In a study aiming to determine the structural elements essential to the antifungal activity of kakuol, we synthesized a series of 2-hydroxy-4,5- methylenedioxyaryl ketones, and we assayed their in vitro antifungal activity. The most sensitive target organisms to the action of these class of compounds were Phytophthora infestans, Phytium ultimum, Cercospora beticola, Cladosporium cucumerinum, and Rhizoctonia solani. Most of the analogs showed a remarkable in vitro activity, and some of them appeared significantly more effective than the natural product. The biological activity was mainly affected by introducing structural modification on the carbonyl moiety of the natural-product molecule. In particular, compound 5a, bearing a C=C bond conjugated to the C=O group, was found active with a MIC value of 10 μg ml-1 against Cladosporium cucumerinum. The results suggest that 2-hydroxy-4,5-methylenedioxyaryl ketones can be considered promising candidates in the development of new antifungal compounds.

The mitogen-activated protein kinase (MAP) kinase 4 (MKK4) was found to be a major regulator of liver regeneration and could be a valuable drug target addressing liver related diseases by restoring its intrinsic regenerative capacity. We report on the synthesis and optimization of novel MKK4 inhibitors following a target-hopping strategy from the FDA-approved BRAFV600E inhibitor PLX4032 (8). Applying an iterative multi-parameter optimization process we carved out essential structural features yielding in compounds with a low nanomolar affinity for MKK4 and excellent selectivity profiles against the main off-targets MKK7 and JNK1, which, upon relevant inhibition, would totally abrogate the pro-regenerative effect of MKK4 inhibition, as well as against the off-targets MAP4K5, ZAK and BRAF with selectivity factors ranging from 40 to 430 for our best-balanced compounds 70 and 73.

, p. 2040 - 2047 (2020/03/13)
We report the use of a rhodium(II) dimer in visible light photoredox catalysis for the aerobic oxidation of arylboronic acids to phenols under mild conditions. Spectroscopic and computational studies indicate that the catalyst Rh2(bpy)2(OAc)4 (1) undergoes metal-metal to ligand charge transfer upon visible light irradiation, which is responsible for catalytic activity. Further reactivity studies demonstrate that 1 is a general photoredox catalyst for diverse oxidation reactions.

Microtubule has been an important target for anticancer drug development. Here we report the discovery and characterization of a series of fused 4-aryl-4H-chromene-based derivatives as highly potent microtubule inhibitors. Among a total of 37 derivatives synthesized, 23 exhibited strong in vitro anti-proliferative activities against A375 human melanoma cells. The relationship between the biological activities of these microtubule inhibitors and their chemical structure variations was analyzed. Studies of compounds 27a, 19a and 9a in parallel with colchicine as the positive control compound in a panel of biological assays revealed that these compounds blocked cell cycle progression, increased apoptosis, and inhibited HUVEC capillary tube formation at low nanomolar concentrations. The most potent compound 27a was also tested in eight additional cancer cell lines besides A375 cells and two non-cancer cells and showed potent and selective activity on these cancer cells. To understand the molecular and structure mechanism of action of these compounds, tubulin polymerization and molecular docking studies were carried out for 27a as the representative. The results were consistent with the mechanism by which 27a interacts with the colchicine binding site on tubulin and disrupts tubulin polymerization. With potent dual actions of microtubule destabilization and vascular disruption described above, this small molecule can serve as a valuable research probe of the function and role of microtubules in human diseases and promising lead for developing new therapeutic agents.

Here, biogenic synthesis of Fe2O3@SiO2 nanoparticles using fruit extract of Zanthoxylum rhetsa is reported. The SiO2 nanoparticles was synthesized using paddy straw which is a byproduct obtained in cultivation of rice. The composite was characterised by spectroscopic method like XRD, SEM, TEM and EDX analysis. The ipso-hydroxylation reactions were carried out with excellent yield within a moderate time period with mild reaction condition in all cases. Therefore, this approach may be considered as simple, easy, cheap and greener, environment friendly protocol for ipso-hydroxylation of arylboronic acids at 50 °C temperature.
