SEATTLE, July 31, 2012 (GLOBE NEWSWIRE) -- Plandai Biotechnology, Inc. (OTCBB:PLPL), a producer of highly bioavailable plant extracts, today announced recent test results support the use of catechins in preventing the spread of HIV. The report, published in Clinical Immunology, states that four catechins with the galloyl moiety, including catechin gallate (CG), epigallocatechin gallate (EGCG), gallocatechin gallate (GCG), and epicatechin gallate (ECG), were found to effectively inhibit HIV-1 integrase. Integrase is the enzyme produced by a virus that allows it to be integrated into the infected cell. Inhibiting integrase is seen as a key component in preventing the spread of retroviruses such as HIV.
