Ultrasound-assisted synthesis of 1,4-dihydropyridine derivatives by an efficient volcanic-based hybrid nanocomposite

RETRACTED: Multi‐Stimuli Nanocomposite Therapeutic: Docetaxel Targeted Delivery and Synergies in Treatment of Human Breast Cancer Tumor

“…Previously, we have reported several magnetic systems in micro‐ and nanoscale for diverse functional applications. [ 17–24 ] To further expand upon this work, we utilized one of the most commonly employed polymers, polyvinyl alcohol (PVA), to encapsulate magnetic Fe 3 O 4 NPs by virtue of its extended hydrogen bonding and to provide a selective release medium for DXL. [ 25 ] Drug molecules, such as DXL, can be incorporated into a PVA gel when polymer chains are in a shrunk state at low temperatures, and subsequently released in a target tissue upon a PVA transition into a swollen gel at 37 °C.…”

Highly porous copper-supported magnetic nanocatalysts: made of volcanic pumice textured by cellulose and applied for the reduction of nitrobenzene derivatives

“…28 The synthesized composite is notable even in terms of mechanical properties because it is a stable hybrid structure. 29,30 As mentioned earlier, the synthetic heterogeneous catalytic composite in this work is suitable for scaling up and industrial applications because of its high biocompatibility and because it is made from components found in abundance in nature. In this work, aer pumice, as an inorganic base with -OH groups functions as a suitable host for cellulose, as an organic base, Cu 2+ ions are added to the system to act as catalytic sites to reduce the nitro functional groups of different compounds to amines aer their conversion to Cu.…”

Antimicrobial therapeutic enhancement of levofloxacin via conjugation to a cell‐penetrating peptide: An efficient sonochemical catalytic process

“…Concisely, ultrasonication leads to obtain high reaction yield during a short reaction time, under a milder condition. Moreover, physical properties like well dispersion is effectively enhanced by ultrasonication 21–25 . In this study, we intend to introduce a convenient synthetic strategy for a novel medicinal conjugation including CPP hexapeptide and LVX, which passes through a comparative viewpoint between two different heterogeneous magnetic catalytic systems.…”
