ADP-ribosylation (ADPr) is a reversible post-translational modification of proteins, which controls major cellular and biological processes, including DNA damage repair, cell proliferation and differentiation, metabolism, stress and immune responses. In order to maintain the cellular homeostasis, diverse ADP-ribosyl transferases and
Several unnatural, predominantly hydrophobic nucleobases that pack efficiently in duplex DNA without hydrogen bonding functionalities are reported to circumvent the hydrogen bonding-based specificity, both during oligonucleotide hybridization and enzymatic DNA synthesis. The reported nucleoside analogs are efficient 'universal bases' for
A group of unnatural 1-(2-deoxy-beta-D-ribofuranosyl)isocarbostyrils having a variety of C-7 substituents [H, 4,7-(NO2)2, I, CF3, CN, (E)-CH=CH-I, -C triple bond CH, -C triple bond C-I, -C triple bond C-Br, -C=C-Me], designed as nucleoside mimics, were synthesized for evaluation as anticancer
The effect of wheat straw arabinoxylan (AX) and β-glucan stearic acid ester (SABG) composite coating on the quality and storage life of apple (Royal Delicious) was studied at 22 °C (±2) with relative humidity of 65% and 85% for 60 days.
A new isoquinolone alkaloid named 5-hydroxy-8-methoxy-4-phenylisoquinolin-1(2H)-one (3), together with two known quinolinone alkaloids 3-O-methylviridicatin (1) and viridicatol (2) were isolated from the fermentation of an endophytic fungus Penicillium sp. R22 in Nerium indicum. Their structures were elucidated by NMR, IR
