Copaiba's traditional uses as an antiseptic for sore throat, upper respiratory and urinary tract infections can be explained partly by the resin's antibacterial properties documented in the 1960s and 1970s. Researchers again confirmed (in 2000 and 2002) that the resin as a whole (and, particularly, two of its diterpenes-copalic acid and kaurenic acid) demonstrated significant antimicrobial activity against gram-positive bacteria. One of copaiba's other chemicals, kaurenoic acid, has also demonstrated selective antibacterial activity against Gram-positive bacteria in other recent studies.

Another recent area of research on copaiba resin has focused on its anticancerous and antitumor properties. Researchers in Tokyo isolated six chemicals (clerodane diterpenes) in the oleoresin of copaiba in 1994 and tested them against carcinomas in mice to determine their antitumor activity. One particular compound, called kolavenol, was twice as effective at increasing the lifespan in mice with carcinomas (by 98%) as the standard chemotherapy drug, 5-Fluorouacil (5-FU). The natural resin also increased lifespan by 82% - which was still higher than 5-FU (which increased lifespan by 46%). Interestingly, the tests provided better anti-tumor effects than in previous test-tube studies. The Spanish team of researchers that documented copaiba's antimicrobial effects in 2002 also tested for antitumor effects. These scientists reported that another phytochemical in the resin, methlyl copalate, had activity against human lung carcinoma, human colon carcinoma, human melanoma, and mouse lymphoid neoplasm cell lines. Brazilian researchers reported in 2002 that one of copaiba's active chemicals, kaurenoic acid, also inhibited the growth of human leukemic cells by 95%, and human breast and colon cancer cells by 45% in vitro. Kaurenoic acid can comprise as much as 1.4% of the natural copaiba oleoresin.

Hexane and chloroform extracts exhibited comparable antimicrobial activity with the standard.

Abstract:
There is much current interest in the use of solar light for the generation of hydrogen from water. Most of the systems reported so far use a sacrificial electron donor that cannot be employed in real applications. The efficiencies of hydrogen generation in the absence of any sacrificial agent resulting in the simultaneous generation of hydrogen and oxygen in the corresponding stoichiometry is considerably more difficult. In this presentation, I will present data showing the photocatalytic properties of oriented Cu2O nanoplatelets (3-5 nm thick, 20-40 nm lateral dimensions) strongly grafted on graphene is a highly efficient photocatalyst for this process.1 The oriented Cu2O nanoplatelets on graphene are obtained by pyrolysis at 900 ºC under Ar of chitosan containing Cu2+ salts. The ability of chitosan to adsorb large concentrations of transition metal salts and to be a precursor of graphene materials is of crucial importance in the preparation of this highly active photocatalyst and responsible for its properties.

Thesis On Antimicrobial Activities Of Medicinal Plants

Abstract:
Biofilms are three-dimensional structures that contains billions of genetically identical bacteria submerged in a self-produced extracellular matrix, which protect bacteria from antibiotics and the human immunological defenses. More than 85 % of chronic and/or recurrent human infections are linked to bacterial biofilms. In addition, spore-forming pathogenic bacteria represent an additional community threat because of their intrinsic refractory behavior against antibiotics, phagocytes and their easy utilization in bioterrorist attacks. Therefore, every day the available microbicide arsenal against biofilms and spores becomes scarcer. Accordingly, nano-material biotechnology emerges as a promising alternative for reducing the detrimental effects of microbial-related diseases. Here we describe the development of novel nanostructured coating systems with improved photocatalytic and antibacterial activities. These systems comprise, in one case, layers of SiO2 followed by layers of mesoporous or dense TiO2-anatase, and doping with silver nanoparticles (Ag NPs). In the other case, we developed Copper NPs and its oxides by a chemical method based on a bottom up approach and its stabilization using aminosilanes as surface modifiers. The activity of CuNPs and AgNPs (MNPs) was measured against spores and vegetative (planktonic and sessile) forms of the relevant human pathogens Enterohemorrhagic Escherichia coli (etiological agent of Hemolytic Uremic Syndrome), Listeria monocytogenes (etiological agent of septic abortion), Bacillus anthracis (etiological agent of Anthrax), Clostridium perfringens (etiological agent of food-associated diarrhea and Gas Gangrene), cystic-fibrosis related Pseudomona aeruginosa and methicillin-resistant Staphylococcus aureus ( etiological agent of sepsis and myocardiopathies). The planktonic and sessile growth (measured as the final cellular yield at 600 nm and crystal violet staining, respectively) of each pathogen, as well as the sporocide effect on C. perfringens and B. anthracis spores, was very significant at submillimolar concentrations of MNPs (95 % of vegetative growth inhibition and sporocide effect, p
