Design, synthesis and structure-activity relationship of dihydrobenzoquinolines as novel inhibitors against influenza A virus.

Novel dihydrobenzo[h]quinolines (DHBQs), the products of an efficient catalyst-free three-component reaction (3CR) recently developed by us, possess useful and strong aggregation-induced emission (AIE) characteristic. Here, a series of new dihydrobenzo[h]quinolines (h-DHBQs 4-1-34) and dihydrobenzo[f]quinolines (f-DHBQs 5a-e) were designed and synthesized by the 3CR to study their bioactivities as novel inhibitors against the influenza A (H1N1) virus. The structure-activity relationship (SAR) indicates that the antiviral activities of DHBQs depend on the combination of substituents and three of h-DHBQs (4-12, 4-25 and 4-27) show potent antiviral activity with IC = 2.

In situ synthesis and electrochemical performance of MoO nanobelts as anode materials for lithium-ion batteries.

MoO nanobelts with different concentrations of oxygen vacancies were synthesized by a one-step hydrothermal process. XPS test results show that oxygen vacancies are distributed from the exterior to the interior of the MoO nanobelts. As an anode material for lithium-ion batteries, MoO-10 releases excellent rate capacitance.

Effect of sulfur doping on structural reversibility and cycling stability of a LiMnSiO cathode material.

Based on the existing calculation reports, sulfur doping is an effective approach to alleviate the structure collapse of Li2MnSiO4 during cycling. Herein, we investigate the feasibility and limitations of S doping in Li2MnSiO4 by experiment. In our work, the solid solubility of S is confirmed and exceeding the threshold results in MnS impurity.
