Application of curcumin and its derivatives in tumor multidrug resistance

Malignant tumor endangers seriously the health of all mankind. Multidrug resistance (MDR) is one of the main causes of clinical tumor chemotherapy failure. Curcumin (CUR) has not only antitumor activity but also reversing tumor MDR effect. CUR reverses tumor MDR via regulating related signal pathways or corresponding expressed proteins or gene. When combined with chemotherapeutic agents, CUR can be a chemotherapeutic sensitive agent to enhance chemotherapy efficacy and weaken tumor MDR. On the other hand, to improve the MDR reversal effect of CUR, its derivatives have been extensively studied. Therefore, this article mainly focuses on reviewing the application of CUR and its derivatives in MDR and its mechanism of reversing MDR.

Atmospheric fate of hymexazol (5-methylisoxazol-3-ol): Simulation chamber studies

The gas-phase degradation of hymexazol (5-methylisoxazol-3-ol), a widely used fungicide, was investigated under atmospheric conditions at the European Photoreactor (EUPHORE) in Valencia, Spain, a large outdoor simulation chamber. The rate coefficient for the reaction of hydroxyl radicals with hymexazol was measured using a conventional relative rate technique. A value of the rate coefficient for the reaction of OH radicals with hymexazol, kOH(hymexazol) = (4.9 ± 0.4) × 10-12 cm3 molecule-1 s-1 was determined at 300 ± 5 K and atmospheric pressure. Rate coefficient data for the reaction of OH radicals with isoxazole, the unsubstituted analogue of hymexazol, was also obtained using the relative rate method, kOH (isoxazole) = (1.1 ± 0.1) × 10-12 cm3 molecule-1 s-1. The rate coefficients for photolysis of hymexazol, J(hymexazol) < 5 × 10-6 s-1, and reaction of ozone with hymexazol, kO3(hymexazol) = (3.2 ± 0.6) × 10-19 cm3 molecule-1 s-1, under atmospheric conditions were also determined. The results showed that removal of hymexazol from the atmosphere by photolysis or by reaction with ozone is slow compared to loss by reaction with OH radicals. The available kinetic data suggest that the gas-phase tropospheric degradation of hymexazol will be mainly controlled by reaction with OH and possibly NO3 radicals. The data provide the basis of an estimate for the tropospheric lifetime of approximately 1 day. The atmospheric implications of the use of hymexazol as a fungicide are discussed. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 288-14-2.

IR, 1H NMR and DFT studies of novel bis-Betti base derivatives of 2,6-dihydroxynaphthalene: Thermodynamic control of diastereoselectivity and configurational preference

Diastereoselectivity and configurational preference for synthetic reaction of novel bis-Betti base derivatives of 2,6-dihydroxynaphthalene were studied through density functional theory (DFT). Enthalpy, entropy and Gibbs free energy of reactions as well as stereochemistry, thermodynamic stability and spectroscopic analysis of products were investigated. The calculated 1H nuclear magnetic resonance (NMR) and infrared (IR) spectra of different configurations were compared to experimental data in order to find the preferred isomer. The diastereoselectivity of reaction was estimated through the calculated equilibrium distribution of stereoisomers. According to these results, preparation of bis-Betti bases is an exothermic process accompanied by a decrease in entropy. The calculated gas phase heats of formation of title compounds are positive. Since the energy difference between stereoisomers is quite small, the change of Gibbs free energy during the reaction favors one configuration over other possibilities. These results are in good agreement with the experimental observations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C3H3NO, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 288-14-2, in my other articles.

Recent advances in protein tyrosine phosphatase 1b targeted drug discovery for Type II diabetes and obesity

Background: Protein tyrosine phosphatase 1B (PTP1B) is an important therapeutic target for type II diabetes and obesity because of its pivotal role as a negative modulator in both insulin and leptin signalling pathways. Objective: The discovery of PTP1B inhibitors has been the focus of researchers in both academia and pharmaceutical industry over the last two decades. Results and Conclusion: Though, intense pharmaceutical research in this area has resulted in many potent PTP1B inhibitors, a vast majority of them possessed pTyr mimetic group such as phosphonates, carboxylic acids and sulphamic acids, which led to poor PTP1B selectivity and insufficient in vivo efficacy due to low cell permeability and bioavailability. The availability of X-ray crystallographic structures of PTP1B together with the application of molecular modelling and other innovative strategies led to the development of many potent and selective PTP1B inhibitors with desirable physicochemical properties. This review traces the development of PTP1B inhibitors over the last decade and also records novel PTP1B inhibitors developed recently with greater emphasis on their selectivity and cell permeability.

Synthesis and Structure Activity Relationships of Chalcone based Benzocycloalkanone Derivatives as Adenosine A 1 and/or A 2A Receptor Antagonists

Adenosine A 1 and/or A 2A receptor antagonists hold promise for the potential treatment of neurological conditions, such as Parkinson’s disease. Herein, a total of seventeen benzocycloalkanone derivatives were synthesised and evaluated for affinity towards adenosine receptors (A 1 and A 2A AR). The obtained results allowed for the conclusion that affinity and/or selectivity of the 2-benzylidene-1-indanone and -tetralone derivatives toward A 1 and/or A 2A ARs may be modulated by the nature of the substituents (either -OH, -OCH 3 or morpholine) attached at position C4 of the 1-indanone core and C5 of the 1-tetralone core as well as the meta (C3′) and/or para (C4′) position(s) on ring B. Several compounds (2a – b, 3b – c and 4a – b) possessed affinity for the A 1 and/or A 2A AR below 10 muM. Additionally, compounds 2a, 3b and 4a were A 1 AR antagonists. These results, once again, confirmed the importance of C4 methoxy-group substitution on ring A in combination with meta (C3′) and/or para (C4′) hydroxyl-group substitution ring B of the 2-benzylidene-1-indanone scaffold leading to drug-like compounds 1h and 1j with affinity in the nanomolar-range.

An overview on medicinal perspective of thiazolidine-2,4-dione: A remarkable scaffold in the treatment of type 2 diabetes

Diabetes or diabetes mellitus is a complex or polygenic disorder, which is characterized by increased levels of glucose (hyperglycemia) and deficiency in insulin secretion or resistance to insulin over an elongated period in the liver and peripheral tissues. Thiazolidine-2,4-dione (TZD) is a privileged scaffold and an outstanding heterocyclic moiety in the field of drug discovery, which provides various opportunities in exploring this moiety as an antidiabetic agent. In the past few years, various novel synthetic approaches had been undertaken to synthesize different derivatives to explore them as more potent antidiabetic agents with devoid of side effects (i.e., edema, weight gain, and bladder cancer) of clinically used TZD (pioglitazone and rosiglitazone). In this review, an effort has been made to summarize the up to date research work of various synthetic strategies for TZD derivatives as well as their biological significance and clinical studies of TZDs in combination with other category as antidiabetic agents. This review also highlights the structure-activity relationships and the molecular docking studies to convey the interaction of various synthesized novel derivatives with its receptor site.

Directing group assists in transition metal-catalyzed site-selective C-H bond activation/transformations

In the review paper, we attempt to point out the importance of the directing group in the transition metal-catalyzed C-H bond activation/transformations, especially in the site-selectivity and reactivity. The employment of the directing groups in the type of reaction can enable a chemist to straightforwardly approach the desired molecular skeletons. Thus, understanding the role of the directing groups in the C-H bond activation/transformations would benefit chemists to design better auxiliary groups and develop more efficient and practical synthetic methodologies. We believe that the synthetic strategy based on the utility of the directing group to assist in the transition metal-catalyzed C-H bond activation/transformations will keep playing as a mainstream role in the research field.

Photolysis of 3,5-diphenylisoxazole in argon matrices

Broadband irradiation of 3,5-diphenylisoxazole 1 in an argon matrix results in formation of azirine 3. Further irradiation of the matrix reduces the amount of azirine 3 with concurrent formation of ylide 4. Thus, it is theorized that the conversion of isoxazole 1 to azirine 3 goes through a triplet vinylnitrene 2 that does not intersystem cross to ketenimine 6. Hence, the reactivity of triplet vinylnitrene 2 is different from similar vinylnitrene intermediates with alpha-methyl substituents that intersystem cross to form corresponding ketenimines. Density functional theory calculations support the notion that the conjugation of the alpha-phenyl group to the vinylnitrene moiety in vinylnitrene 2 renders it more flexible than vinylnitrenes with alpha-methyl substituents, and therefore, vinylnitrene 2 intersystem crosses to azirine 3, rather than ketenimine 6.
