Task: Please generate a SMILES based on the description.
Description: The molecule is a tricarboxylic acid trianion obtained by deprotonation of the three carboxy groups of 2,2',2''-[10-(2-hydroxypropyl)-1,4,7,10-tetraazacyclododecane-1,4,7-triyl]triacetic acid (HP-DO3A). It is a conjugate base of a H3HP-DO3A.
Result: CC(O)CN1CCN(CC(=O)[O-])CCN(CC(=O)[O-])CCN(CC(=O)[O-])CC1
