4-N-Nonyloxyphenol (4-nonoxyphenol), a heterogeneous photosensitizer based on kaolinite nanotubes, is a widely used pesticide and endocrine disruptor for the photodegradation of phenol-based pesticides.

2'-Hydroxychalcone is a drug synthesis intermediate for the synthesis of flavonoids. 2'-Hydroxychalcone loaded in nanoemulsion showed fungicidal activity against Coccidioides parapsilosis in Danio rerio model.2'-Hydroxychalcone induced cytotoxicity through oxidative stress in lipid-loaded Hepg2 cells.2'-Hydroxychalcone inhibited the induction of ICAM-1, VCAM-α, tumor necrosis factor-α, and tumor necrosis factor-alpha as determined by reverse transcription-polymerase chain reaction determined by tumor necrosis factor-alpha induces steady-state transcript levels of ICAM-1, VCAM-1, and E-selectin, and therefore may interfere with the transcription of their genes.

Potent and selective KV1.3 channel blocker (IC50 values are 0.0019 and 0.65 nM for KV1.3 and KV1.1, respectively). Inhibits CD4+ CCR7- T cell activation. Ameliorates rat experimental autoimmune encephalomyelitis, in a model for multiple sclerosis.
