lol this thread
I'm looking hard for decent and reasonable disso's, so I'll be jumping on this if it is not as expensive as 2-fluoro-DCK.
Mazzy nobody knows for sure as you probably realize, but in truth I would be surprised if the 2-substitution made much of a difference. For a drug's action on receptors, the exact structure is a big deal and minor changes can have extreme consequences for activity of a drug. However for bladder toxicity presumably the irritant nature of ACA metabolites is the culprit, which is not action on receptors but general action on all tissues exposed; and physical properties don't tend to change as wildly if you modify a structure in a relatively minor way.
I really hope this TFM is like a heavy K version, the 2-fluoro was nice but like K light. Nice at moderate doses as a pleasant drug, but that's a different game than dissociating hard which I imagine is costly with 2-fluoro (I haven't taken it that far, my sample and circumstance wouldn't allow it).
What I really hope is that this does not go in a 2-methoxy-DCK direction which I found pretty horrible, but luckily TFM is different enough from a methoxy.
TFM is a group used in drugs as a bioisostere to mimic e.g. chloride or methyl. But I'd forget the latter cause of the polarity difference. I imagine that's kinda what's wrong with a methoxy for placement on the 2-pos of ket.
