Design, Synthesis, Characterization and Preliminary Anticancer Study for Methotrexate Silibinin Conjugates
...Show More Authors

The spectrum of clinical efficacy of Methotrexate (MTX) is broad in that MTX is used in the treatment of certain cancers, severe psoriasis and rheumatoid arthritis.Various mechanisms by which cancer cells grown in tissue culture become resistant to anticancer drugs. The use of multiple  drugs with different mechanisms of entry into cells and different cellular targets allows for effective chemotherapy and high cure rates. In an efforts to develop effective strategies that increase the therapeutic potential of anticancer drugs with less systemic toxicity ,are being directed  towards the investigation of dietary supplements and other phytotherapeutic agents for their synergistic efficacy in combination with anticancer drugs. A promising approach to improve the cancer cell selectivity of methotrexate is the chemical transformation into reversible derivatives which convert the conjugate to the parent drug by virtue of enzyme within cancer tissue. The present study includes the synthesis of  two derivatives of methotrexate which are :-Schiff base methotrexate-silibinin conjugate ( compound 5), and Methotrexate-silibinin conjugate (compound 6).The synthesis  of the target compounds was  accomplished following multistep reaction procedures. The chemical reactions were followed up and purity of the products was checked by TLC. The structures of the final compounds and their intermediates were characterized and identified by their melting points, infrared spectroscopy, 1H-NMR and elemental microanalysis(C H N S).The anticancer activity of these compounds was investigated by HEP-2 cell line(Larynx carcinoma), which showed  that compounds 5 and 6 have the higher activity than methotrexate or silibinin alone.These are promising data for the discovery of new anticancer agents in future. These compounds may deliver the parent drug  selectively  into the cancer cells to be hydrolyzed by enzymes that are elevated in  tumor tissues compared with normal tissues .

Keywords: Methotrexate, Silibinin, Cancer treatment resistance, Folate receptor, Cancer cell targeting.

Identifying the selection criteria of design consultant for Iraqi construction projects
...Show More Authors
Abstract<p>The quality and cost of constructed buildings are heavily influenced by the performance of design/auditing consultants. Thus, selecting the right design consultant and design auditing consultants is of utmost importance and not an easy task for any construction client. so, the client should specify the efficiency criteria and assess the performance levels of the design and design auditing consultant firm. The study aims to identify the selection criteria of the design consultant in construction projects and also identify the selection criteria of the design auditing consultant for the construction projects by using the Delphi survey with applying the principal components analysis (PCA</p> ...

A Comprehensive Review for Integrating Petrophysical Properties, Rock Typing, and Geological Modeling for Enhanced Reservoir Characterization
...Show More Authors

Reservoir characterization is an important component of hydrocarbon exploration and production, which requires the integration of different disciplines for accurate subsurface modeling. This comprehensive research paper delves into the complex interplay of rock materials, rock formation techniques, and geological modeling techniques for improving reservoir quality. The research plays an important role dominated by petrophysical factors such as porosity, shale volume, water content, and permeability—as important indicators of reservoir properties, fluid behavior, and hydrocarbon potential. It examines various rock cataloging techniques, focusing on rock aggregation techniques and self-organizing maps (SOMs) to identify specific and

Impact of TYMS gene polymorphism on the outcome of methotrexate treatment in a sample of Iraqi rheumatoid arthritis patients – identification of novel single nucleotide polymorphism: Cross-sectional study
...Show More Authors

The current work aims to evaluate the association between genetic mutations in thymidylate synthetase (TYMS gene in exon1 and partial regions of promotor and intron 1 [877 bp, 657,220–658,096 bp]) and the therapeutic outcomes for rheumatoid arthritis (RA) Iraqi patients. An observational cross-sectional study involving 95 RA patients with established RA patients based on their methotrexate treatment responsiveness. Genetic sequencing of the TYMS gene was performed for all patients according to the instruction manuals of the sequencing company (Macrogen Inc. Geumchen, South Korea). Four polymorphisms were identified by sequencing 95 randomly selected patients in the noncoding region of TYMS

A new carbonyl complexes of triazole and oxadiazole were synthesized. These complexes were identified and their structural geometric were suggested by using FT-IR and UV-Vis spectra, conductivity measurements and other chemical and physical properties. The spectra data (FT-IR, UV, Vis.) with the substantial aid of group theoretical calculations gave so many evidences for the proposed geometries and the type of bonding of these compounds
