ESR2: Novel 3D fragments
Download the full description of this project: ESR2: Novel 3D fragments
The applicant will join a team working on the design, synthesis and assessment of novel 3D fragments. The focus of the project is on chemical synthesis with opportunities to explore aspects of cheminformatics (for analysing compounds), molecular modelling (how the compounds bind to proteins) and experimental fragment screening.
1. Design of 3-D fragment library.
2. Synthesis of selected fragments.
Most of the compounds in fragment libraries[1, 2] are commercially available small molecules which have been selected by medicinal chemists based on their experience on ease of synthesis and what they have seen before in existing drugs. This means that many fragments are flat heterocycles. This has worked well for many proteins that bind to and recognise metabolites such as ATP, but may not be ideal for other proteins, such as those that bind carbohydrates. There are also analyses which suggest that more 3D compounds have better properties as drugs. One of the major issues with such compounds is they contain multiple stereo-‐centres which makes synthesis to improve the compounds more challenging. Some of the synthetic chemistry developed at York provides a way to achieve this. This project builds on recent work in the O’Brien laboratory (aided by cheminformatics analysis by the Hubbard group) to design and synthesise novel 3D lead-‐like compounds. The compounds will be designed based on common features of drug molecules and some of our 3-‐D fragments are shown below. Principal moments of inertia (PMI) plots, which are a representation of 3-‐D space, will be used to evaluate the designed compounds and selection criteria will be developed to identify compounds. Selected compounds will then be synthesised.
The skills required are an interest and aptitude for compound synthesis; the amount of time spent outside of the synthetic laboratory (on modelling or experimental screening) will depend on the interests of the successful applicant.
