The design and synthesis of novel inhibitors of NADH:ubiquinone oxidoreductase
摘要:
Potent new inhibitors of NADH:ubiquinone oxidoreductase (complex 1) have been designed, with the help of molecular modelling, by hybridisation of known complex I inhibitors with inhibitors of cytochrome c oxidoreductase. The most interesting compound was the chromone 7 which was a selective inhibitor of complex I (IC50 15 nM) and showed acaricidal activity against spider mites. (C) 2003 Elsevier Ltd.

The present disclosure relates to reagents and method for performing trifluoromethylation, difluoromethylation or alkylation of aromatic or heteroaromatic rings in a redox-neutral manner without any catalyst which are enabled by light. In addition, there are methods for synthesizing the starting reagents used in the trifluoromethylation, difluoromethylation or alkylation reactions.
The present disclosure is directed, in part, to compounds and methods for imaging myocardial perfusion, comprising administering to a patient a contrast agent which comprises a compound that binds MC-1, and an imaging moiety, and scanning the patient using diagnostic imaging.

Squalene-hopene cyclase (SHC) is a useful model enzyme for predicting molecular interactions with oxidosqualene cyclase (OSC). Structure–activity relationships were investigated for numerous coumarin-derived inhibitors of SHC, and structural simplifications are suggested. Both umbelliferone and 2,4-dihydroxyacetophenone provide convenient starting nuclei for the design of SHC inhibitors. Derivatives bearing an ω-epoxyfarnesyl moiety or just a plain alkyl chain showed an inhibitory effect on a recombinant SHC from Alicyclobacillus acidocaldarius expressed in Escherichia coli.
