5-HT1AR/5-HT6R ligand-1

5-HT1AR/5-HT6R ligand-1 (Compound PP13) is the ligand for 5-HT receptor that exhibits good affinity to 5-HT1AR, 5-HT6R and 5-HT7R (Ki of 19, 69 and 198 nM, respectively), thereby inhibiting the cAMP production in HEK293 cell with EC50 of 1535, 488 and 53 nM, respectively. 5-HT1AR/5-HT6R ligand-1 exhibits anti-proliferative activity against a variety of cancer cells (IC50 for 1321N1, U87MG, MCF7, and AsPC-1 is 9.6, 13.6, 19.3 and 14.6 μM, respectively) . 5-HT1AR/5-HT6R ligand-1 also exhibits antagonist activity for dopamine receptor D2R with Ki of 1903 nM[1].
