Described herein are two series (twelve compounds each) of very closely related guanidinium‐based receptors and their ability to catalyze hydrolytic cleavage of a unique RNA substrate – oligo‐dT flanked trans‐Activation Responsive region of the HIV‐1 mRNA, TAR RNA. The significant difference in activities of otherwise very similar compounds is discussed, and direct and indirect evidences supporting
A highly efficientsynthesis of 2‐arylamino‐2‐imidazolines and 2‐aminobenzimidazoles from aminoimino‐methanesulfonic acidderivatives is described. The method is simple and practical, generating imidazoline and benzimidazoline derivatives in excellent isolated yields.
A photo- and dioxygen-enabled intermolecular radical Csp3-Nsp2 cross-coupling between guanidines and perfluoroalkyl iodides has been developed. N2-Perfluoroalkacylguanidines, which are of biological importance, were obtained under mild conditions via Nsp2-perfluoroalkylation and subsequent hydrolysis. The role of dioxygen in the reaction system was tentatively elucidated; it was supposed to act as
Targeting quorum sensing by designing azoline derivatives to inhibit the N-hexanoyl homoserine lactone-receptor CviR: Synthesis as well as biological and theoretical evaluations
resistance, we investigated the interruption of quorumsensing mediated by non-classical bioisosteres of the N-hexanoyl homoserine lactone with an azoline core. For this purpose, a set of selected 2-substituted azolines was synthesized, establishing the basis for a new protocol to synthesize 2-amino imidazolines. The synthesized compounds were evaluated as inhibitors of violacein production in Chromobacterium
