Condensation of 4-azafluorene with ?-butylene glycol and glycerin

open access: yesChemistry of Heterocyclic Compounds, 1986
1,4-Di (4-azafluoren-9-yl) butane and 9-(δ-hydroxybutyl)-4-azafluorene were obtained by condensing 4-azafluorene with γ-butylene glycol. From the first of these products, 1,4-di(7-aza-3-oxo-1,2,3,10b-tetrahydrofluoranthen-10b-yl)butane was synthesized by a series of successive transformations (cyanoethylation, hydrolysis, dehydrocyclization).

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids

open access: yesLipids, EarlyView.
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

An elastic second skin [PDF]

open access: yes, 2015
We report the synthesis and application of an elastic, wearable crosslinked polymer layer (XPL) that mimics the properties of normal, youthful skin. XPL is made of a tunable polysiloxane-based material that can be engineered with specific elasticity ...

Antibacterial and antifungal properties of propylene glycol, hexylene glycol, and 1,3-butylene glycol in vitro.

open access: yesActa Dermato-Venereologica, 1991
The antimicrobial properties of three glycols, - propylene glycol, hexylene glycol, and 1,3-butylene glycol - against Candida albicans, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes A, Streptococcus mitis, and E. coli were studied in vitro. Within 20 h, 10% and 30% hexylene glycol in fresh tryptic soy broth were able to kill

Mono‐ and Bivalent Poly(iso‐butylene)‐Alanines for Drug‐Delivery of Nimodipine and Triamcinolone Acetonide

open access: yesMacromolecular Rapid Communications, EarlyView.
Mono‐ and bivalent‐, alanine‐modified poly‐iso‐butylenes, folding into beta‐sheets, were prepared by living carbocationic polymerization and subsequent endgroup modification. These PIB‐conjugates are useful as solid polymers for the drug release of triamcinolone and nimodipine. ABSTRACT Poly‐iso‐butylene (PIB) is a well known biocompatible polymer with
