Angiotensin (1-7) (Ang-(1-7)) is a bioactive heptapeptide with a short half-life and has beneficial effects in several tissues - among them, skeletal muscle - by preventing muscle atrophy. Dendrimers are promising vehicles for the protection and transport of numerous bioactive molecules. This work explored the use of a neutral, non-cytotoxic hydroxyl-terminated poly(amidoamine) (PAMAM-OH) dendr...

Fucoxanthin, an allenic carotenoid, is abundant in macro and microalgae as a component of the light-harvesting complex for photosynthesis and photo protection. This carotenoid has shown important pharmaceutical bioactivity, exerting antioxidant, anti-cancer, anti-diabetic, anti-obesity, anti-photoaging, anti-angiogenic, and anti-metastatic effects on a variety of biological models. This caroten...

Polycyclic indole moieties are often part of bioactive natural or synthetic products, however traditionally have to be synthesized over several steps involving time consuming sequential multi-step syntheses. We herein communicate an efficient and flexible 2-step procedure to complex multicyclic indole alkaloid-type compounds involving Ugi MCR and Pictet-Spengler reaction.

Abstract — Fe2O3 substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. Nucleation and crystallization regimes were determined by the parameters obtained from differential thermal analysis (DTA) of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified u...

Pseudomonas mesoacidophila ATCC 31433 is a Gram-negative bacterium, first isolated from Japanese soil samples, that produces the monobactam isosulfazecin and the β-lactam-potentiating bulgecins. To characterize the biosynthetic potential of P. mesoacidophila ATCC 31433, its complete genome was determined using single-molecule real-time DNA sequence analysis. The 7.8-Mb genome comprised four rep...
