Discovery of highly potent Src SH2 binders: Structure–activity studies and X-ray structures
摘要:
Optimization of the hydrophobic moiety of caprolactam/thiazepinone based compounds led to the identification of potent Src SH2 binders in two different series incorporating a phosphotyrosine group (RU 81843) or a phosphobenzoic group (RU 79181). The X-ray co-structures with the Src SH2 domain revealed different binding modes for RU 81843 and RU 79181, and an excellent fit between RU81843 and the Src SH2 protein thus explaining its high potency (9 nM, 15-fold more potent than pYEE1 reference peptide).

The present invention relates to interleukin - Iβ converting enzyme inhibitors
of formula I: wherein each X is independently selected from: i) -C(W)2-;
ii) -C(O)-; iii) -NR2-; iv) -S-; v) -S(O)-; vi) -S(O)2-;
vii) two units, one from each adjacent X unit, can be taken together to form a substituted
or unsubstituted double bond having the formula -CW=CW-; wherein
each W is hydrogen of a unit having the formula -(L2)j-R2,
the index j is 0 or 1;R is a carbocyclic or heterocyclic aryl ring; R1
is a cysteine trap; each R2 is independently a suitable substituent;
and L, L1, and L2 are linking units.

A series of monocyclic thiazepine inhibitors of interleukin-1 beta converting enzyme (ICE) were synthesized in eight steps from commercially available intermediates. In vitro biological evaluation showed the thiazepines to be moderately potent ICE inhibitors, with the most active compound exhibiting an IC50 value of 30 nM in an enzyme inhibition assay. Compounds of this class possessed good selectivity against the related enzymes caspase-3 and caspase-8. (c) 2006 Elsevier Ltd. All rights reserved.
