MODIFIED DRUGS FOR USE IN LIPOSOMAL NANOPARTICLES

Drag derivatives are provided herein which are suitable for loading into liposomal nanoparticle carriers. In some preferred aspects, the derivatives comprise a poorly water-soluble drag derivatized with a weak-base moiety that facilitates active loading of the drag 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 drag to the inner monolayer of the liposomal membrane. Advantageously, LN formulations of the drag derivatives exhibit improved solubility, reduced toxicity, enhanced efficacy, and/or other benefits relative to the corresponding free drags.

13C CP MAS NMR, FTIR, X-ray diffraction and PM3 studies of some N-(ω-carboxyalkyl)morpholine hydrohalides

N-(ω-carboxyalkyl)morpholine hydrochlorides, OC4H8N(CH2)nCOOH·HCI, n = 1-5, were obtained and analyzed by 13C cross polarization (CP) magic angle spinning (MAS) NMR, FTIR and PM3 calculations. The structure of N-(3-carboxy-propyl)morpholine hydrochloride (n = 3) has been solved by X-ray diffraction method at 100 K and refined to the R = 0.031. The crystals are monoclinic, space group P21/c, a = 14.307(3), b = 9.879(2), c = 7.166(1) A?, β = 93.20(3)°, V = 1011.3(3) A?3, Z = 4. In this compound the nitrogen atom is protonated and two molecules form a centrosymmetric dimer, connected by two N+-H···Cl- (3.095(1) A?) and two O-H···Cl- (3.003(1) A?) hydrogen bonds. 13C CP MAS NMR spectra, contrary to the solution, showed non-equivalence of the ring carbon atoms. The PM3 calculations predict a molecular dimer without proton transfer for an HCl complex, while for an HBr complex an ion pairs with proton transfer, and reproduces correctly the conformation of both dimers but overestimates H-bond distances. Shielding constants calculated from the PM3 geometry of ion pairs gave a linear correlation with the 13C chemical shifts in solids.
