生物&药学活性

QBS10072S is a novel dual-function, BBB permeable chemotherapeutic agent with alkylating moiety and a selective large neutral amino acid transporter 1 (LAT1, SLC7A5) substrate, shows excellent BBB penetration and promising efficacy in vitro (U251 cell IC50=12 uM) and in vivo against glioblastoma (GBM).
QBS10072S is 50-fold more selective for LAT1 vs. LAT2 in transport assays and demonstrates significant growth suppression in vitro of LAT1-expressing GBM cell lines.
QBS10072S inhibits substrate transport in high LAT1-expressing cells 50-fold more potently compared to LAT2-expressing cells (IC50s=21 μM vs. 1100 μM, respectively.
QBS10072S is 5.5 times more potent at suppressing viability in high LAT1 expressing cells (EC50 = 1.0 μM) vs. non-induced cells (EC50 = 5.5 μM), which had low, endogenous levels of LAT1 expression.
QBS10072S induces dose-dependent viability loss on multiple GBM cell lines with EC50 of 12-40 uM.
QBS10072S treatment demonstrates dose-dependent phosphorylation of H2AX in U251 and LN229 GBM cells.
Unlike temozolomide (TMZ), QBS10072S is cytotoxic to cells with both high and low levels of MGMT expression.
QBS10072S (10 mg/kg, IV, once a week for six weeks) significantly inhibits tumor growth and prolongs survival in orthotopic murine models of GBM.
