that must exist to trigger any obligation under national law or an international regime. At one end of the spectrum of possible uses of genetic resources is the use that the CBD was intended to capture. Such a situation arises when a genetic resource - for example, a leaf - is obtained from a CBD member, a compound is isolated from that leaf and the compound - without modification - becomes the active ingredient in a drug.
At the opposite end is the situation in which a company uses purely synthetic mechanisms to develop novel small molecule compounds, but tests the utility of those compounds with commonly available or staple genetic resources, such as cell lines.

Risk calculation is a fundamental factor influencing decisions regarding the investment of resources and companies who invest in research must have maximum certainty in order to ensure the legal security of any investment. Likewise, legal risk should be minimal and legal certainty must There are many common misunderstandings regarding the actual value of genetic resources for R&D. There is no straightforward means by which the association can be made. The industry argues that that the diversity of possible contributions, coupled with the overarching objective to promote responsible research, renders a detailed taxonomy of "nexus" both impractical and unnecessary. Higher expenditure and greater risk associated with drug development compared to drug discovery, coupled with the low probability that any one GR sample will lead to a commercial product9, are two such issues that are poorly understood. In addition, the internal competition between genetic resources research programs and other research programs within companies is often poorly appreciated10.

Benefits for AstraZeneca and Medical Science
The Research and Development of a new medicine is a long process involving hundreds, if not thousands, of skilled scientists (chemists, biologists, pharmacists, doctors, etc). It can take 15 years from idea to market with the first few years spent investigating the idea and the last 8-12 years spent developing a specific molecule through the scientific, safety and clinical challenges. The challenges are great as over 90% of developments fail, even though compounds are carefully selected before they enter development.
The Pharmaceutical industry is always investigating new ideas and new leads for drug discovery, as there is considerable unmet medical need in society. The work of the Natural Product Discovery laboratory PHARMAMAR - ADVANCING CANCER CARE WITH MARINE RESOURCES Case study number two focuses on PharmaMar, a biopharmaceutical company whose mission is to advance cancer care through the discovery and development of innovative marine-derived medicines. The sea provides the starting point for research at PharmaMar.
More than 99% of marine biodiversity is as yet still un-explored and over millions of years marine life forms have evolved towards great biological and chemical diversity and the new chemical entities isolated from the marine organisms typically have entirely novel structures and often show great structural complexity.
These novel chemical structures often result in new modes of action against tumour cells that opens up the potential of new ways to treat cancer and it is hoped that this rich bio-diversity and chemical diversity provides qualitative advantages when discovering new drugs.
Over the last 20 years, PharmaMar has built up a unique collection of over 42,000 marine invertebrates and micro- organisms and approximately 7000 new chemical entities have been discovered and 30 new families of compounds identified. In additional, the company has a full pipeline of emerging products, including five compounds in clinical development and a portfolio of different molecules at different stages of pre-clinical development.
Only after 20 years of research and significant investment, has PharmaMar reached a position where it is able to plan commercial launch of its first marine-derived medicine. This attests to the length and complexity of the drug development process and the high up-front and sustained investment required to bring nature-inspired medicines The following text attempts to highlight the role natural resources can play in yielding bioactive molecules and the complexity and uncertainties involved in converting these molecules into medicines.
1. Challenges & risks with Natural Product research
The use of biodiversity for drug discovery is just one of many different possible options. These include knowledge-based approaches (using literature and patent-derived molecular entities, endogenous ligands or biostructural information) and purely serendipity- based methods (such as screening), as well as the These combined hurdles represent an additional barrier to developing new medicines using biodiversity. The positive side is that despite the higher risk there may be greater opportunity to be 2. Complexity of R&D
PharmaMar's business model has many similarities with those of most pharmaceutical companies. In particular, the outline of the research process presented earlier is very much the same.
companies in that all the new molecules developed by the company are derived from marine invertebrates or micro- organisms is an essential part of the drug discovery However, the creation of a natural product library is only the starting point. Without significant further work, it is impossible to know whether any individual natural product sample has any value for drug discovery.
To understand the role of biodiversity in the drug discovery process, it is important to understand the differences between a bioactive molecule, a drug-like molecule and a medicine.
2.1 Bioactive Molecules
The drug discovery process starts with the search for bio-active molecules.
Each natural sample is extracted and purified by chromatographic techniques in order to isolate a pure sample of the different molecules present. A few grams of natural sample is all that is required to provide sufficient quantity of the different molecules present to allow elucidation of their chemical structures and an initial assessment of the in vitro activity.
Even though most natural product samples contain a tremendous array of different molecules, the majority of the molecules present in such samples do not show in vitro activity. It has been estimated by the US National Cancer Institute (NCI) that just 1 % of samples from marine organisms tested in the laboratory reveal anti-tumour potential (which compares favourably with just 0.01% of samples of terrestrial origin).
The isolation and characterisation of a new molecule with in vitro activity, a bioactive molecule, from the natural source is an important early milestone in the drug development process.
Once a new bio-active molecule has been identified, PharmaMar follows all the usual steps required for any new medicine including a full programme of pre-clinical testing (to design a drug-like molecule) and clinical development (to produce a medicine).
2.2 Drug-like Molecules
Even though a compound from the natural source may possess in vitro activity, it is highly unlikely that it will also possess all the other characteristics (physiochemical and biological) required to become a successful medicine.
All bio-active molecules require significant further effort in order to optimise their properties and produce a drug- like molecule for the start of clinical trials. This process of optimization is critical for the downstream success.
Structural modifications may be introduced (using chemical, enzymatic or biological methods) to enhance certain aspects of the molecules properties. The new molecules thus obtained have chemical the original naturally but are not themselves using such compounds are best described as inspired by nature rather than natural medicines.
For administration to patients, all molecules need to be formulated. The resulting presentation (freeze-dried vial, capsule, tablet, cream etc) contains not only the active molecule (whether as found in nature or after modification) but also different excipients and other components to ensure the suitability of the formulation. Many sophisticated drug delivery technologies are also available to further optimise drug performance.
The conversion of a bioactive molecule into a medicine is a long and risky process. For example, following structural elucidation and identification of taxol as a new bioactive molecule, it took over 20 years to achieve FDA approval to market a medicine containing this molecule.
Furthermore, the chance of a bioactive molecule successfully negotiating all the hurdles and reaching the market are typically about 1 in 100.
2.4 Responsible Use of Natural Resources
The approach used permits the isolation of novel molecules from small samples of marine material. Once the anti- tumour activity of these chemical entities has been recognized and characterized, a synthetic process is established to produce further quantities for development and for commercial supply and to avoid dependence on the natural source and damage to the marine environment.
Invariably, the natural source would not be considered as an appropriate or viable source of larger quantities of the bioactive molecules, which are usually present in only minute amounts in the marine organisms.
3. Monetary and non-monetary benefits used
3.1 Partnership, collaboration and mutual benefits
Drug discovery at PharmaMar starts with the selective collection of small quantities of marine invertebrates and micro-organisms around the world. This work is carried out by experienced in-house marine biologists and in collaboration with worldwide local research institutions.
PharmaMar supports the protection, conservation and sustainable use of the precious resources from the sea and the fair and equitable sharing of the benefits.
Ensuring the survival of existing biodiversity is essential for future business survival.
The PharmaMar approach to drug discovery not only contributes to the development of possible new treatments from just a few grams of marine sample, but also furthers knowledge and conservation of marine ecosystems. Such information is shared with local communities and teaching institutions and benefits both the local institutions and PharmaMar who uses the knowledge gained to optimise future exploration activities.
PharmaMar is supported by an extensive worldwide network of collaborators of all types who provide expertise and support throughout the drug discovery and development process from bio-prospecting and drug discovery through to clinical development, regulatory and marketing activities.
The opportunity to work with an international network of first class collaborators is essential in ensuring the success of the overall drug discovery process and is an important part of ensuring that the company remains at the forefront of all the best-practice within the Each of the external collaborations is designed to complement in-house collaborations are only possible through the fair of any benefits that may NOVARTIS - COLLABORATION AND COLLECTIVE GAIN The importance or impact of technologies and research concepts are permanently balanced in industry. The same is true for the natural products programs in the pharmaceutical industry. There are many good reasons to leverage the unusual diversity of evolutionarily selected molecules in drug discovery efforts. On the other hand, the use of these molecules means facing intrinsic hurdles or challenges, which some companies may not be willing to take on. Novartis is strongly com- mitted to natural products based research. A key as- pect of this commitment is the creation of external partnerships with coun- tries of high biological diversity. Currently No- vartis focuses on collabo- rations with China and Thailand and in parallel is constantly evaluating other opportunities in or- der to diversify the access to biological sources.
Partner institutes chosen by Novartis are interna- specialists in the field of microbial and plant re- lated natural products research. An integral part of current partner- ship agreements is the exchange of know-how by on-site training sessions, the education of scien- tists in the laboratories of the Novartis Institutes of Biomedical Research and the financing of technol- ogy related investments. In the cooperation con- tracts, success related milestones or royalty pay- ments are also defined.
The project and investment goals are mutually defined in joint steering com- mittee meetings, which are an important instru- ment to monitor project progress and, if neces- sary, to redirect collabo- rations. In the microbial sourcing collaborations, Novartis is responsible for the implementation of specific microbiology skills at the site of partner institutes, guaranteeing the high quality criteria of microbial strains as start- ing points for Novartis' in- ternal project activities.
A particularly success- ful cooperation with the Shanghai Institute of Ma- teria Medica should be mentioned here. Over a period of 6 years, Novartis received more than 1500 isolated molecules from plants used in Chinese traditional medicine from its Chinese partner. From its side, Novartis contrib- uted significantly to the implementation of tech- nological innovations at the Shanghai based insti- tute. There are currently several compounds be- ing considered for closer preclinical investigation at Novartis.
Although the Rio-Conven- tion came into force more than 10 years ago, legal uncertainties regarding entitlement of institutes to start bioprospecting endeavours with indus- trial partners remain; sibilities and authorities of national government and local administration, lack of official contact points within a country and the much discussed Access and Benefit Shar- ing framework. However, this issue is by no means an exclusive problem of biodiversity rich coun- tries: the majority of the Western nations have also failed to implement suitable modus operandi.
The most advanced No- vartis project benefiting from traditional knowl- edge is related to a tra- ditional Chinese medi- cine. Artemisia annua is a plant, which has been used in China to fight ma- laria for over 2000 years.
The active ingredient, ar- temisinin, was isolated in China in 1977 and demon- strated potent and highly selective activity against Plasmodia. The multi drug resistant Plasmodium fal- ciparum can be effectively killed with the unusually structured natural prod- uct. In a joint development project with Chinese gov- ernmental institutes, an artemisinin derivative to- gether with another plas- modicidal drug substance were combined in one tab- let and were introduced successfully as Coartem(r)/ Riamet(r) onto the pharma- ceutical market in 1999. In 2001, the WHO added the anti-malaria drug to its es- sential medicines list.
In the following years, No- vartis implemented full supply chain management. were made in seed develop- ment; horticulture capacity was expanded in Africa and China and manufacturing infrastructure was put in place.

myths in order to establish valid objectives. In section 2, examples of differences of opinion about fundamental concepts that underpin discussion of ABS were given. Underlying these differences is a lack of global consensus on almost every aspect of what might be termed the appropriate "regulatory philosophy." The preferred regulatory instruments depend in turn on one's perception of the problem. Those who believe, like some NGO's, that a generalised theft of genetic resources is taking place and who place the lack of ownership above the recognition of innovation will approach the question of regulation from a different point to those who believe that the core issue is to promote responsible use. An approach that is purely seeking to prohibit need deal only with the identification of certain actions, whereas as one that seeks to be facilitative must proceed from a deeper understanding of the processes involved.
The decisions made regarding ABS policies and laws, their clarity and workability will clearly affect the readiness of industry to invest in certain types of resource research and development. As legal certainty decreases and risks increase, the likelihood of investment in development of genetic resources will in parallel decrease. Any ABS framework must facilitate both access and benefit sharing and aim to ensure legal certainty. Without research investment, there will be neither commercial rewards to share with countries of origin nor technology to transfer to 5.2 AVOIDING THE WRONG PATH The example of "biopiracy" shows what happens when responsible use of NP and fair benefit sharing.
