YK-5-252 is a dual action combretastatin A-4 (CA-4) prodrug which releases CA-4 through a disulfide bond cleavage mechanism and contains a near-infrared (NIR) fluorophore.
The renin fluorogenic substrate consists of the normal peptide substrate for renin which has been linked to the fluorophore EDANS at one end and to a non-fluorescent quenching molecule (Dabcyl) at the other. After cleavage by renin, the product (peptide-EDANS) is brightly fluorescent and can be easily analyzed using an excitation wavelength of 340 nm and emission wavelengths of 485-510 nm.
N-Descyclopropanecarbaldehyde Olaparib, an Olaparib analogue, incorporates a DOTA moiety. It acts as a CRBN-based ligand for the formation of novel dual EGFR and PARP PROTAC, DP-C-4[1]. N-Descyclopropanecarbaldehyde Olaparib is suitable for radiolabeling with F-18 or a fluorophore to visualize tumors using positron emission tomography (PET) or optical imaging[2].
Coumarin-quinone conjugate is a fluorescent substrate for NADH:ubiquinone oxidoreductases.1It is comprised of a coumarin fluorophore conjugated to a ubiquinone analog that can be reduced by NADH:ubiquinone oxidoreductases. It has been used to measure the kinetic parameters of apoptosis-inducing factor mitochondria-associated 2/ferroptosis suppressor protein 1 (AIFM2/FSP1). 1.Doll, S., Freitas, F.P., Shah, R., et al.FSP1 is a glutathione-independent ferroptosis suppressorNature575(7784)693-698(2019)
Diacylglycerols (DAG) are generated through the hydrolysis of membrane phospholipids and function as lipid second messengers by activating protein kinase C (PKC) and modulating cell growth and apoptosis. Additionally, they act as precursors for DAG kinases in the synthesis of phosphatidic acid, a crucial lipid messenger. The compound 1-NBD-decanoyl-2-decanoyl-sn-glycerol incorporates a nitrobenzoxadiazole (NBD) fluorophore at the ω-end of its terminal decanoyl chain, using the structure of 1,2-didecanoyl-sn-glycerol as a model for diacylglycerol. This molecule is expected to exhibit excitation and emission peaks at roughly 470/541 nm, paralleling those of various NBD-labeled phospholipids. Fluorescently labeled lipids, such as this, are instrumental in exploring their interactions with proteins, their uptake by cells and liposomes, and in developing assays for lipid metabolism research.
