Biological Evaluation of Curcumin and Related Diarylheptanoids

open access: yesZeitschrift für Naturforschung C, 2006
Abstract Nine derivatives of three natural diarylheptanoids, curcumin, demethoxycurcumin and bisdemethoxycurcumin, were prepared. Their antioxidant, free radical scavenging, nitric oxide (NO) inhibitory and cytotoxic activities were evaluated and compared with those of the respective natural compounds. Curcumin (1), demethoxycurcumin (2),

Mechanochemical Hydrodeoxygenations

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using
