Highlights of current research:
ICBG - International Cooperative Biodiversity Group Program
Since 1998, I have been involved in an international collaborative research program called ICBG (International Cooperative Biodiversity Group program) as its Principal Investigator, with member-institutions located at my own institution (UIC), in Vietnam (Institute of Biotechnology/IBT, Institute of Chemistry/ICH, Institute of Ecology and Biological Resourceces/IEBR of the National Center for Science and Technology/NCST, Hanoi; Cuc Phuong National Park/CPNP, Ninh Binh), in Laos (Traditional Medicine Research Center/TMRC, Vientiane), and in UK (Glaxo Wellcome/GW, now Glaxo Smith Kline/GSK). The specific aims of this program are (1) to study plant diversity at Cuc Phuong National Park and medicinal plants of Laos, (2) to search for biologically active molecules from plants of these two countries as potential candidates for drug development (cancer, AIDS, malaria, tuberculosis, Alzheimer disease, pain), and (3) to promote economic development among members of communities in the areas where the ICBG research is undertaken, as well as to strengthen the scientific capacity and the infrastructure of the ICBG host institutions. To know more about my work, visit http://uic-icbg.pharm.uic.edu. This ICBG research is supported, in part, by Grant 1-UO1-TW01015 (1998-2003), International Cooperative Biodiversity Groups Program, through funds from NIH, NSF, and Foreign Agricultural Service of the USDA.

NCI-Sponsored Plant Explorations (Southeast Asia)
For the past 16 years, I have had the privilege of running a plant exploration program under the sponsorship of the National Cancer Institute (NCI). The focus of the program is the tropical rain forests of Southeast Asia, from Bangladesh east to Papua New Guinea. The objective is to collect plants based on taxonomic diversity approach for screening against cancer (and later, AIDS) at the laboratory of the NCI. The exploration program started in 1986, with collections undertaken heavily in Malaysia, the Philippines, Indonesia, and Papua New Guinea. Operation shifted to Indochina in 1996, to this day, although plant collections in Papua New Guinea continues. A team of many botanists (US-based and those based in the country of collections) have taken part in this program. This program has been implemented under NCI contracts with the University of Illinois at Chicago and under a Memorandum of Agreement between the NCI and host-country institutions and with permits from respective government authorities. To date, more than 17,000 plant samples of angiosperms have been collected (comprising 3000-3500 species) and delivered to NCI. The success of the program is reflected in the collection of samples of Calophyllum lanigerum (Guttiferae) tree in a tropical rain forest of Sarawak (Malaysia) in 1987, from which the NCI scientists discovered the anti-HIV compound Calanolide A, a coumarin class of compound, currently under clinical trials phase I/II by Sarawak-MediChem Pharmaceuticals, Inc. (http://www.sarawak-medichem.com/). In 1992, a second species, Calophyllum teysmannii, was discovered, yielding Calanolide B, currently under preclinical trials at the same company. This NCI contract is re-competed every 5 years; following a successful re-competition in 2000, this plant exploration program continues to operate through 2006. This program is funded through NCI Contracts NO1-CM-67925 (1986-1991), NO1-CM-17 (1991-1996), NO2-CM-67255 (1996-2001), and NO2-CM-17013 (2001-2006).

Plot-based Drug Discovery Effort
In 1989, I initiated an experiment of collecting plants in the NCI drug discovery program by setting up a 1-hectare plot in a tropical rain forest in Palawan, Philippines. In this process, plant samples were collected from marked and numbered trees of a certain minimum diameter. Every collection was documented by voucher herbarium specimens as basis for taxonomic identification. Two species (of about 150 species of trees) in that plot turned out active in the anti-HIV tests. With other faculty members and with our graduate students in pharmacognosy, we extended this plot design with more plot-based plant drug screening from the forests of Philippines, Costa Rica, Panama, the Dominican Republic, USA (tropical Florida) and Vietnam. Two compounds with antiplasmodial activity, methyl gallate and methyld digallate, were isolated from Swintonia foxworthyii (Anacardiaceae) and a new cytotoxic compound, ardisenone, was isolated from Ardisia iwahigensis (Myrsinaceae), both species from plots in Philippine forests; a novel antiplasmodial alkaloid, costaricine, was isolated from Nectandra salicifolia (Lauraceae) from a plot in the forest of Costarica; an antimicrobial biphenyl neolignan was isolated from Caryodaphnopsis tonkinensis (Lauraceae) from a plot in a tropical rain forest of Vietnam. A plot-based drug testing of plants from a 1-hectare plot in a tropical rain forest of the Barro Colorado Island (Panama) found that of 40 selected for testing, 12 showed activity in one or more of the 11 bioassay systems used (anticancer, anti-HIV, antimalarial, and cancer chemopreventive assays). Work is on-going in the isolation on new anticancer agents from plants from plots set down in the hardwood hammocks of southern Florida. Plot-based drug discovery research has been supported through funds from the NCI contract, the NCDDG grant, a NIH antimalarial grant, and a grant from the MacArthur Foundation.

Stevia Research
As part of studies in the search for high-intensity sweetening agents from plants at PCRPS, I traveled to Paraguay and a number of Latin American countries in the early 1980's to carry out field surveys and interviews on sweet-tasting plants, as well as to acquire plant materials of such species for laboratory studies at PCRPS. One particular plant became the focus of my research, namely, Stevia rebaudiana (Bertoni) Bertoni. Two papers resulted from this effort. Funding for the field studies in the Stevia research was provided from a grant from the National Institute of Dental Research (A.D. Kinghorn, Principal Investigator).
