Some of the hybrid compounds exhibited promising trypanocidal and anticancer activities.
Three decades after A. P. de Silva’s seminal paper introduced the concept of logic gates at molecular level, field (MLGs) has witnessed significant advancements. MLGs are devices designed to perform logical operations, utilizing one or more physical chemical stimulus signals (inputs) generate an output response. Notably, have found diverse applications, with optical detection analytes emerging as a notable evolution traditional chemosensors. Organic synthesis methods pivotal in crafting...
BTDs (2,1,3-benzothiadiazoles) are fluorescent heterocycles widely used in different applications, including biomarkers, sensing optical devices, OLEDs, organic transistors, and solar cells. This review mainly focuses on the current progress design of compounds derived from BTD core, aiming for their use as chromogenic and/or fluorogenic devices detecting anionic, cationic, neutral analytes. Reactions synthetic strategies that show versatility initially presented, to provide a better...
Optical detection devices have become an analytical tool of interest in diverse fields science. The search for methods to identify and quantify different compounds has transposed this curiosity into a necessity, since some constituents threaten the safety life all its forms. In context, 30 years ago, Prof. Prasanna de Silva presented idea sensors as Molecular Logic Gates (MLGs): molecule that performs logical operation based on one or more inputs (analytes) resulting output (optical...
Abstract Sesquiterpene lactones (SL) represent a class of secondary metabolites found in the Asteraceae family, notable for their unique structures. The SL α‐santonin ( 1 ) and its derivatives are worthy mention due to diverse biological properties. Additionally, 4 H ‐chromenes ‐chromones appealing frameworks holding capability be used as structural motifs new drugs. Furthermore, unambiguous elucidation is crucial developing novel compounds applications. In this context, it common find...
Sesquiterpene lactones (SLs) have in their skeleton fifteen carbons and constitute a group of compounds with several biological activities. Because wide spectra activities related ecological role as defense compounds, we selected chromenediones one the most promising candidates for further studies. According to IUPAC nomenclature chromene is polycyclic organic compound formed from fusion benzene ring heterocyclic pyran ring. α- Santonin, commercially available eudesmanolide, was employed...
