Therapeutic applications of the cell-penetrating HIV-1 Tat peptide.
Over the past decades, many new therapeutic approaches have been developed for several conditions, including neurodegenerative diseases. However, efficient biodistribution and delivery at biological target sites are hampered by the presence of cell and tissue barriers, and a clinical therapy is prevented by the requirement of invasive administration routes. Candidate drug conjugation to cell-pe...
متن کاملCharacterization of a Cell‐Penetrating Peptide with Potential Anticancer Activity
Cell-penetrating peptides (CPPs) are still an interesting and viable alternative for drug delivery applications. CPPs contain considerably high amounts of positively charged amino acids, imparting them with cationic character. Tumor cells are characterized by an enhanced anionic nature of their membrane surface, a property that could be used by CPPs to target these cells. We recently identified...
متن کاملBroad-spectrum anti-human immunodeficiency virus (HIV) potential of a peptide HIV type 1 entry inhibitor.
The AIDS epidemic continues to spread at an alarming rate worldwide, especially in developing countries. One approach to solving this problem is the generation of anti-human immunodeficiency virus (HIV) compounds with inhibition spectra broad enough to include globally prevailing forms of the virus. We have examined the HIV type 1 (HIV-1) envelope specificity of a recently identified entry inhi...
متن کاملCell-penetrating peptide conjugates of peptide nucleic acids (PNA) as inhibitors of HIV-1 Tat-dependent trans-activation in cells
The trans-activation response (TAR) RNA stem-loop that occurs at the 5' end of HIV RNA transcripts is an important antiviral target and is the site of interaction of the HIV-1 Tat protein together with host cellular factors. Oligonucleotides and their analogues targeted to TAR are potential antiviral candidates. We have investigated a range of cell penetrating peptide (CPP) conjugates of a 16me...
متن کاملCombined effect of a peptide-morpholino oligonucleotide conjugate and a cell-penetrating peptide as an antibiotic.
A cell-penetrating peptide (CPP)-morpholino oligonucleotide (MO) conjugate (PMO) that has an antibiotic effect in culture had some contaminating CPPs in earlier preparations. The mixed conjugate had gene-specific and gene-nonspecific effects. An improved purification procedure separates the PMO from the free CPP and MO. The gene-specific effects are a result of the PMO, and the nonspecific effe...
