ScFv-h3D6 is known to preclude cytotoxicity of the A(1-42) peptide by removing its oligomers from the amyloid pathway. As is the case for other scFv molecules, the recombinant production of scFv-h3D6 is limited by its folding and stability properties. Here, we show that its urea-induced unfolding pathway is characterized by the presence of an intermediate state composed of the unfolded V-L domain and the folded V-H domain, which suggests the V-L domain as a target for thermodynamic stability redesign. www.selleckchem.com/TGF-beta.html The modeling of the 3D structure revealed that the V-L domain, located at the C-terminal of the molecule, was ending before its latest -strand was completed. Three elongation mutants,
beyond V-L-K107, showed increased thermodynamic stability and lower aggregation tendency, as determined from urea denaturation experiments and Fourier-transform infrared spectroscopy, respectively. Because the mutants maintained the capability of removing A-oligomers from the amyloid pathway, we expect these traits to increase the half-life of scFv-h3D6 in vivo
and, consequently, to decrease the effective doses. Our results led to the improvement selleck chemical of a potential Alzheimer disease treatment and may be extrapolated to other class-I scFv molecules of therapeutic interest.”
“Aloe ferox Mill. (= A. candelabrum A. Berger), commonly known as the bitter aloe or Cape Smoothened Agonist in vivo aloe, is a polymorphic species indigenous to South Africa. The plant has been used since ancient times as a generic chemopreventive and anti-tumour remedy in folk medicine and it has a well-documented history of use as a laxative. In addition to the plethora of traditional medicinal uses, A. ferox has recently gained popularity as an ingredient in cosmetic formulations and food supplements. Anti-oxidant, antimicrobial, anti-inflammatory, anticancer and antimalarial activities, etc. have been reported. In addition, the ability of Cape aloes to enhance the transport of poorly permeable drugs has enjoyed
recent research interest. Due to its medicinal and commercial importance it has been a popular research topic for natural product scientists who have isolated several chromones and anthrones from the leaf exudate and finished product (bitters). A summary of the historical and modern day uses, commercialisation, chemical composition and biological properties of this coveted ethnomedicinally and commercially important species is presented.
