Organoselenium-based quinoline sensor for superoxide detection and its antitumor activities
Quinoline-based “turn-on” fluorescent probe was successfully synthesized using 5-amino quinoline and 2-(phenylselanyl)benzaldehyde. The probe was found to be selective for superoxide over other reactive oxygen species (ROS) and biothiols. The probe can detect superoxide in the presence of other ROS and biothiols. The detection limit of the probe for superoxide was found to be 37 nM with a Stokes shift of 150 nm. The probe quickly detects superoxide with a 21-fold increase in fluorescence intensity. The probe exhibited anticancer activity on HeLa cells that was comparable to the standard drug (Cisplatin).
Graphical abstract
Organoselenium based quinoline probe was developed. The probe was selective for superoxide with instant response and possess good anticancer activity.
期刊介绍：
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
