  • Classical and Variant Approaches to Synthesis of N-Mannich Bases of Phenyl
           Hydroxyl Ketones, Their Characterization, Urease Inhibition and
           Antioxidant Activities

    • Authors: Oloyede; G. K., Ali, M. S, Lateef M., Anyaele, G. C., Adeniyi E.M.
      Abstract: In continuation of our synthesis and investigation of bioactivities of Mannich bases, synthesized N - Mannich bases were evaluated for their urease inhibition and antioxidant properties. Characterization was achieved by Ultraviolet/visible (UV), Infrared (IR), Nuclear magnetic resonance (1HNMR) and Mass spectrophotometries. Elemental analysis, optical rotation (OR) and circular dichroism (CD) measurement also confirmed and provided information about the structure of these compounds. Synthesis of novel 2-hydroxy-1,2,3-triphenyl-3-(phenylamino) propan-1-one, 2-hydroxy-1,2-diphenyl-3-(phenylamino) propan-1-one, 2-hydroxy-3-(2-hydroxyethylamino)-1,2,3-triphenylpropan-1-one and  2-hydroxy-1,2,3-triphenyl-3-(p-tolylamino)propan-1-one are newly reported along with 3-(2-(3,4-dimethoxyphenyl)ethylideneamino)-3-(4-hydroxyphenyl)-1-(2,4,6-trimethoxy phenyl) propan-1-one prepared by a variant approach involving use of tertiary amine. Jack bean Urease was used for Urease inhibition assay while in vitro antioxidant screening of the compounds was carried out using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH).  IC50 values obtained showed that the compounds showed significant activities as urease inhibitors and antioxidants when compared with Thiourea, Ascorbic acid and Butylated hydroxyanisole (BHA) used as standards in the two assays. Kinetics of inhibition of H. pylori urease by 1-Phenylaminomethyl-naphthalen-2-ol (GK1) and 2-(3-Phenylaminopropionyloxy)-benzoic acid (GK5) indicated that enzyme activity decreased as concentration of test compound increased. The IC50 value of 14.5 ± 0.71 mM (GK1)  and 14.3± 0.32 (GK5) indicated better activity when compared to thiourea (21.6 ± 0.12) used as standard. Keywords: Benzoin; tertiary amine; urease; thiourea; antioxidant; butylated hydroxyanisole

           (ECZ) Senior Secondary School Chemistry-5070/3 Practical Examinations

    • Authors: Billy Siachibila, Asiana Banda
      Abstract: The purpose of this study was to determine the science process skills inherent in the Examination Council of Zambia (ECZ) pure chemistry practical examinations (5070/3) for a period of 10 years (2007-2016). The study adopted the Ex-post facto research design. The questions from  the ECZ  chemistry-5070/3 practical examination (5070/3) from 2007-2016  were analyzed for science process skills based on the 12 categories of science process skills adopted from the AAAS (1993), with an addition of one more integrated skill which is graphing. Data were analyzed descriptively by computing frequencies and percentages. The results from the study shows that the science process skills included in the practical examinations are; interpreting data, experimenting, inferring, observation, measurement and communicating only. Among the 13 science process skills focused, the most prominent were observing (28.94%), measuring (15.44%), communicating (28.64%), and interpreting data (11.10%). Comparing the two categories of science process skills, basic and integrated science process skills, the results show a high percentage of the basic science process skills at 80.51% as compared to integrated science process skills at 19.50%. This implies that ECZ included more basic science process skills as compared to integrated science process skills in its national examination for the period from 2007 to 2016. These results have implications to chemistry teaching and learning at high school level. Keywords: chemistry, chemistry education, science education, practical examinations, science process skills.

  • Irrigation Water Quality Assessment and Salinity Management Strategies in
           Bahawalpur Division, Pakistan

    • Authors: Muhammad Aamer, Aftab Ahmed Khan, Muhammad Arif Goheer
      Abstract: Economy of Pakistan is agricultural based and it mainly dependent on canal supplies. Due to rapid population growth, there has been a dramatic increase in the intensity of ground water exploitation leading to decline water table and deteriorate ground water quality. Tube well water is one of the most common resources to support the irrigation in situation of canal water scarcity. Considering the importance of tube well water, present study was conducted for the quality assessment of tube well water to provide guidelines to farmer and researches for better crop production by adopting water management strategies. Total 1400 water samples were collected from Bahawalpur division during the year 2017. These samples were analyzed and categorized according to suitability criteria of water quality evaluation. 38.64 percent water samples were found fit, 7.65 percent were marginally fit and 53.7 percent water samples were found unfit for irrigation purpose. Majority of water samples were found hazardous for irrigation purpose. There is need to analyze the existing water resources and recommending comprehensive conservation and management strategies in view of catering the planning requirements for the future. Keywords: Salinity, Sodicity, Ground water, Bahawalpur, Pakistan.

           Peroxidase System

    • Authors: Ebrahim Naif Ismail
      Abstract: The carcinogenic chemicals are divided into two group: The first group: it is effective in cancer and does not require pre-activation, such as alkaline agents. The second group: their number is larger than the first group and need to be activated before they become carcinogenic, such as aromatic amines. When entering the organism, the chemical compounds are subject to the effect of enzymes, especially oxidation enzymes such as oxygenases and Peroxidases. In the Peroxidase oxidation of aromatic amines are oxidized And the amino group is transformed into an imino group.

  • Determination of the Potential Role and Health benefit of the
           Concentration of Vitamin c in some Fruit Samples

    • Authors: Maimuna Buba, Amina A. maitama
      Abstract: As a result of the rapid increase in stroke, lack of immune system functioning well, wrinkles on skin and so many more, this experiment was carried out to show the importance and benefits of vitamin c in the human body. Vitamin c content in four different fruit samples was determined by qualitative analysis (iodometric titration). Results obtained show variation in vitamin c content in different fruit samples and the value ranges from 0.0290 to 0.0054 showing higher amount of vitamin c in orange fruits compared to the other fruits. Other scientist that carried out similar experiment with different methods have shown varying results: in some cases orange fruits/juices have higher vitamin c content; some experiments were carried out on ripe and unripe fruits to determine the concentration of vitamin c in them. However, this experiment shows higher amount of vitamin c content in orange, lemon, pineapple and mango respectively. Key words: Ascorbic acid, iodometric titration, lemon, mango, orange, pineapple.
