Enantioselective Access to Trifluoromethylated Spirocyclopropyl Heterocycles

open access: yesAdvanced Science, EarlyView.
We report a rhodium‐catalyzed asymmetric [2+1] spirocyclopropanation of methylene azacycles with trifluoromethyl carbenes in situ derived from fluoroalkyl triftosylhydrazones. ABSTRACT Chiral spirocyclopropyl heterocycles have emerged as privileged three‐dimensional structural motifs in medicinal chemistry.

Photobiomodulation‑Engineered Extracellular Vesicles Enhance Neural Differentiation via UFL1‑Mediated UFMylation in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

open access: yesAdvanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

OsCPK12‐OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice

open access: yesAdvanced Science, EarlyView.
OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

Uhrf1‐Mediated PKM2 Degradation via Ubiquitination Alleviates Inflammation and Pyroptosis in Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
Uhrf1‐mediated PKM2 ubiquitination and degradation repressed the nuclear translocation of PKM2, and EPT served as a molecular glue capable of targeting the Uhrf1–PKM2 complex to alleviate the IBD course, suggesting that the Uhrf1–PKM2 axis was a previously unrecognized strategy for treating IBD.

OAF Blocks SIAH1‐Mediated Degradation of SCPX, a Therapeutic Strategy for MASLD

open access: yesAdvanced Science, EarlyView.
This study shows OAF directly binds to SCPX and inhibits its interaction with the E3 ligase SIAH1, thereby protecting SCPX from ubiquitin‐dependent degradation and stabilizing its levels. This OAF‐SCPX axis represents a novel pathway in lipid homeostasis, highlighting OAF as a promising therapeutic candidate for MASLD.
