Synthesis, crystal structure and biological activity of novel diester cyclophanes

A series of novel diester cyclophanes was synthesized by esterification of 1,2-benzenedicarbonyl chloride with eight different diols under high dilution conditions. The structures of the compounds were verified by elemental analysis, 1H nuclear magnetic resonance (NMR), IR spectroscopy and high resolution mass spectrometry (HRMS). The crystal structures of two compounds were characterized by single crystal X-ray diffractometry (XRD). All the new cyclophanes were evaluated for biological activities and the results showed that some of these compounds have low antibacterial or antifungal activities.

Iridium(I)-Catalyzed alpha-C(sp3)-H Alkylation of Saturated Azacycles

Saturated azacycles are commonly encountered in bioactive compounds and approved therapeutic agents. The development of methods for functionalization of the alpha-methylene C-H bonds of these highly privileged building blocks is of great importance, especially in drug discovery. While much effort has been dedicated toward this goal by using a directed C-H activation approach, the development of directing groups that are both general as well as practical remains a significant challenge. Herein, the design and development of novel amidoxime directing groups is described for Ir(I)-catalyzed alpha-C(sp3)-H alkylation of saturated azacycles using readily available olefins as coupling partners. This protocol extends the scope of saturated azacycles to piperidines, azepane, and tetrahydroisoquinoline that are incompatible with our previously reported directing group. A variety of olefin coupling partners, including previously unreactive disubstituted terminal olefins and internal olefins, are compatible with this transformation. The selectivity for a branched alpha-C(sp3)-alkylation product is also observed for the first time when acrylate is used as the reaction partner. The development of practical, one-step installation and removal protocols further adds to the utility of amidoxime directing groups.

Synthesis and biological evaluation of D-amino acid oxidase inhibitors

D-Amino acid oxidase (DAAO) catalyzes the oxidation of D-amino acids including D-serine, a full agonist at the glycine site of the NMDA receptor. A series of benzo[d]isoxazol-3-ol derivatives were synthesized and evaluated as DAAO inhibitors. Among them, 5-chlorobenzo[d]isoxazol-3-ol (CBIO) potently inhibited DAAO with an IC50 in the submicromolar range. Oral administration of CBIO in conjunction with D-serine enhanced the plasma and brain levels of D-serine in rats compared to the oral administration of D-serine alone.

Design and synthesis of tricyclic corticotropin-releasing factor-1 antagonists

Antagonists of the corticotropin-releasing factor (CRF) neuropeptide should prove to be effective in treating stress and anxiety-related disorders. In an effort to identify antagonists with improved physicochemical properties, new tricyclic CRF1 antagonists were designed, synthesized, and tested for biological activity. As a result of studies aimed at establishing a relationship between structure and CRF1 binding affinity, NBI 35965 (12a) was identified as a high-affinity antagonist with a pKi value of 8.5. Compound 12a proved to be a functional CRF1 antagonist with pIC50 values of 7.1 and 6.9 in the in vitro CRF-stimulated cAMP accumulation and ACTH production assays, respectively, and 12a also reduced CRF or stress induced ACTH production in vivo.

Fragment-Based Drug Discovery of Inhibitors of Phosphopantetheine Adenylyltransferase from Gram-Negative Bacteria

The discovery and development of new antibiotics capable of curing infections due to multidrug-resistant and pandrug-resistant Gram-negative bacteria are a major challenge with fundamental importance to our global healthcare system. Part of our broad program at Novartis to address this urgent, unmet need includes the search for new agents that inhibit novel bacterial targets. Here we report the discovery and hit-to-lead optimization of new inhibitors of phosphopantetheine adenylyltransferase (PPAT) from Gram-negative bacteria. Utilizing a fragment-based screening approach, we discovered a number of unique scaffolds capable of interacting with the pantetheine site of E. coli PPAT and inhibiting enzymatic activity, including triazolopyrimidinone 6. Structure-based optimization resulted in the identification of two lead compounds as selective, small molecule inhibitors of bacterial PPAT: triazolopyrimidinone 53 and azabenzimidazole 54 efficiently inhibited E. coli and P. aeruginosa PPAT and displayed modest cellular potency against the efflux-deficient E. coli DeltatolC mutant strain.
