Patent number: 10730999Abstract: The present invention generally relates to macromolecules of dendrimer-drug conjugates. In particular, the invention relates to macromolecules comprising a pharmaceutically active agent, such as a protein or peptide, attached to a core of a dendrimer derived from branched building units, such as lysine or lysine analogues. The invention also relates to the synthesis of the dendrimers and macromolecules, and the use of such macromolecules, particularly in therapeutic applications, and pharmaceutical compositions comprising them.Type: GrantFiled: June 5, 2015Date of Patent: August 4, 2020Assignee: Starpharma Pty LtdInventors: David James Owen, Pauline Stanislawski, Michael Giannis, Oliver Bernhard

Patent number: 9585387Abstract: PEHAM dendrimers of the formula: Specific PEHAM dendrimers are used in a formulation with an active agent for agricultural purposes. In particular, the PEHAM dendrimers may be used for increasing the efficacy of the active agent in various ways, such as by improving solubility of the active agent in the formulation, by improving adhesion and penetration of the active agent to plant surfaces, or by improving the water-fastness of the active agent to the plant or seed. The PEHAM dendrimers may also increase the efficacy of the active agent by increasing soil penetration of the active agent to reach the plant roots or under soil parts, by reducing soil adhesion of the active agent to reach the plant roots or under soil parts, or by reducing enzymatic degradation of the active agent by the plant or seed or microorganisms in the soil.Type: GrantFiled: February 16, 2015Date of Patent: March 7, 2017Assignee: STARPHARMA PTY LTDInventors: Ryan T. Hayes, David James Owen, Abhay Singh Chauhan, Veera Reddy Pulgam, Harsh Vardhan
