Use of a systematic pharmacological methodology to explore the mechanism of Shengmai powder in treating diabetic cardiomyopathy

Background: Cardiovascular complications, such as diabetic cardiomyopathy (DCM), are the leading cause of death in diabetic patients. Shengmai Powder (SMP) was found to have cardioprotective effects. Material/Methods: Based on the systematic pharmacological methodology, this research determined the genes of DCM and the known targets of SMP, predicted potential compounds and targets of SMP, constructed networks for DCM and SMP, and performed network analysis. Results: Five network were constructed: (1) the DCM gene PPI network; (2) the Compound-compound target network of SMP; (3) the SMP-DCM PPI network; (4) the Compound-known target network of SMP; (5) and the SMP known target-DCM PPI network. Several DCM and treatment related targets, clusters, signaling pathways, and biological processes were found. Conclusions: SMP is able to regulate glycometabolism-related, lipid metabolism-related, inflammatory response-related, oxidative stress-related signaling pathways, and biological processes and targets, which suggests that SMP may have a therapeutic effect on DCM.

The potential of secondary metabolites from plants as drugs or leads against protozoan neglected diseases – Part II

Infections with protozoan parasites are a major cause of disease and mortality in many tropical countries of the world. Diseases caused by species of the genera Trypanosoma (Human African Trypanosomiasis and Chagas Disease) and Leishmania (various forms of Leishmaniasis) are among the seventeen “Neglected Tropical Diseases” (NTDs) defined by the WHO. Furthermore, malaria (caused by various Plasmodium species) can be considered a neglected disease in certain countries and with regard to availability and affordability of the antimalarials. Living organisms, especially plants, provide an innumerable number of molecules with potential for the treatment of many serious diseases. The current review attempts to give an overview on the potential of such plant-derived natural products as antiprotozoal leads and/or drugs in the fight against NTDs. In part I, a general description of the diseases, the current state of therapy and need for new therapeuticals, assay methods and strategies applied in the search for new plant derived natural products against these diseases and an overview on natural products of terpenoid origin with antiprotozoal potential were given. The present part II compiles the current knowledge on natural products with antiprotozoal activity that are derived from the shikimate pathway (lignans, coumarins, caffeic acid derivatives), quinones of various structural classes, compounds formed via the polyketide pathways (flavonoids and related compounds, chromenes and related benzopyrans and benzofurans, xanthones, acetogenins from Annonaceae and polyacetylenes) as well as the diverse classes of alkaloids. In total, both parts compile the literature on almost 900 different plant-derived natural products and their activity data, taken from over 800 references. These data, as the result of enormous efforts of numerous research groups world-wide, illustrate that plant secondary metabolites represent an immensely rich source of chemical diversity with an extremely high potential to yield a wealth of lead structures towards new therapies for NTDs. Only a small percentage, however, of the roughly 200,000 plant species on earth have been studied chemically and only a small percentage of these plants or their constituents has been investigated for antiprotozoal activity. The repository of plant-derived natural products hence deserves to be investigated even more intensely than it has been up to present.

Benzopyrazinoisoindigo or Its Reduced Form? Synthesis, Clarification, and Application in Field-Effect Transistors

Benzopyrazinoisoindigo, a pigment reported 40 years ago, should be a good candidate for n-type semiconductors if the reported structure is correct. Reinvestigation of this molecule revealed that it is actually (4H,4?H)-benzopyrazinoisoindigo, which could be considered as the reduced form of benzopyrazinoisoindigo, and hence, it is a good candidate for p-type semiconductors. The route toward the synthesis of this molecule was optimized, and a mechanism was accordingly proposed. A field-effect transistor based on this material showed a hole mobility up to 2.5 ¡Á 10-2 cm2 V-1 s-1. An expedient route for the synthesis of unexpectedly alkylated (4H,4?H)-benzopyrazinoisoindigo is developed, which also clarifies the previously reported structure. A mechanism is accordingly proposed. A field-effect transistor based on this material shows a hole mobility up to 2.5 ¡Á 10-2 cm2 V-1 s-1.

Precisely albumin-hitchhiking tumor cell-activated reduction/oxidation-responsive docetaxel prodrugs for the hyperselective treatment of breast cancer

The anticancer efficacy of chemotherapy is greatly limited by short blood circulation and poor tumor selectivity. Thus, anticancer prodrugs with prolonged systemic circulation, tumor-specific distribution and bioactivation, could significantly strengthen the chemotherapy efficacy. Herein, we design two novel tumor cell reduction/oxidation-responsive docetaxel (DTX) prodrugs, DTX-maleimide conjugates with disulfide bond (DSSM) or thioether bond (DSM) linkages, to evaluate the roles of different sensitive linkages in drug release, pharmacokinetics and therapeutic efficacy. An ester bond-linkage prodrug (DM) is utilized as a non-sensitive control. DSSM and DSM show reduction- or oxidation-sensitive release behavior, respectively, and exhibit hyperselective bioactivation and cytotoxicities between cancerous and normal cells. They could instantly hitchhike blood circulating albumin after i.v. administration with albumin-binding half-lives as short as 1 min, resulting in prolonged systemic circulation, increased tumor accumulation. In response to the upregulated reduction/oxidation environment within tumor cells, DSSM and DSM exhibit selectively release capacity in tumor tissues, their TAITumor/Liver values are over 30-fold greater than DM. Combining the above delivery advantages into one, DSSM and DSM achieve enhanced antitumor efficacy of DTX. Such a uniquely developed strategy, integrating high albumin-binding capability and reduction/oxidation-sensitive drug superselective release in tumors, has great potential to be applied in clinical cancer therapy.

A road map for prioritizing warheads for cysteine targeting covalent inhibitors

Targeted covalent inhibitors have become an integral part of a number of therapeutic protocols and are the subject of intense research. The mechanism of action of these compounds involves the formation of a covalent bond with protein nucleophiles, mostly cysteines. Given the abundance of cysteines in the proteome, the specificity of the covalent inhibitors is of utmost importance and requires careful optimization of the applied warheads. In most of the cysteine targeting covalent inhibitor programs the design strategy involves incorporating Michael acceptors into a ligand that is already known to bind non-covalently. In contrast, we suggest that the reactive warhead itself should be tailored to the reactivity of the specific cysteine being targeted, and we describe a strategy to achieve this goal. Here, we have extended and systematically explored the available organic chemistry toolbox and characterized a large number of warheads representing different chemistries. We demonstrate that in addition to the common Michael addition, there are other nucleophilic addition, addition-elimination, nucleophilic substitution and oxidation reactions suitable for specific covalent protein modification. Importantly, we reveal that warheads for these chemistries impact the reactivity and specificity of covalent fragments at both protein and proteome levels. By integrating surrogate reactivity and selectivity models and subsequent protein assays, we define a road map to help enable new or largely unexplored covalent chemistries for the optimization of cysteine targeting inhibitors.

Radical copolymerization of functional N-substituted maleimides with N-vinyl-2-pyrrolidone

Two functional N-substituted maleimide monomers, namely N-(4-carboxyphenyl)maleimide (CPMI) and N-(4-formylphenoxy-4?- carbonylphenyl) maleimide (FCPMI), were copolymerized with N Vinyl-2-pyrrolidone (NVP) at 90 C in the presence of 2,2?-azobisisobutyronitrile as initiator in dimethylformamide. The monomers reactivity ratios were calculated by extended Kelen-Tu?do?s and Mao-Huglin methods. The average reactivity ratios and Alfrey-Price Q and e Values were found to be r1 = 0.028, r2 = 0.347, Q1 = 0.035, e1 = 1.013 for CPMI/NVP system and r1 = 0.044, r2 = 0.060, Q1 = 0.145, e1 = 1.297 for the FCPMI/NVP system. The distribution of monomer sequences along the copolymer chain was calculated using a statistical method based on the obtained reactivity ratios. The thermal properties of the resulting copolymers were also investigated. These copolymers exhibit fairly high thermal stability with decomposition temperatures above 230 C. The effect of the N-substituents on the radical copolymerization of the above functional maleimides with NVP is discussed.

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.COA of Formula: C11H7NO4, you can also check out more blogs about17057-04-4

Simultaneous qualitative and quantitative evaluation of Toddalia asiatica root by using HPLC-DAD and UPLC-QTOF-MS/MS

Introduction: Coumarin and alkaloids are the major bioactive constituents of Toddalia asiatica, playing an important role in various biological activities such as anti-inflammatory, analgesic, anti-bacterial and anti-tumour. Objective: To establish a method that will simultaneously determine the coumarins and alkaloids compounds in T. asiatica and identify their characteristic fragmentation patterns, while combining fingerprints and chemical identification with chemometrics for discrimination and quality assessment of T. asiatica samples. Methodology: Qualitative characterisation of coumarins and alkaloids compounds in the methanol extracts of T. asiatica was determined by ultra-high-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UPLC-QTOF-MS/MS). Quantitative analysis relies on high-performance liquid chromatography with a diode array detector (HPLC-DAD). Results: A total of 59 components were characterised by UPLC-QTOF-MS/MS, including 29 coumarin, 25 alkaloids, one phenolic acid and four flavonoids. While the 19 characteristic components out of 23 common peaks in the chromatographic fingerprints of T. asiatica were confirmed. Quantitative analysis of seven major compounds from 18 samples were simultaneously detected by HPLC-DAD at wavelengths of 280?nm. The samples were classified into three groups by hierarchical clustering analysis (HCA) combined with principal component analysis (PCA), and orthogonal partial least squares discriminant analysis (OPLS-DA) which screened out the main chemical markers responsible for the samples differences. Conclusion: Fingerprints combined with chemometrics and chemical identification are a simple, rapid and effective method for the quality control of T. asiatica.

CYP2C19 progress curve analysis and mechanism-based inactivation by three methylenedioxyphenyl compounds

Several in vitro criteria were used to assess whether three methylenedioxyphenyl (MDP) compounds, the isoquinoline alkaloids bulbocapnine, canadine, and protopine, are mechanism-based inactivators of CYP2C19. The recently reported fluorometric CYP2C19 progress curve analysis approach was applied first to determine whether these alkaloids demonstrate time-dependent inhibition. In this experiment, bulbocapnine, canadine, and protopine displayed time dependence and saturation in their inactivation kinetics with KI and kinact values of 72.4 ¡À 14.7 muM and 0.38 ¡À 0.036 min-1, 2.1 ¡À 0.63 muM and 0.18 ¡À 0.015 min -1, and 7.1 ¡À 2.3 muM and 0.24 ¡À 0.021 min -1, respectively. Additional studies were performed to determine whether other specific criteria for mechanism-based inactivation were fulfilled: NADPH dependence, irreversibility, and involvement of a catalytic step in the enzyme inactivation. CYP2C19 activity was not significantly restored by dialysis when it had been inactivated by the alkaloids in the presence of a NADPH-regenerating system, and a metabolic-intermediate complex-associated increase in absorbance at approximately 455 nm was observed. In conclusion, the CYP2C19 progress curve analysis method revealed time-dependent inhibition by these alkaloids, and additional experiments confirmed its quasi-irreversible nature. This study revealed that the CYP2C19 progress curve analysis method is useful for identifying novel mechanism-based inactivators and yields a wealth of information in one run. The alkaloids bulbocapnine, canadine, and protopine, present in herbal medicines, are new mechanism-based inactivators and the first MDP compounds exhibiting quasi-irreversible inactivation of CYP2C19.
