Description

Anticancer agent 98 (compound 12k) is a microtubule/tubulin-polymerization inhibitor (Kd=16.9 μM). Anticancer agent 98 exerts antiproliferative potency against tumor cells, exhibits anti-angiogenesis effect in vitro. Anticancer agent 98 exhibits good human and mouse liver microsomes stability with both t1/2>300 min[1].

In Vitro

Anticancer agent 98 inhibits cancer proliferation among melanoma, breast cancer, and pancreatic cancer with IC50s ranging from 0.6-3 nM[1].
Anticancer agent 98 (300 nM, 1 μM, or 3 μM; 2 h) increases β-tubulin adduct in PC-3 cells dose-dependently[1].
Anticancer agent 98 (3.125, 6.25, 12.5, 25, and 50 μM) has high-binding affinity to tubulin proteins with Kd value of 16.9 μM by SPR spectroscopy assay[1].
Anticancer agent 98 (10 μM, 50 μM; 0-60 min) strongly inhibits tubulin polymerization during 60 min[1].
Anticancer agent 98 (100 nM; 4 h) has antiproliferative and anti-angiogenesis effect on COS-7 cells in vitro[1].

In Vivo

Anticancer agent 98 (2.5 mg/kg; i.v.; twice per week for 2 weeks) is well tolerated with no significant weight loss in PC3/TxR xenograft tumors in male NSG mice. Anticancer agent 98 also significantly attenuates the progression of prostate cancer tumors, relative to the Paclitaxel (HY-B0015; 10 mg/kg, once weekly) and control groups[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
