• Abstract

  This project is divided into two main parts. In both of them, the methodologies to be used will be basically the same. 2D- and 4D-QSAR studies (studies of quantitative relationships between chemical structure and biological activity) will be developed. They vary specifically with respect to areas of application. In one case, a study of the biological activity of derivatives of 1.4-naphtho…

  Theoretical Studies of bioactive substances Molecular modeling and QSAR (2D and 4D) studies of: A) 1,4 Naftoquinones derivatives with Antileucemic activity. B) Herbicides 3-benzil-5-arilidenofuran-2(5H)-one and Trifluoromethyl Arylamides, AP.R

• Abstract

  This project consists of two stages; one of basic research and the other of applied research. In the basic research the central focus is the advanced use of chemiometry in theoretic studies of biological systems, including the modification of known methods and the introduction of new chemiometric techniques. These methods are: QSAR, QSPR, structural chemiometry, IQSAR, higher order method…

• Abstract

  Papaya (Carica papaya) is a fruit widely consumed worldwide due to its pleasant taste and high nutritional value. Brazil stands out as one of the largest papaya producers in the world, and exports have grown significantly in recent years. However, large losses of fruits are frequent due to the occurrence of phytosanitary problems, such as diseases caused by post-harvest fungi, causing a h…
