Inorganic and organometallic compounds are also useful as drugs e. In particular, medicinal chemistry in its most common practice—focusing on small organic molecules—encompasses synthetic organic chemistry and aspects of natural products and computational chemistry in close combination with chemical biology , enzymology and structural biology , together aiming at the discovery and development of new therapeutic agents. Practically speaking, it involves chemical aspects of identification, and then systematic, thorough synthetic alteration of new chemical entities to make them suitable for therapeutic use.
It includes synthetic and computational aspects of the study of existing drugs and agents in development in relation to their bioactivities biological activities and properties , i.
Pharmaceutical chemistry is focused on quality aspects of medicines and aims to assure fitness for purpose of medicinal products. At the biological interface, medicinal chemistry combines to form a set of highly interdisciplinary sciences, setting its organic, physical , and computational emphases alongside biological areas such as biochemistry , molecular biology , pharmacognosy and pharmacology , toxicology and veterinary and human medicine ; these, with project management , statistics , and pharmaceutical business practices, systematically oversee altering identified chemical agents such that after pharmaceutical formulation , they are safe and efficacious, and therefore suitable for use in treatment of disease.
Discovery is the identification of novel active chemical compounds, often called "hits", which are typically found by assay of compounds for a desired biological activity. In addition, hits also routinely originate from structural observations of small molecule "fragments" bound to therapeutic targets enzymes, receptors, etc. Finally, hits also regularly originate from en-masse testing of chemical compounds against biological targets, where the compounds may be from novel synthetic chemical libraries known to have particular properties kinase inhibitory activity, diversity or drug-likeness, etc.
While a number of approaches toward the identification and development of hits exist, the most successful techniques are based on chemical and biological intuition developed in team environments through years of rigorous practice aimed solely at discovering new therapeutic agents. Further chemistry and analysis is necessary, first to identify the "triage" compounds that do not provide series displaying suitable SAR and chemical characteristics associated with long-term potential for development, then to improve remaining hit series with regard to the desired primary activity, as well as secondary activities and physiochemical properties such that the agent will be useful when administered in real patients.

The final synthetic chemistry stages involve the production of a lead compound in suitable quantity and quality to allow large scale animal testing, and then human clinical trials. This involves the optimization of the synthetic route for bulk industrial production, and discovery of the most suitable drug formulation.
The former of these is still the bailiwick of medicinal chemistry, the latter brings in the specialization of formulation science with its components of physical and polymer chemistry and materials science. The synthetic chemistry specialization in medicinal chemistry aimed at adaptation and optimization of the synthetic route for industrial scale syntheses of hundreds of kilograms or more is termed process synthesis , and involves thorough knowledge of acceptable synthetic practice in the context of large scale reactions reaction thermodynamics, economics, safety, etc.
Critical at this stage is the transition to more stringent GMP requirements for material sourcing, handling, and chemistry. The synthetic methodology employed in medicinal chemistry is subject to constraints that do not apply to traditional organic synthesis. Owing to the prospect of scaling the preparation, safety is of paramount importance. The potential toxicity of reagents affects methodology. The structures of pharmaceuticals are assessed in many ways, in part as a means to predict efficacy, stability, and accessibility.
Lipinski's rule of five focus on the number of hydrogen bond donors and acceptors, number of rotatable bonds, surface area, and lipophilicity.
Students will undertake a laboratory-based research project lasting 10months. An interim report is submitted after five months, and at the end of the project each student writes a dissertation, gives a short presentation and has a viva voce examination. The programme is delivered through a combination of lectures, problem classes, workshops and projects.
Assessment is through unseen written examination, coursework, project reports and presentations. Students can be self-funded or find sponsorship from funding agencies such as research councils, the European Union, industry or charities. There are also a number of Graduate School Scholarships and departmental bursaries and prizes available. For a comprehensive list of the funding opportunities available at UCL, including funding relevant to your nationality, please visit the Scholarships and Funding website.
The MRes has been developed in response to the needs of the pharmaceutical and biotechnology sectors for highly qualified students as leaders in the discovery of new medicines. The pharmaceutical sector is a major employer in the UK and high-quality graduates with an understanding of the sector are always in demand. Our recent graduates have taken up PhD positions, are working in industry and have entered teacher training. This degree involves a cutting-edge research project in the laboratory a member of research staff at UCL Chemistry.
This is one of the leading research departments in the UK with staff undertaking world-leading research in all areas of chemistry and chemical biology. Department: Chemistry. Students are advised to apply as early as possible due to competition for places.
Those applying for scholarship funding particularly overseas applicants should take note of application deadlines. This MRes is aimed at students who wish to gain a detailed understanding of the context of organic chemistry research. It is also suitable for professionals working in industry who wish to develop their research skills.
