The invention relates to novel titanocene derivatives possessing chemotherapeutic activity and method for their preparation. These compounds possess two cyclopentadiene rings linked to titanium as a central atom and bound covalently to two phenoxy groups which possess a substituent R selected from the group consisting of COOCH.sub.3, COOC.sub.2 H.sub.5, H, COOCH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OCH.sub.3 and are free from amino, nitro, chloride and fluoride groups. The novel compounds represent a compromise between the main properties for an antitumor agent, i.e., electrophilicity and stability, being water soluble. Cytotoxicity measurements of these compounds showed significant growth inhibition properties, expressed in terms of IC.sub.50 [M] values.
本发明涉及具有化疗活性的新型钛环戊二烯衍生物及其制备方法。这些化合物具有两个环戊二烯环与钛作为中心原子相连,并以共价键结合到两个具有取代基R的苯氧基团上,所述取代基R来自于COOCH.sub.3,COOC.sub.2 H.sub.5,H,COOCH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OCH.sub.3的群组,且不含氨基,硝基,氯和氟化物基团。这些新化合物代表了一种抗肿瘤药物的主要特性,即亲电性和稳定性之间的折衷,同时具有水溶性。这些化合物的细胞毒性测量表明,它们具有显著的生长抑制特性,以IC.sub.50 [M]值表示。
