Mangwegape, Daisy K.;Zuma, Nonkululeko H.;Aucamp, Janine;N’Da, David D. research published 《 Synthesis and in vitro antileishmanial efficacy of novel benzothiadiazine-1,1-dioxide derivatives》, the research content is summarized as follows. Leishmaniasis is a major vector-borne parasitic disease that affects thousands of people in tropical and subtropical developing countries. In 2019 alone, it killed 26,000-65,000 individuals. Leishmaniasis is curable, yet its eradication and elimination are hampered by major hurdles, such as the availability of only a handful of clin. toxic drugs and the emergence of pathogenic resistance against them. This underscores the imperative need for new and effective antileishmanial drugs. In search for such agents, we synthesized and evaluated the in vitro antileishmanial potential of a small library of benzothiadiazine derivatives by assessing their activity against the promastigotes of three strains of Leishmania and toxicity in healthy cells. The derivatives were found to have no toxicity to the mammalian cells and were, in general, active against all parasites. The benzothiadiazine derivative 1e, 3-methyl-2-[3-(trifluoromethyl)benzyl]-2H-benzo[e][1,2,4]thiadiazine 1,1-dioxide, was found to be the most active (IC50, 0.2μM) against Leishmania major, responsible for the most prevalent disease form, cutaneous leishmaniasis. Conversely, benzothiadiazine 2c, 2-(4-bromobenzyl)-3-phenyl-2H-benzo[e][1,2,4]thiadiazine 1,1-dioxide, was the most potent (IC50, 6.5μM) against Leishmania donovani, a causative strain of the lethal visceral leishmaniasis. Both compounds stand as antipromastigote hits for further lead investigation into their potential to act as new antileishmanial agents.

Controlling the spatial confinement effect and highly dispersed Pd nanoparticles (NPs) can help to improve applicability in catalysis, energy conversion, and separation However, the nonspatial confinement effect, agglomeration of Pd NPs of catalyst and harsh reaction conditions have become the urgent problems to be solved in Suzuki-Miyaura cross-coupling reaction. Herein, authors report the first application of a new MOFs@COFs by using core with metal organic frameworks (MOFs) NH₂-MIL-101(Fe) and shell with covalent organic frameworks (COFs) for loading Pd NPs. The quickly formation of a transition state, the highly dispersed Pd NPs and the advancedly spatial confinement effect were achieved by coupling Fe base synergistic active components, electron-oriented anchoring with controlling pore scale, resp. Most notably, as a proof-of-concept application, the high catalytic activity of NH₂-MIL-101(Fe)@Pd@COFs(3 + 3) in catalysis is elucidated for Suzuki-Miyaura coupling reaction by the broad scope of the reactants and the preeminent yields of the products, together with excellent stability and recoverability. With this strategy, the mechanism of Suzuki-Miyaura coupling reaction was verified by examining the catalytic activity. Authors hope that their approach can further facilitate the study of the design and use of functional MOFs@Pd@COFs materials.
