Biological target: SR17018 is an mu-opioid-receptor (MOR) agonist, binding with GTPγS, with an EC50 of 97 nM.
In vitro activity: TBD
In vivo activity: The onset of tolerance and dependence for oxycodone was tested and assessed for neurochemical changes associated with prolonged treatment with the biased agonist SR-17018. Male C57BL/6 mice treated for 6 days with SR-17018 at 24 mg/kg/day produces no tolerance, whereas a slight decrease in potency is observed when administered at 48 mg/kg/day. Female mice, treated in the same manner with SR-17018 at 48 mg/kg/day, do not display tolerance (Supplementary Fig. 2 and Table 1). MOR activation was intact in SR-17018-treated mice compared with vehicle-treated mice (Fig. 1g, h). For the SR-17018-treated group, no signs of withdrawal were observed at 3 and 6 h after the last 24 mg/kg, p.o. dose of SR-17018, which is consistent with the pharmacokinetic data supporting the presence of SR-17018 at 6 h (Fig. 2b, Fig. 1a, and Supplementary Fig. 1A,B). Withdrawal signs presented at 13 h after the last p.o. dose of SR-17018 and were recorded for 3 days at the time shown (Fig. 2b). A comparison of the sum of the withdrawal signs collected from the first signs of withdrawal over 3 days (from 1 to 72 h for morphine and from 13 to 84 h for SR-17018) to their respective controls demonstrates that chronic treatment with either compound produces significant withdrawal (morphine vs. saline; p < 0.05; SR-17018 vs. vehicle, p < 0.01, two-way ANOVA, Fig. 2a, b). The SR-17018-treated animals return to vehicle control levels by 48 h, whereas the morphine-treated group continue to show signs of withdrawal 3 days after the initial onset of withdrawal as compared with saline-treated mice.This proposes that SR-17018 has the characteristics of performing as a stabilizing agonist at MOR whereupon chronic treatment stabilizes a G protein coupling state and may represent a means to restore MOR responsiveness and analgesic efficacy in the opioid-dependent state, while lessening the severity of opiate withdrawal.
