Introduction: Corrosion is a fundamental process that significantly affects both economic and structural safety, particularly in metals. Among the various methods for corrosion protection, the use of inhibitors is one of the most practical approaches, especially in acidic environments [1]. Most commonly used acid inhibitors are organic compounds containing π-bonds …
Introduction: Varenicline (VRC, Figure 1), chemically known as 7,8,9,10-tetrahydro-6,10-methano-6H-azepino[4,5-g]quinoxaline (2R,3R), is a novel centrally acting agent that functions as a highly selective partial agonist of the nicotinic acetylcholine receptor. VRC exhibits both agonistic and antagonistic properties, providing the therapeutic advantage of alleviating nicotine withdrawal symptoms and cigarette cravings during abstinence, …
Introduction: Paddy is the largest food crop globally, producing not only rice but also significant amounts of waste known as rice husk (RH). RH is generated as a byproduct during rice processing, with an estimated annual production of approximately 545 million tons. However, much of this RH remains underutilized, particularly …
Introduction: Coumarins, whether of natural or synthetic origin, represent a large and diverse family of heterocyclic compounds characterized by a benzopyrone (1,2-benzopyrone or α-pyrone) core structure. These compounds are widely distributed in the plant kingdom and have attracted considerable attention due to their broad spectrum of biological and pharmacological activities. …
Introduction: Over the past three decades, synthetic chemists have been striving to improve human life by minimizing chemical pollution. Significant research efforts have focused on designing chemicals and synthetic processes that are less harmful to human health and the environment by employing environmentally benign methodologies of chemical synthesis. Techniques such …
