Small molecule purine and pseudopurine derivatives: synthesis, cytostatic evaluations and investigation of growth inhibitory effect in non-small cell lung cancer A549

Journal of Enzyme Inhibition and Medicinal Chemistry, 2018
Novel halogenated purines and pseudopurines with diverse aryl-substituted 1,2,3-triazoles were prepared. While p-(trifluoromethyl)-substituted 1,2,3-triazole in N-9 alkylated purine and 3-deazapurine was critical for strong albeit unselective activity on

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

European Journal of Organic Chemistry, EarlyView.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

Sensitive Energetics from the N‐Amination of 4‐Nitro‐1,2,3‐Triazole

ChemistryOpen, 2020
Energetic N‐amino‐C‐nitro compounds 1‐amino‐4‐nitro‐1,2,3‐triazole and 2‐amino‐4‐nitro‐1,2,3‐triazole are characterized for the first time as energetic materials. These compounds were characterized chemically by nuclear magnetic resonance (NMR), Infrared

Selective N‐Functionalization of Pyrazoles

European Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Gold(I)‐Catalyzed Annulation of Pyridines Containing Alkyne: Synthesis of N‐Alkenyl Pyridonyl Azides via Rearrangement

Journal of Heterocyclic Chemistry, EarlyView.
One‐pot gold(I)‐catalysts synthesis was developed in order to prepare N‐alkenyl 2‐pyridonyl azides. This method provides a series of N‐alkenyl 2‐pyridonyl azides in moderate to excellent yields (up to 94%). ABSTRACT A novel strategy, involving the preparation of gold‐catalyzed cyclization salts and the rearrangement of these salts in the presence of ...

A Mesoionic Platform for Persistent Anionic Nitrogen‐Centered Radicals

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Charge did not meet spin: Mesoionic 1,2,3‐triazines undergo reversible one‐electron reduction to persistent anionic nitrogen‐centered radicals. Electron paramagnetic resonance, single‐crystal x‐ray diffraction, and calculations reveal nitrogen‐localized spin and structural reorganization, while crystalline salts show clean redox cycling.

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

Medicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.
