“51 highly cross-linked cyclodextrin-based polyurethanes were produced using a high-throughput synthesis method. The reaction

was carried out in a multiwell plate using three different cyclodextrins, namely alpha-, beta- and gamma-cyclodextrin, four different diisocyanate crosslinkers (1,4-phenylene diisocyanate, toluene 2,4-diisocyanate, isophorone diisocyanate, and hexamethylene diisocyanate), and four different carboxyl-containing dihydroxy monomers (2,2-bis(hydroxymethyl)propionic acid, 2,5-dihydroxybenzoic HDAC inhibitor acid, 2,5-dihydroxyterephthalic acid, and 1,4-dihydroxy-2-naphthoic acid). The interactions of the produced polyurethanes with a mixture of molecules of interest, namely acetaminophenol, atenolol, caffeine, ofloxacin, ciprofloxacin, tetracycline, sulfamethoxazole, chloramphenicol, (+/-)-propranolol and diclofenac,

were studied in water. It was demonstrated that the binding properties of the produced polyurethanes could be tuned by selecting the monomers and crosslinkers used for their synthesis. In addition to the hydrophobic inclusion of the target into the cyclodextrin macrocycle, a set of synergistic interactions were shown to BLZ945 manufacturer influence the sorption behavior of the produced polyurethanes. Two selected formulations were upscaled at the gram quantity; the binding results showed a similar behavior as that of the polyurethanes produced using the high-throughput method, thus demonstrating the suitability of the method to produce polymers with enhanced molecular recognition properties.”
“We fabricated 3-dimensional scaffolds consisting of biodegradable poly(D, L-lactide-co-glycolic acid)(PLGA)(75/25) with hydroxyapatite particles containing atelocollagen (aAC). The aim of this study was to evaluate this new type of scaffold in regard to its basic properties and biocompatibility. Characterization

of the obtained scaffolds was performed to know the porosity, shrinkage, diametral tensile strength, and biocompatibility. Composite scaffolds made of PLGA with hydroxyapatite particles NVP-LDE225 datasheet containing atelocollagen (PL-aAC) showed a greater strength and stability than PLGA scaffolds. PL-aAC also exhibited superior performance in terms of cell attachment and proliferation as compared to PLGA, while histological findings showed that PL-aAC had an excellent response toward soft tissues. Our results strongly suggest that PL-aAC is more useful for cell transplantation as compared to PLGA for bone tissue engineering.”
