Fruit flies for anti-pain drug discovery.

Recent work has indicated that fruit flies (Drosophila melanogaster) can be used in nociception research. Genetic screening identified a gene, painless, that is required for thermal and mechanical nociception in Drosophila larvae. On the other hand, pharmacological techniques and noxious heat were used to assay antinocieceptive behavior in intact adult Drosophila. In general, animal models for pain research are bound by ethical concerns. Since no serious ethical controversies have been raised regarding experiments in insects, Drosophila may be, for the time being an ethically acceptable animal model for combined genetic and pharmacological analgesia research.

Plants as source of drugs.

This work presents a study of the importance of natural products, especially those derived from higher plants, in terms of drug development. It describes the main strategies for obtaining drugs from natural sources, fields of knowledge involved, difficulties and perspectives. It also includes a brief discussion of the specific situation in Brazil regarding the use of, trade in, and research into therapeutic resources of natural origin and the general lack of awareness of the use of potentially toxic plants, mainly in folk medicine.

Drug design and development. A realistic appraisal.

The discovery of new biologically-therapeutically active structures continues to depend on screening and on isolated observations of unexpected drug metabolites and drug activities. The selection of therapeutically improved and useful chemicals requires molecular modification. Refinements in intuitive and physiochemical methodology can provide shortcuts in random choices and permit extrapolations of some facets of activity with a variable degree of accuracy. The final decisions concerning the usefulness of a drug remain in the domain of experimental and clinical pharmacology.

The UIC ICBG (University of Illinois at Chicago International Cooperative Biodiversity Group) Memorandum of Agreement: a model of benefit-sharing arrangement in natural products drug discovery and development.

The Convention on Biodiversity mandates a new approach to the discovery of natural product drugs, one that incorporates concepts of national ownership of genetic resources, intellectual property rights in traditional knowledge, and sharing of economic benefits with countries that are the source of new natural products. The International Cooperative Biodiversity Group (ICBG) program was established to support experimentation in implementation of the Convention through development and execution of international agreements for bioprospecting. The agreement of one such ICBG program, between the University of Illinois at Chicago and institutions in Vietnam and Laos, is presented here. The core elements contained in the single, five-way Memorandum of Agreement are the arrangements for intellectual property rights, treatment of informed consent, and plans for benefit-sharing (including the sharing of short- and long-term royalty benefits, capacity building, and community reciprocity). Program participants were able to develop a practical and flexible agreement that satisfies the wishes of all institutions that are parties to it.

"Studies on biodiversity of Vietnam and Laos" 1998-2005: examining the impact.

The impact of the University of Illinois at Chicago-based Vietnam-Laos International Cooperative Biodiversity Group (ICBG) Program "Studies on Biodiversity of Vietnam and Laos", which has been in operation for the period of 1998-2005, touches on five major areas of endeavor: (a) biodiversity inventory and conservation; (b) studies on medicinal plants; (c) drug discovery and development; (d) economic development; and (e) issues on intellectual property rights and benefit sharing in natural products drug discovery and development. Highlights are presented and the significance is discussed.
