HPLC of Formula: C8H12N4, The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

A series of pyridazinylpiperazines were synthesized and evaluated for VR1 antagonist activity in order to improve upon the pharmaceutical and pharmacological properties of BCTC. A structurally biased chemical library of pyridazinylpiperazine analogs was prepared in an effort to improve the pharmaceutical and pharmacological profile of the lead compound N-(4-tertiarybutylphenyl)-4-(3-chloropyridin-2-yl)tetrahydropyrazine-1(2H) -carboxamide (BCTC). The library was evaluated for VR1 antagonist activity in capsaicin-induced (CAP) and pH 5.5-induced (pH) FLIPR assays in a human VR1-expressing HEK293 cell line. The most potent VR1 antagonists were found to have IC50 values in the range of 9-200 nM with improved pharmaceutical and pharmacological profiles versus the lead BCTC. These compounds represent possible second-generation BCTC analogs.

The widespread application of herbicides impacts surface water and groundwater. Metabolites (e.g., desphenylchloridazon from chloridazon) may be persistent and even more polar than the parent herbicide, which increases the risk of groundwater contamination. When parent herbicides are still applied, metabolites are constantly formed and may also be degraded. Evaluating their degradation on the basis of concentration measurements is, therefore, difficult. This study presents compound-specific stable-isotope analysis (CSIA) of nitrogen- and carbon-isotope ratios at natural abundances as an alternative analytical approach to track the origin, formation, and degradation of desphenylchloridazon (DPC), the major degradation product of the herbicide chloridazon. Methods were developed and validated for carbon- and nitrogen-isotope analysis (delta13C and delta15N) of DPC by liquid chromatography-isotope-ratio mass spectrometry (LC-IRMS) and derivatization gas chromatography-IRMS (GC-IRMS), respectively. Injecting standards directly onto an Atlantis LC-column resulted in reproducible delta13C-isotope analysis (standard deviation <0.5?) by LC-IRMS with a limit of precise analysis of 996 ng of DPC on-column. Accurate and reproducible delta15N analysis with a standard deviation of <0.4? was achieved by GC-IRMS after derivatization of >100 ng of DPC with 160-fold excess of (trimethylsilyl)diazomethane. Application of the method to environmental-seepage water indicated that newly formed DPC could be distinguished from “old” DPC by the different isotopic signatures of the two DPC sources.

Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are directly involved in the design, creation and manufacturing process of chemical products and materials. Application of 66346-87-0

This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt and/or hydrate and/or prodrug of the compound) that modulate (e.g., agonize) the apelin receptor (also referred to herein as the APJ receptor; gene symbol APLNR). This disclosure also features compositions containing the same as well as other methods of using and making the same. The chemical entities are useful, e.g., for treating a subject (e.g., a human) having a disease, disorder, or condition in which a decrease in APJ receptor activity (e.g., repressed or impaired APJ receptor signaling; e.g., repressed or impaired apelin-APJ receptor signaling) or downregulation of endogenous apelin contributes to the pathology and/or symptoms and/or progression of the disease, disorder, or condition. Non-limiting examples of such diseases, disorders, or conditions include: (i) cardiovascular disease; (ii) metabolic disorders; (iii) diseases, disorders, and conditions associated with vascular pathology; and (iv) organ failure; (v) diseases, disorders, and conditions associated with infections (e.g., microbial infections); and (vi) diseases, disorders, or conditions that are sequela or comorbid with any of the foregoing or any disclosed herein. More particular non-limiting examples of such diseases, disorders, or conditions include pulmonary hypertension (e.g., PAH); heart failure; type II diabetes; renal failure; sepsis; and systemic hypertension.

Hepatocellular carcinoma is one of the most common kind of cancers in clinical, and its clinical treatment is quite difficult. The latest research suggests that pyridazinone with a novel molecular skeleton shows excellent activity against hepatocellular carcinoma in vitro and in vivo. Considering YHHU-759 as the leading compound for reasonable structure modification, a series of 3,3?-bipyridazine derivatives including 8 novel compounds in this study were designed, synthesized and screened for their anti-hepatoma activities against liver cancer cell lines SMMC-7721, BEL-7402 and QGY-7703 in vitro. The result shows that all of the 3,3?-bipyridazine derivatives have good anti-hepatoma activities.

A wide range of alkyl-, aryl- and heteroarylzinc halides were aminated with highly functionalized alkyl, aryl, and heterocyclic azides. The reaction proceeds smoothly at 50 C within 1 h in the presence of FeCl3 (0.5 equiv) to furnish the corresponding secondary amines in good yields. This method was extended to peptidic azides and provided the arylated substrates with full retention of configuration. To demonstrate the utility of this reaction, we prepared two amine derivatives of pharmaceutical relevance using this iron-mediated electrophilic amination as the key step.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst does not appear in the overall stoichiometry of the reaction it catalyzes. “Electric Literature of 141-30-0
