- Evaluation of aromatic 6-substituted thienopyrimidines as scaffolds against parasites that cause trypanosomiasis, leishmaniasis, and malaria

Target repurposing is a proven method for finding new lead compounds that target Trypanosoma brucei, the causative agent of human African trypanosomiasis. Due to the recent discovery of a lapatinib-derived analog 2 with excellent potency against T. brucei (EC50 = 42 nM) and selectivity over human host cells, we have explored other classes of human tyrosine kinase inhibitor scaffolds in order to expand the range of chemotypes for pursuit. Following library expansion, we found compound 11e to have an EC50 of 84 nM against T. brucei cells while maintaining selectivity over human hepatocytes. In addition, the library was tested against causative agents of Chagas' disease, leishmaniasis, and malaria. Two analogs with sub-micromolar potencies for T. cruzi (4j) and Plasmodium falciparum (11j) were discovered, along with an analog with considerable potency against Leishmania major amastigotes (4e). Besides identifying new and potent protozoan growth inhibitors, these data highlight the value of concurrent screening of a chemical library against different protozoan parasites. This journal is

- Cross-coupling reaction on N-(3,5-dibromo-2-pyridyl)piperazines: Regioselective synthesis of 3,5-disubstituted pyridylpiperazines
-
Unsymmetrical 3,5-disubstituted pyridylpiperazines were prepared from tribromopyridine in three coupling reactions. Key to the success of the syntheses is the palladium-catalyzed regioselective cross-coupling reaction in the 3-position of N-(3,5-dibromo-2

- Acridone-based inhibitors of inosine 5′-monophosphate dehydrogenase: Discovery and SAR leading to the identification of N-(2-(6-(4-ethylpiperazin-1- yl)pyridin-3-yl)propan-2-yl)-2-fluoro-9-oxo-9,10-dihydroacridine-3-carboxamide (BMS-566419)
-
Inosine monophosphate dehydrogenase (IMPDH), a key enzyme in the de novo synthesis of guanosine nucleotides, catalyzes the irreversible nicotinamide-adenine dinucleotide dependent oxidation of inosine-5′- monophosphate to xanthosine-5′-monophosphate. Mycophenolate Mofetil (MMF), a prodrug of mycophenolic acid, has clinical utility for the treatment of transplant rejection based on its inhibition of IMPDH. The overall clinical benefit of MMF is limited by what is generally believed to be compound-based, dose-limiting gastrointestinal (GI) toxicity that is related to its specific pharmacokinetic characteristics. Thus, development of an IMPDH inhibitor with a novel structure and a different pharmacokinetic profile may reduce the likelihood of GI toxicity and allow for increased efficacy. This article will detail the discovery and SAR leading to a novel and potent acridone-based IMPDH inhibitor 4m and its efficacy and GI tolerability when administered orally in a rat adjuvant arthritis model.
