“Cut and Paste” Processes in the Search of Bioactive Products: One-Pot, Metal-free O-Radical Scission-Oxidation-Addition of C, N or P-Nucleophiles

Frontiers in Chemistry, 2022
Hypervalent iodine reagents have been applied in many metal-free, efficient synthesis of natural products and other bioactive compounds. In particular, treatment of alcohols, acetals and acids with hypervalent iodine reagents and iodine results in O ...

Antioxidant potential and iodine accumulation in tomato (Solanum lycopersicum L.) seedlings as the effect of the application of three different iodobenzoates

Folia Horticulturae, 2020
Iodine (I) has a beneficial effect on plant growth, development and antioxidant activity. The study aimed to compare iodine uptake after the application of iodobenzoates (2-iodobenzoic acid (2-IBeA), 4-iodobenzoic acid (4-IBeA) and 2,3,5-triiodobenzoic ...

Iodine(V)-Based Oxidants in Oxidation Reactions

Molecules, 2023
The chemistry of hypervalent iodine reagents has now become quite valuable due to the reactivity of these compounds under mild reaction conditions and their resemblance in chemical properties to transition metals.

Iodine Compounds and Fertilisation [PDF]

Journal of Experimental Biology, 1931
ABSTRACT In a previous paper (Carter, 1930) it was shown that the presence of thyroxine produces effects upon the oxygen consumption of suspensions of the spermatozoa of Echinus miliaris which are in some respects similar to those produced by the secretions of the eggs of the same species.

Probing key organic substances driving new particle growth initiated by iodine nucleation in coastal atmosphere [PDF]

Atmospheric Chemistry and Physics, 2020
Unlike the deep understanding of highly oxygenated organic molecules (HOMs) driving continental new particle formation (NPF), little is known about the organic compounds involved in coastal and open-ocean NPF.

Targeting EZH2 reverses thyroid cell dedifferentiation and enhances iodide uptake in anaplastic thyroid cancer

FEBS Letters, EarlyView.
Anaplastic thyroid cancer (ATC) lacks iodide uptake ability due to MAPK activation increasing the expression of the histone methyltransferase EZH2, which represses thyroid differentiation genes (TDGs) such as the sodium iodide symporter (NIS). Dual inhibition of MAPK (U0126) and EZH2 (EPZ6438/Tazemetostat) reverses this mechanism, thus restoring TDG ...
