[Image] ACTIVITY : Cytostatic. MECHANISM OF ACTION : Mitotic motor protein inhibitor; Mitotic motor protein regulator; Mitotic motor protein modulator. In a test, 3,4-tetrahydropyrano-fused 6-tert. butyl-2-(3-thienyl)-1,2,3,4-tetrahydroquinoline derivative (Ia) inhibited the cell cycle of HCT cells, typically in presence of 0.4 mu M the cells were in 7% G1, 7% S and 86% G2/M phase, compared with 36% G1, 43% S and 21% G2/M in the absence of (Ia).
