A UX Journey into the World of Early Drug DiscoveryJennifer Cham
Developing new medicines is an extremely challenging process with more than 50% of new medicines failing in late-stage development where the cost is the greatest. One of the main reasons for attrition is insufficient knowledge about the nature of the gene or protein (target) involved in a disease. Scientists in pharmaceutical research and development use diverse data and software applications to aid decision-making for drug target identification and validation.
We have been designing a new web portal to support researchers working within the pharmaceutical industry and academic organisations with the aim to make early drug target identification more efficient.
We will report on how we applied a range of participatory design methods including interviews, observations, sketching workshops, paper prototyping and usability testing to understand how experts carry out the very early stages of drug discovery. We will discuss the challenges of working in this domain and the extent to which standard UX approaches helped us understand what matters for our potential users so we could design and deliver solutions within an Agile framework. We also mention when popular UX methods didn't work in this complex environment and how we addressed these issues.
This work has been carried out via the Centre for Therapeutic Target Validation, a partnership between the European Bioinformatics Institute, the Wellcome Trust Sanger Institute and GlaxoSmithKline. See www.targetvalidation.org

Stable Drug Designing by Minimizing Drug Protein Interaction Energy Using PSO csandit
Each and every biological function in living organism happens as a result of protein-protein interactions. The diseases are no exception to this. Identifying one or more proteins for a
particular disease and then designing a suitable chemical compound (known as drug) to destroy these proteins has been an interesting topic of research in bio-informatics. In previous methods,drugs were designed using only seven chemical components and were represented as a fixedlength
tree. But in reality, a drug contains many chemical groups collectively known as
pharmacophore. Moreover, the chemical length of the drug cannot be determined before
designing the drug.
In the present work, a Particle Swarm Optimization (PSO) based methodology has been
proposed to find out a suitable drug for a particular disease so that the drug-protein interaction
becomes stable. In the proposed algorithm, the drug is represented as a variable length tree and essential functional groups are arranged in different positions of that drug. Finally, the structure of the drug is obtained and its docking energy is minimized simultaneously. Also, the
orientation of chemical groups in the drug is tested so that it can bind to a particular active site of a target protein and the drug fits well inside the active site of target protein. Here, several inter-molecular forces have been considered for accuracy of the docking energy. Results showthat PSO performs better than the earlier methods.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

An overview of drug discovery
1. An Overview of Drug Discovery
Peter W Kenny (pwk.pub.2008@gmail.com)
2. Some things that are hurting Pharma
• Having to exploit targets that are weakly-linked to
human disease
• Inability to predict idiosyncratic toxicity
• Inability to measure free (unbound) physiological
concentrations of drug for remote targets (e.g.
intracellular or within blood brain barrier)

The prototypical benzoic acid can be accommodated at both sites and, provided that binding can be
observed, will deliver a hit against both targets See Blomberg et al JCAMD 2009, 23, 513-525 |
http://dx.doi.org/10.1007/s10822-009-9264-5 | This way of thinking about molecular complexity is
similar to the ‘needle’ concept introduced by Roche researchers. See Boehm et al J. Med. Chem.
