Opioids and Their Receptors: Present and Emerging Concepts in Opioid Drug Discovery II

Dear Colleagues,

Following the successful first edition of the Special Issue “Opioids and Their Receptors: Present and Emerging Concepts in Opioid Drug Discovery” (https://www.mdpi.com/journal/molecules/special_issues/Opioid_Drug), the second edition of this Special Issue aims to gather works on the latest chemical and pharmacological developments in opioid research, with further understanding of opioids and opioid receptor-mediated actions and the search for alternative treatments for pain and other human disorders where the opioid system plays an central role. A special attention is drawn to advancing concepts in opioid drug discovery in the light of the current opioid crisis. Studies investigating interactions between the opioid system and coronavirus disease 2019 (COVID-19) will also be suitable for this Special Issue.

We give thanks for past contributions and look forward to receiving new contributions as original articles, short communications, and reviews on the challenging aspects of the opioid research field, ranging from basic science to translational research.
