The Synthesis and Biological Activity of 1-Alkyl-4-(3-azacyclobenzoyl)-5-hydroxypyrazole Herbicides

open access: yesCHIMIA, 2003
The benzoylpyrazoles belong to a class of herbicides that inhibit the enzyme 4-hydroxy-phenylpyruvate dioxygenase (HPPD). This mode of action is characterized by bleaching due to the disruption of plastoquinone and ?-tocopherol biosynthesis ...

Emerging Strategies for Platelet‐Modified Nanoparticles in Targeted Tumor Therapy

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review highlights innovative strategies using platelet‐modified nanoparticles to target tumors more precisely. By mimicking platelet functions, these biomimetic carriers improve tumor homing, enhance drug delivery, and reduce immune clearance.

Experimentally Guided Iterative Parameter Estimation for Predictive Chemical Oscillator Models

open access: yesAngewandte Chemie, EarlyView.
We present an iterative, experimentally guided parameter estimation method to improve the predictivity of chemical oscillator models. This method enables the efficient identification of sustained oscillations in the Fmoc oscillator across diverse conditions.

Diels-alder cycloaddition in the synthesis of 1-azafagomine, analogs, and derivatives as glycosidase inhibitors [PDF]

open access: yes, 2012
This comprehensive review deals with the synthesis of 1-azafagomine, analogs, and derivatives having the Diels-Alder cycloaddition as the key step. Most of the compounds referred are racemic or have been resolved by lipase transesterification.

Design and synthesis of a fragment set based on twisted bicyclic lactams

open access: yes, 2018
Current fragment sets tend to be dominated by flatter molecules, and their shape diversity does not reflect that of the fragments that are theoretically possible.

A nongenomic mechanism for progesterone-mediated immunosuppression: Inhibition of K+ channels, Ca2+ signaling, and gene expression in T lymphocytes [PDF]

open access: yes, 1998
The mechanism by which progesterone causes localized suppression of the immune response during pregnancy has remained elusive. Using human T lymphocytes and T cell lines, we show that progesterone, at concentrations found in the placenta, rapidly and ...

1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones [PDF]

open access: yes, 2010
1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones is described. A series of novel isoxazolines are isolated from the nitrile oxide cycloadditions, whilst the isoxazolines generated from the nitrone cycloadditions ...
