User: I want to know more about the molecule with SMILES CC(=O)OC/C=C(C)/C=C/C=C(C)/C=C/C1=C(C)CCCC1(C)C.
Assistant: That sounds interesting, how can I help?
User: Please describe this drug.
Assistant: The answer is Retinyl Acetate is a naturally-occurring fatty acid ester form of retinol (vitamin A) with potential antineoplastic and chemopreventive activities.  Retinyl acetate binds to and activates retinoid receptors, inducing cell differentiation and decreasing cell proliferation.  This agent also inhibits carcinogen-induced neoplastic transformation in some cancer cell types and exhibits immunomodulatory properties. (NCI04)
