- Dynamic combinatorial libraries of hydrazone-linked pseudo-peptides: Dependence of diversity on building block structure and chirality
-
Expanding on our earlier building block architecture [(MeO) 2CH-Linker-Pro-X-NHNH2 where X = Phe, Cha], we have produced a series of new pseudo-dipeptides [(MeO)2CH-Linker-Pro-X- NHNH2 where X = Val, Leu, Ile, A

- Expeditious amide-forming reactions using thiol esters
-
The reaction of a 2-pyridylthiol ester with a dimethylaluminum amide leads to the rapid formation of the corresponding amide. The tolylthiol esters can be activated with silver trifluoroacetate and coupled even with poorly reactive amino compounds. (C) 20

- Rapid, one-pot synthesis of urethane-protected tripeptides
-
Urethane-protected tripeptides are synthesized in solution, without isolation of purification of intermediates, using urethane-protected N-carboxyanhydrides as coupling reagents and hydrogenation for removal of N-protection.

- Peptidyl α-Ketoheterocyclic Inhibitors of Human Neutrophil Elastase. 2. Effect of Varying the Heterocyclic Ring on in Vitro Potency
-
A series of peptidyl α-ketoheterocycles were synthesized and evaluated for their in vitro inhibition of human neutrophil elastase (HNE).Several heterocycles, including oxazoline and benzoxazole, afforded extremely potent inhibitors of HNE (1p-r) with nano

- KINETICS OF THE ALKALINE HYDROLYSIS OF SEVERAL N-BENZYLOXYCARBONYLDIPEPTIDE METHYL AND ETHYL ESTERS
-
The reaction rates of the alkaline hydrolysis of synthesized N-protected dipeptide methyl and ethyl esters were studied systematically.From the kinetic data the energies of activation, the pre-exponential factors and the reference values at 40 deg C were calculated.The rate of hydrolysis shows to be strongly dependent on the C-terminal amino acid in the sequence Gly >> Ala/Met/Phe > Leu >> Val/Pro.Surprisingly the N-terminal amino acid also exerts an effect, but in a different sequence.N-Terminal Phe in particular shows a relative accelerating effect.Remarkable is the significantly faster ester hydrolysis of glycine containing dipeptide ethyl esters in ethanol/water compared to the corresponding methyl esters in methanol/water.

- Peptide Synthesis with Benzo- and Naphthosultones
-
6-Nitro- and 6,8-dinitronaphth-1,2-oxathiole S,S-dioxides (7b and 7c) have been prepared from the parent naphthosultone 7a and compared with 5-nitrobenz-3H-1,2-oxathiole S,S-dioxide (1b) as coupling reagents for peptide synthesis.Nucleophilic attack of a carboxylate salt on these strained five-membered sultones leads to activated esters 3 and 9 which rapidly react with amines (except in the case of 9c).The rate constant for the formation of ester 9b is higher than that of 3b.Amides or peptides are formed in slightly better yields with the naphthosultone 7b than with the benzosultone 1b.The naphthosultones are also preferred over the benzosultones from the point of view of amount of 5(4H)-oxazolone formation from N-benzoyl amino acids and the degree of racemization.However the rate of alkaline hydrolysis of 7b is slower than that of 1b.All these results may be rationalized by a better intramolecular acyl transfer reaction in the more rigid mixed anhydride intermediate 8b.There is no dependence on in the rate equation for aminolysis of esters 3b and 9b by benzylamine in THF, acetonitrile, or DMF and the aminolysis is probably anchimerically assisted by a neighbouring S=O group.Esters 3b are more selective acylating agents for primary amino groups in the presence of secondary ones than esters 9b and this observation is exploited in a synthesis of maytenine by selective acylation of spermidine.

- RATES OF PEPTIDE FORMATION INVOLVING IMINO ACID RESIDUES
-
The determination of the rates for peptide coupling in tetrahydrofuran between Z-Aaa-OPcp (Aaa = Ala, (NMe)Ala, Pro, Thz, Pip and (S)Pip) and H-Bbb-OMe (Bbb = (NMe)Ala, Pro, Thz, Pip and (S)Pip) allowed us to evaluate the relative reactivities between these members, either as active components or as amino components.The reactivity of Pro (either as the active species or the amino component) equals that of (NMe)Ala.The reactivity of Pip and (S)Pip as imino components is low while the activation energy is raised by an amount that roughly equals the energy increment needed for bringing the carboxylate grouping from the equatorial to the axial position The reactivities of these six-membered residues are also appreciably low when being the active components during peptide coupling.The presence of a ring-sulfur atom at γ-position of nitrogen additionally decreases the rate for peptidation, especially if (S)Pip is the imino component.
