Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.

From anthelmintic to neuro‐oncology: A systematic review of mebendazole repurposing for brain tumour therapy

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Mebendazole (MBZ), a benzimidazole anthelmintic with established clinical use, has emerged as a repurposing candidate for primary brain tumours due to its multimodal anticancer actions and central nervous system penetrance. This systematic review synthesizes preclinical and clinical evidence evaluating MBZ's efficacy, mechanisms of action ...

Neurofilament light chain as in vitro and clinical biomarker of vincristine‐induced peripheral neuropathy

British Journal of Clinical Pharmacology, EarlyView.
Aims Vincristine‐induced peripheral neuropathy (VIPN) is a common side effect in children and adolescents treated with vincristine. Assessing VIPN, especially in young children, is challenging due to a lack of sensitive tools. This limits our understanding of the nature and risk factors of VIPN. This study aimed to investigate neurofilament light chain
