Metallocenes as anti-tumor drugs
-
, (2008/06/13)
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 COOCH3, COOC2 H5, H, COOCH2 CH2 OCH2 CH2 OCH3 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 IC50 [M] values.

New alkene liquid crystals 4-[oligo(ethylene oxide)n monomelhylether)carbonyl]phenyl 4-[4(allyloxy)phenyl]benzoate(MBPBEn, n = 1-3), 4′-[oligo(ethylene oxide)n monomethylether)carbonyl]biphenyl4-yl 4-[4-(allyloxy)phenyl]benzoate(MBPBPEn, n = 1-3), (S)-4-[(2-methyl-1-butoxy)carbonyl]phenyl 4-[4-(allyloxy)phenyl]benzoate(MBPBKA), and (S)-4′ -[(2-methyl-1-butoxy)carbonyl]biphenyl-4-yl 4-[4-(allyloxy)phenyl]benzoate(MBPBPKA) were synthesized and characterized using 1H-NMR and elemental analysis methods. The thermal transition temperatures, mesomorphic properties, and mesophase textures of these compounds have been determined by differential scanning calorimetry (DSC), by polarizing optical microscopy, and by X-ray diffraction analysis. The effect of changes in chemical structure on the mesophase properties, mesophase and isotropic transition temperatures, and mesophase textures are discussed.
