Generation of the Camptothecin Scaffold by a Flavin‐Catalyzed Photooxidative Skeletal Reorganization

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
The biosynthetic pathway of the anticancer drug precursor camptothecin involves an enigmatic skeletal reorganization from a 6/5/6 tetrahydro‐β‐carboline to a 6/6/5 pyrroloquinoline ring system. Here, we show that this transformation can be achieved by photooxidation with flavin cofactors, such as flavin mononucleotide (FMN) as catalysts.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, Volume 41, Issue 10, Page 889-905, October 2026.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

A Cu‐Based Near‐IR Active MOF with an Ion‐Pair Guest Exhibiting Versatile and Selective Gas‐Solid Reactivity

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

Intravital Multimodal Imaging of Human Cortical Organoid Transplantation in a Mouse Model of Chronic Stroke

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A multimodal intravital imaging platform enables longitudinal tracking of human cortical organoids transplanted into chronic stroke lesions. By combining surgical microscopy, MRI, bioluminescence imaging, and two‐photon fluorescence microscopy, the platform captures graft placement, viability dynamics, and cellular‐scale morphology in vivo, offering a ...
