- Discovery of Substituted 1H-Pyrazolo[3,4-b]pyridine Derivatives as Potent and Selective FGFR Kinase Inhibitors
-
Fibroblast growth factor receptors (FGFRs) are important targets for cancer therapy. Herein, we describe the design, synthesis, and biological evaluation of a novel series of 1H-pyrazolo[3,4-b]pyridine derivatives as potent and selective FGFR kinase inhibitors. On the basis of its excellent in vitro potency and favorable pharmacokinetic properties, compound 7n was selected for in vivo evaluation and showed significant antitumor activity in a FGFR1-driven H1581 xenograft model. These results indicated that 7n would be a promising candidate for further drug development.

- Preparation of (4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepin-5-ylidene)acetamide derivatives as novel arginine vasopressin V2 receptor agonists
-
The present work describes the discovery of novel series of (4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepine-5-ylidene)acetamide derivatives as arginine vasopressin (AVP) V2 receptor agonists. By replacing the amide juncture in YM-35278 with a direct ring connection gave compound 10a, which acts as a V2 receptor agonist. These studies provided the potent, orally active non-peptidic V2 receptor agonists 10a and 10j.

- Applicability aspects of transition metal-catalyzed aromatic amination protocols in medicinal chemistry
-
The application of palladium- and coppercatalyzed reactions for the aromatic amination of pharmacologically relevant scaffolds is investigated. The focus is set on the scope of several protocols for the introduction of amines of broad structural diversity, allowing for the synthesis of numerous derivatives of one biological hit structure for screening in biological assay systems. Thus, attaining optimized yields and TONs had not a major priority, most important were practical aspects, that is no further purification and drying of reagents and solvents had to be envisaged, ideally only a few transition metalbased protocols had to be applied for synthesizing structurally diverse compounds in sufficient amounts (several milligrams) for screening without any finetuning of conditions and catalytic systems.
