The classical histamine H1‐receptor antagonists diphenhydramine (3a) and cyproheptadine (9) and their derivatives (3b—d, 10) were connected with a 2‐guanidinothiazole containing structure (28) derived from the H2‐receptor antagonist tiotidine in order to obtain combined H1‐/H2‐receptor antagonists. The two moieties were not directly linked together, but were separated by a polymethylene spacer and
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
