A novel series of CHK1 inhibitors with a distinctive hinge binding mode, exemplified by 2-aryl-N-(2-(piperazin-1-yl)phenyl)thiazole-4-carboxamide, was discovered through high-throughput screening using the affinity selection-mass spectrometry (AS-MS)-based Automated Ligand Identification System (ALIS) platform. Structure-based ligand design and optimization led to significant improvements in potency to the single digit nanomolar range and hundred-fold selectivity against CDK2.

Qiao, Lixin published the artcileStructure-activity relationship study of EphB3 receptor tyrosine kinase inhibitors, Application of Pyrazolo[1,5-a]pyridin-3-amine, the publication is Bioorganic & Medicinal Chemistry Letters (2009), 19(21), 6122-6126, database is CAplus and MEDLINE.

A structure-activity relationship study for a 2-chloroanilide derivative of pyrazolo[1,5-a]pyridine revealed that increased EphB3 kinase inhibitory activity could be accomplished by retaining the 2-chloroanilide and introducing a Ph or small electron donating substituents to the 5-position of the pyrazolo[1,5-a]pyridine. In addition, replacement of the pyrazolo[1,5-a]pyridine with imidazo[1,2-a]pyridine was well tolerated and resulted in enhanced mouse liver microsome stability. The structure-activity relationship for EphB3 inhibition of both heterocyclic series was similar. Kinase inhibitory activity was also demonstrated for representative analogs in cell culture. An analog (32, LDN-211904) was also profiled for inhibitory activity against a panel of 288 kinases and found to be quite selective for tyrosine kinases. Overall, these studies provide useful mol. probes for examining the in vitro, cellular and potentially in vivo kinase-dependent function of EphB3 receptor.

Ochiana, Stefan O. published the artcileRepurposing Human PDE4 Inhibitors for Neglected Tropical Diseases. Evaluation of Analogs of the Human PDE4 Inhibitor GSK-256066 as Inhibitors of PDEB1 of Trypanosoma brucei, COA of Formula: C3H5BN2O2, the publication is Chemical Biology & Drug Design (2015), 85(5), 549-564, database is CAplus and MEDLINE.

Cyclic nucleotide phosphodiesterases (PDEs) have been identified as important enzyme targets for drug development in both humans and Trypanosoma brucei, the causative agent of human African trypanosomiasis. With this in mind, the authors recently reported the profiling of a range of human phosphodiesterase inhibitors, showing that human PDE4 inhibitors tend to display the best potency against the trypanosomal phosphodiesterase TbrPDEB1. Among these was GSK-256066, a potent inhibitor of human PDE4 and a weak inhibitor of TbrPDEB1. In this report, the authors describe the results of a structure-activity relationship study of this chemotype, leading to the discovery of analogs with improved potency against TbrPDEB1 and micromolar inhibition of T. brucei cellular growth. The authors rationalize the potency trends via mol. docking of the new inhibitors into a recently reported apo structure of TbrPDEB1. The studies in this article will inform future efforts in repurposing human PDE inhibitors as antitrypanosomal agents.

Reid, Paul R. published the artcileDiscovery and optimization of a novel, selective and brain penetrant M₁ positive allosteric modulator (PAM): The development of ML169, an MLPCN probe, Recommanded Product: 1H-Pyrazole-4-boronic acid, the publication is Bioorganic & Medicinal Chemistry Letters (2011), 21(9), 2697-2701, database is CAplus and MEDLINE.

This Letter describes a chem. lead optimization campaign directed at VU0108370, a weak M₁ PAM hit with a novel chem. scaffold from a functional HTS screen within the MLPCN. An iterative parallel synthesis approach rapidly established SAR for this series and afforded VU0405652 (ML169) (I), a potent, selective and brain penetrant M₁ PAM with an in vitro profile comparable to the prototypical M₁ PAM, BQCA, but with an improved brain to plasma ratio.

Pastor, Richard M. published the artcileDiscovery and optimization of indazoles as potent and selective interleukin-2 inducible T cell kinase (ITK) inhibitors, Related Products of pyrazoles-derivatives, the publication is Bioorganic & Medicinal Chemistry Letters (2014), 24(11), 2448-2452, database is CAplus and MEDLINE.

There is evidence that small mol. inhibitors of the nonreceptor tyrosine kinase ITK, a component of the T-cell receptor signaling cascade, could represent a novel asthma therapeutic class. Moreover, given the expected chronic dosing regimen of any asthma treatment, highly selective as well as potent inhibitors would be strongly preferred in any potential therapeutic. Here the authors report hit-to-lead optimization of a series of indazoles, e.g. I [R = Et, HOCH₂, Me₂NCH₂CH₂, etc.] that demonstrate sub-nanomolar inhibitory potency against ITK with strong cellular activity and good kinase selectivity. The authors also elucidate the binding mode of these inhibitors by solving the x-ray crystal structures of the complexes.

Evaluation of 4-phenylphenalenones and structural analogs against the fungal pathogen Mycosphaerella fijiensis (causal agent of black sigatoka disease in bananas) under light-controlled conditions uncovered some key structural features for the design of photodynamic compounds Structure-activity relationship anal. revealed the importance of a chromophoric aryl-ketone and a steroidomimetic structural motif in the activity of the assayed compounds The results pointed to 1,2-dihydro-3H-naphtho[2′,1′:3,4]cyclohepta[1,2-b]furan-3-one, which displayed an activity in the range of propiconazole but with photodynamic behavior. The present work demonstrates that 1,2-dihydro-3H-naphtho[2′,1′:3,4]cyclohepta[1,2-b]heterocyclic-3-one derivatives can be used as potential lead compounds for the development of fungicides, relying on a dual mode of action.
