4. Synthesis of 1,2,3-Triazole Derivatives of 4,4'-Dihydroxybenzophenone and Evaluation of Their Elastase Inhibitory Activity
The present investigation describes the synthesis of a series of novel triazole derivatives from 4,4'-dihydroxybenzophenone along with their elastase inhibitory activity. The 1,2,3-triazoles were obtained via the copper(I)-catalyzed azide-alkyne cycloaddition reaction (CuAAC), also known as click reaction, between bis(4-(prop-2-yn-1-yloxy))benzophenone and s

5. Pyrazolyl-Tetrazoles and Imidazolyl-Pyrazoles as Potential Anticoagulants and their Integrated Multiplex Analysis Virtual Screening
This article reports a novel virtual screening algorithm seeking the rational identification of novel lead anticoagulants. Seven 5-(3-methyl-1-aryl-1H-pyrazol-4-yl)-1H-tetrazoles and seven novel 1-aryl-4-(4,5-dihydro-1H-imidazol-2-yl)-3-methyl-1H-pyrazoles were obtained in three steps starting from arylhydrazine hydrochlorides as raw materials in good yields

7. Screening and Binding Analysis of Flavonoids with Alpha-Amylase Inhibitory Activity from Lotus Leaf
Lotus leaf is gaining growing popularity due to its various benefits and widely usage. In this paper, ten flavonoids in lotus leaf extract were analyzed by high performance liquid chromatography (HPLC). Centrifugal ultrafiltration combined liquid chromatography was used to screen alpha-amylase inhibitors from ten flavonoids mixture and the binding degrees ra

8. Synthesis, Inhibition of Mycobacterium tuberculosis Enoyl-acyl Carrier Protein Reductase and Antimycobacterial Activity of Novel Pentacyanoferrate(II)-isonicotinoylhydrazones
Tuberculosis remains among the top causes of death triggered by a single pathogen. Herein, a greener synthetic approach for isonicotinoylhydrazones is described using ultrasound energy. These compounds were used as starting materials for synthesizing pentacyanoferrate(II)-isonicotinoylhydrazones, which inhibited the reaction catalyzed by Mycobacterium tuberc

9. BIODEGRADATION OF PHENOL BY FREE AND IMMOBILIZED CELLS OF A NOVEL Pseudomonas sp. NBM11
Abstract In the present study, a pure culture of bacterium (Pseudomonas sp. Strain NBM11) was isolated from the soil sample from a site contaminated with medical wastes and wastewater. The isolated strain can degrade up to 1000 mg/L of phenol completely. It was observed that temperature, pH and initial concentration of phenol play key roles in determining th

10. Preparation of Two Maleic Acid Sulfonamide Salts and Their Copper(II) Complexes and Antiglaucoma Activity Studies
Two novel proton transfer compounds (HAP)+(SAMAL)- and (HBI)+(SAMAL)-.H2O were obtained from (E)-4-oxo-4-(4-sulfamoylphenylamino)but-2-enoic acid (HSAMAL) and 2-aminopyridine (AP) or 1H-benzimidazole (BI), respectively. Copper(II) complexes of salts and of HSAMAL have also been prepared. They have been characterized by elemental, spectral, thermal analyses,

11. Effects of hydrolysis and digestion in vitro on the activity of bovine plasma hydrolysates as inhibitors of the angiotensin I converting enzyme
The angiotensin I-converting enzyme (ACE) inhibiting activity of bovine plasma hydrolyzates obtained by Alcalase 2.4 L at different degrees of hydrolysis (DH) was evaluated. For the evaluation of ACE inhibition (ACEI), Hippuryl-His-Leu was used as substrate and the amount of hippuric acid liberated by non-inhibiting ACE was determined by spectrophotometry at
