Radiolabeling of Siamenoside I with Carbon-14.

The synthesis of radiolabeled [25-C]-siamenoside I following a synthetic route developed using unlabeled materials is disclosed. The synthesis features an early stage labeling of the mogrol's C25 an oxidative cleavage-reconstruction strategy and regioselective glycosylations directed by protecting group manipulations. This route provided access to adequate amounts of [25-C]-siamenoside I for ADME and PK studies.

A novel class of insecticidal alkylsulfones are potent inhibitors of vesicular acetylcholine transport.

Pyridine alkylsulfone derivatives typified by oxazosulfyl (Sumitomo Chemical Company Ltd.) and compound A2 (Syngenta) represent a new class of insecticides, with potent activity against several insect orders. Whilst the MOA of this class has been attributed to interaction with the voltage-gated sodium channel (VGSC), here we present strong evidence that their toxicity to insects is mediated primarily through inhibition of the vesicular acetylcholine transporter (VAChT).

Synthesis and insecticidal activity of N-(5-phenylpyrazin-2-yl)-benzamide derivatives: Elucidation of mode of action on chitin biosynthesis through symptomology and genetic studies.

Among the six-membered heterocycles, the pyrazine ring is poorly explored in crop protection and does not feature in any product listed in the current IRAC MoA classification. In an effort to identify new leads for internal research, we synthesized a series of N-(5-phenylpyrazin-2-yl)-benzamide derivatives and evaluated them for their insecticidal activity. N-(5-phenylpyrazin-2-yl)-benzamide derivatives 3 were prepared using an automated two-step synthesis protocol.

Mindfulness in Politics: A Qualitative Study on Mindfulness Training in the UK Parliament.

Objectives: While mindfulness in the workplace has received substantial scientific attention in the past decades, it is not yet well-understood if, under what circumstances, and in what ways mindfulness training may be helpful for individuals working in political environments. The aim of this study was to explore the experience of mindfulness training among British politicians, as well as mindfulness facilitators who had taught mindfulness to politicians in the UK Parliament.

Method: Between September and November 2021, semi-structured in-depth interviews were conducted with British politicians ( = 18) who had experience of mindfulness training and mindfulness facilitators ( = 4) who had taught mindfulness to politicians in the UK Parliament.
