[C-11]Carbonyl Difluoride-a New and Highly Efficient [C-11]Carbonyl Group Transfer Agent

Herein, the synthesis and use of [C-11]carbonyl difluoride for labeling heterocycles with [C-11]carbonyl groups in high molar activity is described. A very mild single-pass gas-phase conversion of [C-11]carbon monoxide into [C-11]carbonyl difluoride over silver(II) fluoride provides easy access to this new synthon in robust quantitative yield for labeling a broad range of cyclic substrates, for example, imidazolidin-2-ones, thiazolidin-2-ones, and oxazolidin-2-ones. Labeling reactions may utilize close-to-stoichiometric precursor quantities and short reaction times at room temperature in a wide range of solvents while also showing high water tolerability. The overall radiosynthesis protocol is both simple and reproducible. The required apparatus can be constructed from widely available parts and is therefore well suited to be automated for PET radiotracer production. We foresee that this straightforward method will gain wide acceptance for PET radiotracer syntheses across the radiochemistry community.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 6118-51-0. Safety of exo-3,6-Epoxy-1,2,3,6-tetrahydrophthalic Anhydride.

Synthesis and antiviral activity of camphor-based 1,3-thiazolidin-4-one and thiazole derivatives as Orthopoxvirus-reproduction inhibitors

The Orthopoxvirus genus belongs to the Poxviridae family and includes variola virus (smallpox), cowpox virus, monkeypox virus and vaccinia virus (VV). Smallpox is considered one of the great epidemic disease scourges in human history. It has currently been eradicated; however, it remains a considerable threat as a biowarfare or bioterrorist weapon. The poxvirus, VV, serves as a model virus from which new antiviral therapies against Orthopoxviruses can be identified. Here, a series of nitrogen-sulphur containing heterocycles such as 1,3-thiazolidin-4-one and thiazoles containing a 1,7,7-trimethylbicyclo[2.2.1]heptan scaffold were synthesized and screened for their antiviral activity. The bioassay results showed that the 4b, 4c and 4e thiazoles, which contained a substituted benzene ring, were able to inhibit VV reproduction with IC50 values in the 2.4-3.7 micromolar range whilst exhibiting moderate cytotoxicity. Among the thiazolidin-4-one derivatives, compound 8b, which contained a 4-methylbenzylidene group, displayed good inhibitory activity (IC50 = 9.5 M) and moderate toxicity.

Identification of para-Substituted Benzoic Acid Derivatives as Potent Inhibitors of the Protein Phosphatase Slingshot

Slingshot proteins form a small group of dual-specific phosphatases that modulate cytoskeleton dynamics through dephosphorylation of cofilin and Lim kinases (LIMK). Small chemical compounds with Slingshot-inhibiting activities have therapeutic potential against cancers or infectious diseases. However, only a few Slingshot inhibitors have been investigated and reported, and their cellular activities have not been examined. In this study, we identified two rhodanine-scaffold-based para-substituted benzoic acid derivatives as competitive Slingshot inhibitors. The top compound, (Z)-4-((4-((4-oxo-2-thioxo-3-(o-tolyl)thiazolidin-5-ylidene)methyl)phenoxy)methyl)benzoic acid (D3) had an inhibition constant (K-i) of around 4m and displayed selectivity over a panel of other phosphatases. Moreover, compound D3 inhibited cell migration and cofilin dephosphorylation after nerve growth factor (NGF) or angiotensinII stimulation. Therefore, our newly identified Slingshot inhibitors provide a starting point for developing Slingshot-targeted therapies.

Transition-metal-free synthesis of thiazolidin-2-ones and 1,3-thiazinan-2-ones from arylamines, elemental sulfur and CO2

Transfering waste to treasure is highly important in green chemistry. However, it is difficult to realize it efficiently due to the low reactivity, especially the simultaneous utilization of two unreactive feedstocks in one reaction. Herein, we report the first utilization of both elemental sulfur and CO2 in a multi-component reaction to generate valuable thiazolidin-2-ones and 1,3-thiazinan-2-ones. Under transition-metal-free reaction conditions, a variety of easily available arylamines react with elemental sulfur and CO2 (1 atm) to give functional thiazolidin-2-ones and 1,3-thiazinan-2-ones in moderate to good yields via C-H bond functionalization. This strategy is highlighted by high step economy with generation of three bonds in one reaction and good functional groups tolerance.

Antifibrotic and anticancer action of 5-ene amino/iminothiazolidinones

Here we describe the synthesis and the antifibrotic and anticancer activity determination of amino(imino)thiazolidinone derivatives. An efficient one-pot three-component reaction which involved [2 + 3]-cyclocondensation and Knoevenagel condensation was used for the synthesis of 5-ene-2-amino(imino)-4-thiazolidinones. Following amino-imino tautomerism, the compound structures were confirmed by X-ray analysis. Comparison of SRB assays on fibroblasts and cancer cells revealed that compounds which significantly reduced the viability of fibroblasts did not possess an anticancer effect. A series of thiazolidinone derivatives as interesting candidates for further testing has been identified. Among the tested compounds 2-{3-furan-2-ylmethyl-2-[(2-methyl-3-phenylallylidene)hydrazono]-thiazolidin-4-one-5-yl}-N-(3-trifluoromethylphenyl)-acetamide (5), N-(2-methoxyphenyl)-2-[5-(4-oxothiazolidin-2-ylideneamino)-[1,3,4]thiadiazol-2-ylsulfanyl]-acetamide (12), 3-[3-allyl-4-oxo-2-(thiazol-2-ylimino)thiazolidin-5-ylidene]-1,3-dihydroindol-2-one (33), and 5(Z)-(thiophen-2-ylmethylene)-4-(4-chlorophenylamino)thiazol-2-(5H)-one (34) possessed high antifibrotic activity levels, had a similar effect as Pirfenidone, and did not scavenge superoxide radicals. Their antifibrotic potential was confirmed using the xCelligence system. (C) 2016 Elsevier Masson SAS. All rights reserved.

Green synthesis of thiazol-2-ylthiazolidin-4-ones as potential antifungals

MORE (Microwave oriented reaction enhancement) green methodology was utilized to synthesize benzothiazol/thiazol-2-ylthiazolidin-4-ones and relatively assayed for their antifungal activity w.r.t precursors against three agriculturally important phytopathogenic fungi viz. Colletotrichum falcatum, Pyricularia grisea and Ustilago hordei. Thiazol-2-ylthiazolidin-4-ones displayed better inhibition of growth of fungi than their precursor’s thiazol-2-amines, with some compounds showing results comparable to their standard fungicides endorsing the effectiveness of chemical hybridization of thiazoles/benzothiazoles with thiazolidin-4-ones in a single molecule. In silico toxicity of all the compounds was found to be equivalent to the standard fungicides. Lipinski parameters were used to rationalize structure activity relation using statistical analysis software.

In Vitro Effects of the Endocrine Disruptor p,p ‘-DDT on Human Follitropin Receptor

BACKGROUND: 1-chloro-4-[2,2,2-trichloro-1-(4-chlorophenyl) ethyl] benzene (p,p’-DDT) is a persistent environmental endocrine disruptor (ED). Several studies have shown an association between p,p’-DDT exposure and reproductive abnormalities. OBJECTIVES: To investigate the putative effects of p, p’-DDT on the human follitropin receptor (FSHR) function. METHODS AND RESULTS: We used Chinese hamster ovary (CHO) cells stably expressing human FSHR to investigate the impact of p,p’-DDT on FSHR activity and its interaction with the receptor. At a concentration of 5 mu M p, p’-DDT increased the maximum response of the FSHR to follitropin by 32 +/- 7.45%. However, 5 mu M p,p’-DDT decreased the basal activity and did not influence the maximal response of the closely related LH/hCG receptor to human chorionic gonadotropin (hCG). The potentiating effect of p,p’-DDT was specific for the FSHR. Moreover, in cells that did not express FSHR, p,p’-DDT had no effect on cAMP response. Thus, the potentiating effect of p,p’-DDT was dependent on the FSHR. In addition, p,p’-DDT increased the sensitivity of FSHR to hCG and to a low molecular weight agonist of the FSHR, 3-((5methyl)-2-(4-benzyloxyphenyl)- 5-{[2-[3-ethoxy-4-methoxy-phenyl)-ethylcarbamoyl]-methyl}-4-oxo-thiazolidin-3-yl)benzamide (16a). Basal activity in response to p,p’-DDT and potentiation of the FSHR response to FSH by p,p’-DDT varied among FSHR mutants with altered transmembrane domains (TMDs), consistent with an effect of p,p’-DDT via TMD binding. This finding was corroborated by the results of simultaneously docking p, p’-DDT and 16a into the FSHR transmembrane bundle. CONCLUSION: p,p’-DDT acted as a positive allosteric modulator of the FSHR in our experimental model. These findings suggest that G protein-coupled receptors are additional targets of-endocrine disruptors.

Design, synthesis and characterization of novel quinacrine analogs that preferentially kill cancer over non-cancer cells through the down-regulation of Bcl-2 and up-regulation of Bax and Bad

Both quinacrine, which contains a 9-aminoacridine scaffold, and thiazolidin-4-one are promising anticancer leads. In an attempt to develop effective and potentially safe anticancer agents, we synthesized 23 novel hybrid compounds by linking the main structural unit of the 9-aminoacridine ring with the thiazolidin-4-one ring system, followed by examination of their anticancer effects against three human breast tumor cell lines and matching non-cancer cells. Most of the hybrid compounds showed good activities, and many of them possessed the preferential killing property against cancer over non-cancer cells. In particular, 343-(6-chloro-2-methoxy-acridin-9-ylamino)-propy1]-2-(2,6-difluoro-pheny1)-thiazolidin-4-one (11; VR118) effectively killed/inhibited proliferation of cancer cells at IC50 values in the range of 1.2. -2.4 mu M. Furthermore, unlike quinacrine or cisplatin, compound 11 showed strong selectivity for cancer cell killing, as it could kill cancer cells 7.6-fold (MDA-MB231 vs MCF10A) to 14.7-fold (MCF7 vs MCF10A) more effectively than matching non-cancer cells. Data from flow cytometry, TUNEL and Western blot assays showed that compound 11 kills cancer cells by apoptosis through the down-regulation of Bc1-2 (but not Bcl-X-L) survival protein and up-regulation of Bad and Bax pro-apoptotic proteins. Thus, compound 11 is a highly promising lead for an effective and potentially anticancer therapy. (C) 2017 Elsevier Masson SAS. All rights reserved.
