(±)-5'-Chloro-5'-deoxy-ENBA is a selective and high-affinity adenosine A1 receptor agonist with Ki values of 0.51 [1].
Adenosine A1 receptor mediated neuroand cardioprotection (an antiarrhythmic effect), reduction of lipolysis in adipose tissue and reduction of neuropathic pain [1].
In mice injected with formalin at doses between 1 and 2mg/kg, (±)-5'-Chloro-5'-deoxy-ENBA inhibited the first and the second phases of the nocifensive response induced by formalin [1]. In a mouse model of neuropathic pain (the Spared Nerve Injury (SNI) of the sciatic nerve), (±)-5'-Chloro-5'-deoxy-ENBA (0.5 mg/kg) reduced thermal hyperalgesia and mechanical allodynia 7 and 3 days post-SNI without significantly changed the motor coordination and arterial blood pressure. Also, (±)-5'-Chloro-5'-deoxy-ENBA chronic treatment reduced activated and hypertrophic microglia [2]. In a Parkinson's disease (PD) mouse model, (±)-5'-Chloro-5'-deoxy-ENBA prevented the increase in sIPSC frequency and eIPSC amplitude produced by SKF. In mice with unilateral DA denervation, (±)-5'-Chloro-5'-deoxy-ENBA reduced the development of abnormal involuntary movements induced by L-DOPA [3].
