That\u0027s because counterfeiters sometimes include small quantities of the real drug in their fakes, possibly as part of an effort to fool simple quality tests.  By not killing the malaria parasites, the small amount could facilitate development of drug resistance.\n\u003C\/p\u003E\n\u003Cp\u003EAs their part of the investigation, Georgia Tech researchers used sensitive mass spectrometry techniques to analyze nearly 400 drug samples provided by public health authorities.  They also developed methods to speed up analysis, including an ionization process that reduced the time required to test a drug sample from half an hour to just a few seconds. \n\u003C\/p\u003E\n\u003Cp\u003EActivities aimed at addressing the widespread problem of counterfeit anti-malarial drugs were reported February 12th in the journal \u003Cem\u003EPLoS Medicine\u003C\/em\u003E.  Georgia Tech\u0027s efforts to develop faster analytical techniques were sponsored by the U.S. National Science Foundation, while the sample analysis was supported by a small grant from WPRO\/WHO.\n\u003C\/p\u003E\n\u003Cp\u003EMalaria kills more than a million people each year worldwide, and is a risk for about 40 percent of the world\u0027s population.  Most victims would survive - if they had access to the proper drugs.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022About 50 percent of the samples obtained from the field in Southeast Asia were fakes,\u0022 said Facundo Fernandez, an analytical chemist and assistant professor in Georgia Tech\u0027s School of Chemistry and Biochemistry.  \u0022They look very real, even down to the hologram in the packaging.  It\u0027s very difficult to tell which ones are the fakes and which ones are real.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EWhen Fernandez began analysis of the drug samples, he assumed that they would not include any real active ingredients.  But his graduate students Christina Hampton and Leonard Nyadong soon discovered that the counterfeiters were making their fake anti-malarials with a broad range of mostly expired pharmaceuticals.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We found old and ineffective anti-malarials like chloroquine,\u0022 he said.  \u0027We found antibiotics like erythromycin.  We found all sorts of drugs that basically have no effect on resistant malaria parasites.  Acetaminophen was one of the most common chemicals we found.\u0027\n\u003C\/p\u003E\n\u003Cp\u003EFernandez speculates that the makers chose certain compounds, like acetaminophen, because they could temporarily make patients feel better by lowering the fever associated with malaria. \n\u003C\/p\u003E\n\u003Cp\u003EMass spectrometry provides a very effective means of identifying samples by determining their accurate molecular weight.  But the conventional analysis can be time-consuming - especially in the preparation of samples.\n\u003C\/p\u003E\n\u003Cp\u003EFernandez and his Georgia Tech group developed a faster method that allows them to analyze hundreds of samples in a single day.  Their goal was to make mass spectrometry analyses responsive within the time constraints that surveys in developing countries and law enforcement agencies involved in anti-counterfeiting tasks require.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022These are methods that let you analyze a solid sample without any significant preparation,\u0022 he explained.  \u0022You can take a tablet, put it in front of the instrument with an ionization source, and you get a quick snapshot of what\u0027s in the sample.  It provides a very high throughput pipeline to identify samples quickly.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EUltimately, Fernandez hopes to help develop high-accuracy instrumental tests that could be used in the field to save the time and expense of shipping suspected fakes to labs.\n\u003C\/p\u003E\n\u003Cp\u003EBeyond the mass spectrometry, the effort also relied on analysis of pollen found in the drugs - a discipline known as forensic palynology - which was done by scientists in New Zealand who were part of Operation Jupiter.  A study of calcium carbonate isotopes in the compounds, together with the pollen and active ingredients in the samples, pointed to two main groups of samples originating in different geographic regions of Asia.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This is absolutely CSI - the techniques they use on the television program really do work in real life,\u0022 Fernandez said.\n\u003C\/p\u003E\n\u003Cp\u003EThe Operation Jupiter team provided enough information that Chinese authorities were able to shut down the manufacturers, which were sophisticated operations able to accurately mimic the packaging and holographic seals of legitimate pharmaceutical companies.\n\u003C\/p\u003E\n\u003Cp\u003EFernandez and his students remain involved in anti-counterfeiting activities and hope to obtain additional funding to continue supporting the efforts.  They are now investigating fake anti-malarials sold in Africa, analyzing assortments of drugs sold in markets there, and studying other faked drugs, such as tamiflu.\n\u003C\/p\u003E\n\u003Cp\u003EFernandez got involved in the project in 2003 because of a chance encounter with Michael Green, a parasitic disease specialist at the CDC.  He soon began working with Green and with Paul Newton, a physician from the University of Oxford in the United Kingdom who is based in Laos.\n\u003C\/p\u003E\n\u003Cp\u003ELarge pharmaceutical companies can afford to pursue counterfeiting themselves, Fernandez noted, but in many cases, drugs sold for use in developing nations come from small companies that cannot afford private investigators and law firms to go after the counterfeiters.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022The problem is not over,\u0022 he cautioned.  \u0022There are more fakes and more fake producers.  But at least this is a beginning.  Having an opportunity to do some good in this area is very satisfying.\u0022\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\nGeorgia Institute of Technology\u003Cbr \/\u003E\n75 Fifth Street, N.W., Suite 100\u003Cbr \/\u003E\nAtlanta, Georgia  30308  USA\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contacts\u003C\/strong\u003E: John Toon (404-894-6986); E-mail: (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E) or Abby Vogel (404-894-3364); E-mail: (\u003Ca href=\u0022mailto:avogel@gatech.edu\u0022\u003Eavogel@gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ETechnical Contact\u003C\/strong\u003E: Facundo Fernandez (404-385-4432); E-mail: (\u003Ca href=\u0022mailto:facundo.fernandez@chemistry.gatech.edu\u0022\u003Efacundo.fernandez@chemistry.gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: John Toon\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"New techniques developed to test suspected fake anti-malarials"}],"field_summary":[{"value":"Georgia Institute of Technology researchers were part of a three-continent, multi-organizational effort known as \u0027Operation Jupiter\u0027 that successfully identified and shut down manufacturers who were flooding Southeast Asia with counterfeit - and ineffective - anti-malarial drugs.","format":"limited_html"}],"field_summary_sentence":[{"value":"Researchers were part of int\u0027l. anti-counterfeiting effort"}],"uid":"27303","created_gmt":"2008-02-13 01:00:00","changed_gmt":"2016-10-08 03:03:24","author":"John Toon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2008-02-13T00:00:00-05:00","iso_date":"2008-02-13T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"hg_media":{"71427":{"id":"71427","type":"image","title":"Facundo Fernandez","body":null,"created":"1449177376","gmt_created":"2015-12-03 21:16:16","changed":"1475894637","gmt_changed":"2016-10-08 02:43:57"}},"media_ids":["71427"],"related_links":[{"url":"http:\/\/www.chemistry.gatech.edu\/faculty\/Fernandez\/","title":"Facundo Fernandez"},{"url":"http:\/\/www.chemistry.gatech.edu\/","title":"School of Chemistry and Biochemistry"}],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"141","name":"Chemistry and Chemical Engineering"},{"id":"146","name":"Life Sciences and Biology"},{"id":"135","name":"Research"}],"keywords":[{"id":"7489","name":"anti-malarial"},{"id":"7488","name":"counterfeit"},{"id":"1962","name":"drugs"},{"id":"7490","name":"mass-spectrometry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJohn Toon\u003C\/strong\u003E\u003Cbr \/\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=jt7\u0022\u003EContact John Toon\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-6986\u003C\/strong\u003E","format":"limited_html"}],"email":["jtoon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
