Dissimilar Reactions and Enzymes for Psilocybin Biosynthesis in Inocybe and Psilocybe Mushrooms

Angewandte Chemie International Edition, EarlyView.
Mushrooms have learned twice independently how to make the iconic magic mushroom natural product psilocybin. This article introduces the enzymes of the second pathway, found in a fiber cap mushroom. Curiously, the two pathways do not share any reaction, nor do the enzymes show a close relationship, but both pathways proceed via 4‐hydroxytryptamine as a

Identification of a Proteolysis‐Targeting‐Chimera that Addresses Activated Checkpoint Kinase‐1 Reveals its Non‐Catalytic Functions in Tumor Cells

Angewandte Chemie International Edition, EarlyView.
In cancer cells, the induction of DNA replication stress by HU activates CHK1 by autophosphorylation. This leads to cell cycle arrest and recruits the DNA repair protein WRN to promote DNA repair and cell survival. In such cells, addition of the CHK1 inhibitor 9a propels DNA damage and apoptosis.

Interplay of Polar Order and Positional Order in Liquid Crystals–Observation of Re‐entrant Ferroelectric Nematic Phase

Angewandte Chemie International Edition, EarlyView.
In most systems the degree of order increases monotonically with decreasing temperature. Here we report that due to unfavourable dipole interactions within the smectic layers, the lamellar structure of a liquid crystal may be spontaneously destroyed by the development of polar, ferroelectric order.
