“…Due to their substantial applications across industries, including biological, agricultural, medicinal and pharmacological fields, chemists have drawn their attention to various heterocyclic scaffolds, such as piperazines (Halimehjani et al, 2022), benzoxazole, benzothiazole (Zou et al, 2023), heterocyclic sulfonamides (Apiraksattayakul et al, 2022), benzofurans (Farhat et al, 2022), benzimidazoles (Nardi et al, 2023), thiadiazoles (Janowska et al, 2020), pyarzoles (Nazeer et al, 2023), lamivudines (Henriquez-Camacho et al, 2023), ciprofloxacin-based acetanilides (Zhang et al, 2018), triazoles (Irfan et al, 2024), quinoxalines (Montana et al, 2019), and oxadiazoles (Kerru et al, 2020;Irfan et al, 2022;Irfan et al, 2023). Notably, theophylline (Shahzadi et al, 2020;Shahzadi et al, 2022a), a naturally occurring methylxanthine, has found frequent therapeutic use in treating conditions such as asthma, respiratory deficits in premature infants, and chronic pulmonary obstructive disease (COPD).…”
