The reaction of substituted ethylenediamines with various fumarates, maleates, and maleimides to form substituted ketopiperazine aceticacidesters and amides was investigated. This method affords a straightforward, high yield approach to a variety of potential peptidomimetics and can yield surprising results with regard to regio- and stereoselectivity.

This invention provides bicyclic heterocycles that are useful for treating cell proliferative disorders, such as cancer and restenosis, as well as angiogenesis and atherosclerosis. We have now discovered a group of bicyclic compounds that are potent inhibitors of cyclin-dependent kinases (cdks), growth factor-mediated kinases, and non-receptor kinases. The compounds are readily synthesized and can be administered by a variety of routes, including orally, and have sufficient bioavailability for clinical use. This invention provides compounds of Formula I:
1
where
Z is N or CH;
G is N or CH;
W is NH, S, SO, or SO
2
,
R
1
includes phenyl and substituted phenyl,
R
2
includes alkyl and cycloalkyl,
R
3
includes alkyl and hydrogen,
R
8
and R
9
include hydrogen and alkyl, and the pharmaceutically acceptable salts thereof.
This invention also provides pharmaceutical formulations comprising a compound of Formula I together with a pharmaceutically acceptable carrier, diluent, or excipient therefor.
