Protopine Production by Fumaria Cell Suspension Cultures: Effect of Light

Protopine biosynthesis in Fumaria rostellata and Fumaria officinalis cell suspensions was investigated. For the first time, we reported for calli and cell suspensions obtained from F. rostellata and F. officinalis. Callus induction was initiated on a Murashige and Skoog medium, supplemented with sucrose and various concentrations of plant growth regulators: 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzylaminopurine (BAP). The best morphological characteristics, growth behavior, and protopine biosynthesis were observed for two callus lines (5FRL14 and 12FOL1) cultivated under submerged conditions, at low concentration of 2,4-D (0.2 and 0.5 mg/L) and higher concentration of BAP (2.0 and 3.0 mg/L). The maximal yield of protopine was accumulated from cell suspension of F. rostellata (line 5FRL14) cultivated under illumination49.6 mg/L. Time courses of utilization of sucrose, ammonium, nitrate, and phosphate ions in cultural liquid and acetylcholinesterase inhibitory activity of alkaloid extracts of studied suspensions are also presented.

Synthesis and evaluation of disulfide bond mimetics of amylin-(1-8) as agents to treat osteoporosis

Osteoporotic fracture is a significant public health problem, resulting in fractures in >50% of women and in almost one third of men age 65 and older. Most of the existing therapies act by slowing bone loss, through inhibiting the action of bone resorbing cells. However, more substantial reductions of fracture numbers will only result from treatments that can rebuild bone. Our own animal studies demonstrated the anabolic potential of the small but unstable octapeptide fragment of amylin-(1-37), namely amylin-(1-8) containing one disulfide bridge (Cys/2 and Cys/7) [Am. J. Physiol. Endocrinol. Metab. 2000, 279, E730]. Herein, we describe the synthesis of amylin-(1-8) octapeptide and seven analogues thereof wherein the disulfide bridge is modified either via insertion of different linkers or bridges of a different nature in order to improve the stability and/or bone anabolic activity of the parent peptide. The peptide analogues were screened for proliferative activity in primary foetal rat bone-forming cells or osteoblasts at physiological concentrations. One such analogue showed promising biological activity.

Magnetic field-assisted alignment of graphene oxide nanosheets in a polymer matrix to enhance ionic conduction

This study aims to elucidate the effect of magnetic graphene oxide (GO) alignment in a polymer matrix on the ionic conduction and methanol barrier properties of the resulting composites. Magnetic iron oxide (Fe3O4) nanoparticles were fabricated and anchored on GO nanosheets. The magnetic GO-Fe3O4 nanofillers were incorporated into a quaternized polyvinyl alcohol (QPVA) matrix to form a polymeric composite. By applying a magnetic field (MF) along the in-plane direction during the drying and film formation steps, the GO-Fe3O4 nanosheets were aligned in an orientation parallel to the direction of the MF and connected to each other in elongated domains, as confirmed using transmission electron microscopy, field emission scanning electron microscopy/energy dispersive X-ray spectroscopy mapping, and laser scanning microscopy. The MF-aligned QPVA/GO-Fe3O4 electrolyte possessed higher conductivity and lower permeability than the un-aligned QPVA/GO-Fe3O4 membrane and pristine QPVA film. The aligned QPVA/GO-Fe3O4 composite exhibited a peak power density of 172.4 mW cm?2 at 60 C, which is higher than those of the composite without the MF treatment (67.7 mW cm?2) and the pristine QPVA (50.3 mW cm?2). This research demonstrates the extraordinary benefits of MF assisted GO-Fe3O4 nanofillers in facilitating the ion conduction and barrier property of a polymeric composite at 0.1% filler loading.
