Alkylated Piperazines and Piperazine-Azole Hybrids as Antifungal Agents [PDF]

Journal of Medicinal Chemistry, 2017
The extensive use of fluconazole (FLC) and other azole drugs has caused the emergence and rise of azole-resistant fungi. The fungistatic nature of FLC in combination with toxicity concerns have resulted in an increased demand for new azole antifungal agents.

Piperazine-fused cyclic disulfides: high-performance bioreduction-activated cores for bifunctional probes and reagents

, 2023
We report piperazine-fused six-membered-cyclic dichalcogenides as rapid-response redox substrates that interface with thiol/disulfide redox biology. Combining the stability of 1,2-dithianes with unprecedentedly rapid kinetics of self-immolation after ...

Spatiotemporal Control of Formation of Dynamic Protein Fiber Assemblies via Photophysical Effects of a Focused Laser Beam

Advanced Science, EarlyView.
Tightly focused laser irradiation can accumulate tubulin proteins at/around the laser focus, which leads to the formation of highly ordered microtubule assemblies. The assemblies can exhibit various dynamic behaviors such as radial motion, bundling, and flagella‐like rotation with motor protein and chemical energy, highlighting as a unique tool for ...

Piperazine-2,3,5,6-tetraone [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
The mol-ecule of the title compound, C(4)H(2)N(2)O(4), is located around an inversion center and the four O atoms are in the 2,3,5,6-positions of the piperazine ring. In the crystal, bifurcated N-H⋯O hydrogen bonds link the mol-ecules into a corrugated layer parallel to (101).

Understanding the Catalytic Determinant role of Diaphorase‐Like Subunit in Formate Dehydrogenases via Redox Couples

Advanced Science, EarlyView.
A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...

Synthesis and Evaluation of Novel Cinnamic Acid Hybrids With Antiacetylcholinesterase, Antioxidant, and Anti-Inflammatory Properties. [PDF]

ChemMedChem
In this work, we identified two novel pleiotropic sinapic acid derivatives with excellent anti‐acetylcholinesterase, antioxidant, and anti‐inflammatory properties. Alzheimer's disease, one of the most widespread neurodegenerative disorders, is known for its multifactorial nature that makes it challenging to treat.
