Regiodivergent C3 and C4 Amination of Quinolines via Radical and Ionic Pathways

open access: yesAngewandte Chemie, EarlyView.
A regiodivergent strategy converts a single N‐aminoquinolinium precursor into either C3‐ or C4‐aminated quinolines. Nucleophile‐induced dearomatization diverges into light‐driven N‐centered radical capture (C3) or base‐promoted SNAr (C4), enabling rapid assembly of aminoquinoline libraries and late‐stage diversification.

Single Cell RNA Transcriptomics of Mantle Cell Lymphoma Reveals the Presence of Treatment‐Resistant Subclones at the Time of Diagnosis

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Mantle cell lymphoma (MCL) is a B‐cell malignancy with a chronically relapsing clinical course and pronounced genetic heterogeneity. To investigate the clonal dynamics underlying early disease relapse, we performed single‐cell RNA sequencing of paired tumor samples collected at diagnosis and at first relapse. Inference of copy number variants (

Bridged Pyrroloindole‐CAYC‐Gold Complexes: Harnessing Weak Secondary Intramolecular Au···H−C(sp3) Interactions in Gold(I) Catalysis

open access: yesAngewandte Chemie, EarlyView.
We present a new class of electronically and sterically hindered N‐heterocyclic carbenes, referred to as bridged cyclic (amino)ylide carbene (bCAYC), where 9H‐pyrrolo[1,2‐a]indole acted as carbene core and diaryl sulfonium as ylide partner. Corresponding bCAYC‐Au(I) exhibits a weak secondary intramolecular Au···H−C(sp3) interaction as a secondary ...

Neuropathic Pain and Enlarged Nerves in Adult Noonan Syndrome and Noonan Syndrome With Multiple Lentigines: Health‐Related Quality of Life and Neurologic Symptoms

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan syndrome (NS) and the clinically related Noonan syndrome with multiple lentigines (NSML) belong to the group of RASopathies. Although pain is not mentioned as a characteristic feature, it has recently been reported as a clinically significant problem.

Post‐ischemia and reperfusion kidney injury is mitigated in a novel complement 5 knockout rat

open access: yesPhysiological Reports
Ischemia‐reperfusion injury (IRI) is the central contributing factor to acute kidney injury (AKI). Kidney tissue that becomes necrotic during this process releases a variety of pro‐inflammatory factors, driving activation of the complement cascade ...

Scalable Access to N‑Acylindole Linkages: Enabling the Synthesis of Antitrypanosomal Noncanonical Cyclic Peptides for Chagas Disease

open access: yesAngewandte Chemie, EarlyView.
A gram‐scale supply of bulbiferamide A, which features a rare N‐acylindole linkage and possesses potent inhibitory activity against Trypanosoma cruzi epimastigotes (IC50 = 4.1 µM)—the causative parasite of Chagas disease—was successfully achieved. Moreover, the cyclization strategy developed in this study facilitated the synthesis of noncanonical ...

Bis(silylene)‐Mediated N═N Bond Scission of Diazo Compounds

open access: yesAngewandte Chemie, EarlyView.
The carborane‐based bis(silylene) enables unprecedented N═N bond scission in diazodiarylmethanes. While xanthene‐ and aniline‐based scaffolds promote end‐on addition with partial N═N activation, the carborane‐based variant uniquely achieves complete N═N bond scission of Ar2C═N═N compounds, resulting in isolable disilicon nitride imino species.

Ion‐Lock Storage With Multi‐Logic Circuitry Gated by Polar–Dipolar Interactions in Poly(Ionic Liquids)

open access: yesAngewandte Chemie, EarlyView.
Precise building block design of poly(ionic liquids) creates an opportunity to achieve ionic conductivity, energy storage, and multi‐value logic in one material while eliminating elaborate fabrication processes. ABSTRACT In these studies, we developed a new generation of polymeric materials capable of electrical energy storage and forming higher‐than ...
