• Abstract

  Nanotechnology has been highlighted due to the fascinating properties of nanomaterials and their applications. Its obtainment is possible by physical, chemical and biological methods (plants and microorganisms). The search for ecologically benign and financially viable technologies has made possible the expansion of studies in the area of biosynthesis, since the other means of obtaining a…

  Syntheses of zinc oxide and silicon oxide nanoparticles from microorganisms, AP.R

• Abstract

  Part I of this Regular Research Grant project will study a class of compounds called dihydropyrimidinones (DHPMs), which are known to have a variety of biological properties. Thus, synthetic methodologies will be developed with the purpose of obtaining numerous racemic DHPMs, most of them unpublished in the literature. These compounds will undergo biological assays concerning the negligib…

  Biginelli reaction (synthesis and chemoenzymatic resolution) and biotransformation of steroids by microorganisms, AP.R

• Abstract

  In this project enzymatic reactions will be applied in aminolysis and synthesis of halohydrins using commercial enzymes. Also agrochemical biodegradation reactions will be investigated. Biotechnologically the reactions catalyzed by lipases can be used in the synthesis of amides and grease molecules with antioxidant properties, as well as in the preparation of chiral drugs using halohydri…

• Abstract

  Enantiomerically pure compounds have importance mainly in the pharmaceutical area since different enantiomers can have different biological activities. Through the enzymatic kinetic resolution of racemates, biocatalysis is a promising alternative in the enantiomeric enrichment of chiral compounds through more sustainable routes, with lipases being the most explored enzymatic class. Theref…

  Synthesis of 1,2,3-triazoles from enantioenriched intermediates by enzymatic kinetic resolution, BP.IC

• Abstract

  The large-scale use of contraceptives has generated an increase in the discharge of steroids into water bodies, especially in locations where there are large concentrations of population. Water and sewage treatment plants do not have efficient mechanisms for the elimination of organic molecules in low concentrations. In this way, compounds such as progesterone and desogestrel, used as con…

• Abstract

  In Brazil, citrus cultivation is of great importance in the country's economy. Only in the 2015/2016 harvest, Brazilian exports of concentrated orange juice totaled 1,080,938 tons. In this context, the use of agricultural pesticides in the orange crop stands out, because in 2016 the agricultural pesticides sector reached US $ 9.56 billion in sales in Brazil. Although pesticides reduce the…
