So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Bhosle, Govind S.; Fernandes, Moneesha researched the compound: cis-4-Aminocyclohexane carboxylic acid( cas:3685-23-2 ).Product Details of 3685-23-2.They published the article 《(R-X-R)4-motif peptides containing conformationally constrained cyclohexane-derived spacers: Effect on cellular uptake》 about this compound( cas:3685-23-2 ) in ChemMedChem. Keywords: cell penetrating peptide derivative preparation role cellular uptake; (R-X-R)-motif; cell-penetrating peptides; cellular uptake; protease stability. We’ll tell you more about this compound (cas:3685-23-2).
Arg residue-rich peptides having the (R-X-R)n motif are among the most effective cell-penetrating peptides (CPPs). Here, we report a several-fold increase in the efficacy of such CPPs if the linear flexible spacer (-X-) in the (R-X-R) motif is replaced by constrained cyclic 1,4-substituted-cyclohexane-derived spacers. Internalization of these oligomers in mammalian cell lines was found to be an energy-dependent process. Incorporation of these constrained, non-proteinogenic amino acid spacers in the CPPs was shown to enhance their proteolytic stability.
