Manganese carbonyl-mediated reactions of azabutadienes with phenylacetylene, methyl acrylate and other unsaturated molecules [PDF]
Reaction of PhCH₂Mn(CO)₅ with l,4-di-aryl-1-aza-1,3-butadienes gave substituted pyrrolinonyl rings which were η⁴-coordinated to a Mn(CO)₃ group. These are formed by intramolecular CO insertion into a (non-isolated) cyclomanganated intermediate, followed ...

Design, Synthesis, and Anticancer Activity Studies of Novel Quinoline-Chalcone Derivatives
The chalcone and quinoline scaffolds are frequently utilized to design novel anticancer agents. As the continuation of our work on effective anticancer agents, we assumed that linking chalcone fragment to the quinoline scaffold through the principle of ...

Inhibition of Hedgehog-dependent tumors and cancer stem cells by a newly identified naturally occurring chemotype [PDF]
Hedgehog (Hh) inhibitors have emerged as valid tools in the treatment of a wide range of cancers. Indeed, aberrant activation of the Hh pathway occurring either by ligand-dependent or -independent mechanisms is a key driver in tumorigenesis.

In maize, the bHLH transcription factor ZmbHLH118 directly binds to the promoter of ZmCLCa and inhibits its expression. Tonoplast‐localized ZmCLCa mediates NO3− influx into the vacuole to regulate intracellular NO3− homeostasis, modulating nitrate uptake and metabolism, plant growth, and grain yield.

Pro-Angiogenic Effects of Chalcone Derivatives in Zebrafish Embryos in Vivo
The aim of this study was to investigate novel chalcones with potent angiogenic activities in vivo. Chalcone-based derivatives were evaluated using a transgenic zebrafish line with fluorescent vessels to real-time monitor the effect on angiogenesis ...

Thermal study of chalcones [PDF]
Chalcones α-β-unsaturated ketones are found in large plant species. Synthesis of chalcones and its three analogues hydroxy group at 2′, 3′ and 4′ positions (2–4) was carried out. The studies of thermal behavior were made by thermogravimetry (TG) and differential scanning calorimetry, both under oxygen and nitrogen purge gases.

Effects of Polyphenols on Oxidative Stress-Mediated Injury in Cardiomyocytes [PDF]
Cardiovascular diseases are the main cause of mortality and morbidity in the world. Hypertension, ischemia/reperfusion, diabetes and anti-cancer drugs contribute to heart failure through oxidative and nitrosative stresses which cause cardiomyocytes ...
