1-Aminocyclopropane-1-carboxylic acid is an endogenous metabolite. In the presence of low concentrations (1 μM) of glutamate, 1-Aminocyclopropane-1-carboxylic acid acts as a small molecule agonist of NMDA receptors with an EC50 of 0.7-0.9 μM. At high concentrations (10 μM) of glutamate, 1-Aminocyclopropane-1-carboxylic acid acts as a competitive antagonist of NMDA receptors with an EC50 of 81.6 nM. 1-Aminocyclopropane-1-carboxylic acid exerts neuroprotective activity by moderately activating NMDA receptors to prevent neuronal cell death in ischemic animal models. Additionally, 1-Aminocyclopropane-1-carboxylic acid is an antagonist of NMDA receptors, inducing blood pressure reduction and antioxidant effects in stroke-prone hypertensive rats. 1-Aminocyclopropane-1-carboxylic acid enhances object recognition memory and cognitive flexibility dependent on the prefrontal cortex, but does not affect impulsivity nor exhibit an antipsychotic-like profile. 1-Aminocyclopropane-1-carboxylic acid shows promise for research in the field of neurotoxicity. .

Photoswitchable PM8 is a fluorescent probe used for super-resolution imaging of the plasma membrane. Photoswitchable PM8 functions through a light-induced Z/E isomerization mechanism: in the hydrophobic cell membrane environment, the Z isomer forms a planar intramolecular charge transfer state stabilized by an intramolecular hydrogen bond, which restricts conformational freedom, reduces nonradiative decay, and produces bright fluorescence; in contrast, the E isomer lacks this hydrogen bond, has increased conformational freedom, and exhibits a fluorescence-quenched state. The fluorescence of Photoswitchable PM8 can be switched "on/off" by visible light: activation with 405 nm light forms the fluorescent Z isomer, and switching with 561 nm light converts it to the nonfluorescent E isomer. In the membrane environment, Photoswitchable PM8 enables single-molecule localization for super-resolution imaging. Due to solvent-induced quenching and aggregation, Photoswitchable PM8 has negligible fluorescence in aqueous solution, but upon binding to the hydrophobic membrane environment it produces bright fluorescence, enabling high signal-to-noise ratio imaging without washing .
