摘要:Polyglutamates are well known to be highly biocompatible, biodegradable and multifunctional polymers, which have been already used as building blocks in polymer drug conjugates and polymeric micelles. Those systems have been applied to various medical applications ranging from therapy to molecular imaging. Furthermore a polyglutamic acid (PGA) paclitaxel conjugate has already entered clinical studies (Opaxioâ„¢ PGA-PTX conjugate currently in phase III of Clinical trials). n In this context, a synthetic pathway to a plethora functional polyglutamates (homopolymers, block-co-polymers, tribocks) with well-defined structure, adjustable molecular weight (Mw) and low dispersity (D=Mw/Mn<1.2) applying the ring opening polymerization (ROP) of N-carboxyanhydrides (NCA) has been developed. Additionally, the acid moieties of the polyglutamates can be activated with 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium (DMTMM) and various functionalities can be easily introduced by “post-polymerization modificationâ€? yielding a set orthogonal reactive attachment sides. The reactive moieties, such as azides, maleimides, thiols, akynes (linear or cyclic) offer the opportunity of specific conjugation of the drugs, targeting moieties or markers. Besides introducing reactive groups the functionalization strategy was also used for PEGylation of PGA reducing charge induced interactions and therefore pharmacological properties, such as blood circulation time may be adjusted. n In summary, a tool kit of various polyglutamates has been developed enabling the synthesis of a variety of polymer drug conjugates or polymer based imaging agents. The functional polymeric precursors developed will allow us to functionalize and therefore adjust the polymer properties to a desired aplication.

摘要:Disclosed herein are methods for synthesizing 1-(acyloxy)-alkyl prodrug derivatives of drugs through oxidation of 1-acyl-alkyl derivatives of drugs under anhydrous reaction conditions. The methods typically proceed stereospecifically, in high yield, do not require the use of activated intermediates and/or toxic compounds and are readily amenable to scale-up.
