AZD-3965

Research use only, not for human use.

AZD3965 is a selective inhibitor of monocarboxylate transporter 1 (MCT1).

AZD3965 is a selective inhibitor of monocarboxylate transporter 1 (MCT1) with a binding affinity of 1.6 nM, is 6 fold selective over MCT2 and does not inhibit MCT4 at 10 μM. In vivo, AZD3965 is well tolerated and induces a dose and time dependent accumulation of lactate in the tumours, suppresses tumour growth and in the Raji model potentiates the effects of Rituxan, doxorubicin and bendamustine. The selective inhibition of lactate transport by the MCT1 inhibitor AZD3965 offers an novel mechanism for targeting the metabolic phenotype in tumours that preferentially express MCT1.(In Vitro):AZD3965 is designed to selectively inhibit Monocarboxylate transporter-1 (MCT1) and will therefore be expected to influence the movement of lactate into and out of cells. AZD3965 treatment causes a 3.7 fold increase in intracellular lactate in hypoxic COR-L103 and 3.7 fold and 3.9 fold increases in normoxic and hypoxic NCI-H1048 cells respectively. In all other cases a <1.9 fold increase is observed. These data are consistent with AZD3965 blocking lactate transport in cells where AZD3965 also reduces cell number and is consistent with AZD3965 acting via inhibition of MCT1. When MCT1 is overexpressed the EC50 of NCI-H1048 is increased from 0.14 nM to 10.5 nM in NCI-H1048 cells. This is consistent with AZD3965 acting via MCT1 inhibition. (In Vivo):COR-L103 tumor bearing mice are treated with 100 mg/kg AZD3965 or vehicle BIDfor 21 days and the tumor volume monitored. Pharmacokinetic analysis demonstrates that 100 mg/kg AZD3965 BID results in concentrations of free AZD3965 predicted to inhibit lactate transport. AZD3965 treatment significantly reduces the growth of COR-L103 tumors, although tumor regression is not seen, consistent with AZD3965 only targeting the hypoxic fraction of the tumor.
