Nucleic acid aptamers against proteases.
Proteases are potential or realized therapeutic targets in a wide variety of pathological conditions. Moreover, proteases are classical subjects for studies of enzymatic and regulatory mechanisms. We here review the literature on nucleic acid aptamers selected with proteases as targets. Designing small molecule protease inhibitors of sufficient specificity has proved a daunting task. Aptamers s...
متن کاملMolecular imaging with nucleic acid aptamers.
With many desirable properties such as ease of synthesis, small size, lack of immunogenicity, and versatile chemistry, aptamers represent a class of targeting ligands that possess tremendous potential in molecular imaging applications. Non-invasive imaging of various disease markers with aptamer-based probes has many potential clinical applications such as lesion detection, patient stratificati...
متن کاملNucleic acid aptamers in human viral disease.
Nucleic acid aptamers are short, single-stranded oligonucleotides or their modified analogues which avidly and specifically interact with targeted ligands through their 3-dimensional structure. Aptamers can be selected out of a large combinatorial oligonucleotide library through an in vitro evolution process termed SELEX. Since 1990, a wide variety of aptamers targeted to ligands ranging from s...
متن کاملChemical Modifications of Nucleic Acid Aptamers for Therapeutic Purposes
Nucleic acid aptamers have minimal immunogenicity, high chemical synthesis production, low cost and high chemical stability when compared with antibodies. However, the susceptibility to nuclease degradation, rapid excretion through renal filtration and insufficient binding affinity hindered their development as drug candidates for therapeutic applications. In this review, we will discuss method...
متن کاملNucleic Acid Aptamers: Research Tools in Disease Diagnostics and Therapeutics
Aptamers are short sequences of nucleic acid (DNA or RNA) or peptide molecules which adopt a conformation and bind cognate ligands with high affinity and specificity in a manner akin to antibody-antigen interactions. It has been globally acknowledged that aptamers promise a plethora of diagnostic and therapeutic applications. Although use of nucleic acid aptamers as targeted therapeutics or med...
