摘要:
A process for preparing biodegradable microparticles comprising a biodegradable polymeric binder and a biologically active agent. A first phase, comprising the active agent and the polymer, and a second phase are combined under the influence of mixing means to form an emulsion and microparticles are isolated from the emulsion. A blend of at least two substantially non-toxic solvents, free of halogenated hydrocarbons, is used to dissolve or disperse the agent and dissolve the polymer.
摘要:
The present invention provides a method for preparing microparticles having a selected polymer molecular weight. The hold time and temperature of a solution containing a nucleophilic compound and a polymer having a starting molecular weight are controlled in order to control the molecular weight of the polymer in the finished microparticle product. In this manner, a selected polymer molecular weight in the finished microparticle product can be achieved from a variety of starting material molecular weights.

Agents, such as bradykinin agonists, increase the transport of pharmaceutical or diagnostic substances that are initially in the bloodstream of a host animal into the interstitial spaces of non-central nervous system solid tumors that may reside in these hosts. A particularly efficacious agent is CereportTM.
摘要:
L'invention concerne des procédés et des compositions pour la détection et/ou l'inhibition ciblée d'une protéine intracellulaire dans une cellule en mettant en contact la cellule avec un anticorps cationisé qui réagit de manière spécifique avec la protéine intracellulaire. Un exemple d'une protéine intracellulaire qui peut être inhibée de cette manière est la protéine Tat qui est codée par le virus HIV-1.
