Comparative transcriptome analysis of oil palm flowers reveals an EAR-motif-containing R2R3-MYB that modulates phenylpropene biosynthesis [PDF]

BMC Plant Biology, 2017
Background Oil palm is the most productive oil crop and the efficiency of pollination has a direct impact on the yield of oil. Pollination by wind can occur but maximal pollination is mediated by the weevil E. kamerunicus.

Comparison of the Metabolites in Fingered Citron Fruit (<i>Citrus medica</i> L. var. <i>sarcodactylis</i> Swingle) and Chayote (<i>Sechium edule</i>) Based on UPLC-Q-Orbitrap MS/MS. [PDF]

Food Sci Nutr
Untargeted UPLC‐Q‐Orbitrap MS/MS metabolomics was used to profile fingered citron (Citrus medica) from four Chinese production regions (CF1–CF4) and chayote (Sechium edule, CFM). Of 380 putatively annotated metabolites, 65 differential metabolites distinguished the five groups, clearly separating chayote from fingered citron and highlighting regional ...

Novel Sulfonium Reagents for the Modular Synthesis of Spiro[2.3]Hexanes and Heteroatom-Containing Analogues: Synthesis, Application, and Evaluation as Bioisosteres. [PDF]

Angew Chem Int Ed Engl
Strained spirocyclic spiro[2.3]hexane and its heteroatom‐containing derivatives, including previously underrepresented 5‐oxa‐1‐azaspiro[2.3]hexanes and 1,5‐diazaspiro[2.3]hexanes, were synthesized via a modular approach of insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into alkenes, carbonyls and imines.

Sub-Micromolar Inhibition of SARS-CoV-2 3CLpro by Natural Compounds

Pharmaceuticals, 2021
Inhibiting the main protease 3CLpro is the most common strategy in the search for antiviral drugs to fight the infection from SARS-CoV-2. We report that the natural compound eugenol is able to hamper in vitro the enzymatic activity of 3CLpro, the SARS ...

Boosting the Nucleophilicity of the Diphenylphosphide Anion with Crown Ether Supported Heavy Alkali Metals to Facilitate Highly Efficient Catalytic Alkene Isomerisation. [PDF]

Angew Chem Int Ed Engl
Here, we report a breakthrough study in catalytic alkene isomerisation using crown ether‐supported alkali metal phosphides in which the activity increases sequentially and significantly as Group One is descended with Cs(18‐crown‐6)PPh2 (1Cs) performing best.

An Investigation of the Storage and Biosynthesis of Phenylpropenes in Sweet Basil [PDF]

Plant Physiology, 2001
Abstract Plants that contain high concentrations of the defense compounds of the phenylpropene class (eugenol, chavicol, and their derivatives) have been recognized since antiquity as important spices for human consumption (e.g. cloves) and have high economic value.

Preparation, Encapsulation, and Performance Evaluation of Ternary Phase Change Materials for Building Envelope

Advances in Civil Engineering, 2022
Background. In order to make up for the defect that a single phase change material cannot meet the phase change temperature in a specific application field, three kinds of materials with higher phase change temperature are selected in this paper. Through
