Well Flubatine is being used on human test subjects. {Based on the name of flubatine I was able to decipher homoepibatidines alternative name Clobatine.}Long ago someone asked me to find a possible nicotine alternative and so knowin epibatidine acts on similar sites, I took a deep dive into the various derivatives. At the time several were being investigated as possible new analgesics. The problem researchers always ran into was the toxicity of such compounds.
I don;t think I found the latter compound and it's important because it doesn't contain the 2-chloro-5-pyridyl moiety that appeared to be the cause of toxicity - I suspect because it engendered too much affinity for unwanted subtypes.
But it's 20+ years later and it seems like research in the field has slowed down.
My GUESS is that those biased opiate ligands proved to be more fruitful. I'm ALWAYS very cautious when a startup sells a novel opioid on the basis that it has little to no abuse potential. From buprenorphine to pentazocine to tramasol & tapentadol. Every generation SOMEONE introduces a new class and thusfar, without exception, people abuse them. In fact, sometimes the WAY they are abused actually increases the risk to the user. Mixing first-generation antihistamines seems to reliably increase the subjective euphoria of all opioids.
Tramadol, well, we all saw the number of fatalities that caused and The Lancet reported that in some patients at least, tapentadol produced a particularly nasty dependence, possibly because although it has low affinity, it appears to be a SUPERagonist i.e. it's agonist activity is greater than DAMGO.
I've mentioned it before, but simply replacing the benzylic ethyl side-chain of tapentadol with an N-propyl will produce a much more potent agent. The researchers were VERY careful not to even test anything BUT the ethyl. Clearly they noted that tapentadol overlaid the active conformation of picenadol (whose researcher DID try various chain-lengths). So, given the synthetic simplicity, tahexadol seems a likely future RC. How to get it made? Find a Chinese tapentadol producer - tahexadol would be legal in China and the Chinese are so refreshingly pragmatic when it comes to money. As long as you have a believable story - they WILL believe you. How GOOD the story is will be reflected in the price l-)
