Selective small molecule inhibitors of the potential breast cancer marker, human arylamine N-acetyltransferase 1, and its murine homologue, mouse arylamine N-acetyltransferase 2
摘要:
The identification, synthesis and evaluation of a series of rhodanine and thiazolidin-2,4-dione derivatives as selective inhibitors of human arylamine N-acetyltransferase 1 and mouse arylamine N-acetyltransferase 2 is described. The most potent inhibitors identified have submicromolar activity and inhibit both the recombinant proteins and human NAT1 in ZR-75 cell lysates in a competitive manner. H-1 NMR studies on purified mouse Nat2 demonstrate that the inhibitors bind within the putative active site of the enzyme. (C) 2008 Elsevier Ltd. All rights reserved.

Chemiluminescent compositions, methods, assays and kits for oxidative enzymes are described. Further disclosed are dioxetane compounds of the form:
where R can independently be any branched alkyl or cycloalkyl group which provides stabilization for the dioxetane or where both R groups together form a cycloalkyl or polycycloalkyl moiety spiro bound to the dioxetane ring, wherein each R group or the spiro bound moiety can be unsubstituted or substituted with one or more electron-withdrawing groups or electron donating groups, or groups providing preferential oxidative isozyme substrate recognition, and wherein R
1
is an aryl group, or an alkyl group of 1-20 carbon atoms, which can be optionally substituted with 1 or more halogen atoms, and wherein T is an aryl or heteroaryl ring capable of emitting light upon enzyme activated decomposition of the dioxetane I.
Kits, methods and assays are also disclosed that comprise the dioxetane compounds.
