Marine natural products show a large variety of unique chemical structures and potent biological activities. Elucidating the target molecule and the mechanism of action is an essential and challenging step in drug development starting with a natural product. Odoamide, a member of aurilide-family isolated from Okinawan marine cyanobacterium, has been known to exhibit highly potent cytotoxicity against various cancer cell lines.

Background: CRISPRi screening has become a powerful approach for functional genomic research. However, the off-target effects resulting from the mismatch tolerance between sgRNAs and their intended targets is a primary concern in CRISPRi applications.
Results: We introduce Guide Library Designer (GLiDe), a web-based tool specifically created for the genome-scale design of sgRNA libraries tailored for CRISPRi screening in prokaryotic organisms.
The Asgard archaeal ESCRT-III system forms helical filaments and remodels eukaryotic-like membranes.

The ESCRT machinery mediates membrane remodeling in numerous processes in cells including cell division and nuclear membrane reformation. The identification of ESCRT homologs in Asgard archaea, currently considered the closest prokaryotic relative of eukaryotes, implies a role for ESCRTs in the membrane remodeling processes that occurred during eukaryogenesis. Yet, the function of these distant ESCRT homologs is mostly unresolved.

Aromatic π-complexes play a significant role in various chemical and biological systems, significantly influencing their physico-chemical and spectroscopic properties. The identification of new compounds capable of π-complex formation is therefore of great interest. The paper investigates the fluorescent properties of 1,5-diisocyanonaphthalene (1,5-DIN) in different aromatic solvents, demonstrating its potential for distinguishing between aromatics based on emission spectra.

Electrochemical reduction of carbon dioxide (CO) into sustainable fuels and base chemicals requires precise control over and understanding of activity, selectivity and stability descriptors of the electrocatalyst under operation. Identification of the active phase under working conditions, but also deactivation factors after prolonged operation, are of the utmost importance to further improve electrocatalysts for electrochemical CO conversion. Here, we present a multiscale in situ investigation of activation and deactivation pathways of oxide-derived copper electrocatalysts under CO reduction conditions.
