"Would polyamines prutenscine and cadaverine have the same effect? Or simple branded amines like trimathylamine?"

Interesting idea! To date, our research has focused on the polyamine spermidine
emerging from the work done by Dr. Frank Madeo's lab. It appears that a combination
of polyamines putracine, spermidine and spermine are valuable, there is some
evidence that cadaverine can be toxic. To date the majority of longevity benefit research
extends from spermidine's strength as an autophagy trigger. This may change with
additional research, but this how we interpret he research to date.
