In silico, in vitro VEGFR-2 inhibition, and anticancer activity of a 3-(hydrazonomethyl)naphthalene-2-ol derivative

Eslam B. Elkaeed, Reda G. Yousef, Hazem Elkady, Ahmed B. M. Mehany, Bshra A. Alsfouk, Dalal Z. Husein, Ibrahim M. Ibrahim, Ahmed M. Metwaly & Ibrahim H. Eissa
In agreement with the general features of VEGFR-2 inhibitors, a new naphthalene analog (compound 7) has been designed and synthesized. The inhibitory potential of compound 7 was indicated by the proper binding and the perfect energy of −21.10 kcal/mol compared to sorafenib (−21.22) in the molecular docking studies. Next, six MD simulation studies over 100 ns (RMSD, RMSF, SASA, RoG, hydrogen bonding, and distance between the center of mass) confirmed the accurate interaction of compound...

Ahmed Hamdan Al-Jedai, James Lomas, Hajer Yousef Almudaiheem, Yazed Sulaiman H. Al-Ruthia, Shabab Alghamdi, Nancy Awad, Ahlam Alghamdi, Mohammad A. Alowairdhi, Hana Alabdulkarim, Majid Almadi, Reem F. Bunyan & Jessica Ochalek
Saudi Arabia’s Vision 2030 aims to reform health care across the Kingdom, with health technology assessment being adopted as one tool promising to improve the efficiency with which resources are used. An understanding of the opportunity costs of reimbursement decisions is key to fulfilling this promise and can be used to inform a cost-effectiveness threshold. This paper is the first to provide a range of estimates of this using existing evidence extrapolated to the context...

Anti-cancer and immunomodulatory evaluation of new nicotinamide derivatives as potential VEGFR-2 inhibitors and apoptosis inducers: in vitro and in silico studies

Reda G. Yousef, Alaa Elwan, Ibraheem M. M. Gobaara, Ahmed B. M. Mehany, Wagdy M. Eldehna, Souad A. El-Metwally, Bshra A. Alsfouk, Eslam B. Elkaeed, Ahmed M. Metwaly & Ibrahim H. Eissa
New nicotinamide derivatives 6, 7, 10, and 11 were designed and synthesised based on the essential features of the VEGFR-2 inhibitors. Compound 10 revealed the highest anti-proliferative activities with IC50 values of 15.4 and 9.8 µM against HCT-116 and HepG2, respectively compared to sorafenib (IC50 = 9.30 and 7.40 µM). Compound 7 owned promising cytotoxic activities with IC50 values of 15.7 and 15.5 µM against the same cell lines, respectively. Subsequently, the VEGFR-2 inhibitory activities...

Abstract Background Data available support that ninety percent of male infertility cases are due to low sperm counts. There is a scarcity of data on the medicinal effects of cannabis on fertility. This study evaluated testicular function and sperm quality modulation with cannabis in rats. Methodology Twenty-five male Wistar rats were randomly grouped into five: A, B, C, and D, each group have 5 rats. A (control): 0.2 ml 2% DMSO, B (vitamin C): 90...

Abstract Background Inhaled nitric oxide (iNO) is used as rescue therapy in patients with refractory hypoxemia due to severe COVID-19 acute respiratory distress syndrome (ARDS) despite the recommendation against the use of this treatment. To date, the effect of iNO on the clinical outcomes of critically ill COVID-19 patients with moderate-to-severe ARDS remains arguable. Therefore, this study aimed to evaluate the use of iNO in critically ill COVID-19 patients with moderate-to-severe ARDS. Methods This multicenter,...
