Task: Answer the following question about the molecule with SMILES CC1=C(CCC(=O)O)c2cc3nc(cc4[nH]c(cc5[nH]c(cc1n2)c(C)c5C(C)O)c(C)c4C(C)O)C(C)=C3CCC(=O)O.
Description: Please describe this drug.
Completion: Iron-free derivatives of heme with 4 methyl groups, 2 hydroxyethyl groups and 2 propionic acid groups attached to the pyrrole rings. Some of these PHOTOSENSITIZING AGENTS are used in the PHOTOTHERAPY of malignant NEOPLASMS.
