Bioactivity | Syrosingopine (Su 3118) is an orally active lactate transporters (MCT1/MCT4) dual inhibitor, which can reduce glycolysis and induce synthetic lethality in cancer cells when combine with metformin. Syrosingopine shows anti-hypertensive activity by depleting peripheral stores of norepinephrine[1][2]. |
Target | MCT1 and MCT4 |
Invitro | Syrosingopine (10 µM; 1, 3, 4 hours) causes accumulation of intracellular lactate after 1 hour and peaks at 4 hours, which lead to intracellular acidification in HeLa cells[1].Syrosingopine (10 µM; 1, 2 hours) slows lactate efflux by inhibiting MCT4 and MCT1 in MCT1-KO and MCT4-KO HAP1 cells, respectively[1].Syrosingopine (10-100 µM)-metformin combination induces synthetic lethality by inhibiting transport of lactate in HAP1 MCT1-KO cells[1].

In Vivo | Syrosingopine (5 mg/kg; s.c.; once) shows anti-hypertensive activity which as low as the result after ganglionic blockade by depleting peripheral stores of norepinephrine[2]. Animal Model: |
