WS-691
WS-691 is an orally active, selective ABCB1 modulator. WS-691 selectively stabilizes ABCB1 via direct binding to ABCB1. WS-691 inhibits the efflux function of ABCB1 and activates ABCB1 ATPase activity. WS-691 elevates intracellular Paclitaxel (HY-B0015) levels and reduces the required dose of Paclitaxel in cancer cells overexpressing ABCB1. WS-691 increases the sensitivity of colon cancer cells to Paclitaxel.

WS-691 (20 μM) reduces the IC50 of paclitaxel from 4.23 μM to 0.022 μM in paclitaxel-resistant cancer cells with ABCB1 overexpression, and exhibits no cytotoxicity when used alone[1].
WS-691 (0-40 μM; 20 min) stimulates the ATPase activity of ABCB1 to 2.5-fold of the basal activity[2].

Animal Model:BALB/c nude (male, 5-6 weeks old, 15-17 g, subcutaneous inoculation of SW620/Ad300 cells)[2]
-
Dosage:20 mg/kg (single agent); 20 mg/kg (in combination with paclitaxel 5 mg/kg)
-
Administration:i.g.; daily; 21 days;
-
Result:Showed little effect on tumor growth compared to vehicle group when used as a single agent.
Significantly reduced tumor volume and tumor weight compared to paclitaxel alone, paclitaxel plus verapamil, or vehicle group when combined with paclitaxel.
Induced more tumor cell death (evident as nuclear pyknosis in HE staining) and higher levels of tumor cell apoptosis (evident as bright green staining in TUNEL assays) compared to single-agent and control groups when combined with paclitaxel.
Caused no obvious liver injury when used alone or in combination with paclitaxel.
