The molecule is an organic heterooctacyclic compound that is 1H,1'H-2,2'-biindole in which the nitrogens have undergone formal oxidative coupling to positions 2 and 5 of 3-amino-N,2-dimethyloxolane-3-carboxamide (the 2R,3R,5S product), and in which the 3 and 3' positions of the biindole moiety have also undergone formal oxidative coupling to positions 3 and 4 of 1,5-dihydro-2H-pyrrol-2-one. It has a role as an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor and an antineoplastic agent. It is a gamma-lactam, a hemiaminal, an indolocarbazole, an organic heterooctacyclic compound, a monocarboxylic acid amide, a primary amino compound and a bridged compound.
