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.

Screening Study of the Inhibitory Effects 17 Steroids on 6 Major Cytochrome P450 Isoenzymes

open access: yes, 2001
Objective: To screen the inhibitory effects of 17 steroids on 6 major cytochrome P450 (CYP) isoenzymes. Methods: The inhibitory effects of 17 steroids at 100 μM (25 μM for estrone) were tested towards 6 major CYPs including CYP1A2, CYP2A6, CYP2C9, CYP2D6,

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 ...

Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...

Metabolic Memory in Cardiovascular Disease: Encoding, Propagation, and Therapeutic Targeting

open access: yesAdvanced Science, EarlyView.
Cardiovascular risk often persists after metabolic abnormalities are corrected. This conceptual Review frames such persistence as metabolic memory, encoded through a narrowing therapeutic window from reversible marks to irreversible damage, with continuous input from peripheral organs.

Enviromics and Abiotic Enviromics: Enhancing Stress Biology and Plant Resilience Breeding

open access: yesAdvanced Science, EarlyView.
Environmental stressors are captured through high‐throughput envirotyping and integrated into an enviromic framework with genomic, transcriptomic, phenomic, and environmental data. AI/ML models enable prediction and guide marker‐assisted selection, genomic selection, genome editing, and gene pyramiding toward improved abiotic stress tolerance, yield ...
