Characterization, Cytotoxicity and Anti-oxidant Studies of Phytoniosome Loaded with Ethanolic Leaf Extract of Tinospora Cordifolia.

Background: From time immemorial herbal preparations are been employed for the treatment of several ailments. In recent years due to poor bioavailability the conventional herbal preparations are replaced by phytoniosomes, an advanced novel drug delivery system in which the herbal extracts are incorporated into a non-ionic surfactant to yield higher absorption and remarkable desired pharmacological activity. The present study is aimed to prepare and characterize the ethanolic leaf extract of Tinospora cordifolia (nELETC) loaded phytoniosome and to compare its antioxidant properties with ethanolic leaf extract of Tinospora cordifolia (ELETC). Methods: The ethanolic leaf extract and ethanolic leaf extract of Tinospora cordifolia loaded phytoniosome (ELETC and nELETC) were prepared. The characterization of the prepared phytoniosomes were performed by UV-Visible spectroscopy, FTIR, XRD, SEM, TEM, DLS and zeta potential. The nontoxic nature of the prepared phytoniosomes was analyzed using MTT assay in vero cell line. The antioxidant potential of ELETC and nELETC were compared by the scavenging activity of DPPH, Hydrogen peroxide and Superoxide radicals. Results: The formation of ethanolic leaf extract of Tinospora cordifolia loaded phytoniosome (nELETC) was confirmed with UV-Vis spectroscopy. The SEM and TEM images confirmed the spherical shape of the nELETC with average size ranging from 600 to 1800 nm. The zeta potential showed magnitude of -65.55 to -77.83 mV and its crystalline structure was confirmed by XRD analysis. Through the FTIR spectrum presence of alcohols, alkanes, phenols, esters, aliphatic and aromatic compounds as well as alkenes and carbolic acids were identified. MTT assay establishes the non-toxic nature of the synthesized nELETC and excellent antioxidant potential was observed for nELETC than ELETC. Conclusion: In conclusion, the ethanolic leaf extract of Tinospora cordifolia loaded phytoniosome (nELETC) will serve as a promising drug carrier in scavenging the free radicals and can be used in various biological applications.

Role of homeobox d10 gene targeted signaling pathways in cancers.

Homeobox D10 (HOXD10) is a transcription factor from the homeobox gene family that controls cell differentiation and morphogenesis throughout development.Due to their functional interaction, changes in HOXD10 gene expression might induce tumors. This narrative review focuses on how and why the dysregulation in the signaling pathways linked with HOXD10 contributes to the metastatic development of cancer. Organ development and tissue homeostasis need highly conserved homeotic transcription factors from homeobox (HOX) genes. Their dysregulation disrupts regulatory molecule action, causing tumors. The HOXD10 gene is upregulated in breast, gastric, hepatocellular, colorectal, bladder, cholangiocellular carcinoma and prostate cancer. Tumor signaling pathways are affected by HOXD10 gene expression changes. This study examines HOXD10-associated signaling pathway dysregulation, which may alter metastatic cancer signaling. In addition, the theoretical foundations that alter HOXD10-mediated therapeutic resistance in malignancies has been presented. New cancer therapy methods will be simpler to develop with the newly discovered knowledge. This review showed that HOXD10 may be a tumor suppressor gene and a new cancer treatment target signaling pathway.

Comparative Antioxidant and Anti-gout Activities of Citrullus colocynthis loaded Fruit Silver nanoparticles with its Ethanolic extract.

Background: The biological synthesis of silver nanoparticles (AgNPs) using plant materials is a rapidly developing method with several alternative medical applications. This comparative study of ethanolic fruit extract of Citrullus colocynthis (C. colocynthis) (EFECC) and synthesized silver nanoparticles (CC-AgNPs) were carried out for antioxidants and anti-gout arthritic activities. Methods: The AgNPs were synthesized using C. colocynthis fruit and its characterization was done by UV-visible spectroscopy, TEM, XRD and FT-IR. The 90% ethanol was used for extract preparation. Antioxidant activity was analyzed by DPPH and the Hydrogen Peroxide (H2O2) method. In vitro anti-arthritic activity was tested by xanthine oxidase inhibition, protein denaturation and HRBC membrane stabilization assay. Results: The synthesized CC-AgNPs were confirmed by UV-vis spectroscopy and TEM images displayed spherical shapes with 10-45 nm size range. Furthermore, the functional groups and crystalline structure of CC-AgNPs were determined by FT-IR and XRD analysis. The biosynthesized CC-AgNPs exhibited an excellent free radical scavenging ability than EFECC. In anti-arthritic activity, the CC-AgNPs showed effective inhibition of xanthine oxidase production, protein denaturation, and damaged RBC membranes compared to EFECC. Conclusion: The antioxidant activities and in vitro anti-arthritic assays revealed that CC-AgNPs are better anti-gout agents than EFECC. This research suggested that biosynthesized silver nanoparticles from C. colocynthis fruit are an important target in the field of anti-gout drug discovery.

Whey powder: a potential anti-diarrheal agent through its biofilm formation.

Whey, the natural product resulting from coagulation of milk is reported to have diverse pharmaceutical credentials. In the present investigation the anti-diarrhoeal activity of the whey powder was investigated. The Whey powder which was prepared using rennet powder and lactic acid, was studied against Magnesium sulphate-induced Diarrhea in Swiss Albino mice. Castor oil-induced enteropooling studies and in vitro biofilm-forming potentials of the whey powder were also carried out, as this is believed to contribute to the anti-diarrhoeal activities of the preparation. Anti-diarrhoeal activity was more pronounced in mice which received 250 mg kg b.wt. of whey powder when compared to those which received 500 mg kg(-1) b.wt. The percentage inhibition of total number of feces in the 250 mg kg(-1) b.wt. drug-treated group was 56.14%,whereas the animals which received 500 mg kg(-1) b.wt. of whey powder showed 37.18% inhibition. The loperamide treated animal group showed 63.81% inhibition. In castor oil induced enteropooling, the percentage inhibition of intestinal content in the 250 mg kg(-1) b.wt. drug-treated group was 61.42% against atropine-treated animal group that showed 26.24% inhibition. The whey powder also exhibited strong biofilm forming capacity with increase in concentration. The anti-diarrhoeal activity of whey preparation established herein is believed to be owing to certain active principles present in it or due to biofilm-forming capacity, which inhibits the attachment of mediators of diarrhoea to mucosal walls of the GI tract or due to interaction of diarrhoea inducing chemicals with whey peptides, which needs further investigation.

Antidiabetic antihyperlipidemic and hepato-protective effect of Gluconorm-5: A polyherbal formulation in steptozotocin induced hyperglycemic rats.

BACKGROUND: The antidiabetic, antihyperlipidemic, and hepato-protective effect of Gluconorm-5, was studied in steptozotocin (STZ) induced hyperglycemic rats. MATERIALS AND METHODS: The hypoglycemic effect of single dose of Gluconorm-5 (150, 300 and 600 mg/kg body weight) made up of five plants namely Camellia sinensis, Punica granatum, Macrotyloma uniflorum, Foeniculum vulgare and Trigonella foenum-graecum was studied in normal, glucose loaded normal and diabetes-induced rats. The extent of antihyperlipidemic and liver-protective effect was studied by estimating the lipid profile, and the liver marker enzymes. Histopathological studies of the pancreatic tissue were also carried out with glibenclamide as standard antihyperglycemic agent. RESULTS: Fifteen days of oral feeding of the Gluconorm-5 (300 and 600 mg/kg) to diabetic rats resulted in a significant (P < 0.01) reduction of blood glucose, lipid profile, liver weight and marker enzymes as compared to those rats in whom STZ induced toxicity was untreated. The diabetic rats treated with the drug showed expanded islets as compared to the untreated diabetic rats, which showed the shrunken islets. The animals that received 300 mg/kg of Gluconorm-5 showed pronounced antidiabetic, antihyperlipidemic and hepato-protective effect in the present study, which was comparable with glibenclamide, a standard drug. CONCLUSION: Gluconorm-5 exerts potent antidiabetic antihyperlipidemic and hepato-protective effect, which can be used as adjuvant in the treatment of diabetes mellitus.

Antioxidant activity of combined ethanolic extract of Eclipta alba and Piper longum Linn.

The in-vitro free radical scavenging efficacy of the combined ethanolic Biherbal extract (BHE) from equal quantities of the leaves of Eclipta alba and seeds of Piper longum was investigated. This was compared with its individual preparation of ethanolic extract of Eclipta alba (EAE) and ethanolic extract of Piper longum (PLE). The 1, 1, diphenyl -2-picrylhydrazyl (DPPH), super oxide, nitric oxide, hydroxyl radical scavenging activity and reducing power from BHE, EAE, and PLE were investigated employing various established in vitro systems. Total phenolic and flavonoid content were also determined. The results revealed that BHE has notable activity in quenching of DPPH, super oxide, nitric oxide, and hydroxyl radicals when compared to its individual preparation of EAE and PLE. The BHE at 1000µg/ml showed maximum scavenging of DPPH (88.75%) super oxide (84.78%) nitric oxide (89.02%) and hydroxyl (82.82%) against the scavenging of EAE and PLE which showed DPPH (81.77%,83.54%) super oxide (79.88 ± 1.84, 80.88 ± 1.44%) nitric-oxide (76.14 ± 1.80, 77.2 ± 1.18%) and hydroxyl (79.86%, 74.64%) radicals respectively at the same concentration. A linear correlation between BHE and reducing power was also observed. The quantitative estimation of the extract revealed the considerable amount of phenols and flavonoids. The results of this study strongly indicate that the BHE has more potent antioxidant potential action than its individual preparation EAE or PLE.
