Cell Signalling, Drug Discovery & Medicinal Chemistry: Work concerns the design, synthesis and biological evaluation of active organic molecules at the interfaces of Chemistry & Biology, ultimately aimed at the dissection of biological mechanisms through chemical biological intervention or, at the interface of Chemistry & Medicine, through intelligent drug design & discovery with the aim of moving translationally from 'concept to clinic'. A unifying general theme is centered around cellular signalling processes and concerns both entities involved in the chemistry of signal transduction processes, particularly those involving cyclitol and nucleotide-based second messengers signalling through the elevation of intracellular Ca 2+, and endocrine signalling and its modulation in oncology and endocrinology. Synthetic cyclitol, carbohydrate, nucleotide and medicinal chemistry is underpinned by biochemical assays, protein crystallography and by in silico methods for structure-based design. The two main themes are:
The Chemistry of Signal Transduction:
Inositol phosphate-mediated cellular signalling and the roles of the higher inositol polyphosphates; Cyclic ADP-ribose - a nucleotide second messenger; ADP-ribose, a nucleotide second messenger & TRPM2; NAADP - a nucleotide second messenger.
Anticancer Drug Design, Discovery & Translational Medicine.
Drug design for hormone-dependent and independent diseases; inhibitor design for sulfatases; design of multi-targeting drug candidates for oncology.
