Under clinical trials, some of the repurposed antiviral drugs have been applied to COVID\u201019 patients and reported the efficacy of the drugs with the diverse inferences. Molecular topology has been developed in recent years as an influential approach for drug design and discovery in which molecules that are structurally related show similar pharmacological properties. It permits a purely mathematical description of the molecular structure so that in the development of identification of new drugs can be found through adequate topological indices. In this paper, we study the structural properties of the several antiviral drugs such as chloroquine, hydroxychloroquine, lopinavir, ritonavir, remdesivir, theaflavin, nafamostat, camostat, umifenovir and bevacizumab by considering the distance and bond measures of chemical compounds. Our quantitative values of the topological indices are extremely useful in the recent development of designing new drugs for COVID\u201019.<\/jats:p>","DOI":"10.1002\/qua.26617","type":"journal-article","created":{"date-parts":[[2021,2,21]],"date-time":"2021-02-21T04:14:17Z","timestamp":1613880857000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":65,"title":["Distance based and bond additive topological indices of certain repurposed antiviral drug compounds tested for treating <scp>COVID<\/scp>\u201019"],"prefix":"10.1002","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9620-7692","authenticated-orcid":false,"given":"Jia\u2010Bao","family":"Liu","sequence":"first","affiliation":[{"name":"School of Mathematics and Physics Anhui Jianzhu University  Hefei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4457-1046","authenticated-orcid":false,"given":"Micheal","family":"Arockiaraj","sequence":"additional","affiliation":[{"name":"Department of Mathematics Loyola College  Chennai Tamil Nadu India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8557-1643","authenticated-orcid":false,"given":"M.","family":"Arulperumjothi","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Loyola College University of Madras  Chennai Tamil Nadu India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1922-910X","authenticated-orcid":false,"given":"Savari","family":"Prabhu","sequence":"additional","affiliation":[{"name":"Department of Mathematics Sri Venkateswara College of Engineering  Sriperumbudur Tamil Nadu India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,2,20]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/ci020054n"},{"key":"e_1_2_8_3_1","volume-title":"Topological Indices and Related Descriptors in QSAR and QSPR","author":"Devillers J.","year":"1999"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsps.2017.04.027"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsps.2017.04.021"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/10406638.2020.1770306"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.2174\/1385272819666141216232659"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(20)30183-5"},{"key":"e_1_2_8_9_1","author":"Carvalho T.","year":"2020","journal-title":"Nat.
