Iminodibenzyl redirected cyclooxygenase-2 catalyzed dihomo-γ-linolenic acid peroxidation pattern in lung cancer

L Pang, H Shah, S Qian, V Sathish - Free Radical Biology and Medicine, 2021 - Elsevier
Abstract Cyclooxygenase-2 (COX-2) is up-regulated by redox imbalance and is considered
a target for cancer therapy. The rationale of the COX-2 inhibitor lies in suppressing COX-2 …
