Abstract The aim of this research was transdermal delivery of 5-fluorouracil (5-FU) using dextran-coated cellulose acetate phthalate (CAP) nanoparticulate formulation. CAP nanoparticles were prepared using drug-polymer ratio (1:1 to 1:3) and surfactant ratio (2.5, 5 and 10%). Dextran coating was made using aminodextran. The results showed that the optimized CAP nanoparticles (CNs) and dextran-coated CAP nanoparticles represented core-corona nanoparticles with the mean diameter of 75 ± 3 and 79 ± 2 nm, respectively, and entrapment efficiency was 82.5 ± 0.06 and 78.2 ± 0.12, respectively. Dextran-coated nanoparticles (FDCNs) and CAP nanoparticles (FCNs) showed in vitro 5-FU release upto 31 h and 8 h, respectively. Moreover, the cumulative amount of 5-FU penetrated through excised skin from FDCNs was 2.94 folds than that of the FU cream. Concentration of 5-FU in epidermis and dermis were also studied. In dermis, concentration of 5-FU was found higher in case of FDCN formulation than plain FU cream. FDCNs were found more hemocompatible in comparison to FCNs. The hematological data recommended that FDCNs formulation was less immunogenic compared to FU creams formulation. In blood level study, FDCNs exhibited 153, 12, 16.66 and 16.24-fold higher values for area under the curve, Tmax, Cmax and mean residence time (MRT) compared with those of FU cream, respectively. The in-vitro cytotoxicity was assessed using the MCF-7 by the MTT test and was compared to the plain 5-FU solution. All the detailed evidence showed that FDCNs could provide a promising tuning as a transdermal delivery system of 5-FU.

The present work was focused to evaluate in vitro antioxidant of Pleurotus florida. The hydroethanolic extract was prepared by macerating basidiocarp with water:ethanol (1:1). The antioxidant potential was evaluated by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity, reducing power, chelating effects on ferrous ions, total antioxidant capacity, and lipid peroxidation inhibitory activity. Further total flavonoid and phenolic content was also estimated. The comparison between different antioxidant assays was done by correlation coefficient. The results from the antioxidant assays showed that hydroethanolic extract (HEE) might act as radical scavenger to a certain extent. The distinct scavenging activities of HEE can be due to the diverse phytochemical constituents. Being a rich source of antioxidants, P. florida can be used as an accessible source of natural antioxidants with consequential health benefits.

ABSTRACT Flavonoid-rich fraction and Pongamol (PONG) from Tephrosia purpurea isolated from ethyl alcohol extract by column chromatography were evaluated for wound-healing properties in diabetic rats. The ointments of PONG (0.2 and 0.5% w/w) and flavonoid-rich fraction (5% w/w) were prepared with simple ointment base B.P. An excision wound was made on each streptozotocin-induced diabetic animal, and healing was assessed by determination of protein, hydroxyproline content and antioxidants; superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) levels, and histopathological study. On the twentieth day, the TPF (ethyl acetate fraction of T. purpurea) ointment–treated group showed 100% contraction while the group treated with 0.2% w/w PONG, 0.5% w/w PONG ointment and control showed 84.28%, 96.53%, and 80.14%, respectively. The hydroxyproline, protein content, and enzyme levels (SOD, CAT, and GSH) increased in animals treated with TPF, 0.5% w/w PONG and Povidone iodine ointment USP. Presence of matured collagen fibers and fibroblasts with better angiogenesis was observed in histopathological studies.
