One of the key areas we specialise in the Computational Chemistry Group in Chemistry and UCL, is the development of models from nano- to macro-scales, especially the modelling and understanding complex biological systems, from receptor-ligand binding right up to whole human systems. At the smaller end of that scale, we have been collaborating with Professor Whiting at Durham University, and now the Nevrargenics team, to develop more accurate retinoid-ligand binding models and the accurate calculation of the energies of binding. This type of approach could not only be game changing for the genuine ab initio design of the next generation of retinoid drugs, support our understanding of their mode of action, and help drive the invention of truly disease modifying drugs for what are currently, a wide range of neurodegenerative diseases.
