  • Adamantane derivatives of AZA-crown ethers and their use in treatment of tumor
    Patent number: 8389505
    Abstract: The invention relates to adamantane diaza-crown ether derivatives and the use of mono and diaza-crown ether adamantine derivatives in treatment, especially in tumor treatment. Adamantane aza-crown ethers were obtained by reaction of the corresponding adamantane derived tosylates or adamantane acid chlorides with mono- and diaza-18-crown-6. The prepared compounds showed moderate (monoaza-18-crown-6) to strong (diaza-18-crown-6) antiproliferative and cytotoxic activity on several tumor cell lines, revealing their potential for inhibiting the growth of other tumor cells.
