The synthesis and SAR of a new series of LXR agonist is reported. The N-Aryl-3,3,3-trifluoro-2-hydroxy-2-methyl-propionamide hits were found in a limited screen of the AstraZeneca compound collection. The effort to optimize these hits into LXRbeta selectivity is described. Compound 20 displayed desirable pharmacokinetic profile and up regulation of ABCA1(More)
Amino-2H-imidazoles are described as a new class of BACE-1 inhibitors for the treatment of Alzheimer's disease. Synthetic methods, crystal structures, and structure-activity relationships for target activity, permeability, and hERG activity are reported and discussed. Compound (S)-1m was one of the most promising compounds in this report, with high potency(More)
4-(1,3-Benzothiazol-2-yl)thiophene-2-sulfonamide (4a) was found to be a moderately potent inhibitor of cyclin-dependent kinase 5 (cdk5) from a HTS screen. The synthesis and SAR around this hit is described. The X-ray coordinates of ligand 4a with cdk5 are also reported, showing an unusual binding mode to the hinge region via a water molecule.
By use of iterative design aided by predictive models for target affinity, brain permeability, and hERG activity, novel and diverse compounds based on cyclic amidine and guanidine cores were synthesized with the goal of finding BACE-1 inhibitors as a treatment for Alzheimer's disease. Since synthesis feasibility had low priority in the design of the cores,(More)
Interstitial acidification is a hallmark of solid tumor tissues resulting from the combination of different factors, including cellular buffering systems, defective tissue perfusion and high rates of cellular metabolism. Besides contributing to tumor pathogenesis and promoting tumor progression, tumor acidosis constitutes an important intrinsic and(More)
Scoring potency is a main challenge for structure based drug design. Inductive effects of subtle variations in the ligand are not possible to accurately predict by classical computational chemistry methods. In this study, the problem of predicting potency of ligands with electronic variations participating in key interactions with the protein was addressed.(More)
In order to find optimal core structures as starting points for lead optimization, a multiparameter lead generation workflow was designed with the goal of finding BACE-1 inhibitors as a treatment for Alzheimer's disease. De novo design of core fragments was connected with three predictive in silico models addressing target affinity, permeability, and hERG(More)
The design and synthesis of a new series of c-Jun N-terminal kinase-3 (JNK3) inhibitors with selectivity against JNK1 are reported. The novel series of substituted 2'-anilino-4,4'-bipyridines were designed based on a combination of hits from high throughput screening and X-ray crystal structure information of compounds crystallized into the JNK3 ATP binding(More)
Drug resistance and therapeutic failure are important causes of disease relapse and progression and may be considered as major obstacles preventing cure of cancer patients. Tumors use a large number of molecular, biochemical and cellular mechanisms to evade chemotherapy and targeted therapy. Important determinants of drug efficacy are the intrinsic(More)
The structure-based design and synthesis of a new series of c-Jun N-terminal kinase-3 inhibitors with selectivity against JNK1 and p38alpha is reported. The novel series of substituted 6-anilinoindazoles were designed based on a combination of hits from high throughput screening and X-ray crystal structure information of the compounds crystallized into the(More)
