MDL-27048
MDL-27048, a tubulin inhibitor, binds competitively, reversibly to the Colchicine (HY-16569)-binding site on tubulin heterodimers. MDL-27048 inhibits microtubule assembly, induces slow depolymerization of preassembled microtubules, disrupts microtubule polymerization-depolymerization dynamics, and disrupts cytoplasmic microtubule networks. MDL-27048 exerts growth inhibitory effects on human cancer cells, induces mitotic arrest, and does not disrupt actin filaments at microtubule-depolymerizing concentrations. MDL-27048 can be used for the research of malignant tumors.

MDL-27048 (0.4-20 μM; 40 min, 25 °C) binds reversibly to one site per purified porcine brain tubulin heterodimer with an apparent equilibrium constant of (2.1-3.5) × 106 M-1, and its binding site overlaps with the podophyllotoxin/colchicine-binding site[2].
MDL-27048 (0.5-20 μM; 30-96 min) inhibits in vitro assembly of purified porcine brain tubulin into microtubules with an IC50 of 1 μM at 1 mg/mL tubulin, induces slow depolymerization of pre-assembled microtubules, and its inhibitory effect is reversible with taxol[2].
MDL-27048 (0.2-10 μM; 10 min-4 h, monitored 2-30 min after wash-off) induces concentration- and time-dependent reversible depolymerization of PtK2 cell cytoplasmic microtubules, with maximal depolymerization achieved at 2-5 μM for 3 h, and complete repolymerization within 15-30 min after drug removal[2].
MDL-27048 (0.05-1 μM; 3-27 h) induces mitotic arrest in SV40-3T3 cells, with significant arrest at 0.2 μM and a mitotic index increase to 12.7% at 1 μM after 9 h, causing accumulation of cells with doubled DNA content[2].

Cell Line:PtK2 cells
-
Concentration:0.2 μM; 0.5 μM; 0.8 μM; 2 μM; 5 μM
-
Incubation Time:3 h
-
Result:Induced concentration-dependent depolymerization of cytoplasmic microtubules: 0.2 μM caused undulating peripheral microtubules; 0.5-1 μM caused partial depolymerization; 2-5 μM caused maximal depolymerization, leaving only a few drug-resistant microtubules per cell, with no effect on actin filaments.

Concentration:10 μM
-
Incubation Time:10 min; 20 min; 80 min; 180 min
-
Result:Caused full depolymerization within 3 h.
-
Cell Line:SV40-3T3 cells
-
Concentration:1 μM
-
Incubation Time:3 h; 6 h; 9 h; 27 h
-
Result:Increased the mitotic index from 1% (control) to 2.7% at 3 h, 10.2% at 6 h, and 12.7% at 9 h at 1 μM.
Caused a marked shift to higher DNA content in 1 μM-treated cells at 6-9 h, indicating accumulation of cells that completed S phase but failed to progress through mitosis.
