Cyanosafracin B is a compound which can be used in the synthesis of ecteinascidin ET-743 (an antitumor chemotherapy drug).

Narsoplimab (OMS 721) is a selective whole-human immunoglobulin gamma-4 (IgG4) monoclonal antibody and a mannan-binding lectin-associated serine protease-2 (MASP-2) inhibitor that binds MASP-2 to prevent lectin pathway activation and inhibit the agglutinin pathway.

4-Methylumbelliferyl-α-D-Glucopyranoside (4-Methylumbelliferyl-α-D-Glucose) is a fluorescent substrate for α-glucosidase, which releases the fluorescent moiety 4-methylumbelliferyl (4-MU) upon cleavage. 4-MU has pH-dependent fluorescence excitation activity, with excitation wavelengths of 320 nm at low pH (1.97-6.72) and 360 nm at high pH (7.12-10.3), respectively. The emission wavelength of 4-Methylumbelliferyl-α-D-Glucopyranoside increases with decreasing pH, ranging from 445-455 nm. 4-Methylumbelliferyl-α-D-Glucopyranoside can be used as a biomarker for Fabry and Pompe diseases to quantify α-glucosidase activity in infant blood spot samples.
