Understanding the Cis-Trans Amide Bond Isomerization of N,N′-Diacylhydrazines to Develop Guidelines for A Priori Prediction of Their Most Stable Solution Conformers

Jugal Kishore Rai Deka et al.

Summary: N,N'-diacylhydrazines are a class of small molecules widely used in chemistry and biology. They have eight isomeric forms due to the unique structure of two amide groups connected by an N-N single bond. The stability and conformation of these molecules are influenced by the substituents on nitrogen atoms. A guideline for predicting the most stable conformers of N,N'-diacylhydrazines based on substituents (R1-R4) is provided.

Deciphering the Backbone Noncovalent Interactions that Stabilize Polyproline II Conformation and Reduce cis Proline Abundance in Polyproline Tracts

Biswajit Sahariah et al.

Summary: The amino acid Proline has a higher tendency to adopt cis amide geometry, and polyproline tracts can form either PPI or PPII helical conformation. Recent studies have shown a reduced presence of cis amide geometry in the inner Pro residues of a poly-Pro tract. The backbone noncovalent interactions play a crucial role in stabilizing trans Pro-amide geometry and preferring a PPII helical conformation.

Evidence of an nN(amide) → π*Ar Interaction in N-Alkyl-N,N′-diacylhydrazines

Jugal Kishore Rai Deka et al.

Summary: 1,2-Dibenzoyl-1-tert-butylhydrazine and related N-alkyl-N,N'-diacylhydrazines are environmentally friendly insect growth regulators. The interactions mediated by a hydrazide amide nitrogen atom play a crucial role in stabilizing their biologically active trans-cis rotameric conformations, as supported by spectroscopic and computational studies.
