Discovery of novel VEGFR-2 inhibitors embedding 6,7-dimethoxyquinazoline and diarylamide fragments.

VEGF/VEGFR-2 signaling plays a critical part in tumor angiogenesis. Inhibition of this pathway has been considered as a promising approach for cancer treatment. In this work, a series of 6,7-dimethoxy-4-anilinoquinazoline derivatives bearing diarylamide moiety were designed, synthesized and evaluated as potent inhibitors of VEGFR-2 kinase.

Identification of Cd-responsive RNA helicase genes and expression of a putative BnRH 24 mediated by miR158 in canola (Brassica napus).

RNA helicases play crucial roles in RNA splicing, transport, editing and degradation, protein translation initiation and siRNA-mediated gene silencing. However, knowledge about their functionality in rapeseed (Brassica napus) is rare. In the study, we identified and annotated 271 RNA helicase genes from B.
