Cobinamides as Structural Probes in B12‐Biosynthesis: Synthesis and Spectroscopic Analysis of Isomers of Coα,Coβ‐Dicyanocobinamide
Authors: Murtaza Shahzad , Kräutler Bernhard 
Published: April 2008

AbstractVitamin B12 and its coenzyme forms are cobalamins (i.e., cobamides, ‘complete’ with a 5,6‐dimethylbenzimidazole nucleotide base), in which the particular corrinoid moiety of the cobinamides is conjugated to α‐ribazole‐3′‐phosphate via a phosphate‐diester group. Aside of being provided with their particular reactivity, required for their functions as organometallic cofactors in B12‐dependent enzymes, the cobalamins also depend upon their specific three‐dimensional buildup, to be able to adapt the unique constitution of ‘base‐on’ corrinoids by intramolecular Co‐coordination of the nucleotide base. We report rational partial syntheses and detailed spectral analyses of three close cobinamide isomers in their Coα,Coβ‐dicyano forms: of 13‐epicobinamide (also called neocobinamide), of 176(S)‐epicobinamide, and of 176‐isocobinamide. Neocobinamide was obtained under acidic conditions as a degradation product of vitamin B12. 176(S)‐Epicobinamide and 176‐isocobinamide were prepared by condensation of cobyric acid with (2S)‐1‐aminopropan‐2‐ol and with 3‐aminopropan‐1‐ol, respectively. Natural cobinamide represents the corrinoid nucleus produced by proper microbial biosynthesis (as intermediate for the further assembly of the ‘complete’ corrinoid cofactors) or is required in some microorganisms, such as Escherichia coli, as an exogenously supplied unit for further biosynthetic buildup. The three compounds may thus be of use as structural probes for the biosynthetic capacity and tolerance in microorganisms, and (some of them) may serve as substrates as well, for further biosynthetic ‘completion’ of corrinoid cofactors or their analogues.
Carboxamides Combining Favorable Olfactory Properties with Insect Repellency
Authors: Gaudin Jean‐Marc , Lander Thierry , Nikolaenko Olga 
Published: April 2008

AbstractBy a simple methodology, we have synthesized 68 carboxamides, with structural analogy to the most efficient mosquitoes repellent DEET (N,N‐diethyl‐m‐toluamide, 9). Eight of them have very promising olfactory profiles. In addition, 34 carboxamides have been tested for their repellency properties against three breeds of cockroach; six of them are excellent in this domain. Two of these, the 2‐ethyl‐N‐isopropyl‐N‐methylbutanamide and N,N‐diallyl‐2‐ethylbutanamide combine both the positive aspects, and are thus very good candidates for use in functional perfumery, and more particularly in home‐care formulations.
Synthesis of Novel Pyrrolo[3,4‐d]pyrazole‐dicarboxylic Acids and Evaluation of Their Interaction with Glutamate Receptors
Authors: Conti Paola , di Ventimiglia Samuele Joppolo , Pinto Andrea , Tamborini Lucia , Menniti Frank S. , Lazzaro John T. , De Micheli Carlo 
Published: April 2008

AbstractChiral pyrazoline amino acids (3aR,4S,6aR)‐1a and (3aR,4S,6aR)‐1b, and (3aS,6S,6aS)‐2a and (3aS,6S,6aS)‐2b, which are conformationally constrained analogues of glutamic and homoglutamic acid, respectively, were prepared via a strategy based on the 1,3‐dipolar cycloaddition of a nitrile imine to methyl N‐Boc‐3,4‐didehydro‐(S)‐prolinate. The new ‘amino acids’ were tested for activity at ionotropic glutamate receptors. Solely the derivative (3aR,4S,6aR)‐1a, which is structurally related to the previously described 4,5‐dihydroisoxazole analogue (S)‐CIP‐A, turned out to be a potent and selective agonist for the AMPA receptors. The biological activity is due to the interaction with the orthosteric glutamate binding site.
