In the current research, a piperidine containing chalcone [(E)-1-(1-methoxy-9H-carbazol3-yl)-3-(4-(piperidin-1-yl)phenyl)prop-2-en-1-one] was rationally developed by incorporating the natural portion (murrayanine) in the A-ring and a synthetic component (1-(4-(piperidin-1-yl)phenyl)ethanone, a piperidine containing acetophenone) in the B-ring and screened against two bacterial species (Escherichia coli and Staphylococcus aureus) and two fungal species (Candida albicans and Aspergillus niger). The chalcone (1, 3-diphenyl-2E-propene-1-one) candidate expressed a better anti-bacterial activity than that of anti-fungal activity. The chalcone displayed the highest activity against E. coli followed by S. aureus, and lowest against C. albicans. Although, were found to have less activity and potency than that of the standard compounds (ciprofloxacin and fluconazole). The current study will open new avenues of research on hybrid heterocyclic chalcones and will motivate researchers to further developing highly active compounds based on benzylideneacetophenone scaffold.","PeriodicalId":92256,"journal":{"name":"Journal of pharmacy and pharmaceutics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74465995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research work was to evaluate the impact of the Trivedi Effect® on the physicochemical and thermal properties of ofloxacin using modern analytical techniques. The sample was divided into two parts. One part of ofloxacin was considered as the control sample (no biofield energy treatment was provided), whereas the second part was received the Biofield Treatment remotely by a famous Biofield Energy Healer, Alice Branton and was termed as the treated sample. The PXRD peak intensities and crystallite sizes were significantly altered ranging from 7.45% to 73.06% and -44.1% to 77.95%, respectively in the treated sample compared to the control sample. The particle size values were significantly altered at d10 (-19.47%), d50 (1.14%), d90 (-8.70%), and D (4, 3) (-10.20%); whereas, the specific surface area was significantly increased by 15.66% in the treated sample compared to the control sample. The latent heat of fusion and latent heat of decomposition of the treated ofloxacin were significantly increased by 16.24% and 88.03%, respectively compared with the control sample. The total weight loss was significantly decreased by 6.21 %; additionally, the residue amount was significantly increased by 47.16% in the treated ofloxacin compared with the control sample. Thus, the Trivedi Effect® might generate a new polymorphic form of ofloxacin which would be more soluble, bioavailable, and be thermally more stable compared with the untreated sample. The Biofield Treated ofloxacin would be more efficacious against urinary tract infections, infections of the urethra and cervix, infectious diarrhoea, pneumonia, cellulitis, chronic bronchitis, prostatitis, plague, etc.","PeriodicalId":92256,"journal":{"name":"Journal of pharmacy and pharmaceutics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80496222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Entecavir is a guanosine nucleoside analogue with selective activity against hepatitis B virus (HBV), which inhibits reverse transcription, Hepatitis B virus (HBV) is highly endemic in South Africa and across sub-Saharan Africa, where around 8% of people are chronically infected, and rates of HBV-related liver cancer are some of the highest in the world. Globally, viral hepatitis causes approximately 1.3 million deaths every year more than either malaria or tuberculosis with around 240 million people chronically infected with HBV1. The currently available anti-HBV drugs show potent antiviral activity in patients with chronic hepatitis B; however, the resistance and cross-resistance to the drugs is a major obstacle in long-term treatment. Many studies have been conducted to understand the molecular basis of drug resistance, and the mechanistic characterization and molecular modeling of anti-HBV drugs complexed with HBV RT have been reported. Although the three-dimensional X-ray structure of HBV polymerase is not available, its homology model has been reported using the X-ray structure of HIV RT as a template[1-13]. Even though the homology models may not be accurate due to the low sequence homology between the overall HIV and HBV polymerase, the sequence conservation between the RT domains of HIV and HBV polymerase enables molecular modeling of HBV RT[14]. In particular, the residues around the active site that are responsible for recognizing the template-primer or an incoming nucleoside triphosphate are highly conserved. Nucleoside analogue HBV polymerase inhibitors cause chain termination after incorporation into the growing chain in the active site of HBV polymerase and consequently inhibit viral reverse transcriptase. Thus, the HBV homology model structure based on the crystal structure of HIV polymerase serves as a useful guide for understanding the molecular basis of HBV resistance to drugs..

Current status available on: http://patentsearch.cipc.co.za/, which should have permitted lower-cost generic competitors to enter the market. However, South Africa granted BMS three additional patents on entecavir that only expire between 2022 and 2026. Two of these patents have lapsed meaning BMS has not paid the renewal fees, and they cannot be enforced while one patent covering a lower dosage form of entecavir remains in force.

The aim of the study was to determine the phytochemical constituents and antibacterial activity of Garcinia kola seed extracts against clinical isolates of Methicillin Resistant Staphylococcus Aureus (MRSA). Total of 107 Staphylococcus isolates from infected wound and urine and were collected from Abubakar Imam Urology Center in Kano State, Nigeria over a period of eight months (October 2015 to May 2016). A disc diffusion method was used for characterization of MRSA. The phytochemical screening of the plant materials was done using conventional laboratory method while the antibacterial activity of the plant extracts was determined using agar well diffusion method. The result of bacterial characterization showed that eight isolates found were to be Methicillin Resistant Staphylococcus aureus (MRSA). Phytochemical screening of the seeds, leaves and stem bark extracts indicated the presence of Alkaloid, Tannin, Saponin, and Cardiac glycoside, Flavonoid, Terpenoid, Phenols Anthraquinone and Steroid. However, reducing sugar is absent. The antibacterial activity of the plant showed that the plant part extracts demonstrated antimicrobial effect against the test isolates with higher activity in seeds compared to leaves and stem. Statistical analysis of the result revealed that the overall average zone of inhibition shown by the extracts is 11.68 mm with methanolic seeds extract exerting the highest antibacterial effects on the test isolates with average zone of inhibition of 12.78 mm, followed by methanolic leaf extract 12.37 mm then aqueous seed extract with zone of inhibition of 11.87 mm. Least zones of inhibition were recorded in aqueous leaf extract and methanolic stem back extract with zones of inhibition of 11.28 and 10.43 mm respectively. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of the extracts range from 12.5 – 100 mg/ml of the extracts. Findings from this work support the use of seed extracts from G. kola as medicinal plant.","PeriodicalId":92256,"journal":{"name":"Journal of pharmacy and pharmaceutics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87677634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, EVs have been used to deliver molecules across tight cellular junctions such as the blood brain barrier. This has led to an interest in using EVs as a novel method for drug delivery.
