Hydrophilic Polymers Containing Chiral Nucleic Acid Base Pendants as Polynucleotide Analogs
A survey of our recent work on synthetic polynucleotide analogs is given. Propionic acid and 3-methyl butyric acid derivatives substituted in the 2-position with nucleic acid bases have been used as chiral pendants for attachment to hydrophilic polyamine backbones. Hindered rotation about the amide bonds formed promotes a base-stacked structure as shown by ultraviolet hypochromic effects versus...
متن کاملNucleic acid base analog FRET-pair facilitating detailed structural measurements in nucleic acid containing systems.
We present the first nucleobase analog fluorescence resonance energy transfer (FRET)-pair. The pair consists of tC(O), 1,3-diaza-2-oxophenoxazine, as an energy donor and the newly developed tC(nitro), 7-nitro-1,3-diaza-2-oxophenothiazine, as an energy acceptor. The FRET-pair successfully monitors distances covering up to more than one turn of the DNA duplex. Importantly, we show that the rigid ...

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
Antagonists of Nucleic Acid Derivatives
Inhibition of the growth of Lactobadlus casei with folic acid as the nutrilite is a general property of 2,4-diaminopyrimidines, 2-aminopyrimidines, and condensed systems containing these groupings (1). These compounds comprise a spectrum of inhibitors. At one end lie the simpler diaminopyrimidines which are competitive antagonists of folic acid (1, 2). The center may be represented by 2-aminopu...
متن کامل[Synthesis and evaluation of novel nucleic acid derivatives as bioactive substances].
This review describes the synthesis and evaluation of novel nucleic acid derivatives performed by our research group to date. We developed a new method for the synthesis of 2-alkoxyadenosine analogs via nonaqueous diazotization-dediazoniation reactions. By applying these reactions, we effectively synthesized four types of carbocyclic oxetanocin analogs (2-alkoxy-C.OXT-A). The angiogenic activit...
