Synthesis and biological evaluation of pyrrole-2-carboxamide derivatives: oroidin analogues

The reaction of pyrrole or dibromopyrrole-2-trichloroacetone with various amines results in the series of novel pyrrole-2-carboxamide bearing aromatic heterocycle or aryl or alkyl groups. Synthesized molecules were evaluated for their in vitro antibacterial activities. Most of the compounds exhibited potent activity against both Gram-positive and negative pathogens.     

Hydroxyapatite nanorods loaded with parathyroid hormone (PTH) synergistically enhance the net formative effect of PTH anabolic therapy

Parathyroid hormone (PTH) has been a major contributor to the anabolic therapy for osteoporosis, but its delivery to bone without losing activity and avoiding adverse local effects remain a challenge. Being the natural component of bone, use of hydroxyapatite for this purpose brings a major breakthrough in synergistic anabolism. This study focuses on synthesis, characterization and evaluation of in vitro and in vivo efficacy of PTH (1-34) adsorbed hydroxyapatite nanocarrier for synergistic enhancement in the anabolic activity of PTH for bone regeneration. The negative zeta potential of this nanocarrier facilitated its affinity to the Ca²⁺ rich bone tissue and solubilization at low pH enhanced specific delivery of PTH to the resorption pits in osteoporotic bone. In this process, PTH retained its anabolic effect and at the same time an increase in bone mineral content indicated enhancement of the net formative effect of the PTH anabolic therapy.
