- Discovery of 2-substituted 1H-benzo[d]immidazole-4-carboxamide derivatives as novel poly(ADP-ribose)polymerase-1 inhibitors with in?vivo anti-tumor activity
-
Novel 1H-benzo[d]immidazole-4-carboxamide derivatives bearing five-membered or six-membered N-heterocyclic moieties at the 2-position were designed and synthesized as PARP-1 inhibitors. Structure-activity relationships were conducted and led to a number of potent PARP-1 inhibitors having IC50 values in the single or double digit nanomolar level. Some potent PARP-1 inhibitors also had similar inhibitory activities against PARP-2. Among all the synthesized compounds, compound 10a and 11e displayed strong potentiation effects on temozolomide (TMZ) in MX-1?cells (PF50?=?7.10, PF50?=?4.17). In?vivo tumor growth inhibition was investigated using compound 10a in combination with TMZ, and it was demonstrated that compound 10a could strongly potentiate the cytotoxicity of TMZ in MX-1 xenograft tumor model. Two co-crystal structures of compounds 11b and 15e complexed with PARP-1 were achieved and demonstrated a unique binding mode of these benzo-imidazole derivatives.

- 2-Aminomethylphenylamine as a novel scaffold for factor Xa inhibitor
-
We have been researching orally active factor Xa inhibitor for a long time. We explored the new diamine linker using effective ligands to obtain a new attractive original scaffold 2-aminomethylphenylamine derivative. Compound 1D showed very strong in vitro and in vivo factor Xa inhibitory activity, as well as favorable PK profiles in po administration to monkeys.

- Probing the subpockets of factor Xa reveals two binding modes for inhibitors based on a 2-carboxyindole scaffold: A study combining structure-activity relationship and X-ray crystallography
-
Structure-activity relationships within a series of highly potent 2-carboxyindole-based factor Xa inhibitors incorporating a neutral P1 ligand are described with particular emphasis on the structural requirements for addressing subpockets of the factor Xa enzyme. Interactions with the subpockets were probed by systematic substitution of the 2-carboxyindole scaffold, in combination with privileged P1 and P4 substituents. Combining the most favorable substituents at the indole nucleus led to the discovery of a remarkably potent factor Xa inhibitor displaying a Ki value of 0.07 nM. X-ray crystallography of inhibitors bound to factor Xa revealed substituent-dependent switching of the inhibitor binding mode and provided a rationale for the SAR obtained. These results underscore the key role played by the P1 ligand not only in determining the binding affinity of the inhibitor by direct interaction but also in modifying the binding mode of the whole scaffold, resulting in a nonlinear SAR.

- Factor Xa inhibitors based on a 2-carboxyindole scaffold: SAR of neutral P1 substituents
-
A series of novel, highly potent 2-carboxyindole-based factor Xa inhibitors is described. Structural requirements for neutral ligands, which bind in the S1 pocket of factor Xa were investigated with the 2-carboxyindole scaffold. This privileged fragment assembly approach yielded a set of equipotent, selective inhibitors with structurally diverse neutral P1 substituents.
