- Fragment-based discovery of 6-substituted isoquinolin-1-amine based ROCK-I inhibitors
-
Fragment-based NMR screening of a small literature focused library led to identification of a historical thrombin/FactorXa building block, 17A, that was found to be a ROCK-I inhibitor. In the absence of an X-ray structure, fragment growth afforded 6-substituted isoquinolin-1-amine derivatives which were profiled in the primary ROCK-I IMAP assay. Compounds 23A and 23E were selected as fragment optimized hits for further profiling. Compound 23A has similar ROCK-1 affinity, potency and cell based efficacy to the first generation ROCK inhibitors, however, it has a superior PK profile in C57 mouse. Compound 23E demonstrates the feasibility of improving ROCK-1 affinity, potency and cell based efficacy for the series, however, it has a poor PK profile relative to 23A.

- Heterocyclic derivatives and their use as antithrombotic agents
-
The present invention relates to antithrombotic compounds comprising the group Q, Q having formula (I), wherein the substructure (i) is a structure selected from (a, b and c), wherein X is O or S; X′ being independently CH or N; and m is 0, 1, 2 or 3; wherein the group Q is bound through an oxygen atom or an optionally substituted nitrogen or carbon atom, or a pharmaceutically acceptable salt thereof or a prodrug thereof. The compounds of the invention are therapeutically active and in particular are antithrombotic agents.

- 1-Aminoisoquinoline as benzamidine isoster in the design and synthesis of orally active thrombin inhibitors
-
Replacement of the highly basic benzamidine moiety of NAPAP by the moderately basic 1-aminoisoquinoline moiety resulted in thrombin inhibitors with improved selectivity towards trypsin and enhanced Caco-2 cell permeability.
