More Info
HMN-176 is a potential new cancer therapeutic known to retard the proliferation of tumor cell lines. This compound inhibits meiotic spindle assembly in surf clam oocytes and delays satisfaction of the spindle assembly checkpoint in human somatic cells by inducing the formation of short and/or multipolar spindles. HMN-176 does not affect centrosome assembly, nuclear envelope breakdown, or other aspects of meiotic or mitotic progression, nor does it affect the kinetics of Spisula or mammalian microtubule (MT) assembly in vitro. Notably, HMN-176 inhibits the formation of centrosome-nucleated MTs (i.e., asters) in Spisula oocytes and oocyte extracts, as well as from isolated Spisula or mammalian centrosomes in vitro. Together, these results reveal that HMN-176 is a first-in-class anticentrosome drug that inhibits proliferation, at least in part, by disrupting centrosome-mediated MT assembly during mitosis. (source: Mol Cancer Ther. 2009 Mar;8(3):592-601. ).
Biological target:
HMN-176 is a stilbene derivative which inhibits mitosis, interfering with polo-like kinase-1 (plk1), without significant effect on tubulin polymerization.
In vitro activity:
As summarized in Table 1, HMN-176 greatly increased the duration of mitosis in both cell lines. This delay in satisfying the spindle assembly checkpoint (SAC) indicates HMN-176 negatively impacts some aspect of spindle MT assembly and/or behavior.

In vivo activity:
However, aster formation, spindle assembly, and polar body extrusion were completely inhibited in HMN-176 treated cells. Together, these data suggest HMN-176 prevents spindle assembly and meiosis in Spisula oocytes by inhibiting centrosome-dependent MT nucleation, i.e., aster formation.
