Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate, is researched, Molecular C18H20N2O12, CAS is 70539-42-3, about Characterization and affinity cross-linking of receptors for human recombinant lymphotoxin (tumor necrosis factor-β) on a human histiocytic lymphoma cell line, U-937. Author is Stauber, Gregory B.; Aggarwal, Bharat B..
Recombinant human lymphotoxin (rhLT) was purified and used to examine its receptors on the human histiocytic lymphoma cell line U-937. The rhLT was radioiodinated by the IODO GEN method to a specific activity of 60 μCi/μg. The specific binding reached a plateau within 10, 60, and 180 min at 37, 23, and 4°, resp. Scatchard anal. revealed the presence of a single class of high affinity receptors with an apparent Kd of 0.6 nm and a capacity of 33,000 binding sites/cell. The binding of 125I-labeled rhLT to U-937 cells was inhibited by excess unlabeled rhLT or recombinant human tumor necrosis factor-α(rhTNF), suggesting a common receptor for both mols. The crosslinking of the receptor to rhLT revealed 2 distinct bands at approx. mol. masses of 100,000 and 120,000 daltons. Affinity crosslinking of U-937 cells with 125I-labeled rhTNF, however, provided only a single band with a mol. mass of about 100,000 daltons. Thus, the manner in which rhLT interacts with its receptor is perhaps somewhat different from that of rhTNF.
