A hydrazine-free Wolff–Kishner reaction suitable for an undergraduate laboratory [PDF]

open access: yes, 2016
A Wolff–Kishner reaction that does not require hydrazine has been developed. The reaction sequence has two steps; formation of a carbomethoxyhydrazone from methyl hydrazinocarboxylate and acetophenone, then decomposition of this intermediate by treatment

Shedding Light on the D1‐Like Receptors: A Fluorescence‐Based Toolbox for Visualization of the D1 and D5 Receptors**

open access: yesChemBioChem, Volume 25, Issue 2, January 15, 2024.
We herein report the identification of UR‐NR435 (25), a SCH‐23390‐based fluorescent ligand bearing a 5‐TAMRA dye, as suitable for fluorescence microscopy at the D1R. Single‐digit nanomolar binding affinity could be determined in radioligand competition binding and molecular brightness studies at D1‐like receptors.

Inhibition of 6-hydroxydopamine-induced oxidative damage by 4,5-dihydro-3H-2-benzazepine N-oxides [PDF]

open access: yes, 2008
A number of new analogs of 3,3-dimethyl-4,5-dihydro-3H-2-benzazepine 2-oxide, structurally related to the nitrone spin trap α-phenyl-N-tert-butylnitrone (PBN), were synthesized and evaluated for their activity in vitro as protectants against oxidative ...

Preparation of substituted tetrahydro-1-benzazepines by lithiation-trapping [PDF]

open access: yes, 2018
The tetrahydro‐1‐benzazepine or benzo[b]azepine ring system is found in a number of drug molecules although methods to access 2,2‐disubstituted derivatives are rare. Here we report the preparation of N‐tert‐butoxycarbonyl‐2‐phenyltetrahydro‐1‐benzazepine

Arylbenzazepines Are Potent Modulators for the Delayed Rectifier K+ Channel: A Potential Mechanism for Their Neuroprotective Effects [PDF]

open access: yes, 2010
(±) SKF83959, like many other arylbenzazepines, elicits powerful neuroprotection in vitro and in vivo. The neuroprotective action of the compound was found to partially depend on its D1-like dopamine receptor agonistic activity. The precise mechanism for

Synthesis of Sultams from Vinyl Aziridines and 1,4-Diazabicyclo[2.2.2]octane bis(sulfur dioxide) [PDF]

open access: yes, 2020
Sultams are an important functional group found in medicinal compounds with anticancer and enzyme inhibition activity. Traditional methods for sultam synthesis often require harsh conditions and have limited substrate scope.
