Antileishmanial and Antitoxoplasmal Activities of 1,4-dihydropyridines

open access: yesACS Omega
Abstract: We have synthesized 24 1,4-dihydropyridine compounds (1,4-DHPs) with different substituents at the aromatic ring by microwave-assisted one-pot Hantzsch multicomponent reac-tion and evaluated their in vitro activities against Toxoplasma gondii and Leishmania major.

Recent Advances in Site‐ and Stereocontrolled Selective Light‐Mediated Functionalizations of Monosaccharide Derivatives

open access: yesChemPhotoChem, Volume 10, Issue 10, October 2026.
Once regarded as highly reactive and difficult‐to‐control intermediates, monosaccharide‐derived radicals have emerged as powerful tools for selective synthesis. This review highlights how modern photocatalytic strategies enable the controlled generation of these radicals and their highly regio‐ and stereoselective transformation into structurally ...

Synthesis of USP Grade [2,3,7‐13C3]‐Nicotinamide for Human Pharmacokinetic Studies

open access: yesJournal of Labelled Compounds and Radiopharmaceuticals, Volume 69, Issue 12, October 2026.
We prepared a 17.8‐g quantity of [2,3,7‐13C3]‐nicotinamide in five synthetic steps, with a 42% overall yield, and purified it to > 99% homogeneity, meeting USP standards for oral pharmaceutical dosing. This material is intended for tracking the movement and metabolism of nicotinamide through the human body.

SIRT Family: Biological Functions and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 8, August 2026.
SIRT1–SIRT7 networks from transgenic mice to human‑relevant therapeutic targets. SIRT1–SIRT7 form an isoform‑, organ‑, and disease‑specific regulatory network. Transgenic Sirt1–7 mouse models define central regulatory SIRTs (SIRT1, SIRT3, SIRT6), context‑dependent modifiers (SIRT2, SIRT4, SIRT5, SIRT7), and their key mechanisms and target organs. These
