MedKoo CAT#: 206040

CAS#: 1448671-31-5

Description: 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.

Additional Information

AZD3965 sensitivity varied in vitro and was highest in hypoxia. Resistance in hypoxia was associated with increased MCT4 expression. In vivo, AZD3965 reduced tumor growth and increased intra-tumor lactate. In the tissue microarray, high MCT1 expression was associated with worse prognosis (p=0.014). MCT1 and hypoxia marker CA IX expression in the absence of MCT4 was observed in 21% of SCLC tumor
