First insights into insecticidal activity against Aedes aegypti and partial bio...
Almeida Filho, Luiz C. P.; Tabosa, Pedro M. S.; Hissa, Denise Cavalcante; Vasconcelos, Ilka M.; Carvalho, Ana F. U.BACKGROUND: Arboviroses such as dengue, Zika and chikungunya represent a serious public health issue as a consequenceof the absence of approved vaccines or specific antiviral drugs against the arboviruses that cause them. One way to preventthese diseases is by combating the vector mosquito, Aedes aegypti (Diptera), which has serine proteases in the midgut. Proteaseinhibitors are molecules that can block enzyme a...
A trypsin inhibitor purified from Cassia leiandra seeds has insecticidal activi...
Dias, Lucas P.; Oliveira, Jose T. A.; Rocha-Bezerra, Lady C. B.; Sousa, Daniele O. B.; Costa, Helen P. S.; Araújo, Nadine M. S.; Carvalho, Ana F. U.A trypsin inhibitor from Cassia leiandra seeds, named ClTI, was purified, characterized, and its insecticidal activity against Aedes aegypti evaluated. ClTI was purified by DEAE-Cellulose and trypsin-Sepharose 4B chromatography, with a 15.5-fold purification and 2.4% yield. ClTI is composed of a 19,484 Da polypeptide chain as revealed by mass spectrometry, it is not a glycoprotein, its amino acid sequence is si...
Nutritional study of two Brazilian soybean (Glycine max) cultivars differing in...
Vasconcelos, Ilka M.; Maia, Andrea A. B.; Siebra, Elisângela A.; Oliveira, José T. A.; Carvalho, Ana F. U.; Melo, Vânia M. M.; Carlini, Célia R.The research was conducted with two different recently released Brazilian soybean cultivars (Rio Balsas and Bays) to evaluate whether there is any correlation between the different levels of antinutritional and/or toxic proteins in the cultivars and their nutritive value as sources of protein for monogastric animals (rats). Furthermore, it is discussed, for the first time, the role of the dietary soyatoxin on t...
Puri®cation of a novel antibacterial and haemagglutinating protein from the pur...
Melo, Vânia M. M.; Duarte, Ana B. G.; Carvalho, Ana F. U.; Siebra, Elisângela A.; Vasconcelos, Ilka M.Physicochemical characterisation and antibacterial and haemagglutinating properties of a new protein isolated from purple fluid of the Aplysia dactylomela are reported. The purification procedure consisted basically of ammonium sulphate fractionation, ion exchange, exclusion molecular and hydrophobic interaction chromatography. The highly purified protein, designated dactylomelin-P, is a single chain protein of...
