Provided herein are therapeutic acrylate compounds useful as medical adhesives, comprising a therapeutic agent covalently linked to a methacrylate or cyanoacrylate moiety. Adhesive compositions and kits, such as liquid sutures and bone cement also are provided along with uses for the compositions.
A stabilized semi-solid delivery vehicle contains a polyorthoester and an excipient, and a pharmaceutical composition contains an active agent, optionally a stabilizing agent, and the delivery vehicle. The pharmaceutical composition may be a topical, syringable, or injectable formulation; and is suitable for local delivery of the active agent. Methods of treatment are also disclosed.

The present invention relates to nitric oxide releasing prodrugs of known drugs or therapeutic agents which are represented herein as compounds of formula (I) wherein the drugs or therapeutic agents contain one or more functional groups independently selected from a carboxylic acid, an amino, a hydroxyl and a sulfhydryl group. The invention also relates to processes for the preparation of the nitric oxide releasing prodrugs (the compounds of formula (I)), to pharmaceutical compositions containing them and to methods of using the prodrugs.
The subject matter of the present invention relates to the use of an optionally branched linear terpene having at most one C═C unsaturation for the production of conjugates provided with self-assembly properties, as well as a self-assembly agent of formula (I):
X(-Spacer-Y-Terpene)
p
(I)
in which:
“Terpene” is linear, optionally branched, having at most one C═C unsaturation;
“Y” is a bond or a molecular fragment with a biodegradable bond;
“Spacer” is a bond or a fragment comprising at least one carbon atom;
“X” is a molecular fragment comprising at least one biodegradable bond;
“p” ranges between 0.1 and 4; and
the “-Spacer-Y-” group optionally can be a bond,
as well as the conjugate resulting from the combination of the self-assembly agent of formula (I) with an active molecule MA.

PEG-POE, PEG-POE-PEG, and POE-PEG-POE block copolymers have both hydrophilic and hydrophobic blocks. They form micelles in aqueous solution, making them suitable for encapsulation or solubilization of hydrophobic or water-insoluble materials; and they also form bioerodible matrices for the sustained release of active agents, especially when the POE block(s) contain at least one unit containing an &agr;-hydroxy acid.
