QBS10072S
QBS10072S is a LAT1-selective substrate with blood-brain barrier permeability that inhibits tumor growth. QBS10072S enters LAT1-expressing tumor cells via LAT1-mediated active transport, induces interstrand DNA cross-linking and cell apoptosis, and reduces leptomeningeal dissemination. QBS10072S can be used in studies related to glioblastoma multiforme, diffuse intrinsic pontine glioma, triple-negative breast cancer brain metastases, and aggressive T-cell lymphoma.

Biological Activity
QBS10072S induces significant cytotoxicity in LAT1-expressing GBM cell lines (including those with high and low MGMT expression) and minimal cytotoxicity in LAT1-negative normal human astrocytes[1].
QBS10072S is preferentially cytotoxic to human TNBC cell lines (MDA-MB-157, MDA-MB-468, HCC1806, DU4475, MDA-MB-231-BR3, MDA-MB-231, HCC1937, BT-549) with LC50 values of 1 to 10 μM, while human ER-positive breast cancer cell lines (MCF-7, EMT6) are less sensitive[2].
QBS10072S (log[QBS] = -9 to log[QBS] = -3) induces dose-dependent cytotoxicity in human TNBC MDA-MB-231 cells[2].
QBS10072S induces dose-dependent cytotoxicity in LAT1-positive Hut78, HH, MJ, and H9 T-cell lymphoma cell lines[3].

QBS10072S (8 mg/kg; i.v.; once a week; 9 weeks; i.p.; twice a week; 9 weeks) significantly reduces intracranial tumor growth, extends survival, and decreases leptomeningeal dissemination in a TNBC brain metastasis model with no obvious toxicity[2].
