Resistance to β-lactam antibiotics is mediated primarily by enzymes that hydrolytically inactivate the drugs by one of two mechanisms: serine nucleophilic attack or metal-dependent activation of a water molecule. Serine β-lactamases are countered in the c

Selective cleavage of carbamate protecting groups from aziridines with otera's catalyst

, p. 411 - 415 (2014/04/03)
Otera's distannoxane catalyst was found to promote the cleavage of carbamate groups from N-protected aziridines. This method enables the chemoselective cleavage of an aziridinyl N-carbobenzyloxy (Cbz) group in the presence of other N-Cbz groups. The selec
Studies on the synthesis of orthogonally protected azalanthionines, and of routes towards β-methyl azalanthionines, by ring opening of N-activated aziridine-2-carboxylates

Orthogonally protected azalanthionines were successfully synthesised by the ring-opening of N-activated aziridine-2-carboxylates with protected diaminopropanoic acids (DAPs). The required DAPs were also prepared by ring-opening of N-activated aziridine-2-carboxylates with para- methoxybenzylamine, but it was found that the choice of aziridine protecting groups dictated both the success of the reaction as well as the regioselectivity of the isolated products. Attempts to extend the methodology to the preparation of the more sterically demanding β-methyl azalanthionines have, so far, been unsuccessful.

The preparation of tryptophan derivatives through the Lewis acid promoted substitution of aziridine carboxylates with indole was found to be accompanied by a ring-expansion reaction to generate an oxazolidinone byproduct. The ratio of tryptophan to oxazol

Orthogonally protected azalanthionines (lanazanines, 4-azadiaminopimelic acids or β-aminoalaninoalanines) have been synthesised in good yields by the ring-opening of N-protected aziridine 2-carboxylates with suitably protected diaminopropanoic acids (DAPs
Proteomic searches comparing two (R)-lacosamide affinity baits: An electrophilic arylisothiocyanate and a photoactivated arylazide group

We have advanced a novel strategy to search for lacosamide ((R)-1) targets in the brain proteome where protein binding is expected to be modest. Our approach used lacosamide agents containing "affinity bait" (AB) and "chemical reporter" (CR) units. The affinity bait moiety is designed to irreversibly react with the target, and the CR group permits protein detection and capture. In this study, we report the preparation and evaluation of (R)-N-(4-azido)benzyl 2-acetamido-3-(prop-2-ynyloxy)propionamide ((R)-3) and show that this compound exhibits potent anticonvulsant activities in the MES seizure model in rodents. We compared the utility of (R)-3 with its isostere, (R)-N-(4-isothiocyanato)benzyl 2-acetamido-3-(prop-2-ynyloxy)propionamide ((R)-2), in proteomic studies designed to identify potential (R)-1 targets. We showed that despite the two-fold improved anticonvulsant activity of (R)-3 compared with (R)-2, (R)-2 was superior in revealing potential binding targets in the mouse brain soluble proteome. The difference in these agents' utility has been attributed to the reactivity of the affinity baits (i.e., (R)-2: aryl isothiocyanate moiety; (R)-3: photoactivated aryl azide intermediates) in the irreversible protein modification step, and we conclude that this factor is a critical determinant of successful target detection where ligand (drug) binding is modest. The utility of (R)-2 and (R)-3 in in situ proteome studies is explored.
