The present application provides methods for preparing soluble lipidated ligand agents comprising a ligand entity and a lipid entity, and in some embodiments, provides relevant parameters of each of these components, thereby enabling appropriate selection of components to assemble active agents for any given target of interest.
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.

14-Dinitrodehydroabietic acid (12,14-dinitroDHAA), a chiral acid obtained by the nitration of opticaldehydroabieticacid (DHAA), was successfully employed as resolving agent. The resolution of racemic bupivacaine by ultrasonic-assisted diastereomericcrystallization in ethanol was investigated. The results indicated that ultrasonic-assist can well facilitate resolution of (R,S)-bupivacaine and a higher

Medical articles including a hydrophilic water-swellable hydrogel and methods of using and making the articles are provided. The hydrogel may include a crosslinked mixture of a biocompatible polymer and a protein, such as polyethylene glycol and a soy protein. The hydrogel may further include an agent, such as diazolidinyl urea and iodopropynyl butylcarbamate, dispersed within the hydrophilic water-swellable hydrogel.
