Structure-activity of tetrad-forming oligonucleotides as a potent anti-HIV therapeutic drug.
Recently, we have described the design and characterization of oligonucleotides containing only G and T bases, i.e. T30695 and T30177, that are potent inhibitors of human immunodeficiency virus type 1 (HIV-1) replication in culture (Jing, N., Rando, R. F., Pommier, Y., and Hogan, M. E. (1997) Biochemistry 36, 12498-12505). To understand that observation and to rationalize the generally high the...
متن کاملG-Quadruplex Forming Oligonucleotides as Anti-HIV Agents.
Though a variety of different non-canonical nucleic acids conformations have been recognized, G-quadruplex structures are probably the structural motifs most commonly found within known oligonucleotide-based aptamers. This could be ascribed to several factors, as their large conformational diversity, marked responsiveness of their folding/unfolding processes to external stimuli, high structural...
متن کاملDiscovery of novel anti-HIV active G-quadruplex-forming oligonucleotides.
A series of d((5')TGGGAG(3')) sequences, 5'-conjugated with a variety of aromatic groups through phosphodiester linkages, were synthesized, showing CD spectra diagnostic of parallel-stranded, tetramolecular G-quadruplex structures. When tested for anti-HIV-1 and HIV-2 activity, potent inhibition of HIV-1 infection in CEM cell cultures was found, associated with high selectivity index values. Su...
متن کاملTetra-end-linked oligonucleotides forming DNA G-quadruplexes: a new class of aptamers showing anti-HIV activity.
The biophysical and biological properties of unprecedented anti-HIV aptamers are presented. The most active aptamer (1L) shows a significant affinity to the HIV protein gp120.
متن کاملA new insight into viral proteins as Immunomodulatory therapeutic agents. KSHV vOX2 a homolog of human CD200 as a potent anti-inflammatory protein
The physiologic function of the immune system is defense against infectious microbes and internal tumour cells, Therefore, need to have precise modulatory mechanisms to maintain the body homeostasis. The mammalian cellular CD200 (OX2)/CD200R interaction is one of such modulatory mechanisms in which myeloid and lymphoid cells are regulated. CD200 and CD200R molecules are membrane proteins that t...
