The aim of this research work was to evaluate the impact of the Trivedi Effect®-Consciousness Energy Healing Treatment on the physicochemical properties of ofloxacin using modern analytical techniques. The sample was divided into control and Biofield Energy Treated parts. The control sample did not receive the Biofield Energy Treatment; whereas, the treated part received the Biofield Treatment remotely by a famous Biofield Energy Healer, Gopal Nayak. The PXRD peak intensities and crys-tallite sizes were significantly altered ranging from -39.33% to 127.93% and -68.28% to 21%, respectively; however, the average crystallite size of the treated ofloxacin (236.59nm) was decreased by 19.48% compared with the control sample (293.83nm). The particle size values were signifi-cantly decreased at d10 (10.67%), d50 (25%), d90 (24.4%), and D (4,3) (25.12%); thus, the specific surface area was significantly increased by 9.8% in the treated sample compared to the control sample. The latent heat of fusion and the latent heat of decomposition of the treated sample were significantly increased by 11.71% and 123.52%, respectively compared to the control sample. The total weight loss was significantly decreased by 10.59%; however, the residue amount was significantly increased by 63.29% in the treated ofloxacin compared with the control sample. The Trivedi Effect®-Consciousness Energy Healing Treatment generated a new polymorphic form of ofloxacin which may be more soluble, bioavail-able, and be thermally more stable compared to the untreated sample. The treated ofloxacin would be more efficacious against cellulitis, prosta-titis, chronic bronchitis, urinary tract infections, infections of the urethra and cervix, pneumonia, infectious diarrhoea, plague, etc.","PeriodicalId":19547,"journal":{"name":"Organic & Medicinal Chemistry International Journal","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79309812","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 striking feature of this reaction is the formation of hydrazone in situ which in turn undergoes the cyclization with mercepto acetic acid, leading to the formation of new thiazolidinones. Thus, the thiazolidinone ring closes at carbonyl carbon, by the attack of sulfur of mercaptoacetic acid moiety, preferentially from the front (β, axial) so that the nitrogen has an equatorial orientation (α, equatorial) to avoid steric repulsion, giving minimum steric hindrance. The new compounds were characterized by spectral (IR, 1 H NMR, 13 C NMR, MS) and analytical methods.
