Research in the Majireck group aims to (1) develop new methodologies for synthesis of biologically interesting small molecules and (2) openly collaborate with the biomedical research community to identify small molecule probes of human disease biology.
Toward our first aim, we have recently identified a rapid approach to biologically active dihydropyrimidines (DHPs). Similar compounds (mainly pyrimidines) are known to exhibit anti-cancer and/or anti-infective properties, often by acting as cytotoxic anti-metabolites within pathogenic cells. Our strategy enables access to the structurally-related, but synthetically challenging DHP scaffolds which we intend to evaluate for their activity in relevant biological assays.
A second project utilizes recently developed transition-metal catalysis to synthesize a collection of N-(2-alkoxyvinyl)sulfonamides. We hypothesize that derivatives of such compounds may serve as useful biological probes of metal-binding proteins such as histone deacetylases, an essential family of chromatin-modifying enzyme involved in epigenetic regulation.
In other work, our lab is developing a general approach for the synthesis of neuroactive alkaloids related to indolizidine. Using structure-activity relationships, we hope to identify critical factors that enable blood-brain-barrier penetrance within this class of compound. As probes, these alkaloids may be useful for studying the role(s) of key nodes (e.g. G-protein-coupled receptors or ion-channels) within the complex cell circuitry of the brain.
Compounds synthesized by our lab will be screened for biological activity, both at Hamilton College and at non-profit biomedical research institutes such as the Broad Institute of Harvard & MIT, MIT’s Koch Institute for Integrative Cancer Research, and the Department of Comparative Pathobiology at Purdue University.
Relevant publications: 10-12, 14, preprint, manuscript in prepn. (and 2-6 from graduate work.)
Functional groups that have been underexplored, typically due to the lack of viable synthetic procedures, provide fertile grounds for new reaction discovery and applications. The Majireck group is currently exploiting several recent methodologies from our laboratory that explore unusual functional groups for the development of new and useful reactions toward biologically important targets. For example, in earlier work we have leveraged the recent developments in Rh-catalyzed decomposition of N-sulfonyl-1,2,3-triazoles to generate neuroactive phthalan and/or phenethylamine structures with a versatile N-(1-alkoxyvinyl)sulfonamide moiety. This obscure but promising functional group has, until recently, been relatively unexplored. However, research by our group and others have transformed this subclass of compound into a valuable N,O-containing synthon for organic synthesis - a topic that our labratory will publish a review on soon.
More recently, our lab have discovered >35 examples of, until recently, rare N-quaternized ketene N,O-acetals. These unusual constructs are currently being investigated as “trapped ketenium ion” reagents for a variety of purposes including cycloadditions and acid-catalyst free electrophilic aromatic substitutions. Alternatively, these species may act as electrophiles in nucleophilic aromatic substitutions toward production of novel heterocycles.
