    On a Possible Neutral Charge State for the Catalytic Dyad in β-Secretase When Bound to Hydroxyethylene Transition State Analogue Inhibitors
    摘要:
    beta-Secretase is one of the aspartic proteases involved in the formation of amyloid plaques in Alzheimer's disease patients Our previous results using a combination of surface plasmon resonance experiments with molecular Modeling calculations: suggested that the Asp dyad in beta-secretase bound to hydroxylethylene containing inhibitors adopts a neutral charged state. In this work, we show that the Asp dyad diprotonated state reproduced the binding ranking of a set of these inhibitors better than alternative protonation states.

    pyrrolidin-3-ol alkaloid. This work reports the first enantioselective synthesis of putative asperidine B and its desmethyl analogue via a chiron approach starting from d-isoascorbic acid as well as evaluation of their free-radical scavenging, antidiabetic, and anti-hyperlipidemic activities. Both putative asperidine B and its desmethyl analogue markedly reduced the total reactive oxygen species (ROS) without

    Dibenzyl-3'-O-[(6-azido-2,3,6-trideoxy-4,5-di-O-benzyl) hexanoyl] thymidine 5'-yl phosphate 8a was prepared. Catalytic hydrogenolysis removed only the benzyl esters and reduced the azido group. When the benzyl ethers were replaced by p-phenylbenzyl or allyl ethers, their deprotection also failed.
