  • Patent number: 11414443
    Abstract: The present invention relates to 1-acyl-lysophosphatidyl derivatives of general formula I; in which R is C4 to C30 aliphatic hydrocarbyl chain, R1 is selected from H or C1 to C10 alkyl, preferably C1 to C6 alkyl, R2 is selected from H, C10 to C30 acyl or C1 to C10 alkyl, preferably C1 to C6 alkyl, and R3, when present, is selected from H or C1 to C10 alkyl, preferably C1 to C6 alkyl. These derivatives are intended for the treatment of cancer, in particular melanoma, hepatocarcinoma or GIT carcinomas.

  • Publication number: 20200078379
    Abstract: The deferoxamine derivatives of general formula I and pharmaceutically acceptable salts thereof, at least one of R1 and R2 is a substituent of formula II. The novel derivatives are particularly suitable as medicaments, preferably for the treatment of cancer. Pharmaceutical preparations of compounds of formula I and a metal, preferably gallium, are also provided resulting in even more active medicaments or contrast agents. Combinations with other agents, resulting in synergistic effects are provided.

  • Patent number: 9896466
    Abstract: The subject of the invention are new mitochondrially targeted E/Z isomers of aliphatic triphenylphosphonium derivatives of tamoxifen where the aliphatic chain is alkyl or alkenyl, and their corresponding tertiary amine salts and/or their mixture (MitoTAX). Alkyl triphenylphosphonium derivatives of tamoxifen have the general formula (I), where n=8 to 12 and where Z is selected from the group of organic salts or inorganic salts. Alkenyl triphenylphosphonium derivatives of tamoxifen have the general formula IA, where n=6 to 10 and where Z has the above mentioned meaning. These compounds are applicable for the treatment of neoplastic disease, especially those with high HER2 protein levels. The drug for the treatment of neoplastic diseases according to the invention contains at least one E/Z isomer of aliphatic triphenylphosphonium derivatives of tamoxifen of the general formula (I) and/or IA or their corresponding salts of tertiary amine.
