KDR kinase inhibition is considered to play an important role in regulating angiogenesis, which is vital for the survival and proliferation of tumor cells. Recently we disclosed a structure-based kinase inhibitor design strategy which led to the identification of a new class of VEGFR-2/KDR kinase inhibitors bearing heterocyclic substituted pyrazolones as the core template. Instability in a rat S9 preparation and poor iv PK profiles for most of these inhibitors necessitated exploration of new pyrazolones to identify new analogs with improved metabolic stability. Optimization of the heterocyclic moiety led to the identification of the thiadiazole series of pyrazolones (D) as potent VEGFR-2/KDR kinase inhibitors. SAR modifications, kinase selectivity profiling, and structural elements for improved PK properties were explored. Oral bioavailability up to 29% was achieved in the rat. Modeling results based on the Glide XP docking approach supported our postulation regarding the interaction of the lactam segment of the pyrazolones with the hinge region of the KDR kinase.

Pharmacologically active compounds corresponding to the general formula I STR1 in which R1 represents hydrogen, a lower alkyl or cycloalkyl-alkyl group or an optionally substituted phenyl-lower alkyl group, R2 denotes hydrogen or a lower alkyl group optionally substituted in the α-position to the nitrogen atom by lower alkoxy, R3 denotes hydrogen, lower alkyl, lower alkoxy, halogen or hydroxyl, n represents 1 or, if the --(CH2)n -- chain is in the 4-position of the ring structure, also represents 2, R4 denotes hydrogen, lower alkyl, cycloalkyl, cycloalkyl-lower alkyl or an optionally substituted phenyl-lower alkyl group, and R5 denotes hydrogen, lower alkyl, cycloalkyl, cycloalkyl-lower alkyl or an optionally substituted phenyl-lower alkyl group, or R4 and R5, together with the nitrogen atom to which they are bonded, form a heterocycle and D represents a bond, or, if R4 and R5 do not denote hydrogen, also represents the --N=CH-- group, and their physiologically acceptable acid addition salts are described, and also processes and intermediates for their preparation.
