Topological Study of Some Covid-19 Drugs by Using Temperature Indices

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) was identified in December (2019) as the cause of an outbreak of a respiratory sickness and has infected more than 190 million people all over the world. Numerous vaccines have been tested for corona virus (Covid-19) therapy such as Hydoxychloroquine, Ribavirin, sofosbuvir, tenofuvir and remdisivir. Hydroxychloroquine (HCQ), which is used in the treatment of malaria or treat infection, has recently been demonstrated for use in COVID-19 as an emergency therapy. The chemical substance HCQ is manufactured by rearranging the molecular structure of Ethylene oxide produced by human products, such as waxy maize starch. In medical science chemical properties, physical properties, pharmaceutical properties and biological properties of medicines are essential for designing of the drugs. These properties can be identified by topological indices. In this paper, we compute the temperature based topological indices of hydroxychoroquine HCQ-HES, and the discoveries will be beneficial in the development of novel drugs and vaccines in order to avoid and operation of corona virus (COVID-19).

On entropy measures for molecular structure of remdesivir system and their applications

In medical sciences, the molecular structure is discussed under the consideration of the topological index, and related biological, pharmaceutical, medical and chemical properties of various drugs are examined by computing topological indices. Many scientific experiments are ongoing for the medication of COVID‐19 by using redeliver. In this paper, our objective is to calculate the degree‐based temperature indices and their respective temperature entropies for the molecular graph of remdesivir R. In this study, we derived some degree‐based temperature descriptors. Also, we computed temperature entropies of molecular structure by constructing the relation of degree‐based temperature descriptors with the help of specific information functions. Moreover, we analyzed and provided a graphical comparison of the calculated outcomes. These computed results maybe lead to the discovery of more effective drugs and modified vaccines for the overcome with COVID‐19.
