Design, synthesis and mechanistic study of novel diarylpyrazole derivatives as anti-inflammatory agents with reduced cardiovascular side effects.

Bioorganic chemistry

Amin NH, Hamed MIA, Abdel-Fattah MM, Abusabaa AHA, El-Saadi MT.
PMID: 34619468
Bioorg Chem. 2021 Nov;116:105394. doi: 10.1016/j.bioorg.2021.105394. Epub 2021 Sep 30.

Novel diarylpyrazole (5a-d, 6a-e, 12, 13, 14, 15a-c and 11a-g) derivatives were designed, synthesized and evaluated for their dual COX-2/sEH inhibitory activities via recombinant enzyme assays to explore their anti-inflammatory activities and cardiovascular safety profiles. Comprehensively, the structures of...

Targeting inflammation and redox aberrations by perindopril attenuates methotrexate-induced intestinal injury in rats: Role of TLR4/NF-κB and c-Fos/c-Jun pro-inflammatory pathways and PPAR-γ/SIRT1 cytoprotective signals.

AIMS: The use of methotrexate (MTX), a classical immunosuppressant and anti-cancer agent, is associated with multiple organ toxicities, including the intestinal injury. Components of the renin-angiotensin system are expressed in the intestinal epithelium and mucosal immune cells where they...

Diffusiophoretic Focusing of Suspended Colloids.

Physical review letters

Shi N, Nery-Azevedo R, Abdel-Fattah AI, Squires TM.
PMID: 28036214
Phys Rev Lett. 2016 Dec 16;117(25):258001. doi: 10.1103/PhysRevLett.117.258001. Epub 2016 Dec 15.

Using a microfluidic system to impose and maintain controlled, steady-state multicomponent pH and electrolyte gradients, we present systems where the diffusiophoretic migration of suspended colloids leads them to focus at a particular position, even in steady-state gradients. We show...

Efficient conversion of sulfones into beta-keto sulfones by N-acylbenzotriazoles.

The Journal of organic chemistry

Katritzky AR, Abdel-Fattah AA, Wang M.
PMID: 12585885
J Org Chem. 2003 Feb 21;68(4):1443-6. doi: 10.1021/jo026636l.

Acyclic sulfones 4a-f and alicyclic sulfone 7 react with readily available N-acylbenzotriazoles 3a-g (derived from aliphatic, aromatic, and heteroaromatic carboxylic acids) to provide the corresponding beta-keto sulfones 5a-n and 8a-c, respectively, in good to excellent yields.

Rasmussen's pseudoaneurysm- case report.

Respiratory medicine case reports

Respir Med Case Rep. 2018 Aug 25;25:150-153. doi: 10.1016/j.rmcr.2018.08.017. eCollection 2018.

BACKGROUND: Pulmonary aneurysms and pseudoaneurysms have various etiologies; however, the term Rasmussen's pseudoaneurysm refers specifically to a focal dilatation of a branch of the pulmonary artery into adjacent tuberculous cavity. The incidence of such tuberculosis related pulmonary vascular complication...

Research (Wash D C). 2019 Feb 04;2019:9854593. doi: 10.34133/2019/9854593. eCollection 2019.

A contactless label-free method using a diamagnetophoretic ink to rapidly print three-dimensional (3D) scaffold-free multicellular structures is described. The inks consist of MCF-7 cells that are suspended in a culture medium to which a paramagnetic salt, diethylenetriaminepentaacetic acid gadolinium...

Molecular Assembly of Surfactant Mixtures in Oil-Swollen Micelles: Implications for High Salinity Colloidal Stability.

The journal of physical chemistry. B

Chen H, Gizzatov A, Abdel-Fattah AI.

J Phys Chem B. 2020 Jan 23;124(3):568-576. doi: 10.1021/acs.jpcb.9b09929. Epub 2020 Jan 10.

Alkylbenzene sulfonates are one of the most important synthetic surfactant families, considering their wide applicability, cost-effectiveness, and overall consumption levels. Nevertheless, their low salt tolerance (especially divalent ion contents) prevented their wider applications such as enhanced oil recovery in...
