Melanesia Experiences in Marine Drug Discovery at University of the South Pacific” Prof. B. Aalbersberg and K.-D. Feussner CDDC, IAS, USP
2
Bioprospecting - Background 25-50% of western medicines are derived from natural sources (e.g. aspirin, quinine, many anti- cancer agents and anti biotic drugs) Sales near $800 billion Process takes 15–20 years and costs $800 million 1 in 10,000 chance to develop medicine from given organism
3
Bioprospecting Process - 1 1.Permitting 2.Collecting 3.Extraction 4.Bioactivity Testing 5.Fractionation and Purification 6.Structure elucidation
4
Bioprospecting Process - 2 7.Organism Identification and Recollection 8.Structure – Activity Relationships 9.Toxicology Tests 10.Clinical Trials 11.Pray
5
Microbial Bioprospecting 1.Plating substrate 2.Colony Isolation and Purification 3.Fermentation 4.Extraction of Ferment 5.As in macroorganisms
6
Genetic Material DNA can be extracted, amplified and sequenced Sections of genome that are responsible for various functions (diseases, chemical production) can be identified
7
Work at USP 1.Permitting 2.Collecting 3.Extraction 4.Bioactivity Testing 5.Fractionation and Purification 6.Structure elucidation
8
Types of Samples Organism Extracted chemicals Extracted DNA
9
Convention on Biological Diversity and Access and Benefit Sharing Prior informed consent Fair agreement on mutually agreed terms Participation and sharing of benefits Environmentally sound uses
10
Types of Benefits Cash (sample fee and royalties) Help in resource management Voucher specimen Legal review Participation in work and capacity building Sharing results Transfer of technology Access to biotech outcomes
