Dormancy Patterns of Apple Trees Grown in a Mild Winter Region: A Breakpoint Model Analysis
ABSTRACT Climate change poses a significant challenge to the production of temperate climate fruit trees, since the dormancy of these species is regulated by the chill and heat accumulation during winter and early spring. This study aimed to identify the dormancy evolution patterns of three apple cultivars (“Galaxy,” “Fuji Suprema,” and “Eva”) in a ...

Prebiotic Organic Chemistry of Diketopiperazines
Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

The main urinary metabolite of hydrogen cyanamide (syn.: cyanamide) in rat and man is acetylcyanamide (syn.: N-acetylcyanamide). An analytical method was developed to determine acetylcyanamide in the urine with a limit of quantification of <10 μg/l

We report a biosynthesis‐inspired ring distortion approach that involves oxidative ring cleavage, ring rearrangement, and ring expansion reactions from a diverse collection of indole alkaloids and derivatives. This chemical synthesis approach led to the synthesis of >25 distinct chemotypes from 14 indole alkaloids.

DFT and TST Study of the Calcium Cyanamide Process for Synthesizing Cyanamide and Dicyandiamide
Exploring the microscopic reaction mechanism of dicyandiamide (DCD) synthesis using calcium cyanamide (CaCN2) is highly desirable because of the low conversion of reactants and selectivity of DCD products.
