Three-Day Continuous Oxytocin Infusion Attenuates Thermal and Mechanical Nociception by Rescuing Neuronal Chloride Homeostasis Upregulation KCC2 Expression and Function.

Oxytocin (OT) and its receptor are promising targets for the treatment and prevention of the neuropathic pain. In the present study, we compared the effects of a single and continuous intrathecal infusion of OT on nerve injury-induced neuropathic pain behaviours in mice and further explore the mechanisms underlying their analgesic properties. We found that three days of continuous intrathecal OT infusion alleviated subsequent pain behaviours for 14 days, whereas a single OT injection induced a transient analgesia for 30 min, suggesting that only continuous intrathecal OT attenuated the establishment and development of neuropathic pain behaviours.

Design, synthesis and biological evaluation of dual mTOR/HDAC6 inhibitors in MDA-MB-231 cells.

The excessive activation of histone deacetylase (HDAC) and mammalian target of rapamycin (mTOR) signaling promotes tumor growth and progression. We proposed that dual targeting mTOR and HDAC inhibitors is a promising strategy for triple negative breast cancer (TNBC) treatment. In this study, a series of dual mTOR/HDAC6 inhibitors were designed and synthesized by structure-based strategy.
