Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

N‐Sulfonyl Azalevoglucosan: A Versatile Platform for the Synthesis of Polysubstituted Piperidines

Chemistry – A European Journal, EarlyView.
Gain by strain: The synthesis of a levoglucosan analog, in which the pyranose oxygen has been replaced by a nitrogen, allows navigation on the piperidine ring to iteratively install functional groups at C1, C2, C3, C4, and C6 positions using simple experimental protocols with minimal protecting group manipulation.

Carbonylation of silylated hydroxymethyl aziridines to beta-lactams [PDF]

, 1999
Functionalized beta-lactams are synthesized by carbonylative ring expansion of silylated hydroxymethyl aziridines catalyzed by dicobalt octacarbonyl, a process that proceeds with inversion of configuration.

Clinical Model‐Informed Precision Dosing Consult Service for Accelerating Personalized Medication in Pediatric Patients

Clinical Pharmacology &Therapeutics, EarlyView.
Traditional dosing strategies often rely on a “one‐size‐fits‐all” paradigm, assuming an “average” patient with typical demographic and pharmacological characteristics. In reality, this often overlooks existing between‐patient variability and can lead to suboptimal drug exposure or toxicity. This issue is especially pronounced in pediatric patients, who

Mechanism of activity, biosynthesis and identification of beta-lactam antimicrobial drugs

Croatian Journal of Food Science and Technology, 2011
Antimicrobal drugs are chemotherapeutics with a wide spectrum of use in human and veterinary medicine and livestock practice. Beta-lactams are the most widespread group of antimicrobal drugs and are most often used in human and veterinary medicine in the

Fecal Microbiota Transplantation and Microbiota‐Based Therapeutics in Allogeneic Hematopoietic Stem Cell Transplantation: Current Evidence and Future Directions

Clinical Pharmacology &Therapeutics, EarlyView.
The intestinal microbiome is a key regulator of immune homeostasis, metabolism, and epithelial barrier integrity. In patients with malignant hematological diseases, particularly those undergoing hematopoietic stem cell transplantation, microbiome perturbations by reduced diversity, pathobiont expansion, and loss of beneficial metabolites are common as ...

I poeti credevano nelle loro Muse? Atti della giornata di studio, Siena, 2 aprile 2003, a cura di S. Beta. [PDF]

, 2006
Nel corso dei secoli il ruolo delle Muse ha subito continue oscillazioni, passando da divine garanti dell’ispirazione artistica a figure superflue e fittizie, e viceversa. Eppure le Muse non sono sempre esistite.

Investigation of the In Vitro and In Vivo Metabolism and μ‐Opioid Receptor Affinity of the Nitazene N‐Pyrrolidino Fluetonitazene

Drug Testing and Analysis, EarlyView.
Eight metabolites for N‐pyrrolidino fluetonitazene were identified in vitro, three of which (M2, M6 and M8) were present in an authentic urine sample. M2 was the most abundant in vivo metabolite and is a common marker metabolite of nitazepyne‐type substances.

Europe's contribution to the evaluation of the use of systemic antimicrobials in the treatment of periodontitis

Periodontology 2000, EarlyView., 2023
Abstract This narrative review celebrates Europe's contribution to the current knowledge on systemically administered antimicrobials in periodontal treatment. Periodontitis is the most frequent chronic noncommunicable human disease. It is caused by dysbiotic bacterial biofilms and is commonly treated with subgingival instrumentation.
