A major advantage of DNA as a carrier is that no chemical synthesis or manipulations are needed to obtain DNA-drug complex. The efficacy of the DNA-drug complex depends on stability in the bloodstream, endocytic behavior of normal and tumor cells, presence of extra-cellular deoxyribonuclease activity in the tumor tissues, and capillary barriers that separate normal and tumor cells from the bloodstream. 

The degradation and formation of nonabsorbable drug complexes in the intestinal lumen is the third factor, in addition to dissolution and permeability, which could affect fraction absorption. Limitations of bioavailability due to these factors seem to be less frequent compared with the two other main factors. Regulatory guidelines for BCS-based biowaivers still ask for in vitro studies of luminal degradation in relevant test media, whereas specific binding studies are not required [17].

Other immunosuppressive drugs under investigation were FK506 and rapamycin and its affinity to human FKBP12 (27). The hFKBP12-drug complexes were separated from unbound protein and detected by hyphenation to mass spectrometry. 

One important property that determines entry to the brain from the systemic circulation is molecular weight. Compounds with molecular weights of about 60,000 and above tend to remain within the circulatory system. Furthermore, the portion of an administered drug that is bound to plasma proteins is unavailable for distribution to the brain (as well as to other tissues and organs), in part because of the high molecular weight of the plasma protein-drug complex. 

Human immunodeficiency virus (HIV) is a single-stranded RNA retrovirus that causes acquired immunodeficiency syndrome (AIDS), a condition in which individuals are at increased risk for developing certain infections and malignancies. The virus is found in two major forms HIV-1, the most prevalent worldwide, and HIV-2, the most common in western Africa. More than 22 million people have died of HIV infection, and 40 million are believed to be infected worldwide. AIDS epidemics threaten populations in sub-Saharan Africa, Southeast Asia, Central and South America, and Russia. In the United States about 450,000 deaths have occurred and another 900,000 people are estimated to carry the virus. Although the development of new drugs, complex multidrug regimens, and behavioral modification have done much to combat the spread of HIV in-...
