MS105
Based on 1 Customer Validation
MS105 (YX39-105) is an orally active and selective protein tyrosine kinase 6 (PTK6) (BRK) PROTAC degrader. MS105 recruits VHL E3 ligase via a VHL ligand moiety, promotes PTK6 ubiquitination and proteasomal degradation, inhibits the proliferation and migration of breast cancer cells, and induces apoptosis. MS105 shows potential for use in breast cancer research.

MS105 binds to PTK6 with a Kd of 730 nM in a cell-free competitive displacement assay[1].
MS105 (1 μM) inhibits the in vitro activity of PTK6 and 5 additional kinases by >65% in a cell-free KINOMEScan assay[1].
MS105 (0.07-1.25 μM; 24 h) potently reduces PTK6 protein levels in T47D human ER+ breast cancer cells[1].
MS105 (0.003-1.25 μM; 4-72 h) potently degrades PTK6 in MDA-MB-231/LM2-4 human triple negative breast cancer cells with a DC50 of 21 nM and Dmax of 84%, with detectable degradation as early as 8 hours and persistence for up to 72 hours[1].
MS105 (0.07-0.3 μM) degrades PTK6 in MDA-MB-231/LM2-4 human triple negative breast cancer cells via a proteasome- and VHL-dependent mechanism, as pre-treatment with proteasome, VHL, or NEDD8-activating enzyme inhibitors abrogates PTK6 degradation[1].
MS105 (0.16-0.3 μM) requires direct binding to PTK6 to induce degradation in MDA-MB-231/LM2-4 human triple negative breast cancer cells, as pre-treatment with the high-affinity PTK6 inhibitor P21d blocks PTK6 degradation[1].
MS105 (dose range; 72 h) potently inhibits viability of multiple human breast cancer cell lines (triple negative, ER+, Her2+), with EC50 values ranging from 0.47 to 0.93 μM[1].
MS105 (1 μM; up to 12 days) degrades PTK6 but does not inhibit cell viability or growth in MCF10A human non-transformed mammary epithelial cells or CAPAN-2 human pancreatic cancer cells[1].
MS105 (0.3-1 μM; 24 h) induces apoptosis of MDA-MB-231/LM2-4 human triple negative breast cancer cells and T47D human ER+ breast cancer cells, as evidenced by increased caspase 3/7 activity, cleaved PARP, Bim upregulation, and p38 activation[1].
MS105 (0.6-1 μM; 24 h pre-treatment + 12 h migration) potently inhibits migration of MDA-MB-231 human triple negative breast cancer cells[1].
