Potential inhibitors interacting in Neuropilin-1 to develop an adjuvant drug against COVID-19, by molecular docking

The COVID-19 pandemic continues without specific treatment. In this study it is proposed compounds that can be developed as adjuvant / complementary drugs against COVID-19. Through a search for molecular docking, for the development of a new drug using pharmacological compounds targeting the b1 region in neuropilin-1 (NRP1), which is important for the interaction with the S1 region of the S-Protein of SARS-CoV-2, to slow down the infection process of this virus. A molecular docking was performed using almost 500,000 compounds targeted to interact in the region between amino acids (Thr316, Asp320, Ser346, Thr349, and Tyr353) in NRP1 to determine compounds able to hinder the interaction with the S1 region in the S-Protein. In this study, ten compounds are proposed as potential inhibitors between S1 region in the S-Protein of SARS-CoV-2 with the b1 region in NRP1, to develop a new adjuvant / complementary drug against COVID-19, and to hinder the interaction between SARS-CoV-2 and human cells, with a high probability to be safe in humans, validated by web servers for prediction of ADME and toxicity (PreADMET).
