Hypertension has been recognized as one of the most frequent comorbidities and risk factors for the seriousness and adverse consequences in COVID-19 patients. 3,4-dihydropyrimidin-2(1H) ones have attracted researchers to be synthesized via Beginilli reaction and evaluate their antihypertensive activities as bioisosteres of nifedipine a well-known calcium channel blocker. In this study, we report synthesis of some bioisosteres of pyrimidines as novel CCBs with potential ACE2 inhibitory effect as antihypertensive agents with protective effect against COVID-19 infection by suppression of ACE2 binding to SARS-CoV-2 Spike RBD. All compounds were evaluated for their antihypertensive and calcium channel blocking activities using nifedipine as a reference standard. Furthermore, they were screened for their ACE2 inhibition potential in addition to their anti‐inflammatory effects on LPS-stimulated THP‐1 cells. Most of the tested compounds exhibited significant antihypertensive activity, where compounds 7a, 8a and 9a exhibited the highest activity compared to nifedipine. Moreover, compounds 4a,b, 5a,b, 7a,b, 8a,c and 9a showed promising ACE2:SARS-CoV-2 Spike RBD inhibitory effect. Finally, compounds 5a, 7b and 9a exerted a promising anti-inflammatory effect by inhibition of CRP and IL-6 production. Ultimately, compound 9a may be a promising antihypertensive candidate with anti-inflammatory and potential efficacy against COVID-19 via ACE2 receptor inhibition.

Abstract: The preparation of bis(p-sulfoanilino)triazine-functionalized silica-coated magnetite nanoparticles and their use as a novel magnetically separable nanocatalyst for the synthesis of various Biginelli adducts are presented. The materials were characterized by various microscopic and spectroscopic techniques such as scanning electron microscopy, vibrating sample magnetometer, X-ray powder diffraction, and FT-IR spectroscopy, etc. A series of 3,4-dihydropyrimidinones or thione products were conveniently prepared by this green protocol from the reactions of aromatic aldehydes with the 1,3-dicarbonyl compounds and urea or thiourea using the catalyst under solvent-free conditions. The present method is operationally simple and offers several advantages such as good to excellent yields, short reaction times, the absence of a solvent, and simple work-up. Moreover, the aforementioned nanocatalyst can be easily recovered from the reaction mixture with the assistance of an external magnetic field and reused several times without any loss of its catalytic activity.
