In the current research framework, an efficient and greener synthesis has been developed for novel isoxazole scaffolds one-pot three-component reaction. We have developed a new method for convenient and rapid synthesis of 4-(substituted-1H-pyrazol-4-yl)methylene)-3-isopropylisoxazol-5(4H)-ones via one-pot three-component reaction between methyl 4-methyl-3-oxovalerate, hydroxylamine hydrochloride and various pyrazole aldehyde in the presence of pyridine as a base, water:EtOH (1:1) act as greener solvent under conventional and ultrasonic irradiation methods. From the comparisition between conventional and ultrasound-assisted synthesis, it was observed that the ultrasound-assisted method gave 82?96% yields in 30?45 min against 70?90 min required to get 66?79% yields by a conventional method. All the final compounds were characterized by FT-IR, 1H NMR, 13C NMR and Mass spectroscopic analysis, also evaluate for their in-vitro anti-cancer activity against a panel of 60 different human tumour cell lines derived from all compound highly active leukemia cancer types.

Background: Hispolons are natural products known to possess cytoprotective, antioxidant and anti-cancer activities. We have found recently anti TB activity in these compounds. Efforts were made to optimize the structure with bioisosteric replacement of 1,3-diketo functional group with the corresponding pyrazole and isoxazole moieties. Objective: The goal of this paper is designing new hispolon isoxazole and pyrazole and the evaluation of their biological activities. Methods: The designed compounds were prepared using classical organic synthesis methods. The anti- TB activity was evaluated using the MABA method. Results: A total of 44 compounds were synthesized (1a- 1v and 2a-2v) and screened for anti TB activity and antibacterial activity. The compounds 1b and 1n showed the highest potency with MIC 1.6mug/mL against M. tuberculosis H37Rv. Conclusion: Bioisosteric replacement of 1,3-diketo functional group in hispolons with pyrazole or isoxazole rings have resulted in potent anti TB molecules. Docking simulations of these compounds on mtFabH enzyme resulted in a clear understanding of bioactivity profiles of these compounds. Docking scores are in good agreement with the anti TB activity obtained for these compounds. Computational studies and in vitro screening results indicate mtFabH as the probable target of these compounds.

Hit identification is a crucially important stage gate in the drug discovery process. As the development candidate that emerges from pre-clinical research invariably resembles the initial hit, it is important to make as well-informed a choice as possible when selecting which hits to progress and which to shelve. Decisions made during the hit identification process determine the chemistry direction in which a project proceeds, usually taking into account the potency of the hit, any SAR generated during the hit-finding exercise, the potential scope for generating novel and patentable chemical matter, and the synthetic tractability of the series. Over the last decade, a huge amount of financial and intellectual investment has been made in HTS to identify compounds with low micromolar IC50s, leading to major advances in combinatorial chemistry, high throughput analysis and purification, and compound handling and storage. HTS is constantly improving as the processes are refined and compound collections are improved, but overall results have been disappointing. Recently, structure-guided approaches have been used much more frequently at the hit-finding stage of drug discovery and, as this review seeks to demonstrate, these approaches have had a major impact on a number of kinase targets. The closer integration of these tools, combined with ongoing technological advances in computational chemistry, X-ray crystallography and NMR spectroscopy will inevitably lead to an even greater use of structural techniques for hit generation to complement or replace HTS.

The kinetics of the forward and reverse steps of the reaction [Pt(terpy)Cl]+ + nu ? [Pt(terpy)(nu)]2+ + Cl- (terpy = 2,2?:6?,2?-terpyridine, nu = one of a number of thiazoles, oxazole, isoxazole, imidazole, pyrazole and 3,5-dimethylpyrazole, covering a wide range of basicities) have been studied in methanol at 25 C. Both forward and reverse reactions obey the usual two-term rate law observed in square-planar substitution. The second-order rate constants for the forward reactions, k2f, show a slight dependence upon the basicity of the entering nu, while the steric hindrance due to the presence of one methyl group in the alpha position to the nitrogen markedly decreases the reactivity. The second-order rate constants for the reverse reactions, k2r, are very sensitive to the nature of the leaving group and a plot of log k2r against the pKa of the conjugate acids of the unhindered five-membered N-donors is linear with a slope of -0.51. The results are compared with data from the literature regarding a series of pyridines reacting with the [Pt(terpy)Cl]+ cation under the same experimental conditions. Both in the forward and in the reverse reaction, the reactivity depends not only upon the ligand basicity but also upon the nature of the nucleophile in the order: (thiazoles, oxazole, isoxazole, imidazole, pyrazoles) > pyridines for the entry of N-donors and on the contrary for the displacement by Cl-. Steric retardation, due to the presence of a methyl group in the alpha position to the nitrogen, is remarkably lower for five-membered N-donors if compared to pyridines both in the forward and in the reverse reaction.

Stress granule (SG) assembly is a conserved cellular strategy to minimize stress-related damage and promote cell survival. Beyond their fundamental role in the stress response, SGs have emerged as key players for human health. As such, SG assembly is associated with cancer, neurodegenerative disorders, ischemia, and virus infections. SGs and granule-related signaling circuits are therefore promising targets to improve therapeutic intervention for several diseases. This is clinically relevant, because pharmacological drugs can affect treatment outcome by modulating SG formation. As membraneless and highly dynamic compartments, SGs regulate translation, ribostasis and proteostasis. Moreover, they serve as signaling hubs that determine cell viability and stress recovery. Various compounds can modulate SG formation and dynamics. Rewiring cell signaling through SG manipulation thus represents a new strategy to control cell fate under various physiological and pathological conditions.

The U1 small nuclear ribonucleoprotein 70 kDa (U1-70K) and other RNA-binding proteins (RBPs) are mislocalized to cytoplasmic neurofibrillary Tau aggregates in Alzheimer?s disease (AD), yet the co-aggregation mechanisms are incompletely understood. U1-70K harbors two disordered low? complexity domains (LC1 and LC2) that are necessary for aggregation in AD brain extracts. The LC1 domain contains highly repetitive basic (Arg/Lys) and acidic (Asp/Glu) residues, referred to as a basic-acidic dipeptide (BAD) domain. We report here that this domain shares many of the properties of the Gln/Asn-rich LC domains in RBPs that also aggregate in neurodegenerative disease. These properties included self-assembly into oligomers and localization to nuclear granules. Co-immunoprecipitations of recombinant U1-70K and deletions lacking the LC domain(s) followed by quantitative proteomic analyses were used to resolve functional classes of U1-70K-interacting proteins that depend on the BAD domain for their interaction. Within this interaction network, we identified a class of RBPs with BAD domains nearly identical to that found in U1-70K. Two members of this class, LUC7L3 and RBM25, required their respective BAD domains for reciprocal interactions with U1-70K and nuclear granule localization. Strikingly, a significant proportion of RBPs with BAD domains had elevated insolubility in the AD brain proteome. Furthermore, we show that the BAD domain of U1-70K can interact with Tau from AD brains but not from other tauopathies. These findings highlight a mechanistic role for BAD domains in stabilizing RBP interactions and in potentially mediating co-aggregation with the pathological AD?specific Tau isoforms.

Curcumin (CU), an edible natural pigment from Curcuma Longa, has demonstrated extensive anti-tumor effect in vivo and in vitro. With the property of reversing drug resistance and low toxicity, CU has been considered to develop a new adjuvant chemotherapy protocol of cancer. However, the poor stability, solubility, in vivo bioavailability and weak activity of CU greatly limit its clinical application. Therefore, CU analogues have been extensively studied. Starting from the study of natural CU analogues, multiple approaches are being sought to obtain more stable, soluble and effective analogues of CU. This review focuses on the progress of these approaches to more potent CU analogues.

Nowadays, microalgae are widely discussed as a promising feedstock for biofuel production. For higher crude bio-oil yield with good quality, microalgal biomass productivity and bio-oil characteristics are essential parameters. However, the same microalgal species has different chemical compositions at different growth phases. Therefore, the present study aimed to identify the best growth phase for high biomass productivity and optimal bio-oil production from the green microalga Micractinium conductrix via Py-GC/MS and TGA/MS analysis. M. conductrix was grown in a tubular photobioreactor and harvested at early exponential phase (EEP), middle exponential phase (MEP), late exponential phase (LEP) and stationary phase (STP). LEP showed the maximum significant (P ? 0.05) biomass productivity of 0.058 ± 0.004 g L?1 d-1, with maximum significant lipid and carbohydrate contents (28.7 ± 1.1 and 42.9 ± 1.2%dw, respectively). TGA/MS results confirmed that biomass harvested at MEP and LEP showed higher extent of conversion or mass loss reaction via thermal degradation with the lowest residual solid products. In addition, the hydrocarbon fragments in gaseous products (H2, C2H6, CH4, C2H4) from TGA/MS analysis were found to be released more abundantly at LEP. Moreover, Py-GC/MS results revealed that thermal decomposition of biomass harvested at LEP resulted in the highest significant relative contents of aliphatic hydrocarbons (41.2%) with lowest nitrogen-containing compounds (6.3%). The present study showed the significant impact of harvest time of microalgae on products characteristics of thermal decomposition and nominated LEP as the optimum growth phase to harvest M. conductrix for upgraded bio-oil production.
