  • Derivatives of (Z)-1,2-diphenylethene
    Patent number: 10065935
    Abstract: The present invention relates to the new chemical compounds containing (Z)-1,2-diphenylethene moiety in the structures, particularly the new derivatives of cis-stilbene, the new derivatives of 4,5-diphenyl-1,3-oxazole, the new derivatives of 1-methyl-4,5-diphenyl-1H-imidazole and pharmaceutically acceptable salts thereof. The invention relates also to the application of aforementioned compounds as a microtubule-interfering agents (MIAs). The new derivatives, because of their potential antimitotic and antiangio-genic activity, can be used as ingredients in the preparations used in the treatment of cancer.
