AM-1241 (1-(methylpiperidin-2-ylmethyl)-3-(2-iodo-5-nitrobenzoyl)indole) is a chemical from the aminoalkylindole family that acts as a potent and selective agonist for the cannabinoid receptor CB2,[1][2] with a Ki of 3.4 nM at CB2 and 80 times selectivity over the related CB1 receptor.[3][4] It has analgesic effects in animal studies, particularly against "atypical" pain such as hyperalgesia and allodynia.[5] This is thought to be mediated through CB2-mediated peripheral release of endogenous opioid peptides,[6] as well as direct activation of the TRPA1 channel.[7] It has also shown efficacy in the treatment of amyotrophic lateral sclerosis in animal models.[8][9]

Effects in bone cancer model

The antihyperalgesic effects of AM-1241 were investigated in a murine bone cancer model. Sarcoma cells were injected into the femur of a mouse, and then mice were injected twice daily with AM-1241. Treatment with AM-1241 reduced both spontaneous and evoked pain, as well as reducing the bone loss and subsequent fractures due to the tumor. Pretreatment with the CB2 antagonist SR-144,528 reversed the acute effects of AM-1241 on both spontaneous and evoked pain, while having no effect on its own.[10]
