Study acute toxicity of 4-(R-amino)-5-(thiophen-2-ylmethyl)-4H-1,2,4-triazole-3-thiol in vivo

open access: yesФармацевтичний журнал, 2018
Typically, the system is already known are used as the core for a new substance, which have already proved themselves as potential drugs. So one of these is 1,2,4-triazole ring.

Arabidopsis TRB Proteins Form Two Closely Related Complexes to Mediate H3K4me3 Demethylation and Transcriptional Repression

open access: yesAdvanced Science, EarlyView.
This study reveals that Arabidopsis telomere repeat binding proteins (TRBs) form two closely related complexes. These complexes mediate H3K4me3 demethylation and transcriptional repression through a positive feedback loop and cooperate with PEAT and PRC2 complexes to regulate multiple histone modifications and gene expression across the genome ...

Beyond Density: Unveiling the Trade‐Off in Catalytic Site Optimization Using Defect‐Engineered UiO‐66

open access: yesAdvanced Science, EarlyView.
A well‐designed experimental model reveals a trade‐off between intrinsic activity and catalytic site density in performance optimization, due to inherent diffusion resistance arising from substrate adsorption at catalytic sites. Abstract Enhancing intrinsic activity and increasing catalytic site density are two widely employed strategies to improve ...

Synthesis, physical-chemical properties and research of acute toxicity of 1,2,4-triazole derivatives containing thiophene core

open access: yesAktualʹnì Pitannâ Farmacevtičnoï ì Medičnoï Nauki ta Praktiki, 2015
The aim of research. Modern drugs must have certain characteristics, such as low toxicity and high efficiency. Special attention should be given to esthers of 2-(1,2,4-triazoles-3-iltio)acetic acids.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

open access: yesAdvanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Cupin‐Type Dimethylsulfoniopropionate Lyase from Pelagibacter ubique (DddKPu) Catalyzes Aza‐Michael Addition of Primary and Secondary Amines to Acrylic Acid

open access: yesAngewandte Chemie, EarlyView.
A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.
