Arilsulfonilação tri componente de diidrofurano e ésteres vinílicos via catálise dual níquel/fotorredox
(Universidade Federal de São Carlos, 2022-03-29)
The pursuit of synthetic protocols aligned to sustainability goals, increasingly necessary in the global context in which we operate, caused a great effort by synthetic chemists to develop photocatalytic methodologies ...
Estudo da produção de biopolímeros polihidroxialcanoatos por bactérias isoladas do inseto-praga Diabrotica speciosa
(Universidade Federal de São Carlos, 2023-05-26)
Petroleum-derived plastic materials are fundamental in our daily lives due to characteristics such as strength and durability. However, the indiscriminate use of these materials is one of the main causes of environmental ...

(Universidade Federal de São Carlos, 2023-06-30)
PHYTOCHEMICAL STUDY OF ANNONA SQUAMOSA L. AND BIOLOGICAL ACTIVITIES OF ITS CONSTITUENTS. Annona squamosa L. belongs to the Annonaceae family which is a promising natural source of metabolites with potential therapeutic and ...
Estudos sobre a síntese de derivados do tipo benzoclorinas
(Universidade Federal de São Carlos, 2016-02-18)
Herein, studies about the synthesis of new benzochlorin derivatives
were carried out aiming at the preparation of compounds with special
photophysical properties, such absorption bands between the visible and
near ...
Enzima conversora de angiotensina 1 : purificação, imobilização e bioconjugação
(Universidade Federal de São Carlos, 2015-05-22)
Angiotensin converting enzyme 1 (ACE1) is a dipeptidyl carboxypeptidase that
converts angiotensin I (decapeptide) to a vasoconstrictor octapeptide angiotensin
II. Thus, ACE presents an important role in blood pressure ...
Abordagens sintéticas visando a preparação de bacterioclorinas de alta conjugação
(Universidade Federal de São Carlos, 2016-02-12)
Bacteriochlorins are porphyrin derivatives containing two reduced
peripheral double bonds (FIGURE 1). These compounds present, as their main
properties, intense absorption bands close to the Near Infrared (NIR, 750-900
nm) ...
Padronização de extratos de folhas de amoreira com potencial fitoestrogênico para uso no tratamento dos sintomas do climatério
(Universidade Federal de São Carlos, 2015-08-13)
Mulberry leaves are commonly used by women to alleviate hot flashes, shivering and night sweats. These symptoms appear due to the irregular
estrogen secretion by ovaries during climacteric and are often alleviated using ...
Estudo químico do fungo Memnoniella levispora : busca por metabólitos secundários inibidores da Phytophtora nicotianae
(Universidade Federal de São Carlos, 2015-03-19)
Among the various diseases which attack citrus worldwide, the gummosis is caused by species of the genus Phytophthora. The various species
present in the literature, the most severe in Brazil is P. nicotianae. This pathogen ...
Técnicas de bioinformática aplicadas ao estudo de poligalacturonases de fungos
(Universidade Federal de São Carlos, 2012-04-18)
Plant cell walls are composed of approximately 65% cellulose microfibrils and pectin. The latter is proteolytically degraded by the so-called pectinases enzymes (also known as pectinolytic enzymes). Pectinases may be either ...
Metátese de fechamento de anéis de derivados da R-(-)- Carvona
(Universidade Federal de São Carlos, 2012-03-21)
In this work was developed a new synthetic route to obtain cicloeptenone not conjugated selectively, through a faster and simpler methodology, and in accordance with good practices of green chemistry. By experimental ...
