The present invention relates to pyrimidine derivatives of Formula (Ia) and (Ib) (including tautomers, isomers, prodrugs, and pharmaceutically acceptable salts thereof). Said compounds are useful in the treatment of pain (such as neuropathic pain), inflammation, and epilepsy (by acting as anticonvulsants). Methods of medical treatment making use of said compounds, as well as additional compounds of Formula (IIa) and (IIb), are also disclosed.

High-throughput screening has identified a novel class of inhibitors of the checkpoint kinase Wee1, which have potential for use in cancer chemotherapy. These inhibitors are based on a 4-phenylpyrrolo[3,4-c]-carbazole-1,3(2H,6H)- dione template and have been shown by X-ray crystallography to bind at the ATP site of the enzyme. An extensive study of the effects of substitution around this template has been carried out, which has identified substituents which lead to improvements in potency and selectivity for Wee1. While retention of the maleimide ring and pendant 4-phenyl group is necessary for potency, replacement of the carbazole nitrogen by oxygen is well tolerated and results in improved Wee1 selectivity against the related checkpoint kinase Chk1. Wee1 potency and selectivity are also enhanced by the incorporation of lipophilic functionality at the 2′-position of the 4-phenyl ring, and Wee1 selectivity against Chk1 is favored by C3-C5 alkyl substitution of the carbazole nitrogen. These studies provide a basis for the design of active analogues of the pyrrolocarbazole lead with improved physical properties.
