Resurrected Ancestral Cannabis Enzymes Unveil the Origin and Functional Evolution of Cannabinoid Synthases

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cannabinoids, such as tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA) and cannabichromenic acid (CBCA), are bioactive and medicinally relevant compounds found in the cannabis plant (Cannabis sativa L.). These three compounds are synthesised from a single precursor, cannabigerolic acid (CBGA), through regioselective reactions ...

Facile Bottom‐Up Assembly of Photonic Micropatterns via Surface‐Guided Colloidal Crystallization

Advanced Materials, Volume 38, Issue 7, 2 February 2026.
High‐resolution photonic micropatterns with vivid structural colors are fabricated through bottom‐up assembly, guided by surface‐dependent regioselective heterogeneous nucleation and crystal growth of colloidal particles. Full‐spectrum color tunability is achieved by controlling particle size and interparticle attraction, while in situ color mixing is ...

Biocatalytic Synthesis of Diamondoid Diols by the Brown‐Rot Fungus Wolfiporia cocos

ChemBioChem, Volume 27, Issue 3, February 2026.
Wolfiporia cocos cultures were tested for CH‐oxidative activity using rigid diamondoid substrates. Adamantane derivatives gave typical diols similar to known chemical oxidations, while diamantane‐4‐ol showed unusual selectivity, forming rare 4,9‐ and 1,9‐diols.

Further Insights Into the Metabolism of LGD‐4033 in Human Urine. Part 1. Structure Elucidation of Additional Important Metabolites

Drug Testing and Analysis, Volume 18, Issue 2, Page 245-259, February 2026.
Well‐characterized, chemically synthesized molecules related to LGD‐4033 metabolism were used as analytical standards for the analysis of LGD‐4033 post‐administration urine samples. This approach offered further insights into LGD‐4033 metabolism, providing solid experimental proof for the structure of important previously reported metabolites and ...

Asymmetric Hydride Shift Reactions Catalyzed by Chiral Aluminium Complexes

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
An asymmetric intramolecular hydride shift reaction has been developed that is catalyzed by Al Lewis acids in conjunction with a chiral BINOL‐derived ligand. Racemic THP substrates are transformed into cyclohexene products via an intermediate prochiral enone; which undergoes a key 1,5‐hydride shift reaction.
