Review Article: The Impact of the Gut Microbiome on Ulcerative Colitis Pharmacotherapy

Alimentary Pharmacology &Therapeutics, EarlyView.
The gut microbiome modulates ulcerative colitis pharmacotherapy through microbial drug metabolism, immune regulation and altered drug bioavailability. Microbial composition influences response to aminosalicylates, corticosteroids, immunomodulators, biologics and small molecules, while microbiome‐targeted therapies show emerging promise.

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

Recent Advances in Fluorescent Probes for Imaging Enzyme Activity in NETosis

ChemBioChem, Volume 27, Issue 15, 14 August 2026.
Fluorescent probes enable real‐time visualization of neutrophil effector functions. This review summarizes current probe design strategies and emerging tools for imaging key enzymatic activities, with emphasis on mechanisms underlying NETosis, a lytic form of neutrophil extracellular trap (NET) formation. We discuss current limitations, challenges, and

Structure‐Based Design, Synthesis, and Biological Evaluation of Oxadiazole–Morpholine Hybrids as Potent PARP‐1 Inhibitors Inducing Apoptosis in Breast Cancer Cells

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT Poly(ADP‐ribose) polymerase‐1 (PARP‐1) plays a central role in the repair of DNA single‐strand breaks and represents an established therapeutic target in cancer treatment. In this study, a series of novel oxadiazole–morpholine hybrid compounds was designed and synthesized using a structure‐based drug design approach to target the catalytic ...
