The present invention relates to a method of treating cellular proliferative diseases, in particular cancer, which comprises administering a modulator of the activity of the mitotic kinesin KSP, wherein the activity of the KSP modulator is dependent on the presence of microtubules. It is believed that the KSP modulators utilized in the instant method bind to the KSP protein in a previously unreported manner, since the compounds do not bind competitively with respect to either microtubules or ATP, the substrates of KSP. The modulators useful in the instant methods are furthermore not active against the non-microtubule stimulated activity of KSP. Cellular proliferative diseases that may be treated using the method disclosed herein are, for example cancer, hyperplasias, restenosis, cardiac hypertrophy, immune disorders and inflammation.
本发明涉及一种治疗细胞增殖性疾病,特别是癌症的方法,其包括给予丝裂期动力蛋白K
SP活性调节剂,其中K
SP活性调节剂的活性取决于微管的存在。据信,本方法中使用的K
SP调节剂以一种先前未报道的方式结合到K
SP蛋白上,因为这些化合物不与K
SP的底物微管或
ATP竞争地结合。此外,本方法中有用的调节剂对于K
SP的非微管刺激活性也没有活性。可以使用本文所披露的方法治疗的细胞增殖性疾病包括癌症、增生、再狭窄、心肌肥大、免疫失调和炎症等。
