Short X···N Halogen Bonds With Hexamethylenetetraamine as the Acceptor

2021

Hexamethylenetetramine (HMTA) and N-haloimides form two types of short (imide)X···N and X–X···N (X = Br, I) halogen bonds. Nucleophilic substitution or ligand-exchange reaction on the peripheral X of X–X···N with the chloride of N-chlorosuccinimide lead to Cl–X···N halogen-bonded complexes. The 1:1 complexation of HMTA and ICl manifests the shortest I···N halogen bond [2.272(5) Å] yet reported for an HMTA acceptor. Two halogen-bonded organic frameworks are prepared using 1:4 molar ratio of HMTA and N-bromosuccinimide, each with a distinct channel shape, one possessing oval and the other square grid. The variations in channel shapes are due to tridentate and tetradentate (imide)Br···N coordi…

Spray dried hyaluronic acid microparticles for adhesion controlled aggregation and potential stimulation of stem cells

2017

Spray-dried microparticles of a derivative of hyaluronic acid (HA) have been engineered to obtain a controlled aggregation with Human Mesenchymal Stem Cells (hMSCs) into 3D constructs. We demonstrated the utility of chemical functionalization of a native constituent of the extracellular matrix to improve processing performances and to control on stem cell adhesion and differentiation. Native hyaluronic acid (HA), cell adhesive peptides (RGD), transforming growth factor β3, dexamethasone are biological agents potentially suitable for chondrogenic stimulation of hMSCS. However unmodified HA suffers of drawbacks in terms of stability and versatility of processing. Functionalization strategies…

Widening use of dexamethasone implant for the treatment of macular edema

2017

Vincenza Bonfiglio, Michele Reibaldi, Matteo Fallico, Andrea Russo, Alessandra Pizzo, Stefano Fichera, Carlo Rapisarda, Iacopo Macchi, Teresio Avitabile, Antonio Longo Department of Ophthalmology, University of Catania, Catania, Italy Abstract: Sustained-release intravitreal 0.7 mg dexamethasone (DEX) implant is approved in Europe for the treatment of macular edema related to diabetic retinopathy, branch retinal vein occlusion, central retinal vein occlusion, and non-infectious uveitis. The implant is formulated in a biodegradable copolymer to release the active ingredient within the vitreous chamber for up to 6 months after an intravitreal injection, allowing a prolonged interval of effica…
