B12‐Cofactor Inactivation by Cobalt to Rhodium Mutation in Methylrhodibalamin: An Antivitamin B12 and Antibiotic

open access: yesChemistryEurope, EarlyView.
Replacement of cobalt in the organometallic B12‐cofactor methylcobalamin (MeCbl) by rhodium furnishes a structural mimic with a significantly stronger metal–carbon bond. This synthetically challenging formal metal‐mutation converts the naturally optimized biological methyl‐transfer catalyst MeCbl into a designed antivitamin B12, an inactivated B12 ...

Nitration of GlcCer and Related Complex Lipids Enhances CD1d Binding Affinity and Modulates Immune Responses via Lipid Antigen Presentation to Natural Killer T Cells

open access: yesChemistryEurope, EarlyView.
Nitration of glycolipids and phospholipids increases their binding to CD1d. Nitrated β‐GlcCer and phospholipids show strong CD1d binding but induce minimal cytokine production, suggesting potential immune suppression. In contrast, nitrated endogenous‐type α‐GalCer enhances cytokine responses, indicating that nitrated lipids can modulate CD1d‐mediated ...

Advancing Predictions of Oral Drug Absorption, CYP3A4 Induction, and Transporter‐Mediated Interactions Using a Human Primary Intestinal 3D Model (EpiIntestinal™)

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Accurate prediction of oral drug absorption in humans is essential for early drug development; however, physiologically relevant human models are lacking. This study aims to comprehensively assess the EpiIntestinal™, a human primary intestinal 3D model, for its ability to predict oral absorption (Fa), intestinal availability (Fg), CYP3A4 induction, and
