Several classes of antimalarial drugs are currently available, although issues of toxicity and the emergence of drug resistant malaria parasites have reduced their overall therapeutic efficiency. Quinoline based antiplasmodial drugs have unequivocally been long-established and continue to inspire the design of new antimalarial agents. Herein, a series of mono- and bisquinoline methanamine derivatives were synthesised through sequential steps; Vilsmeier-Haack, reductive amination, and nucleophilic substitution, and obtained in low to excellent yields. The resulting compounds were investigated for in vitro antiplasmodial activity against the 3D7 chloroquine-sensitive strain of Plasmodium falciparum, and compounds 40 and 59 emerged as the most promising with IC50 values of 0.23 and 0.93 μM, respectively. The most promising compounds were also evaluated in silico by molecular docking protocols for binding affinity to the {0 0 1} fast-growing face of a hemozoin crystal model.

A new surfactant (quercetin) assisted hydrothermal method is used for the preparation of phase pure cobalt oxide (Co3O4) nanoparticles (Nps). The quercetin acted well as surfactant in producing size controlled Nps. The produced Nps were extensively characterized by various techniques to reveal its chemical composition, structure, morphology, size and thermal behavior. The main objective of the study is to employ the prepared material as heterogeneous catalyst for hydrogenation of therapeutically important aldehydes. The capability of the catalyst is appear to be good, since the yield of alcohols from structurally different aldehydes is adequate with short period of time. Also the catalyst is recyclable, stable, no need of addition of ligands for activation and environmentally benign.

The enzymes MetAP-2 and NMT play a crucial role in the process of myristoylation of oncoproteins which is deregulated in many types of cancers. Execution of both these enzymes is considered as strategy for the intervention of various cancers and relative fungal infections, and hence the discovery of novel MetAP-2 and NMT inhibitors necessitate their high relevancy. In this investigation, we have synthesized a series of novel seven-membered triazolothiadiazepinyl quinolines 10(a–m) distinctively under microwave irradiation technique and identified as selective MetAP-2 and NMT inhibitors. Amongst the functionalized derivatives when evaluated for the in vitro antifungal assay, compounds 10b, 10c, 10e and 10f were considered promising due to notable inhibitory effects (MIC = 0.2 mg/mL) on Aspergillus fumigatus. Screening of the anticancer activity against NCI-60 Human tumor cell lines portrayed that conjugates 10b, 10c, 10e and 10f were found to be moderately effective against the Renal Cancer cell line UO-31. The data acquired from biological studies was further validated by molecular docking studies and pharmacokinetic evaluation.
