Photoreductive Removal of O-Benzyl Groups from Oxyarene N-Heterocycles Assisted by O-Pyridine-pyridone Tautomerism

Facile photoreductive protocols have been developed to remove benzyl O-protective groups from oxyarene N-heterocycles at positions capable for 2-/4-O-pyridine-2-/4-pyridone tautomerism. Blue light irradiation, a [Ru] or [Ir] photocatalyst, and ascorbic acid in a water-acetonitrile solution debenzylates a variety of aryl N-heterocycles cleanly and selectively. Ascorbic acid has two functions in the reaction. On the one hand, it protonates the N-heterocycles that reduces their reduction potentials notably and on the other hand it acts as a sacrificial reductant. Reduction potentials and free energy barriers calculated at the CPCM-B3LYP/6-31+G? level can predict the reactivities of the studied substrates.

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 1055361-35-7, you can also check out more blogs about1055361-35-7

Protective effects of zingerone derivate on ionizing radiation-induced intestinal injury

Intestinal injury is the primary toxicity of radiotherapy for pelvic and abdominal tumors, and it is also one of the common acute complications of radiotherapy. At present, there are no effective drugs to prevent intestinal injury in the clinic. Zingerone is a natural product with radioprotective effects. In this study, a novel compound (thiazolidine hydrochloride, TZC01) was synthesized by structural modification of zingerone. The effects of TZC01 on preventing intestinal injury from radiation were further investigated in this study. C57BL/6N mice were exposed to a lethal dose of abdominal irradiation (ABI) with and without TZC01 treatments. The morphological changes of the intestine and various makers of intestinal crypt cells were investigated. Treatment with TZC01 improved the survival rate of mice exposed to 12 Gy ABI. Moreover, TZC01 protected the intestinal morphology of mice, decreased the apoptotic rate of intestinal crypt cells, maintained cell regeneration and promoted crypt cell proliferation and differentiation. This study suggests that TZC01 has preventive and therapeutic effects on radiation enteritis by promoting the proliferation and differentiation of crypt cells to protect the small intestine from the toxic effects of ionizing radiation. Furthermore, the study of TCZ01 lays a strong foundation for developing novel radioprotectors with multiple properties.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 14446-47-0 is helpful to your research. Application of 14446-47-0

Novel heterocyclic hybrids based on 2-pyrazoline: Synthesis and assessment of anti-inflammatory and analgesic activities

Aim and Objective: A series of new 2-pyrazoline analogues were synthesized. The structures of the synthesized compounds were elucidated by the analytical and spectroscopic data. Some selected compounds were screened for the anti-inflammatory activity by using animal model of carrageenan-induced paw edema in mice. Additionally, the analgesic and acute toxicity of these compounds were evaluated and exhibited reasonable results. The anti-oxidant and anti-inflammatory effects of these compounds were established by measuring the contents of malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO), and tumor necrosis factor alpha (TNF-alpha) in the edema paw tissue. Materials and Methods: All chemicals and reagents used in current study were of analytical grade. Melting points were determined using APP. Digital ST 15 melting point apparatus and are uncorrected. FT-IR spectra were recorded on a Pye-Unicam SP3-100 spectrophotometer in KBr pellet. All 1H and 13C NMR spectra were recorded on AVANCE-III (400 MHz) High Performance FT-NMR Spectrometer Brucker (Switzerland) and some 1H NMR spectra were recorded on Varian EM-360L NMR Spectrophotometer (60 MHz) (USA) in CDCl3 or DMSO-d6 as solvent. Chemical shifts are reported in sigma units and the coupling constants (J) are reported in hertz. C, H, N and S analyses were performed with a Vario EL C, H, N, S Analyzer. Carrageenan (product number C1013) was obtained from Sigma-Aldrich (USA). Results: The structures of the compounds were confirmed by IR, 1H NMR, 13C NMR, and elemental analyses. The results of pharmacological activity revealed that compounds 5, 6, 7, and 15 could be recognized as potential multi-potent anti-inflammatory. Conclusion: A simple and suitable method for the synthesis of new pharmacophore was reported. We have designed nineteen heterocycles related to pyrazoline ring, and evaluated eleven of them for their antiinflammatory, analgesic and acute toxicity activities. Compounds 5, 6, 7, and 15 proved to be the interesting compounds, they have high anti-inflammatory activity. However, all the selected compounds show remarkable analgesic activity.

BCL6 INHIBITORS AS ANTICANCER AGENTS

The invention provides compositions and methods for blocking the BCL6 BTB domain with small molecule, non-peptide compounds as disclosed and claimed herein. BCL6 is a transcriptional repressor of the BTB-POZ (bric a brac, tramtrack, broad complex / pox virus zinc finger) family of proteins. It is required for normal development of germinal center (GC) B-cells and is also the most commonly involved oncogene in diffuse large B-cell lymphomas (DLBCLs), and constitutive expression of BCL6 in GC B-cells causes DLBCL in mice. DLBCLs are aggressive tumors that arise from germinal center (GC) B- cells and are the most common form of non-Hodgkin’s lymphomas. BCL6 is required for survival of DLBCL cells and can limit their ability to respond to DNA damaging agents. It is also frequently expressed in follicular lymphomas (FLs), and may be required for survival of these tumors as well. DLBCL and FL collectively constitute ?60-70% of B-cell lymphomas and the incidence of these tumors has been rising in recent decades.

Protection against acetaminophen-induced hepatotoxicity by L-CySSME and its N-acetyl and ethyl ester derivatives

We have recently observed that S-(2-hydroxyethylmercapto)-L-cysteine (L-CySSME), the mixed disulfide of L-cysteine and 2-mercaptoethanol, prevented cataracts induced in mice by acetaminophen (ACP) by functioning as a prodrug of L-cysteine and protecting the liver. This prompted the evaluation of the more lipophilic N-acetyl (Ac-CySSME) and ethyl ester (Et-CySSME) derivatives of L-CySSME as proprodrug forms, as well as the “D” enantiomer, as hepatoprotective agents. Serum ALT levels were measured at 24 hours after a toxic but nonlethal dose of ACP that insured 48 hour survival of the animals. Since the increases in ALT produced were highly variable (even after log transformation) and complicated the statistical analyses, we calculated confidence intervals for the mean ALT levels for each treatment group. This enabled comparisons to be made of the efficacy of L-CySSME as well as Ac-CySSME and Et-CySSME with other representative prodrugs of L-cysteine, namely, 2(RS)-methylthiazolidine-4(R)-carboxylic acid (MTCA), L-2-oxothiazolidine-4-carboxylic acid (OTCA), and N-acetyl-L-cysteine (NAC), in protecting the liver. It was shown that L-CySSME and MTCA administered intraperitoneally at 2.5 mmol/kg were superior to the other cysteine prodrugs at equimolar doses in protecting mice from hepatotoxicity elicited by a 400 mg/kg (2.65 mmol/kg) dose of ACP given i.p. 30 minutes prior to the prodrugs. The “D” form of CySSME was totally without protective effect. Oral doses of the prodrugs even at 2x the i.p. dose were less effective, although MTCA was the most protective.

Phosphoramidates and phosphonamidates (ProTides) with antiviral activity

Following the first report on the nucleoside phosphoramidate (ProTide) prodrug approach in 1990 by Chris McGuigan, the extensive investigation of ProTide technology has begun in many laboratories. Designed with aim to overcome limitations and the key resistance mechanisms associated with nucleoside analogues used in the clinic (poor cellular uptake, poor conversion to the 5?-monophosphate form), the ProTide approach has been successfully applied to a vast number of nucleoside analogues with antiviral and anticancer activity. ProTides consist of a 5?-nucleoside monophosphate in which the two hydroxyl groups are masked with an amino acid ester and an aryloxy component which once in the cell is enzymatically metabolized to deliver free 5?-monophosphate, which is further transformed to the active 5?-triphosphate form of the nucleoside analogue. In this review, the seminal contribution of Chris McGuigan?s research to this field is presented. His technology proved to be extremely successful in drug discovery and has led to two Food and Drug Administration-approved antiviral agents.
