The extracellular alkaline phosphatase from halotolerant facultative alkaliphile Bacillus flexus FPB17 was purified through precipitation / dialysis / chromatography and resulted in 28 fold of purification. The molecular weight of this enzyme through SDS-PAGE gel is 63 ± 2 kDa. Optimum conditions for purified ALP activity were pH 9.0 and 35°C. The enzyme proved to be thermolabile and gets completely denatured at 60°C in 10 min. p-NPP was found to be a preferred substrate and Km (0.33 mM) and Vmax (0.2 mM mg-1) determined using p-NPP as a substrate. Inorganic phosphate proved to be a competitive inhibitor of ALP. Mg+2 and Ca+2 increased the ALP activity by 47% and 20% respectively whereas Sodium fluoride, Sodium arsenate and EDTA decreased the activity by 47%, 65% and 77% respectively. The superiority of dephosphorylation of λ phage DNA by this newly discovered alkaline phosphatase over that of calf intestinal alkaline phosphatase of M/s. HiMedia Laboratories, Mumbai opens up possibility of its future use in molecular biology as a replacement of alkaline phosphatases...

We planned to clarify the association between the Vitamin D supplementation and predisposition of metabolic syndrome including obesity, diabetes mellitus, hypertension and dyslipidemia in arthritic patient with pre diabetic condition and to assess prediabetes interfere in the disease progression. Retrospective observational study was conducted on 236 patients. Of these, Arthritis patients with no co-morbid condition and not supplemented with Vitamin D (47), Arthritis patients supplementing with Vitamin D (63), Arthritis patients with prediabetic condition (68), Arthritic prediabetic patients supplementing with Vitamin D (58) were recruited based on inclusion and exclusion criteria. All anthropometric parameters and clinical findings were recorded the predominance of women with RA was observed in this study and the body weight was increased substantially in entire study group irrespective of gender. A significant increase in metabolic parameters was observed in patients with arthritis who were off of Vitamin D supplementation (p<0.05). On the other hand no such significant increase was observed in vitamin D supplemented group (p>0.05. In the group of arthritic patients with prediabetes condition...

Heterocyclic compounds are well known for their different biological activities like anti-inflammatory, antibacterial, antifungal, anticancer, insecticidal, pecticidal, antibiotic, etc. the versatile applications of oxygen, nitrogen and sulphur containing heterocyclic compounds have made this area of extensive research. The present study deals with the synthesis of some new 3-(2′-hydroxy-3′-nitro-5′-methylphenyl)-5-(aryl/heteryl) pyrazoles synthesis from 1-(2′-hydroxy-3′-nitro-5′-methylphenyl) – 3 – aryl/heteryl – 2-propen-ones i.e. chalcone by reaction with hydrazine hydrate in ethanol and synthesized compounds screening for antimicrobial...

Diazonium salt of 2-(p-aminophenyl)-1,8-naphthyridine (I) was coupled with active methylene compounds to afford the hydrazono-1,8-napthyridinyl (III-V) and azo(VI) derivatives. Hydrazono ethyl acetoacetate (III) and ethyl cyanoacetate (IV) derivatives on treatment with hydrazine and substituted hydrazine’s were later reacted with hydroxylamine HCl in the presence of ethanol followed by cyclization to afford pyrazolinone (IIIa-e) & (IVa-e) and isoxazolinones (VII&IX). Hydrazono acetyl acetone (V) and azo dibenzoyl methane (VI) derivatives on treatment with hydrazine and substituted hydrazines, hydroxylamine HCl and with urea in the presence of ethanol followed by cylization resulted in the formation of pyrazoles (Va-e) & (VIa-e), isoxazole (IX&XI) and substituted pyrimidine-2-ones (X&XII). All the newly synthesized compounds were screened for their in-vitro antibacterial activity & antifungal activity by Agar cup-plate method and Serial dilution methods. In Agar cup plate method the Compounds IIId, IVd, VId showed Impressive antibacterial and antifungal activity. In Serial dilution method the compounds Vd & VId showed excellent antibacterial activity against B.Subtilis with an MIC of 7.8 µg/ml where as the compounds IVd, Vd...

Introduction: Non Steroidal Anti Inflammatory drugs are widely used drugs worldwide for various inflammatory conditions and acute as well as chronic pain conditions. In India large number of NSAIDs preparations are available in the market. Therefore choosing a NSAID becomes very difficult task for the prescribing physician. Objective: To evaluate the price variation of the different NSAIDs preparation available in the Indian market. Material And Methods: Cost of a particular drug in the same strength and dosage forms being manufactured by different companies was obtained from “Current Index of Medical Specialties” (CIMS) Jan-Apr, 2015 and “Indian Drug Review” (IDR) Issue 1,2015. Difference between the maximum and minimum cost of the same drug manufactured by different pharmaceutical companies was calculated and percentage cost variation was calculated. Spearman correlation analysis and regression coefficient was done to observe the correlation between no. of manufacturing companies and their percentage price variation with the help of IBM Statistical Package for Social Sciences (SPSS v.21). Result: NSAIDs combination were commonly found as Oral and Topical...
