Summary: The combination of microwaves with other classical synthetic methods provides a powerful tool for the preparation of metal oxides and metal chalcogenides. This approach allows for significant modification of reaction kinetics by reducing the processing time to minutes and minimizing energy consumption. Microwave chemistry routes have been used to produce potential thermoelectric compounds such as SnS1-xSex and Zn0.98M0.02O (M = Al, Ga) in just a few minutes. The microwave synthesis method also produces high-quality phases.

Summary: Boron monoposphide (BP) has unique physical and chemical characteristics, making it suitable for various practical applications. However, the difficult synthesis of the single phase of boron monophosphide limits its usage. Additionally, existing methods for synthesizing nanoscale BP often require high temperatures and long synthesis durations. This paper presents a simple, energy-efficient, and straightforward microwave activation synthesis method, which successfully produces pure single-phase BP nanopowder with a narrow size distribution (70-90 nm) in a short synthesis time (10 min).

Summary: The global demand for energy and industrial growth has led to a significant increase in the use of fossil fuels. In order to reduce CO2 emissions, this study explores the use of microwave irradiation as an alternative to conventional heating for zeolite A synthesis. The results demonstrate that microwave irradiation can effectively synthesize zeolite A while reducing both temperature and time.

Summary: This study identified a marine extract derived from an Australian sponge with activity against an economically important parasitic nematode. Further analysis led to the purification of four known sesterterpenes and the revision of their chemical structures. The findings suggest that these sesterterpenes deserve further investigation for their activity against nematodes.

Summary: Nine new fluorinated analogues were synthesised using late-stage functionalisation on the Open Source Malaria (OSM) triazolopyrazine scaffold. The structures of all analogues were characterised and their inhibitory activity against Plasmodium falciparum and cytotoxicity against a human embryonic kidney cell line were tested. Some compounds showed moderate antimalarial activity, while none displayed cytotoxicity at high concentrations. Substitution of CF3 and CF2H moieties at the C-8 position significantly reduced antimalarial activity, while incorporation of a CF2Me group completely abolished the effect.

Summary: The incorporation of bromine, iodine or fluorine into the tricyclic core structure of thiaplakortone A (1), a potent antimalarial marine natural product, was achieved. Although yields were low, a small library of thiaplakortone A analogues (3-11) was synthesised using a Boc-protected thiaplakortone A (2) as a scaffold for late-stage functionalisation. The antimalarial activity of the new analogues was evaluated, with the mono-brominated analogue (compound 5) showing the best activity against both drug-sensitive and drug-resistant strains of Plasmodium falciparum.

Summary: Glioblastoma is a highly lethal brain tumor with invasive spreading capabilities. This study found that blocking glutamate receptors and aquaporin-1 channels can limit the motility of tumor cells without causing harm to normal brain cells. Using combination therapy can focus the effects on cancer cells while minimizing off-target effects.

Summary: This study investigates the antifouling potential of polyphenolic resveratrol multimers isolated from two Anisoptera species found in the Papua New Guinean rainforest. The compounds showed inhibitory effects on marine microfoulers and barnacle cyprids, with (-)-hopeaphenol demonstrating strong inhibitory effects against both microalgal and bacterial adhesion. Resveratrol displayed lower antifouling activity and higher toxicity against MCR-5 fibroblasts. This study highlights the potential of natural products as a valuable source for the discovery of novel antifouling agents with low toxicity.
