DBPR116 is a prodrug of BPRMU191 with blood-brain barrier penetration capability. DBPR116 significantly improves the delivery of centrally targeted drugs. In combination with the antagonist Naltrexone, DBPR116 demonstrated superior safety and analgesic efficacy compared to morphine in various in vivo pharmacological studies, including thermal pain models, cancer pain models, constipation, sedation, psychological dependence, heart rate, and respiratory frequency. As a prodrug strategy for peripheral administration, DBPR116 effectively alleviates pain while reducing adverse effects, showing potential as a safer opioid analgesic.
