Cucurbit[7]uril‐Styryl Dye Complexes for Fluorescent Recognition of DNA and Cell Imaging

ChemBioChem, EarlyView.
Recognition properties in solution and in cancer cells: a two dicationic cyanine dyes with different functionalities were developed and studied for their fluorescent properties, cytotoxicity and cellular imaging. The effect of encapsulation was checked using synthetic molecular container of cucurbit[7]uril.

Impact of Mutational Status on Intracellular Effects of Cell‐Permeable CaaX Peptides in Pancreatic Cancer Cells

ChemBioChem, EarlyView.
This work deals with intracellular effects of cell‐permeable CaaX‐peptides, designed to influence prenylated proteins like KRas. The results show that after CaaX‐1 treatment, not only KRas expression and signaling are specifically altered in mutated pancreatic cancer cells, but also plasma membrane localization of KRas is affected.

A Bacterial Sulfotransferase Catalyzes an Unusual Di‐Sulfation in Natural Products Biosynthesis

ChemBioChem, EarlyView.
Herein, a unique sulfotransferase, AdpST, is identified from the adp biosynthetic gene clusters (BGC) in Streptomyces davaonensis DSM101723 and demonstrates that AdpST possesses di‐sulfation activity, which is unprecedented for bacterial phosphoadenosine‐5’‐phosphosulfate (PAPS)‐dependent sulfotransferases. It is further shown that the adp BGC contains

Lienhwalides: Unique Tropolone–Maleidride Hybrids from Hypoxylon lienhwacheense

ChemBioChem, EarlyView.
Lienhwalides are novel tropolone–maleidride hybrid molecules unique in nature. Absolute configuration is solved by semisynthetic approaches and X‐ray analysis. Interplay between both lwt and lwm biosynthetic gene clusters is responsible for the production of lienhwalides.
