Levamlodipine besylate hemipentahydrate is relevant for research in vascular dementia, hypertension, and cerebrovascular diseases.

Herbicide safener-4 (Compound I-15) is a herbicide safener designed to enhance crop resistance to herbicides without diminishing the herbicidal effects on target weeds. It competitively binds to the ALS active site alongside Mesosulfuron-methyl. In addition, Herbicide safener-4 boosts the activities of glutathione GSH, glutathione-S-transferase GST, cytochrome P450 CYP450, peroxidase (POD), superoxide dismutase (SOD), and acetolactate synthase (ALS) within plants.

Mn(III)TMPyP is a manganese-porphyrin which acts as a superoxide dismutase (SOD) mimetic and peroxynitrite decomposition catalyst. SOD mimetics described to date are unstable and are capable of catalyzing undesired side-reactions in addition to the dismutation of the superoxide radical (O2-). Mn(III)TMPyP is an SOD mimetic with increased stability to pH and hydrogen peroxide.
