Synthesis of 6-membered cyclic carbonates from 1,3-diols and low CO2 pressure: A novel mild strategy to replace phosgene reagents

Low pressure carbon dioxide is used as the carbonation agent in a simple, safe and efficient procedure for the synthesis of 6-membered cyclic carbonates from 1,3-diols. Using readily available reagents and proceeding at room temperature, this route offers a novel mild alternative to phosgene derivatives.

Chicoric acid analogues as HIV-1 integrase inhibitors

The present study was undertaken to examine structural features of L- chicoric acid (3) which are important for potency against purified HIV-1 integrase and for reported cytoprotective effects in cell-based systems. Through a progressive series of analogues, it was shown that enantiomeric D- chicoric acid (4) retains inhibitory potency against purified integrase equal to its L-counterpart and further that removal of either one or both carboxylic functionalities results in essentially no loss of inhibitory potency. Additionally, while two caffeoyl moleties are required, attachment of caffeoyl groups to the central linking structure can be achieved via amide or mixed amide/ester linkages. More remarkable is the finding that blockage of the catechol functionality through conversion to tetraacetate esters results in almost no loss of potency, contingent on the presence of at least one carboxyl group on the central linker. Taken as a whole, the work has resulted in the identification of new integrase inhibitors which may be regarded as bis-caffeoyl derivatives of glycidic acid and amino acids such as serine and beta-aminoalanine. The present study also examined the reported ability of chicoric acid to exert cytoprotective effects in HIV-infected cells. It was demonstrated in target and Cell-based assays that the chicotic acids do not significantly inhibit other targets associated with HIV-1 replication, including reverse transcription, protease function, NCp7 zinc finger function, or replication of virus from latently infected cells. In CEM cells, for both the parent chicoric acid and selected analogues, antiviral activity was observable under specific assay conditions and with high dependence on the multiplicity of viral infection. However, against HIV, 1- and HIV-2-infected MT-4 cells, the chicoric acids and their tetraacetylated esters exhibited antiviral activity (50% effective concentration (EC50) ranging from 1.7 to 20 muM and 50% inhibitory concentration (IC50) ranging from 40 to 60 muM).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 19132-06-0, you can also check out more blogs about19132-06-0

(R)- and (S)-Tricyclo<6.4.0.04,9>dodecane

The title compounds 6 have been prepared from rac. 1,4-dihydroxytricyclo<6.4.0.04,9>dodecane-7,10-dione (1).In this way the diastereomeric thioacetals 3 made from (-)-(R,R)-2,3-butanedithiol (2) could be separated by chromatography as well as was transformed into the pure enantiomers of 6. (S)-configuration was predicted for (-)-1 from its positive CD at 300 nm.This could be proved by X-ray diffraction analysis with abnormal dispersion of the diastereoisomer of 3 with the smaller RF value, which yields (-)-1 on hydrolysis.The relatively high rotation = 30 of6is explained by steric twisting.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about19132-06-0.Related Products of 19132-06-0

Enantioselective oxidation of diols by secondary alcohol dehydrogenase from Geotrichum sp. WF9101

Geotrichum sp. WF9101 could degrade (S)-(+)-1,2-propanediol, (S)-(+)- 1,3-butanediol, and (2S,4S)-(+)-2,4-pentanediol, but not the corresponding enantiomers. An NAD+-linked secondary alcohol dehydrogenase purified from the strain showed the same enantioselective oxidations towards these diols. This enzyme is proposed to be useful for the preparation of (R)-(-)-diols from the racemates of these diols.

Inhibition of topoisomerase II by ICRF-193, the meso isomer of 2,3-bis(2,6-dioxopiperazin-4-yl)butane: Critical dependence on 2,3-butanediyl linker absolute configuration

The bis(2,6-dioxopiperazine)s are a structurally and mechanistically unique class of topoisomerase II inhibitors that do not bind DNA and that do not stabilize topoisomerase II-DNA strand passing intermediates (“cleavable complexes”). The most effective topoisomerase II inhibitor in the bis(2,6-dioxopiperazine) series is ICRF-193 (meso or S*, R* isomer), with a meso 2,3-butanediyl linker connecting the dioxopiperazine rings. The two enantiomeric diastereomers, (R,R) and (S,S), of ICRF-193 possessing the two optically active 2,3-butanediyl linkers have been prepared from their respective optically pure 2,4-diaminobutanes via 2,3-diaminobutane-N,N,N?,N?-tetraacetic acid, esterification, and imide formation. Both in vivo and in vitro assays for catalytic inhibition of topoisomerase II were employed to show that the (S,S)-and (R,R)-isomers are almost inactive as topoisomerase II inhibitors. The data indicate that the meso stereochemistry of the alkanediyl linker is crucial for activity and provides additional evidence that the cytotoxicity of the bis(2,6-dioxopiperazine)s is due to their ability to inhibit topoisomerase II.
