Set7/9 is a histone lysine methyltransferase, but it is also thought to be involved in a wide variety of pathophysiological functions. We previously identified cyproheptadine, which has a characteristic butterfly-like molecular conformation with bent tricyclic dibenzosuberene and chair-form N-methylpiperidine moieties, as a Set7/9 inhibitor. In this work, we synthesized several derivatives in order to
Treatment of xanthene carbinol 1a or xanthenylidene derivative 2a with refluxing formic acid unexpectedly gave dihydro compound 3a. Thioxanthene and acridine carbinols 1b and 1c and acridinylidene derivative 2c were also partially reduced when treated with formic acid.
