Preparation of 2-hydroxybenzamidines from 3-aminobenzisoxazoles

2-Hydroxybenzamidines have been prepared from 3-aminobenzisoxazoles by reductive cleavage of the nitrogen-oxygen bond using catalytic hydrogenation, Zn/AcOH or NiCl2/NaBH4. This ring-opening reaction can be accomplished chemoselectively in the presence of a variety of hydrogenation-sensitive functional groups including an aryl bromide, benzyl carbamate, and olefin.

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.

A compilation of two decades of mutagenicity test results with the ames Salmonella typhimurium and L5178Y mouse lymphoma cell mutation assays

As previously reported [Cameron, T. P., Rogers-Back, A. M., Lawlor, T. E., Harbell, J. W., Seifried, H. E., and Dunkel, V. C. (1991) Gentoxicity of multifunctional acrylates in the Salmonella/mammalian-microsome assay and mouse lymphoma TK+/- assay. Environ. Mol. Mutagen. 17, 264-271], the National Cancer Institute (NCI) shares the responsibility of selecting the most significant chemicals for carcinogenicity testing by the National Toxicology Program (NTP) and has used data from Salmonella and mouse lymphoma mutagenicity assays to aid in the selection and prioritization of chemicals to be further evaluated in chronic 2 year rodent studies. In addition, a number of antineoplastic and anti-AIDS drugs in preclinical evaluation were tested for the NCI’s Division of Cancer Treatment Toxicology Branch. In the NCI/NTP chemical selection process, it is no longer necessary to test chemicals prior to sending them to the NTP so the NCI program has ceased performing mutagenicity tests. Some of the testing data has been made available in summary form in the Chemical Carcinogenisis Research Information System (CCRIS), which is searchable on the NLM TOXNET system. The limitations in using this source are that only summary results are available and many negative test results are not included. A summary table that presents the results for each compound is provided in the Appendix with raw data provided in the Supporting Information. The Appendix table contains the compound name, CAS number, and a summary of the data from the Ames test and the mouse lymphoma assay.

Novel benzisoxazole derivatives as potent and selective inhibitors of acetylcholinesterase

A series of N-benzylpiperidine benzisoxazoles has been developed as potent and selective inhibitors of the enzyme acetylcholinesterase (AChE). The benzisoxazole heterocycle was found to be an appropriate bioisosteric replacement for the benzoyl functionality present in the N-benzylpiperidine class of inhibitors. The title compounds were synthesized by alkylating 3- methyl-1,2-benzisoxazoles with an iodo piperidine derivative as the key step. Benzisoxazoles 1b-j,o displayed potent inhibition of AChE in vitro with IC50’s = 0.8-14 nM. Particularly interesting were N-acetyl and morpholino derivatives 1g (IC50 = 3 nM) and 1j (IC50 = 0.8 nM), respectively, which displayed outstanding selectivity for acetyl- over butyrylcholinesterase, in excess of 3 orders of magnitude. N-acetyl 1g also displayed a favorable profile in vivo. This analog showed a dose-dependent elevation of total acetylcholine in mouse forebrain after oral administration with an ED50 = 2.4 mg/kg. In addition, 1g was able to reverse amnesia in a mouse passive avoidance model at doses of 3.2 and 5.6 mg/kg with an average reversal of 89.7%. Molecular dynamics simulations were used to study the possible binding modes of N-benzylpiperidine benzisoxazoles to AChE from Torpedo californica. Key structural insights were obtained regarding the potency of this class of inhibitors. Specifically, Asp-72, Trp-84, Trp-279, Phe-288, and Phe-330 are implicated in the binding of these inhibitors. The N-benzylpiperidine benzisoxazoles may be suitable compounds for the palliative treatment of Alzheimer’s Disease.
