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” L-2-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.

Diastereoselective synthesis of cyclosaligenyl-nucleosyl-phosphotriesters

A diastereoselective synthesis of cycloSal-phosphotriesters (cycloSal=cycloSaligenyl) based on chiral auxiliaries has been developed that allows the synthesis of single diastereomers of the cycloSal-pronucleotides. In previously described synthesis routes, the cycloSal-compounds were always obtained as 1:1 diastereomeric mixtures that could be separated in only rare cases. However, it was shown that the diastereomers have different antiviral activity, toxicity, and hydrolysis stabilities. Here, first a chiral thiazoline derivative was used to prepare nonsubstituted and 5-methyl-cycloSal- phosphotriesters in 48 and ?95%a de (de=diastereomeric excess). However, this approach failed to give the important group of 3-substituted cycloSal-nucleotides. Therefore, two other chiral groups were discovered that allowed the synthesis of (RP)- and (SP)-3-methyl-cycloSal- phosphotriesters as well. The antiviral activity was found to be five- to 20-fold different between the two individual diastereomers, which proved the importance of this approach. Chiral chemical Trojan horses: cycloSal-nucleotides (cycloSal=cycloSaligenyl) of thymidine and cycloSal-pronucleotides of 3?-azido-3?-deoxythymidine (AZT) and 3?-deoxy-2?, 3?-didehydrothymidine (d4T) were prepared by a diastereoselective route for the first time by using a chiral auxiliary approach with up to ?95%a de (see scheme). The procedure is suitable to synthesize cycloSal-phosphotriesters with different substitution patterns in the aromatic residue.

Colorimetric probes based on bioactive organic dyes for selective sensing of cyanide and fluoride ions

Eight novel bioactive azo dyes containing thiazolidinone (TZD) derivatives (1O-4S) were designed and synthesized for antibacterial assays and colorimetric sensing of anions. Synthesized compounds were evaluated for their antibacterial activities using the disc diffusion technique. Majority of the compounds showed potent antibacterial activities against the tested bacterial strains in the zone assay. Moderate antibacterial activities were also exhibited in the minimum inhibitory concentration (MIC) assay. In addition, the synthesized compounds were evaluated for their colorimetric sensing of anions. In contrast to dyes with electron donating groups (EDGs), 4O having electron withdrawing groups (EWGs) showed highly selective colorimetric sensing of CN- ions. Binding interaction of 4O with CN- ions provides a remarkable colorimetric response from yellow to blue (Deltalambda = 186 nm), enabling naked-eye sensing without any spectroscopic instrumentation. Furthermore, the limit of detection (LOD) for 4O towards CN- was found to be 0.74 muM.

Penultimate group effects in free radical telomerizations of acrylamides

The telomerization of several acrylamides, most containing chiral auxiliary groups, was investigated. The first-formed stereogenic center in the n = 2 telomer (the penultimate center) has a significant effect on the configuration of the second (ultimate) center in the product. The penultimate chiral center of oxazolidine-derived acrylamides directs the configuration of the ultimate center such that the erythro n = 2 product is preferred. Sultam-substituted acrylamides preferentially lead, on the other hand, to threo products or give products with little stereoselectivity.

Review on synthetic chemistry and antibacterial importance of thiazole derivatives

Background: Thiazole is one of the leading heterocyclic five-member ring compounds that contain nitrogen and sulphur atom. Many natural and/or synthetic compounds contain thiazole as an essential moiety and possess diverse therapeutic activities. The thiazole ring was modified at different positions to generate new molecules with potent antibacterial activities. Thus, the present review enumerates the antibacterial importance of thiazole and its derivatives. Method: The mining of literature has been performed using different database which includes only peer-reviewed journals. The quality of retrieved papers was appraised using standard tools. Moreover, the significant papers were described in detail to focus on thiazole derivatives showing considerable antibacterial activity. Result: The present review describes the chemistry, SAR (Structure Activity Relationship) studies and antibacterial importance of thiazole with different synthetic procedures. Conclusion: This particular study certainly benefits the researchers interested in exploiting the antibacterial activity of thiazoles in search of novel agents.

Synthesis of new C3 symmetric amino acid- and aminoalcohol-containing chiral stationary phases and application to HPLC enantioseparations

We recently reported a new C3-symmetric (R)-phenylglycinol N-1,3,5-benzenetricarboxylic acid-derived chiral high-performance liquid chromatography (HPLC) stationary phase (CSP 1) that demonstrated better results as compared to a previously described N-3,5-dintrobenzoyl (DNB) (R)-phenylglycinol-derived CSP. Over a decade ago, (S)-leucinol, (R)-phenylglycine, and (S)-leucine derivatives were used as the starting materials of 3,5-DNB-based Pirkle-type CSPs for chiral separation. In this study, three new C3-symmetric CSPs (CSP 2, 3, and 4) were prepared by combining the ideas and results mentioned above. Here we describe the synthetic procedures and applications of the new C3-symmetric CSPs (CSP 2?CSP 4).
