Aim: COVID-19 is currently the biggest threat to mankind. Recently, ivermectin (a US FDA-approved antiparasitic drug) has been explored as an anti-SARS-CoV-2 agent. Herein, we have studied the possible mechanism of action of ivermectin using in silico approaches. Materials & methods: Interaction of ivermectin against the key proteins involved in SARS-CoV-2 pathogenesis were investigated through molecular docking and molecular dynamic simulation. Results: Ivermectin was found as a blocker of viral replicase, protease and human TMPRSS2, which could be the biophysical basis behind its antiviral efficiency. The antiviral action and ADMET profile of ivermectin was on par with the currently used anticorona drugs such as hydroxychloroquine and remdesivir. Conclusion: Our study enlightens the candidature of ivermectin as an effective drug for treating COVID-19.
has relatively much higher water solubility and lipophilicity, further, having lesser skin permeation on the other hand (Supplementary Table 2 ). The three drugs included in the study are FDA-approved drugs and used for treating various parasitic (ivermectin and hydroxychloroquine) and viral (remdesivir) infections of human. However, to present the suitability of ivermectin for treating COVID-19, we have compared the pharmacological properties of ivermectin with the other two drugs. Taken together, our data on the interaction between ivermectin and viral proteins indicated that ivermectin majorly acts by interfering with the viral entry through inhibiting the function of spike protein and protease. These studies also indicate that ivermectin may also target human ACE2 and TMPRSS2 for exerting its inhibitory action over SARS-CoV-2. However, all these in silico studies require subsequent experimental validation, which could enable Ivermectin as a drug of reliance to be used for counteracting the viral growth.
Conclusion Developing an effective therapeutic against COVID-19 is currently the utmost interest to the scientific communities. The present study depicts comparative binding efficacy of a promising FDA-approved drug, ivermectin, against major pathogenic proteins of SARS-CoV-2 and their human counterparts involved in host-pathogen interaction. Herein, our in silico data have indicated that ivermectin efficiently utilizes viral spike protein, main protease, replicase and..
