2-(3-Bromophenyl)-8-fluoroquinazoline-4-carboxylic Acid as a Novel and Selective Aurora A Kinase Inhibitory Lead with Apoptosis Properties: Design, Synthesis, In Vitro and In Silico Biological Evaluation

New quinazoline derivatives were designed based on the structural modification of the reported inhibitors to enhance their selectivity toward Aurora A. The synthesized compounds were tested over Aurora A, and a cytotoxicity assay was performed over NCI cell lines to select the best candidate for further evaluation. Compound 6e (2-(3-bromophenyl)-8-fluoroquinazoline-4-carboxylic acid) was the most potent compound among the tested derivatives. A Kinase panel assay was conducted for compound 6e over 14 kinases to evaluate its selectivity profile. Further cell cycle and apoptosis analysis were evaluated for compound 6e over the MCF-7 cell line at its IC50 of 168.78 µM. It arrested the cell cycle at the G1 phase and induced apoptosis. Molecular docking was performed to explore the possible binding mode of compound 6e into the active site. It showed significant binding into the main pocket in addition to potential binding interactions with the key amino acid residues. Accordingly, compound 6e can be considered a potential lead for further structural and molecular optimization of the quinazoline-based carboxylic acid scaffold for Aurora A kinase selective inhibition with apoptosis properties

Genetic Association Between Polycystic Ovary Syndrome and the rs662799 and rs894160 Metabolic Variants in the Western Saudi Population: A Case-Control Study

Background: Polycystic ovary syndrome (PCOS) is a common endocrinological condition affecting women of reproductive age, associated with insulin resistance and obesity. PCOS pathogenesis is complex and multifactorial, involving genetic and environmental factors. Objectives: This study aimed to determine and compare genotype and allele frequencies of single nucleotide polymorphisms (SNPs) in the apolipoprotein A5 ( APOA5 ; rs662799) and perilipin 1 ( PLIN1 ; rs894160, rs1052700 and rs6496589) genes in Western Saudi women to investigate their association with PCOS and its clinical characteristics. Design and methods: This was a case-control study conducted on women with ( n  = 104) and without ( n  = 87) PCOS. The SNPs were genotyped using TaqMan genotyping assays. Results: Significant and direct associations were detected between PCOS susceptibility and APOA5 SNP rs662799 and PLIN1 SNP rs894160 ( P  < .001). For APOA5 SNP rs662799, women with the A allele were more likely to have PCOS (relative risk [RR] = 1.348, odds ratio [OR] = 2.313, P  < .001) and hypertriglyceridaemia (OR = 17.0, P  = .5) than women with the G allele. For PLIN1 SNP rs894160, women with the T allele were more likely to have PCOS than women with the C allele (RR = 8.043, OR = 7.427, P  < .001). For PLIN1 SNP rs1052700, women with the TT genotype were more likely to have hyperandrogenism (OR = 29.75, P  = .02) and an irregular period (OR = 0.07, P  = .040) than women with the AT genotype. Conclusion: We identified novel alleles and genotypes contributing to the genetic risk of PCOS in the Western Saudi population

Avian influenza virus surveillance in migratory birds in Egypt revealed a novel reassortant H6N2 subtype

Background Avian influenza viruses (AIVs) have been identified from more than 100 different species of wild birds around the globe. Wild migratory birds can act as potential spreaders for AIVs to domestic birds between different countries. Egypt is situated on important migratory flyways for wild birds between different continents. While much is known about circulation of zoonotic potential H5N1 and H9N2 AIVs in domestic poultry in Egypt, little is known about the pivotal role of migratory birds in the maintenance and transmission of the viruses in Egypt. Methods Targeted AIV surveillance has been conducted in 2017 in different wetlands areas in Northern and Eastern Egypt. Results AIV of subtype H5 was detected in two bird species. In addition, a novel reassortant strain of the H6N2 subtype was identified which reveals the continuous risk of new influenza virus(es) introduction into Egypt. This novel virus possesses a reassortant pattern originating from different AIV gene pools. Conclusions Intervention control strategies should be performed to minimize the possible contact of domestic birds with wild birds to lower the risk of virus transmission at this interface. In addition, constant monitoring of AIVs in migratory birds is essential in the early detection of influenza virus introduction into Egypt
