Application

Syrosingopine has been used as a monocarboxylate transporter (MCT) inhibitor

to study its effects on anti-CD147-induced metabolon disruption in human breast cancer cells
to study its effects on Cryptosporidium parvum-infected HCT-8 cells
in orthogonal linear separation analysis (OLSA)-derived decomposed analysis

Biochem/physiol Actions

Syrosingopine is a derivative of reserpine and inhibits monocarboxylate lactate transporters 1 and 4 (MCT1/4).

Syrosingopine is an antihypertensive agent related to reserpine that was found to potentiate the anticancer effects of the antidiabetic agent metformin and phenformin without harmful effects on normal cells. Syrosingopine was also found to potentiate the anticancer activity of mitochondrial electron transport chain (ETC) inhibitors. Its mechanism of action is currently unknown but may involve inhibition of glycolytic enzyme α-enolase rather than its known activity as an inhibitor of vesicular monoamine transporters VMAT1 and VMAT2.

Syrosingopine sensitizes cancer cells to killing by metformin.

Don Benjamin et al.

Science advances, 2(12), e1601756-e1601756 (2016-12-29)

We report that the anticancer activity of the widely used diabetic drug metformin is strongly potentiated by syrosingopine. Synthetic lethality elicited by combining the two drugs is synergistic and specific to transformed cells. This effect is unrelated to syrosingopine's known

Metabolic Signatures of Cryptosporidium parvum-Infected HCT-8 Cells and Impact of Selected Metabolic Inhibitors on C. parvum Infection under Physioxia and Hyperoxia.

Juan Vélez et al.

Biology, 10(1) (2021-01-21)

Cryptosporidium parvum is an apicomplexan zoonotic parasite recognized as the second leading-cause of diarrhoea-induced mortality in children. In contrast to other apicomplexans, C.

CAIX forms a transport metabolon with monocarboxylate transporters in human breast cancer cells.

Samantha Ames et al.

Oncogene, 39(8), 1710-1723 (2019-11-15)

Tumor cells rely on glycolysis to meet their elevated demand for energy. Thereby they produce significant amounts of lactate and protons, which are exported via monocarboxylate transporters (MCTs), supporting the formation of an acidic microenvironment. The present study demonstrates that
