Even if it isn't covalently binding, super high affinity for the target isn't that desirable because it can lead to rapid and pronounced tachyphylaxis (i.e. effects will quickly become weaker and weaker with repeated doses). Look at lofentanil for instance, that doesn't bind covalently but it desensitizes opioid receptors just as well as oxymorphazone, which does bind covalently.
That said, I tend to agree with the above statements that the Ki value of 0.08nM for AM-694 is likely erroneous given that the Ki for the 2-methyl analogue AM-2225 is so many times higher! Really you would think the peer review process for granting a patent should be far more stringent than for publishing an article in the scientific literature, considering the legal rights that a patent provides, but unfortunately this does not seem to be the case.
