Whereas stereochemical purity in drugs has become the standard for small molecules, stereoisomeric mixtures containing as many as a half million components persist in antisense oligonucleotide (ASO) therapeutics because it has been feasible neither to separate the individual stereoisomers, nor to synthesize stereochemically pure ASOs. Here we report the(More)
Carbamate linked prolyl nucleic acids are obtained in high yield and purity under mild conditions in solution and solid phase. p-Nitrophenylchloroformate is used as the activating reagent for alcohol. Homooligomers of PrCNA do not bind to DNA. The introduction of this modification in PNA sequences destabilizes the triplexes, inspite of enhancement in the(More)
Cloud storage is a model of data storage in which the digital data is stored in logical pools. It allows users to store their data in a remote server to get rid of expensive local storage and management costs and then access data of interest anytime anywhere. We propose an enhanced dynamic proof of retrievability scheme supporting public audit ability and(More)
To delineate the binding preferences of stereochemically divergent pyrrolidine PNAs, synthesis of all four diastreomeric monomers of I and the systematic complexation studies of the resultant PNAs with complementary DNA/RNA is essential. We herein report the synthesis of trans-L/D-2-(tert-butoxycarbonyl-aminomethyl)-4-(thymin-1-yl) pyrrolidin-1-yl acetic(More)
Cis-D-2-hydroxy-4-thymin-1-yl-pyrrolidine propionic acid unit is used to make PNA-DNA dimer block that is incorporated in DNA sequences at selected positions. Since the amide linkage is shorter than phosphodiester linkage, insertion of an extra atom in the backbone with amide linkage seems to be better accommodated for internucleotide(More)
Stress is a broad term, generally used in negative connotation and is described as the cumulative detrimental effect of a variety of factors on the health and performance of animals. Heat stress occurs in animals when there is an imbalance between heat production within the body and its dissipation. Heat stress is one of the wide varieties of factors which(More)
