Enalapril maleate is used in research related to asymptomatic left ventricular dysfunction, congestive heart failure, Alzheimer's disease, diabetes mellitus, acute myocardial infarction, atrial fibrillation, hypertension, cerebral ischemia, chronic heart failure, and single-ventricle physiology .
Cat. No.: HY-D3438
Target:
Research Areas:
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 .

7,106 compounds
G protein-coupled receptors (GPCRs) are membrane proteins in humans and one of the most important targets in drug discovery. Approximately 35% of launched drugs are targeted GPCRs, making them a crucial class of targets in drug discovery.
The orthosteric site of a GPCR is its endogenous ligand’s (such as neurotransmitters or hormones) binding site. This site plays a central role in signal transduction. Small molecules binding to this site typically contain a protonatable amino group, enabling the formation of salt bridges or hydrogen bonds with acidic residues in the binding pocket. In contrast, the allosteric site does not directly initiate signaling but modulates the signal intensity of the GPCR by altering or stabilizing the conformation of the orthosteric site. Small molecules binding to the allosteric site often contain multiple aromatic rings to occupy hydrophobic pockets and achieve their functional effects.
MCE has collected over 7,106 reported bioactive molecules targeting GPCRs, covering Class A, B, and C GPCRs. These small molecules were subjected to AI representation to extract 2D and 3D features. Subsequently, we do screening by AI score based on similarity to identify molecules in diversity library highly similar to the reported bioactive molecules in both 2D and 3D, with a threshold greater than 0.7. Further screening based on cLogP was applied to select molecules with good lipophilicity, which facilitates the binding of small molecules to GPCRs. This diversity library can be widely applied to the discovery of compounds targeting GPCR proteins.
