  • Patent number: 7005124
    Abstract: Antineoplastic dendritic polymer conjugates which are useful drug delivery systems for carrying antineoplastic agents to malignant tumors are prepared by obtaining a dendritic polymer having functional groups which are accessible to an antineoplastic agent capable of interacting with the functional groups, and contacting the dendritic polymer with the antineoplastic agent. The preferred platin-based analogues of the antineoplastic agents conjugated to the dendritic polymer may be administered intravenously, orally, parentally, subcutaneously, intramuscularly, intraarterially or topically to an animal having a malignant tumor in an amount which is effective to inhibit growth of the malignant tumor. The antineoplastic dendritic polymer conjugates exhibit high drug efficiency, high drug carrying capacity, good water solubility, good stability on storage, reduced toxicity, and improved anti-tumor activity in vivo.

  • Publication number: 20060039891
    Abstract: Antineoplastic dendritic polymer conjugates which are useful drug delivery systems for carrying antineoplastic agents to malignant tumors are prepared. The antineoplastic agent is encapsulated within the dendritic polymer using an ionic charge shunt mechanism, whereby, the antineoplastic agent interacts with the anionic functional groups on the surface of the dendritic polymer allowing the antineoplastic agent to be uptaken by the dendritic polymer through an association with the functional groups of the interior of the dendritic polymer. The antineoplastic dendritic polymer conjugates may be administered intravenously, orally, parentally, subcutaneously, intraarterially or topically to an animal having a malignant tumor in an amount which is effective to inhibit growth of the malignant tumor. The antineoplastic dendritic polymer conjugates exhibit high drug efficiency, high drug carrying capacity, good water solubility, good stability on storage, and reduced toxicity.

  • Patent number: 6790437
    Abstract: Dendritic polymer conjugates which are useful drug delivery systems for carrying platinum containing anti-tumor agents to malignant tumors are prepared by obtaining a dendritic polymer having functional groups which are accessible to a platinum containing compound capable of interacting with the functional groups, contacting the dendritic polymer with the platinum containing compound, and reacting the dendritic polymer with the platinum containing compound. The dendritic polymer platinates may be administered intravenously, orally, parentally, subcutaneously or topically to an animal having a malignant tumor in an amount which is effective to inhibit growth of the malignant tumor. The dendritic polymer platinates exhibit high drug efficiency, high drug carrying capacity, good water solubility, good stability on storage, reduced toxicity, and improved anti-tumor activity in vivo.

  • Publication number: 20020048598
    Abstract: A system comprising a branched polymeric structure which provides a structural support for a mono-layer, bi-layer or multi-layered lipid coating. The branched polymeric structure may include dendrimers, arborol or, star polymers, hyperbranched structures, and cascade polymer systems. A method of producing the system is also disclosed. The system is essentially comprised of a structurally supportive core overlaid with a lipid portion. The supportive core may also interact with a biologically active molecule. The core may provide a matrix-like structure, which functions both as a structural support for the lipid portion and a site for interaction with the lipid portion.
