Influence of Drug-to-Lipid Ratio on Drug Release Properties and Liposome Integrity in Liposomal Doxorubicin Formulations

Recent studies have shown that the release properties of vincristine encapsulated in large unilamellar vesicles (LUV) can be regulated by varying the drug-to-lipid (D/L) ratio. In this work it is shown that the drug-to-lipid ratio technique for regulating drug release also applies to doxorubicin encapsulated in LUV. In particular it is shown that the half-times (T_1/2) for doxorubicin release from distearoylphosphatidylcholine (DSPC)/cholesterol LUV in vitro can be increased more than six-fold by increasing the D/L ratio from 0.05 (wt/wt) to 0.39 (wt/wt). This behavior is consistent with the behavior expected for drugs that precipitate following accumulation into liposomes. It is shown that the release properties of ciprofloxacin—a drug that does not precipitate following accumulation into LUV—are not affected by the D/L ratio. It is also shown that the crystalline intravesicular doxorubicin precipitates observed as the D/L ratio is raised from 0.05 to 0.46 adopt increasingly unusual morphologies. Linear crystals are observed at lower D/L values, however triangular and rectangular variations are observed as the D/L ratio is increased, and induce considerable distortion in vesicle morphology. It is noted that trapping efficiency following uptake of external doxorubicin into LUV is reduced from nearly 100% at a D/L ratio of 0.05 (wt/wt) to less than 70% at an (initial) D/L ratio of 0.8 (wt/wt). It is suggested that this arises, at least in part, from membrane-disrupting effects of internal drug crystals as they increase in size.     

Mutagenesis of the putative nucleotide-binding domains of the multidrug resistance associated protein (MRP). Analysis of the effect of these mutations on MRP mediated drug resistance and transport

Studies were conducted to examine the functional role of the nucleotide-binding domains of MRP in drug resistance and drug transport in isolated membrane vesicles. In vivo studies were conducted by preparing stable transfectants of HeLa cells with wild-type MRP cDNA or MRP cDNAs which had been mutated at certain nucleotide binding domains (NBD). Stable transfectants producing equivalent amounts of the MRP encoded protein P190 were used in this study. The results demonstrated that deletions in the C-motif of NBD1 or the A-motif of NBD2 have a pronounced effect in reducing resistance levels to chemotherapeutic agents. Certain single-site mutations in lysines in these same motifs also reduce IC₅₀ values. It has also been observed that mutation of the MRP NBDs results in an increase in drug accumulation and a reduction in drug efflux. Additional studies have been carried out in which recombinant baculovirus containing either wild-type MRP or MRP containing mutated NBDs was prepared and used to infect SF21 insect cells. Using this system we have analyzed the effects of these mutations on in vitro transport of leukotriene C₄ (LTC₄) 17 β-estradiol 17 (β-D-glucuronide)(E₂17βG) and daunomycin in membrane vesicles prepared from baculovirus infected cells. The results demonstrate that deletions and site-specific mutations in MRP NBDs greatly reduce the ATP dependent transport of all three substrates. The results of these studies conducted both in vivo and in vitro demonstrate that the NBDs of MRP function in a cooperative manner and are critical for the transport activity of the MRP encoded protein P190. These studies also identify specific lysines in NBD1 and NBD2 which are important for optimal MRP activity. This revised version was published online in August 2006 with corrections to the Cover Date.     

The Effects of pH and Intraliposomal Buffer Strength on the Rate of Liposome Content Release and Intracellular Drug Delivery

Targeted liposomal drug formulations may enter cells by receptor-mediated endocytosis and then traffick by membrane flow into acidic intracellular compartments. In order to understand the impact of these intracellular pH changes on liposomal drug unloading, the effect of pH on the release from folate-targeted liposomes of three model compounds with distinct pH dependencies was examined. 5(6)-carboxyfluorescein, which titrates from its anionic to uncharged form following internalization by KB cells, displays strong endocytosis-dependent release, since only its uncharged (endosomal) form is membrane permeable. Endocytosis-triggered unloading of drugs of this sort is enhanced by encapsulating the drug in a weak buffer at neutral pH, so that acidification of the intraliposomal compartment following cellular uptake can occur rapidly. Sulforhodamine B, in contrast, retains both anionic and cationic charges at endosomal pH (~pH 5), and consequently, escapes the endosomes only very slowly. Doxorubicin, which is commonly loaded into liposomes in its membrane-impermeable (cationic) form using an acidic buffer, still displays endocytosis-triggered unloading, since sufficient uncharged doxorubicin remains at endosomal pHs to allow rapid re-equilibration of the drug according to the new proton gradient across the membrane. In this case, when the extraliposomal [H⁺] increases 250-fold from 4 × 10^–8 M (pH 7.4, outside the cell) to 10^–5 M (pH 5, inside the endosome), the ratio of doxorubicin inside to outside the liposome must decrease by a factor of 250. Therefore, the collapse of the transliposomal pH gradient indirectly drives an efflux of the drug molecule from the liposome. Since a change in intraliposomal pH is not required to unload drugs of this type, the intraliposomal compartment can be buffered strongly at acidic pH to prevent premature release of the drug outside the cell. In summary, pH triggered release of liposome-encapsulated drugs can be achieved both with drugs that increase as well as decrease their membrane permeabilities upon acidification, as long as the intraliposomal buffer strength and pH is rationally selected.
