Inhibitors of the RBD-ACE-2 Found among a Wide Range of Dyes by the Immunoassay Method

Angiotensin-converting enzyme 2 (ACE2), the functional receptor of SARS-CoV-2, plays a crucial role in the pathogenesis of COVID-19. ACE2 targeting holds the promise for preventing and inhibiting SARS-CoV-2 infection. In this work, we describe the development and use of a test system based on competitive ELISA for the primary screening of potential antiviral compounds. We studied the activity of the library of dyes of different groups. Several dyes (ortho-cresolphthalein, eosin (free acid), eosin (Na salt)) that inhibited the interaction of ACE2 with the spike proteins of SARS-CoV-2 have been identified among the candidates. A potential antiviral drug, methylene blue, did not show activity in our study. We believe that our results can help in the further search for inhibitors of interaction between the coronavirus spike protein and ACE2 receptor

Amino acid formulas in patients with food allergy

The article presents modern approaches to the use of balanced formulas for nutrition and diet correction in children with various forms of food allergies. The guidelines are based on all available up to date evidence on the efficacy, safety and utility of using such innovative medical technology as specialized amino acid formulas. This formula is the targeted medical intervention for food allergies and confirmed cow's milk protein allergy, and particularly for patients with reduced physical growth and development (growth rates included). The material is based on methodological guidelines on the amino acid formulas usage previously developed by specialist experts of the Union of pediatricians of Russia in 2020
