“…The UV-Vis spectra of the AgNPs band occur near 420 nm is shown in (Fig.2) indicating the formation of AgNPs due to reduction of silver ions by active molecules present in the seed extract. In accordance with previous literature studies were also reported by many researchers 17,18 . The brown color confirms that it was due to the reduction of Ag + which indicates the formation of AgNPs.…”

Here, we explored the medicinal uses of the novel biogenic silver nanoparticles of Eugenia uniflora L. (E. uniflora) seed extract as a cost effective, eco-friendly, reducing and stabilizing compounds. This study describes the synthesis of silver nanoparticles from Eugenia uniflora L. (E. uniflora) seed extract and their antioxidant, antibacterial and cytotoxic potential. Biosynthesis of AgNPs was monitored by UV-visible spectroscopy which revealed intense surface plasmon resonance bands at 447 nm and X-ray diffraction were employed to identify various functional groups and crystalline nature of AgNPs. Scanning electron microscopy studies demonstrated that synthesized particles were crystalline in nature with average size of 78-100nm. In vitro antioxidant effects were analyzed by butylated hydroxytoluene (BHT)) and 2,2-diphenyl-1-picrylhydrazyl (DPPH), which exhibited antioxidant activity there in the particles could scavenges the stable free radical DPPH of 75% to that o positive control BHT. The value of 50% inhibition concentration (IC50) of Standard BHT is 65.55 and E. uniflora is 38.63µg/ml. The antibacterial activity of green AgNPs displayed better zone of inhibition against selected human pathogens. The present study also investigated the toxicity effect of biogenic AgNPs against human prostate cancer cells (PC-3) and the inhibitory concentrations (IC50) were found to be 6.25μg/ml, respectively. It could be concluded that E. uniflora seed extract AgNPs can be used efficiently for potential antioxidant, antibacterial and cytotoxic potential AgNPs with potent biomedical applications.

We disclose microemulsions (ME) of curcumin (CUR) with docosahexaenoic acid (DHA)-rich oil (CUR DHA ME) for targeted delivery to the brain. MEs of CUR (5 mg/mL) with and without DHArich oil (CUR Capmul ME) suitable for intravenous and intranasal administration exhibited negative zeta potential, globule size 520 nm and good stability. Following intravenous delivery MEs exhibited high brain concentration with CUR DHA ME exhibiting a 2.8-fold higher C max than CUR solution. Furthermore, high and sustained concentration was demonstrated even at 24 h, which was 8-and 2-fold higher than CUR solution and CUR Capmul ME, respectively. Brain concentrations following intranasal administration were, however, substantially higher as evident from higher C max and AUC and sustained compared to corresponding intravenous formulations signifying nose to brain targeting. The high brain concentration of CUR DHA ME is ascribed to the targeting efficiency enabled by DHA-mediated transport across the blood-brain barrier (BBB). Histopathological and nasal toxicity confirmed safety of the MEs. Concentrationdependent cytotoxicity in vitro, on human glioblastoma U-87MG cell line was observed with CUR DHA MEs and with the blank DHA ME, implying anticancer potential of DHA. The dramatically low IC 50 value of CUR DHA ME (3.755 ± 0.24 ng/mL) is therefore attributed to the synergistic effect of CUR and DHA in the ME. The CUR concentration achieved with CUR DHA ME at 24 h which translated to 466-fold(intranasal) and 421-fold (intravenous) the IC 50 value in the U-87MG cell line suggests great promise of CUR DHA ME for therapy of brain cancer by both routes.
