An Analysis of the Diversity of Skin Colour Representation in Paediatric Nursing Practitioner Textbooks.

Aims: Our study aims to analyse 8 commonly used textbooks to determine how diverse skin tones are represented in paediatric nursing practitioner education.

Design: Literature reviewed from 2016 to 2024 demonstrated that the lack of darkly pigmented skin colour representation in health science education leads to diminished patient outcomes for these populations. Our study sought to study representation teaching images and eight commonly referenced nursing textbooks were chosen for this study, given their use in paediatric nurse practitioner education.

Verticillins: fungal epipolythiodioxopiperazine alkaloids with chemotherapeutic potential.

Covering: 1970 through June of 2023Verticillins are epipolythiodioxopiperazine (ETP) alkaloids, many of which possess potent, nanomolar-level cytotoxicity against a variety of cancer cell lines. Over the last decade, their activity and mode of action have been explored in detail. Notably, recent studies have indicated that these compounds may be selective inhibitors of histone methyltransferases (HMTases) that alter the epigenome and modify targets that play a crucial role in apoptosis, altering immune cell recognition, and generating reactive oxygen species.

Bifunctional degraders of cyclin dependent kinase 9 (CDK9): Probing the relationship between linker length, properties, and selective protein degradation.

Cyclin-dependent kinase 9 (CDK9) is a promising therapeutic target in multiple cancer types, including acute myeloid leukemia (AML). Protein degraders, also known as proteolysis targeting chimeras (PROTACs), have emerged as tools for the selective degradation of cancer targets, including CDK9, complementing the activity of traditional small-molecule inhibitors. These compounds typically incorporate previously reported inhibitors and a known E3 ligase ligand to induce ubiquitination and subsequent degradation of the target protein.

PHY34 inhibits autophagy through V-ATPase V0A2 subunit inhibition and CAS/CSE1L nuclear cargo trafficking in high grade serous ovarian cancer.

PHY34 is a synthetic small molecule, inspired by a compound naturally occurring in tropical plants of the Phyllanthus genus. PHY34 was developed to have potent in vitro and in vivo anticancer activity against high grade serous ovarian cancer (HGSOC) cells. Mechanistically, PHY34 induced apoptosis in ovarian cancer cells by late-stage autophagy inhibition.

Semisynthetic Derivatives of the Verticillin Class of Natural Products through Acylation of the C11 Hydroxy Group.

The verticillins, a class of epipolythiodioxopiperazine alkaloids (ETPs) first described 50 years ago with the discovery of verticillin A (), have gained attention due to their potent activity against cancer cells, noted both in vitro and in vivo. In this study, the complex scaffold afforded through optimized fermentation was used as a feedstock for semisynthetic efforts designed to explore the reactivity of the C11 and C11' hydroxy substituents. Functionality introduced at these positions would be expected to impact not only the potency but also the pharmacokinetic properties of the resulting compound.
