In vivo selective modulation of tissue glutathione in a rat mammary carcinoma model

Glutathione (GSH) is known to play a role in cellular sensitivity to some chemotherapeutic agents and to radiation. Depletion of cellular GSH has been demonstrated to result in enhanced toxicity of these drugs, and this approach is being explored in the clinic as a form of biochemical modulation, using the drug buthionine sulfoximine (BSO). The fact that some drug-resistant cell lines have increased glutathione levels, and that enhancing GSH concentrations in animal tissues protects against a variety of xenobiotic agents, suggest a different potential approach to improving anti-cancer therapy. We have examined the efficacy of the cysteine ‘pro-drug’ L2-oxothiazolidine-4 carboxylate (OTZ) at enhancing normal tissue versus tumor GSH. Animals were treated with OTZ or BSO, and the concentrations of GSH in normal tissues and tumor were measured. We found that the presence of the tumor itself decreased bone marrow GSH, but that OTZ significantly increased it in this setting. Interestingly, OTZ administration significantly depleted tumor GSH levels to the same level as did BSO. OTZ could offer a selective biochemical modulation of GSH.

Regioselective preparation and NMR spectroscopy study of 2-chloro-4-ethoxy-quinoline for the synthesis of 2-((3-aminopropyl)amino)quinolin-4(1H)-one

Herein, we describe the C4-ethoxylation of 2,4-dichloroquinoline to prepare 2-chloro-4-ethoxy-quinoline (3), which is a prominent intermediate used for the synthesis of 2-substituted quinolones. To achieve this goal, we studied different conditions for the reaction between 2,4-dichloroquinoline and sodium ethoxide. We discovered that the use of 18-crown-6 ether as an additive and dimethylformamide as the reaction solvent allowed us to obtain the desired product 3 in very good yield and selectivity. In addition, a definitive distinction between the C2 and C4 ethoxylation products was achieved using 1H?15N heteronuclear multiple bond correlation. Compound 3 is an intermediate used for the synthesis of 2-((3-aminopropyl)amino)quinolin-4(1H)-one, which displays peculiar behavior during 1H nuclear magnetic resonance analysis, such as the broadening of the H8 singlet and unexpected deuteration at the C8-position. Effort has been dedicated to understand these findings.

The progress of the reaction was monitored by TLC. The yields were in the range of 61-86 %. Synthesized compounds were screened for antimicrobial activities against E. coli as Gram negative bacteria and S. aureus as Gram positive bacteria. Some of the compounds displayed pronounced biological activity. The structures of synthesized compounds were elucidated on the basis of spectral (1H NMR,!3 C NMR and IR) and elemental analysis.

A green approach for organic transformations using microwave reactor

Microwave-assisted organic transformation (MAOR) is presently gaining wide popularity in the field of organic synthesis. The conventional heating technique is gradually being removed from the laboratory and a novel microwave heating technique established to be used in both academia and industry. As compared to the classical organic methodology, the green technology tools have several advantages like dramatically reduced reaction times, improved yields, site selectivity, and the increased product purities with simplification of work-up procedures. In the current study, we have briefly described the overview of recent developments and applications of microwave irradiation in organic transformation with schematic compiling of the organic reactions, bioactive heterocyclic compounds, and so on. This review also presents a critical analysis of the various advantages of microwave irradiation in organic synthesis/transformation compared to the classical or conventional heating. So, we believe that our current study of the green microwave heating technique will be highly beneficial for the researchers from both academia and industry in their near future.

Concise and Additive-Free Click Reactions between Amines and CF3SO3CF3

Trifluoromethyl trifluoromethanesulfonate has proved to be an excellent reservoir of difluorophosgene and a promising click ligation for amines in the preparation of urea derivatives, heterocycles, and carbamoyl fluorides under metal- and additive-free conditions. The reactions are rapid, efficient, selective, and versatile, and can be performed in benign solvents, giving products in excellent yields with minimal efforts for purification. The characteristics of the reactions meet the requirements of a click reaction. The use of trifluoromethyl trifluoromethanesulfonate as a click reagent is advantageous over other ?CO? sources (e.g., TsOCF3, PhCO2CF3, CsOCF3, AgOCF3, and triphosgene) because this reagent is readily accessible; easy to scale up; and highly reactive, even under metal- and additive-free conditions. It is anticipated that CF3SO3CF3 will be increasingly as important as SO2F2 as a click agent in future drug design and development.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 2682-49-7, and how the biochemistry of the body works.Electric Literature of 2682-49-7

A NEW SYNTHESIS OF HETEROCYCLES VIA CARBONILATION OF AMINES WITH CARBON MONOXIDE IN THE PRESENCE OF SELENIUM

Amines which contain a second functional group in the appropriate position react with carbon monoxide in the presence of selenium to form heterocyclic derivatives in which carbon monoxide is incorporated.For instance, diamines, aminoalcohols, and their related compounds undergo carbonylation to give cyclic ureas, urethanes and the corresponding carbonylated compounds.For diamines and amino alcohols with more than two carbon atoms between the functional groups, intermolecular carbonylative coupling takes place competing with the intramolecular reaction.High selectivity has been attained under specified reaction conditions.Anilines having cyano or acetyl groups on the ortho position afford new classes of selenium-containing heterocycles.In these reactions, carbamoselenoate has been suggested as the common key intermediate.

The new title 4-thiazolidinone derivative, C 16 H 21 N 3 O 3 S, was obtained from the cyclization reaction of 4-methyl-3-thiosemicarbazone and dimethyl acetylenedicarboxylate (DMAD). The cyclohexylidene ring has an envelope conformation with the stereogenic centre C atom as the flap. Its mean plane makes a dihedral angle of 56.23(9) with the thiazolidine ring mean plane. In the crystal, molecules are linked by C – H?O hydrogen bonds forming chains propagating in the [001] direction. Within the chains there are offset pi-pi interactions between the thiazolidine rings of inversion-related molecules [centroid-centroid distance = 3.703(1)A]. The chains are linked by further C – H?O hydrogen bonds, forming slabs parallel to the ac plane.
