anti-oxidant, anti-allergic, gastric antisecretory, anticonvulsant, epidermal growth factor receptor (EGFR) inhibition, protein kinase inhibition, ionotropic properties, beta3 antagonism, phosphodiesterase 4 (PDE 4) inhibitions, adenosine receptor agonistic activity, adrenoceptors antagonism and DNA stabilizing activity, etc. In this review, we highlight the updates of different 1,8-naphthyridine derivatives and explain the key data available in the context of various biological activities of NPTR derivatives available from the literature. This may direct opportunity in researches in the synthesis of novel medicinal agents and the development of new heterocycles for modification of existing biological actions as well as evaluation of other possible pharmacological activities.

Boronic acid is known to form DD¡¤AA, DA¡¤AD, and AA¡¤DD type complexes. In this article, the ability of phenyldiboronic acid to associate with hydrogen bond acceptors (1,8-naphthyridine, 5,6,11,12-tetraazanaphthacene, 2,8a-dihydropyrano[2,3-b]pyran and 4aH-[1,4]dioxino[2,3-b][1,4]dioxine) has been analyzed in light of density functional theory. Stabilization energy and thermochemical analysis predict the feasibility of formation of DD¡¤AA type complexes between phenyldiboronic acid and N-/O-hydrogen bond acceptors. The gas and solvent phase calculations showed that the stabilization energy varies with the size of the association geometry. IR and NMR studies revealed the weakening of the O-H bond during complexation. Complexes with as many as three boronic acids and four hydrogen bond acceptors are studied and are predicted to be stable.
