The objective of this work was to synthesize cyclic prodrug 2 derived from the parent RGD peptidomimetic 1 and to evaluate its chemical and enzymatic stabilities and antithrombic activity. Cyclic prodrug 2 was formed to improve the cell membrane permeation of RGD peptidomimetic 1 by transiently masking the unfavorable physicochemical properties of compound 1. Cyclic prodrug 2 was synthesized by linking the amino and carboxylic acid groups of parent 1 via the (acyloxy)alkoxy promoiety. The prodrug-to-drug conversion of cyclic prodrug 2 was evaluated in isolated esterase and human plasma in the absence and presence of the esterase inhibitor paraoxon. The rate of hydrolysis of cyclic prodrug 2 was significantly faster in plasma (t1/2 = 33.5 ± 0.6 min) than in PBS (t1/2 = 314 ± 11 min). Cyclic prodrug 2 was converted by esterase to the parent compound 1 and this conversion was inhibited by an esterase inhibitor, paraoxon. The IC50 (4 muM) of cyclic prodrug 2 was higher than the IC50 (1.9 muM) of parent drug 1. The antithrombic activity of cyclic prodrug 2 depends on the incubation time in platelet-rich plasma; the activity increases with incubation time, suggesting that the prodrug-to-drug conversion is time-dependent and mediated by esterase. Cyclic prodrug 2 was more stable under acidic and neutral conditions than under basic conditions, suggesting that handling and formulation of this prodrug should be undertaken under acidic conditions.

The present invention relates to the novel pyrazolodiazepine compounds which potently inhibit the activity of transglutaminase in a dose dependent manner. Accordingly, it has been confirmed that the inventive compounds show potent inhibiting effect on the hyper-activated transglutaminase when the transglutaminase is over-expressed. Therefore the compounds can be useful in treating or preventing the disease caused by increased activation of transglutaminase.

Metallosalen are privileged complexes that have found important applications in catalysis. In addition, their luminescent properties have also been studied and used for sensing and biological applications. Salen metal complexes can be efficient photosensitizers, but they can also participate to electron transfer processes. Indeed, we have found that commercially available [Al(Salen)Cl] is an efficient photoredox catalyst for the synergistic stereoselective reaction of alkyl aldehydes with different bromo ketones and malonates to give the corresponding enantioenriched alpha-alkylated derivatives. The reaction was performed in the presence of a MacMillan catalyst. [Al(Salen)Cl] is able to replace ruthenium complexes, showing that also aluminum complexes can be used in promoting photoredox catalytic reactions.

(Chemical Equation Presented) Enantiomeric discrimination is observed in the 1H and 13C NMR spectra of piperidines and piperazines in the presence of (-)-(18-crown-6)-2,3,11,12-tetracarboxylic acid. The amines are protonated by the carboxylic acid groups of the crown ether to produce the corresponding ammonium and carboxylate ions. Association of the ammonium ion with the crown ether likely involves two hydrogen bonds with the crown ether oxygen atoms and an ion pair with the carboxylate anion. Methyl, hydroxymethyl, phenyl, carboxyl, pyridyl, and cyclohexyl substituent groups alpha to the nitrogen atom do not inhibit binding of the ammonium ion to the crown ether. The NMR spectra of piperidines with the stereogenic center alpha or beta to the nitrogen atom exhibit substantial enantiomeric discrimination. Dibasic substrates such as the piperizines are likely converted to their diprotonated form in the presence of the crown ether, and both nitrogen atoms appear to associate with the crown ether moiety.

(Chemical Equation Presented) Trifluoromethyl-substituted 1-amino-1-azapenta-1,4-dien-3-ones 4, which are accessible in good yield from pyruvates 1 in a three-step procedure, undergo a cascade reaction involving inter alia two electrocyclizations upon treatment with a large excess of trifluoromethanesulfonic acid to give novel dihydrospiroindenepyrazole 5a-o and dihydroindenodiazepine 6a-j. We interpret this sequence of reactions on the basis of quantum chemical calculations as a dicationic cyclization of a pentadien-1-one (“superelectrophilic solvation”), where one of the double bonds is part of an aromatic ring and a subsequent rearrangement to form an (monocationic) iminium ion, which either cyclizes to give five-membered spiro ring systems (compounds 5) or tricyclic dihydroindenodiazepine derivatives 6. Hueckel- and Moebius-type transition states of the electrocyclization reactions are discussed considering the results of NICS calculations. One 1-amino-1-penta-1,4-dien-3-one 4 and several dihydrospiroindenepyrazoles 5 and dihydroindenodiazepines 6 could be characterized by X-ray diffraction.

We examine the relationship between covalent structure and conformational propensity among a series of beta-amino acid tetramers. These experiments focus on the hairpin folding motif. Among conventional peptides, the minimum increment of beta-sheet secondary structure is a ‘beta-hairpin,’ in which two strands are connected via a short loop. The present studies are aimed at optimizing hairpin stability among beta-peptides. Previous work from our laboratory has identified optimal substitution patterns for residues that form strands in an antiparallel beta-peptide sheet (Krauthauser et al. J. Am. Chem. Soc. 1997, 119, 11719), and we have shown that a dinipecotic acid segment can promote sheet-type interactions between attached strand residues (Chung et al. J. Am. Chem. Soc. 1998, 120, 10555). Here we compare all four possible configurations of the dinipecotic acid segment, (R,S), (S,R), (R,R) and (S,S), for the ability to induce sheet formation with a constant set of enantiomerically pure strand residues. We show that both heterochiral dinipecotic acid segments promote hairpin formation, although one is distinctly superior. Neither of the homochiral dinipecotic acid supports hairpin folding. When the strand residues are beta-alanine (achiral), the heterochiral dinipecotic acid segment is again superior to the homochiral segment, but we find a difference between hairpin conformations in solution and in the solid state.
