A Unique Mdm2-Binding Mode of the 3-Pyrrolin-2-one- and 2-Furanone-Based Antagonists of the p53-Mdm2 Interaction

The p53 pathway is inactivated in almost all types of cancer by mutations in the p53 encoding gene or overexpression of the p53 negative regulators, Mdm2 and/or Mdmx. Restoration of the p53 function by inhibition of the p53-Mdm2/Mdmx interaction opens up a prospect for a nongenotoxic anticancer therapy. Here, we present the syntheses, activities, and crystal structures of two novel classes of Mdm2-p53 inhibitors that are based on the 3-pyrrolin-2-one and 2-furanone scaffolds. The structures of the complexes formed by these inhibitors and Mdm2 reveal the dimeric protein molecular organization that has not been observed in the small-molecule/Mdm2 complexes described until now. In particular, the 6-chloroindole group does not occupy the usual Trp-23 pocket of Mdm2 but instead is engaged in dimerization. This entirely unique binding mode of the compounds opens new possibilities for optimization of the Mdm2 p53 interaction inhibitors.

Selective 1,4-Addition of Organolithiums to Maleate Monoesters with Application for a Short Efficient Route to Azaindanones

The ability of maleate half-ester salts to serve as electrophilic partners in 1,4-conjugate addition reactions with control of regioselectivity has previously been explored in only a limited context with soft nucleophiles. We have demonstrated that benzylic anions of picolines, as well as enolates of ketones, esters, and nitriles, react with lithium 4-( tert -butoxy)-4-oxobutenoate in a completely regioselective manner. This new method was applied to an expedient two-step process for preparing a key azaindanone intermediate for the clinical-candidate drug MK-8666.

Reactions with pyrrolidine-2,4-diones, part 4*: Synthesis of some 3-substituted 1,5-diphenylpyrrolidine-2,4-diones as potential antimicrobial, anti-HIV-1 and antineoplastic agents

The condensation of 1,5-dipheiiylpyrrolidine-2,4-dione (1) with ethyl orthoformate yielded 3-ethoxymethylene-1,5-diphenylpyrrolidinc-2,4-dione (2). Reaction of the latter with hydrazine hydrate, secondary amines 7a-c or urea afforded the corresponding 3-substituted aminomethylene-1,5-diphenylpyrrolidene-2,4-diones 3, 8a-c or 9. On the other hand, condensation of 3 With veratraldehyde (5a) yielded 3-[(3,4-dimethoxybenzylidene)hydrazinomethylene]-1,5-diphenylpyrrolidine-24-dione (6). Whereas, cyclization of 9 with the reactive malonate ester 11 produced 3-[(5-butyl-4-hydroxy-2,6dioxo- 1,2,3,6- tetralhydropyrimidin-1-yl) methylene]-1,5-diphenylpyrrolidine-2,4-dione (12). The condensation of some selected aromatic aldehydes 5a-c and addition of morpholine (7c) or piperidine (7d) to some of the resulting 3-arylidene,1,5-diphenylpyrrolidine-2,4-diones 13b, e gave the respective 3-substituted methyl-4-hydroxy-1,5-diphenyl-Delta (3)-pyrrolin-2-ones 14a-c. Selected members of the new series were screened for their in vitro antimicrobial, anti-HIV-1 and antineoplastic activities. Two compounds 14a, b showed pronounced inhibitory activities against Gram-positive bacteria; whereas, in the in vitro anti-HIV-1 screening, only one compound Be displayed a moderate activity. However, in the antineoplastic screening protocol, the tested compounds were devoid of activity.

Palladium-catalyzed tandem reaction of epoxynitriles with arylboronic acids in aqueous medium: divergent synthesis of furans and pyrroles

The efficient selective synthesis of furans and pyrroles has been realized by means of a palladium-catalyzed tandem addition/ring-opening/cyclization reaction of 2-(3-aryloxiran-2-yl)acetonitriles with arylboronic acids in aqueous medium for the first time. The chemoselectivity of this transformation can be predominantly governed by the steric effects of arylboronic acids: the reactions of 2-(3-aryloxiran-2-yl)acetonitriles with the less sterically hindered arylboronic acids provided furans as the sole products, while those of the sterically bulky arylboronic acids delivered pyrroles selectively. The O-18-labelled experiments revealed that the oxygen atom of furans is derived from water, and a plausible mechanism for this selective synthesis of furans and pyrroles was proposed.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates. Interested yet? Read on for other articles about 229625-50-7. Name: Di-tert-butyl chloromethyl phosphate.

Inhibitory effect of 3,4-diaryl-3-pyrrolin-2-one derivatives on cyclooxygenase 1 and 2 in murine peritoneal macrophages

AIM: To develop a whole-cell assay based on murine peritoneal macrophages and evaluate the inhibitory effect of candidate compounds on cyclooxygenase-1 (COX-1) and COX-2. METHODS: Macrophages were stimulated with calcimycin or hpopolysaccharide (LPS) for various periods. Their abilities to convert endogenous arachidonic acid to 6-keto-PGF(1alpha) or PGE(2) were examined by radioimmunoassay (RIA). RNA level of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and COX-1/2 was detected by reverse transcription polymerase chain reaction (RT-PCR) using specific primers. RESULTS: Rofecoxib selectively inhibited LPS-induced, COX-2-derived PGE(2) synthesis with an IC50 value of (4.7+/-0.5) nmol/L compared with maximum inhibitory ratio of 17.3 % for the inhibition of calcimycin induced, COX-1-derived 6-keto-PGF(1alpha) synthesis. Indomethacin exhibited dual inhibitory effects on COX-1 and COX-2 with IC50 of (4.7+/-1.1) nmol/L and (7.1+/-1.2) nmol/L, respectively. Two series of 17 compounds were tested. Most of compounds in series 11 showed comparable inhibitory activities to rofecoxib on COX-2. The relative position of the sulfonylphenyl group to the lactam carbonyl group has important effects on COX-2 inhibitory activity. CONCLUSION: The established whole cell assay is appropriate for drug-design oriented in vitro assay. 3,4-Diaryl-3-pyrrolin-2-one derivatives were proved to be prospective new type of COX-2 selective inhibitors.

A theoretical investigation of iron-catalyzed selective hydrogenation of nitriles to secondary imines

The mechanism of the transition metal iron complex [(iPr-PNP)Fe(H)Br(CO)] catalyzed reaction of selective hydrogenation of nitriles to secondary imines has been investigated with the M06-2X function. The results indicate that the reaction involves two basic processes: (i) A catalyzed p-bromobenzonitrile to benzaldimine and primary amine transformation; (ii) condensation of benzaldimine with a primary amine to afford secondary imine. The calculated barrier of transition metal-catalyzed condensation reaction of benzaldimine with a primary amine, 30.6 kcal/mol, indicates that the condensation reaction is feasible under experiment conditions. The theoretical results provide a deeper understanding of the mechanism and fully explain the experimental facts.
