Phosphoryl Radicals from Trivalent Iminyl Phosphines: A Photocatalytic Approach to N‐Phosphoryl Azetidines

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Photochemically generated phosphoryl radicals from iminyl phosphines enable strain‐release addition to azabicyclobutanes, providing access to elusive N‐phosphoryl azetidines. Combined experimental, computational, and EPR studies reveal an unconventional water‐assisted photoredox pathway.

Azetidine, pyrrolidine and hexamethyleneimine at 170 K [PDF]

open access: yesActa Crystallographica Section C Crystal Structure Communications, 2008
The crystal structures of the cyclic amines azetidine (C(3)H(7)N), pyrrolidine (C(4)H(9)N) and hexamethyleneimine (homopiperidine, C(6)H(13)N), of the series (CH(2))(n)NH, with n = 3, 4 and 6, respectively, have been determined at 170 K, following in situ crystallization from the melt.

Strain Release of 1‐Azabicyclo[1.1.0]butanes as a Gateway to Highly Functionalized Azetidines: New Strategies and Structural Motifs

open access: yesChemistry – A European Journal, EarlyView.
Over the past decade, the interest in azetidines has continuously risen, by virtue of their highly appealing pharmaceutical properties. Monocyclic, spirocyclic, and bridged azetidines can be accessed by leveraging 1‐azabicyclo[1.1.0]butanes as precursors.

Dapagliflozin alleviates high‐fat‐induced obesity cardiomyopathy by inhibiting ferroptosis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1358-1373, April 2025.
Abstract Aim: Dapagliflozin (Dapa) is a novel hypoglycaemic agent with multiple cardiovascular protective effects, and it is widely used in treatment of heart failure patients, but whether it can improve obese phenotype of heart failure and its mechanism is still unclear.

Chemoproteomic discovery of a brain‐penetrant, covalent NLRP3 inhibitor that binds a novel allosteric pocket

open access: yesBritish Journal of Pharmacology, EarlyView.
NLRP3 is a promising inflammatory target, but existing inhibitors lack diversity and brain penetrance, and none are approved. Using chemoproteomics, we discovered a novel series that binds to Cys463 in a previously uncharacterized pocket. Compounds showed nanomolar potency, brain exposure, and in vivo suppression of IL‐1β, supporting neuroinflammatory ...

Organocatalyzed asymmetric [2+2] cycloaddition of saccharin-derived endocyclic ketimines and allenoates for the synthesis of fused azetidines

open access: yesTetrahedron Chem
We report a novel enantioselective [2 + 2] cycloaddition of allenoate and endocyclic ketimine derived from saccharin, catalyzed by a chiral tertiary amine.

Transgenic selection and underlying mechanisms in apicomplexan parasites

open access: yesThe FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Actinomycin Derivatives: Structural Diversification and Biological Activities

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

S‐Adenosyl‐d‐Methionine as a Non‐Physiological Substrate for a Wide Range of SAM‐Dependent Enzymes

open access: yesChemBioChem, Volume 27, Issue 14, 29 July 2026.
From methylation and cyclisation to radical chemistry, diverse enzyme classes utilise the non‐canonical cofactor d‐SAM. These findings reveal an unexpected tolerance of SAM‐dependent catalysis towards inversion of the methionine Cα stereocentre. The ability of SAM‐dependent enzymes to accept S‐adenosyl‐d‐methionine [d‐SAM, (SS,RCα)‐SAM] instead of the ...
