Michela Maestrini, Marcelo Beltrão Molento, Simone Mancini, Francesco Saverio Robustelli della Cuna, Giovanni Furnari, Donatella Serio, Laura Cornara, Stefania Perrucci

Abstract: The anthelmintic properties and composition of an Italian traditional anthelmintic remedy based on a red algae mixture (RAE) was assessed using the egg hatch test (EHT). The ability of different dilutions \((1.0, 5.0, 50,\) or \(100%)\) of RAE was determined and compared with the positive and negative controls against gastrointestinal nematode (GIN) of donkeys. The experiment was performed in triplicate. Data were analysed using the ANOVA and Tukey test. In the mixture, Palisada tenerrima, Laurencia intricata and Laurencia spp. red algae were identified. The $100\%$ RAE was able to totally inhibit the egg hatch, showing an efficacy comparable \((P < 0.05)\) to that of the reference drug \((98.7%)\). An egg hatch reduction of \(89.5, 43.7\), and \(23.4%\) was observed at \(50, 5\) and \(1%\) dilutions, respectively. In conclusion, RAE was able to inhibit the egg hatch of GIN of donkeys in a concentration-dependent manner with a correlation coefficient \((R2)\) of $0.968$, corroborating with its anthelmintic effect.

OJC-Vol. 3 (2020), Issue 1, pp. 6 – 12 Open Access Full-Text PDF

Aisha Batool, Farah Kanwal, Shahzad Ahmad, Sumreen Asim, Murtaza Saleem

Abstract: In this research, we reported facile synthesis of efficient \(Ni_3Fe\) electrocatalyst nanostructures deposited on conducting carbon fibers surface by a simple chemical bath deposition method at moderate temperature. The composition, phase and electrocatalytic property of as-prepared binder-free electrocatalyst was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and electrochemical measurements. The as-synthesized \(Ni_3Fe@t-CF\) presented excellent performance and durability as water oxidation electrocatalyst in alkaline electrolyte owing to non-segregated deposition of \(Ni_3Fe\) nanostructures on conducting surface of carbon, high electrochemical surface area, and the fast absorption and desorption of water molecules during oxygen evolution reaction due to the \(3D\) architecture of conducting interlaced carbon fibers template.

OJC-Vol. 3 (2020), Issue 1, pp. 1 – 6 Open Access Full-Text PDF

Francesco Saverio Robustelli della Cuna, Ilaria Bruni, Morena L. Martínez, Marvin J. Núnez

Abstract: Couroupita guianensis Aubl. (Lecythidaceae) “Cannonball tree” is a tropical plant with ethnobotanical uses. The present study is focused on analyzing the essential oil composition of Couroupita guianensis (C. guianensi) fresh flowers collected in El Salvador. Steam distillation, coupled with GC/FID and GC/MS analysis were employed to characterize the chemical composition and in vitro antioxidant activity study were carried out using DPPH assay. Eugenol was identified to be the most abundant constituent and quantified as \(46.20\)% of the total volatiles. Other constituents were found to be \(2\)-phenylethanol \((34.82\)%), \((E)-(E)\)-farnesol \((5.53\)%), nerol \((3.95\)%), geraniol \((3.20\)%), benzyl alcohol \((1.77\)%). \(DPPH\) assay showed a dose-dependent antioxidant activity. The study demonstrated that C. guianensis essential oil from El Salvador is a rich source of eugenol, which may be responsible for its antioxidant properties. Based on these results, further studies on the antibacterial and antifungal activity of C. guianensis essential oil are of fundamental importance.

Design, synthesis of spiro quinazolinone compacted with chitosan through DFT approach for interference the antimicrobial activity

OJC-Vol. 2 (2019), Issue 2, pp. 33 – 42 Open Access Full-Text PDF

Eman Abdel-Nasser, Jehan A. Hafez, Radwa M. Badawy, Hadeer I. Mohamed, Sameh A. Rizk

Abstract: In this work, we present a newly three antimicrobial chitosan, 2-benzoxazinyl benzoic acid (BBA) and novel biopolymer of Chitosan-spiroquinazolinone (SQC) via coupling of chitosan with benzoxazinyl benzoic acid, for promoting the antimicrobial activity of inherent chitosan. Modification in the chemical structure of the synthesized product SQC was confirmed using FT-IR and UV analysis. The antimicrobial activities of Chitosan, and BBA compounds were expressively increased more than chitosan-spiroquinazolinone SQC. Minimum inhibitory concentration (MIC) of compound SQC was supposed at \(50\mu g/ml\) against tested microorganisms except for B.cereus and C.albicans. The highest concentration of Chitosan would prevent the growth of Gram-+ve upto 99%. However, compound BBA recorded the maximum inhibition percentage versus Gram-+ve approximately 82%. The findings emphasized that the developed Chitosan-Spiroquinazolinone SQC may be blocker for antimicrobial activity to pure chitosan and BBA i.e, stop reaction if possible for actions of antimicrobial treatments.

Abstract: Glaucoma is a second leading cause of blindness worldwide and stands on fourth position among the cause of blindness. Two main types of Glaucoma, primary congenital Glaucoma (PCG) and primary open angle Glaucoma (POAG). Primary open angle Glaucoma is further classified in to primary juvenile open angle Glaucoma JOAG (age of onset 3-35 years) and adult onset open angle Glaucoma (after the age of 35 years). Myocilin (MYOC) gene plays a major role in the development of adult primary open angle Glaucoma (POAG). Mutations in Myocilin (MYOC) gene are well documented to cause Adult Primary Open Angle Glaucoma (POAG). Currently, very few data is available on the contribution of Myocilin (MYOC) gene in POAG in Pakistani population. In present study, fifty seven sporadic cases of autosomal recessive samples of Primary Open Angle Glaucoma (POAG) were collected from different hospitals of Lahore, Pakistan. Sequencing was performed to check the contribution of (MYOC) gene and to identify the common mutations present in Pakistani population. Sequencing results revealed previously reported one heterozygous synonymous single nucleotide polymorphism SNP and a variant in intronic exonic boundary of exon 2. Findings of this study revealed that contribution of (MYOC) gene is high. Therefore, there is need to enroll more patients and families to identify the pathogenic mutations in (MYOC) gene to report actual frequency of this gene and its mutations in our population. Mutations identified in this gene may be helpful at clinical level to diagnose the disease at early stages.

Investigation of nanostructured iron oxides as anodic material for water splitting

OJC-Vol. 2 (2019), Issue 2, pp. 15 – 21 Open Access Full-Text PDF

Masood Rauf Khan, Zahid Sarfraz, Hafiz Sami ur Rehman

Abstract: We explore the possibility of using an iron-based anodic material (\(\alpha\)-hematite) synthesized with a hierarchical 3D urchin-like morphology, as an OER catalyst. The electrodes are prepared by pulsed laser deposition followed by thermal annealing leading to the hierarchical 3D urchin-like morphology. The effect of the deposition parameter on the catalyst phase and morphology are investigated by microRaman spectroscopy and scanning electron microscopy, while the electrode metrics are determined by voltammetric methods and Tafel analysis. We observe that the material is highly electroactive towards the OER, with performance in-line with that of noble-metal based state-of-the-art catalysts.

ASpin-NMR data reporting tool

OJC-Vol. 2 (2019), Issue 2, pp. 9 – 14 Open Access Full-Text PDF

Francesco Sinopoli, Alessandro Sinopoli

Abstract: Nuclear Magnetic Resonance spectroscopy, commonly referred as NMR spectroscopy, is a widely used technique for determining the structure of organic compounds and metallorganic complexes. The NMR characterization process can be done automatically by specific tools integrated into the main NMR dedicated software, however it is commonly subjected to user’s interpretation therefore it still remains a manual process. In relationship with the number of signals to interpret and the complexity of the spectrum, the user usually spends between ten minutes and one hour to manually generate an NMR report, which can be clearly affected by typos or format mismatches. Here we report an Excel sheet-based NMR data reporting tool which, thanks to ad hoc macros, generates as output a formatted NMR report, ready to be directly pasted into any manuscript. ASpin tool leaves to the users the full possibility to interpret the spectrum in this way they can gain more experience in the interpretation process, without giving up the time saving.

OJC-Vol. 2 (2019), Issue 2, pp. 1 – 8 Open Access Full-Text PDF

Suresh Aluvihara, Jagath K. Premachandra

Abstract: Metals play predominant prefaces regarding most of industrial components such as the crude oil refining industry although corrosion performed some banes. In the current research it was expected to investigate to compare the effect of corrosive properties of two different crude oils on the rates of corrosion in seven different types of ferrous metals. The contents of sulfur, mercaptans, organic acids, salt in both crude oils and chemical compositions of ferrous metals were determined by standard methods and instruments. A batch of similar sized metal coupons was prepared and immersed in both crude oils separately. The corrosion rate of each metal coupon was determined by the weight loss method in order to after 15, 30 and 45 days while observing the corroded metal surfaces by the optical microscope. The decayed concentrations of copper and ferrous in each crude oil sample were tested and the both initial and final hardness of each metal coupon were tested. According to the results there were observed lower corrosion rates from stainless steels, relatively higher impact from salts on the corrosion, formation corrosion compounds, corrosion cracks, pitting corrosion on metal surfaces and there were observed a slight reduction of hardness in each metal coupon eventually.

Abstract: Matrix metalloproteinases-2 and -9 (MMP-2/-9) are key tissue remodeling enzymes that have multiple overlapping activities critical for wound healing and tumor progression. In search of new anti-tumor agents, indole-oxadiazole containing butanamides (1-5) were evaluated with B16F10 mouse melanoma cells in this study. The results showed that compounds 1, 2 and 3 inhibited the cell proliferation in a considerable manner at concentrations ranging from 0-44M. The possible migration inhibitory effects of these melanoma cells were further evaluated through gelatinolytic activity of MMP-2 and MMP-9 secreted from B16F10 cells and it was inferred that compounds 1, 2 and 3 affected the expression and activity of these enzymes in a dose dependent manner while compound 1 can be regarded as promising anti-tumor agent.

Abstract: Sulfonamides are considered to be biologically active and an important class of pharmaceutical compounds. These constitute an important class of antimicrobials, antidiabetics, anticancer and diuretics. These were the first chemotherapeutic drugs introduced to the world but their rapidly developed resistance decreased their use. In the present work, N-(2/4-substitutedphenyl)-4-(substituted)benzenesulfonamide (3a-d) and N-(tetrahydrofuran-2-ylmethyl)-4-methylbenzenesulfonamide 3e were synthesized by the reaction of substituted aniline (1a-c) and tetrahydrofuran-2-ylmethanamine (1d) with substituted benzenesulfonyl chloride (2a-d) using 10% aqueous \(Na_{2}CO_{3}\) solution as a reaction medium. In the second step, the synthesized molecules 3a-e were allowed to react different alkyl/aralkyl halides (4a-j) to synthesize the target N-substituted compounds, 5a-z,aa,bb, using lithium hydride as an activator and N,N-dimethylformamide (DMF) as a reaction medium. All the synthesized compounds were characterized by using spectral techniques such as \(^{1}\)H-NMR, IR and EI-MS; and further examined for their anti-bacterial activities.

OJC-Vol. 1 (2018), Issue 1, pp. 01–11 | Open Access Full-Text PDF

Sajid Mahmood, Muhammad Arshad, Zaheer Ahmed

Abstract:The objective of the present work was to develop and validate of an analytical method for the quantitative determination of Fexo. HCL and Pseudo. HCL in a combine tablet dosage form by \(UV-V\) is spectrophotometry and TLC. The main problem was to separate the two active ingredient from a single bilayered tablet because both the A.P.I’s were soluble in the same solvents. As media selection, distilled water and ethanol \((1:1)\) were used for Pseudo. HCl and methanol for Fexo. HCl, in which both the drugs were soluble and stable for a sufficient time. Both drugs were measured at \(220\)nm and \(247\)nm, where they showed maximum absorbance. Beer Lambert’s law was obeyed at concentration range \(4-14\) ppm and \(5-30\) ppm for Fexo. HCL and Pseudo HCL respectively. Fexo. HCl \((Y=0.0643x+0.9370)\) was measured with correlation coefficient \(r =0.9574\) and Pseudo. HCl \((Y=0.0843x+0.0219)\) with correlation coefficient \(r =0.9992\). The results of analysis have been validated statistically and recovery studies were carried out as \(99.29\%\pm 0.943\) and \(99.29\%\pm 0.941\) which were close to the assay value \(100.1\% \& 100.6 \%\). Precision of the method was measured which showed results for SD \((99.57 \% \;\;\& \;\;99. 51% )\) and \(\%\) RSD \((99.53 \%\;\; \&\;\; 99.54)\). The proposed method may be suitably applied for the analysis of Fexo. HCL and Pseudo.HCL in tablet pharmaceutical formulation for routine analysis.
