Task: Please create a molecule SMILES based on the text description below.
Description: The molecule is an oxaspiro compound that is 1,6-dioxaspiro[4.4]non-2-en-4-one substituted by a carboxymethyl group at position 2, carboxy groups at positions 2 and 3, an oxo group at position 9 and a nonyl group at position 8. Isolated from the culture broth of the fungus Talaromyces trachyspermus, it exhibits inhibitory activity against the enzyme heparanase. It has a role as a fungal metabolite and an EC 3.2.1.166 (heparanase) inhibitor. It is an oxaspiro compound and a tricarboxylic acid.
Result: CCCCCCCCCC1=COC2(CC(C(=O)O)C(CC(=O)O)(C(=O)O)O2)C1=O
