Patent number: 8324410Abstract: Drug derivatives are provided herein which are suitable for loading into liposomal nanoparticle carriers. In some preferred aspects, the derivatives comprise a poorly water-soluble drug derivatized with a weak-base moiety that facilitates active loading of the drug through a LN transmembrane pH or ion gradient into the aqueous interior of the LN. The weak-base moiety can optionally comprise a lipophilic domain that facilitates active loading of the drug to the inner monolayer of the liposomal membrane. Advantageously, LN formulations of the drug derivatives exhibit improved solubility, reduced toxicity, enhanced efficacy, and/or other benefits relative to the corresponding free drugs.Type: GrantFiled: May 8, 2012Date of Patent: December 4, 2012Assignee: The University of British ColumbiaInventors: Pieter Cullis, Marcel Bally, Marco Ciufolini, Norbert Maurer, Igor Jigaltsev

Patent number: 8314261Abstract: The present invention relates to a process for the preparation of synthetic taxanes, which protects C(7)-OH with lanthanon compounds. Its advantages are simple process and firm & reliable binding. Moreover, no C(7)-acylated taxanes are produced in the subsequent steps, and hydrolysis of C(2?)-ester groups in acylated products becomes readily controllable. In the process for the preparation of synthetic taxanes, tetrahydrofuran is used in the present invention as a medium for acylation, which not only achieves the same effects as pyridine, but also avoids odor, so as to solve the problem regarding the extremely high requirements for the place of production. The present invention can be used for the preparation of not only semi-synthetic taxane using natural taxanes as raw material, but also full-synthetic taxane.Type: GrantFiled: January 17, 2005Date of Patent: November 20, 2012Assignee: Guilin Huiang Biochemistry Pharmaceutical Co.

Publication number: 20120252968Abstract: Copoly(imide oxetane) materials are disclosed that can exhibit a low surface energy while possessing the mechanical, thermal, chemical and optical properties associated with polyimides. The copoly(imide oxetane)s are prepared using a minor amount of fluorinated oxetane-derived oligomer with sufficient fluorine-containing segments of the copoly(imide oxetane)s that migrate to the exterior surface of the polymeric material to yield low surface energies. Thus the coatings and articles of manufacture made with the copoly(imide oxetane)s of this invention are characterized as having an anisotropic fluorine composition. The low surface energies can be achieved with very low content of fluorinated oxetane-derived oligomer. The copolymers of this invention can enhance the viability of polyimides for many applications and may be acceptable where homopolyimide materials have been unacceptable.Type: ApplicationFiled: November 1, 2011Publication date: October 4, 2012Applicant: U.S.A. as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Christopher J.
