Remote Amino Acid Recognition Enables Effective Hydrogen Peroxide Activation at a Manganese Oxidation Catalyst
Costas, Miquel,Olivo, Giorgio,Vicens, Laia
, (2021/12/27)
Precise delivery of a proton plays a key role in O2 activation at iron oxygenases, enabling the crucial O?O cleavage step that generates the oxidizing high-valent metal–oxo species. Such a proton is delivered by acidic residues that may either

Paragraph 0018; 0022, (2021/08/06)
The invention provides a vorinostat skeleton-based anthranilamide compound as well as preparation and application of the anthranilamide compound. The structural formula of the o-aminobenzamide compound based on a vorinostat skeleton is shown in the specification, wherein n is equal to 1-6, and R is methylamino, dimethylamino, hydroxyl, NH2 or the like. The anthranilamide compound based on the vorinostat skeleton has the effect of inhibiting gastric cancer cell proliferation through MTT method determination, and can be used for preparing anti-gastric cancer drugs.

A series of multitarget-directed ligands (MTDLs) was designed by functionalizing a pseudo-irreversible butyrylcholinesterase (BChE) inhibitor. The obtained hybrids were investigated in vitro regarding their hBChE and hAChE inhibition, their enzyme kinetics, and their antioxidant physicochemical properties (DPPH, ORAC, metal chelating). In addition, in vitro assays were applied to investigate antioxidant effects using murine hippocampal HT22 cells and immunomodulatory effects on the murine microglial N9 cell line. The MTDLs retained their antioxidative properties compared to the parent antioxidant-moieties in vitro and the inhibition of hBChE was maintained in the submicromolar range. Representative compounds were tested in a pharmacological Alzheimer's disease (AD) mouse model and demonstrated very high efficacy at doses as low as 0.1 mg/kg. The most promising compound was also tested in BChE-/- mice and showed reduced efficacy. In vivo neuroprotection by BChE inhibition can be effectively enhanced by incorporation of structurally diverse antioxidant moieties.
