In this review, we consider green chemistry metrics, related software tools, and the opportunities and challenges for their use in research laboratories. We provide an overview of state-of-the-art software designed both to aid researchers in planning... Read More about Software tools for green and sustainable chemistry.

Structural and biochemical evaluation of bisubstrate inhibitors of protein arginine N-methyltransferases PRMT1 and CARM1 (PRMT4) (2020)
Journal Article
Gunnell, E. A., Al-Noori, A., Muhsen, U., Davies, C. C., Dowden, J., & Dreveny, I. (2020). Structural and biochemical evaluation of bisubstrate inhibitors of protein arginine N-methyltransferases PRMT1 and CARM1 (PRMT4). Biochemical Journal, 477(4), 787–800. https://doi.org/10.1042/bcj20190826

Attenuating the function of protein arginine methyltransferases (PRMTs) is an objective for the investigation and treatment of several diseases including cardiovascular disease and cancer. Bisubstrate inhibitors that simultaneously target binding sit...

Iron-catalyzed indolizine synthesis from pyridines, diazo compounds, and alkynes (2017)
Journal Article
Douglas, T., Pordea, A., & Dowden, J. (in press). Iron-catalyzed indolizine synthesis from pyridines, diazo compounds, and alkynes. Organic Letters, 19(23), https://doi.org/10.1021/acs.orglett.7b03252

The iron (III) catalyzed synthesis of indolizines from commercially available alkyne, pyridine, and diazo precursors is reported. This mild, expedient method is tolerant of various solvents and proceeds with as little as 0.25 mol % [Fe(TPP)Cl]. Signi...

Calculating singlet excited states: comparison with fast time-resolved infrared spectroscopy of coumarins (2015)
Journal Article
Hanson-Heine, M. W., Wrigglesworth, A., Uroos, M., Calladine, J. A., Murphy, T. S., Hamilton, M., Clark, I. P., Towrie, M., Dowden, J., Besley, N. A., & George, M. W. (2015). Calculating singlet excited states: comparison with fast time-resolved infrared spectroscopy of coumarins. Journal of Chemical Physics, 142(15), 1-7. https://doi.org/10.1063/1.4917311

In contrast to the ground state, the calculation of the infrared (IR) spectroscopy of molecular singlet excited states represents a substantial challenge. Here we use the structural IR fingerprint of the singlet excited states of a range of coumarin...

Alkaloid inspired spirocyclic oxindoles from 1,3-dipolar cycloaddition of pyridinium ylides (2013)
Journal Article
Day, J., Uroos, M., Castledine, R. A., Lewis, W., McKeever-Abbas, B., & Dowden, J. (2013). Alkaloid inspired spirocyclic oxindoles from 1,3-dipolar cycloaddition of pyridinium ylides. Organic and Biomolecular Chemistry, 11(38), 6502-6509. https://doi.org/10.1039/c3ob41415a

Cycloaddition reactions between pyridinium ylides and 3-alkenyl oxindoles that proceed in high yield and with very good regio- and diastereoselectivity are reported. The resulting cycloadducts have the same stereochemistry of biologically active oxin... Read More about Alkaloid inspired spirocyclic oxindoles from 1,3-dipolar cycloaddition of pyridinium ylides.
