Isomeric N-(Nitrenophenyl)nitrenobenzamides. Comparison of the Energy Differences between Their Singlet and Quintet States Obtained Computationally and Experimentally
摘要:
The sign and magnitude of the intramolecular magnetic coupling between the two triplet nitrene units through the benzanilide chromophore have beep studied by temperature dependence of their EPR fine structures; The results that the interactions are ferromagnetic in the m,p' and m',p isomers and antiferromagnetic in the p,p' and m,m' isomers were corroborated by semiempirical CI calculations.

The targeting of one mRNA in the transcriptome requires small molecules that bind with substantial affinity and specificity. As such, compounds with specificity for individual RNA secondary structural motifs could be useful for targeting RNA. Described herein is the synthesis of a combinatorial library of 105 dimers of deoxystreptamine and the subsequent identification of compounds with specificity for specific RNA hairpin loop sizes, including tetraloops and octaloops. Such compounds will be useful for the perturbation of RNA function in vivo.
