An expedient synthesis of honokiol and its analogues as potential neuropreventive agents
摘要:
An efficient synthesis of honokiol with Suzuki-Miyaura cross coupling obtained an overall yield of 45%. The proposed approach successfully synthesized several structurally similar alkyl, alkenyl and alkynyl analogues, seven of which showed potential neuropreventive activity against MPP+-induced and CHP/TBHP oxidative stress induced neuroblastoma cell death.

rearrangement, a wide range of aromaticamides react smoothly with arylboron reagents, affording a series of biologically relevant diarylmethylamines as deoxygenative C−C bond cross-coupling products. With its simplicity and versatility, this reaction shows great promise in the synthesis of amines from amides, which may open up new avenues in retrosynthetic planning and find widespread use in academia
Flipping disc networks: A discotic star shaped mesogen decorated with three DNA bases thymine reversibly switches between a columnar and an extraordinary bicontinuous cubic network. The double nanosegregated bicontinuous structure is stabilized by self-association of hydrogen bonding thymines and realize a 3D charge transport. A phase flipping is also discerned by the addition of adenine as complementary
翻转盘网络:用三个 DNA 碱基胸腺嘧啶装饰的盘状星形介晶可在柱状和非凡的双连续立方网络之间可逆地切换。双纳米分离的双连续结构通过氢键胸腺嘧啶的自缔合而稳定,并实现3D电荷传输。还可以通过添加腺嘌呤作为互补碱基来识别相翻转。
