- The following structure is more active than morphine as an analgesic. H3C N. CH3 H. H3C O .. What is the principal reason for this? O The extra acetyl group binds to cell surface receptors improving active internalization. O The acetyl groups mask a polar group allowing the structure to cross the blood brain barrier more efficiently. O The extra acetyl group masks an alcohol group which would otherwise undergo a phase Il metabolic conjugation reaction leading to rapid excretion of the drug. O The acetyl groups increase the stability of the drug in the cellular environment. O ..Which of these heterocyclic drugs is likely to be the least soluble in water? Use the Fsp³ parameter to decide.
