2,3 diaminonaphthalene

2,3-Diaminonaphthalene is a highly selective fluorometric and colorimetric reagent for selenium detection and also used for the fluorometric determination of nitrite.

1-Palmitoyl-2-[3-(diphenylhexatriene)propanoyl]-sn-phosphatidylcholine, featuring a phosphatidylethanolamine head group, serves as a fluorescent probe to assess surface lipid oxidation in lipoproteins and plasma [1].

3-Methyl-8-(2'-deoxy-β-D-ribofuranosyl)isoxanthopterin serves as a pteridine-based fluorescent guanosine analogue and DNA uptake tracer utilized extensively for investigation into DNA binding and dynamics. It exhibits an absorbance peak at 350 nm and a corresponding emission peak at 430 nm [1].

2'(3')-O-Anthraniloyladenosine-5'-O-triphosphate (2'-ANT-ATP) and its isomer 3'-ANT-ATP are fluorescent derivatives of ATP that spontaneously isomerize. Emitting a maximum light of 428 nm when excited at 330 nm in water, 2'(3')-ANT-ATP specifically inhibits several types of adenylyl cyclase (AC) including mammalian AC1, AC2, and AC5 with inhibition constants (Kis) of 130, 640, and 120 nM, respectively. It also inhibits Bordetella pertussis AC toxin CyaA with Kis of 1.3 µM (in the presence of manganese) and 20 µM (in the presence of magnesium), Bacillus anthracis AC toxin edema factor with Kis of 0.44 µM (with manganese) and 5.15 µM (with magnesium), and Escherichia coli recombinase A (RecA) with a Ki of 6.3 µM.

2'(3')-O-Anthraniloylguanosine-5'-O-triphosphate (2'-ANT-GTP) and 3'-ANT-GTP are fluorescent derivatives of GTP that exhibit spontaneous isomerization. 2'(3')-ANT-GTP features an emission peak at 428 nm when excited at 330 nm in aqueous conditions. It functions as an inhibitor of several adenylyl cyclases, notably mammalian adenylyl cyclase 1 (AC1; Ki = 10 nM with manganese), inhibits B. anthracis adenylyl cyclase toxin edema factor (Kis = 4.1 and 13 µM with manganese and magnesium, respectively), and B. pertussis adenylyl cyclase toxin CyaA (Ki = 29 µM with manganese).

AMCA-X, N-succinimidyl ester is an amine-reactive, UV-excitable, blue fluroscent dye.

2,5-Dioxopyrrolidin-1-yl 2-(7-hydroxy-4-methyl-2-oxo-2H-chromen-3-yl)acetate is a useful organic compound for research related to life sciences. The catalog number is T67683 and the CAS number is 96735-88-5.

Compound 5, 2,3-Di(furan-2-yl)quinoxaline, is a blue-fluorescent quinoxaline derivative that is cell-permeable and demonstrates sufficient brightness at a micromolar concentration of 1.5 μM [1].
