Synthesis and molecular docking study of new pyrazole derivatives as potent anti-breast cancer agents targeting VEGFR-2 kinase

Based on the previous studies that revealed the valuable role of pyrazole scaffold in cancer management and VEGFR-2 inhibition, a new set of pyrazole conjugated with pyrazoline, triazolopyrimidine and pyrazolone moieties were synthesized and investigated for their anticancer efficiency against human breast cancer MCF-7. The anticancer screening revealed the significant sensitivity of breast carcinoma towards compounds 4b, 5c, 6c, 7b, 7c and 12c with IC50 values ranging from 16.50 – 26.73 mu M in comparison with tamoxifen (IC50 = 23.31 mu M). Moreover, the new analogues were further examined for their VEGFR-2 inhibitory activity, among the tested derivatives 5c, 6c, 7b, 7c and 12c displayed prominent inhibitory efficiency versus VEGFR-2 kinase with % inhibition ranging from 70 to 79%. Compounds 6c, 7c and 12c revealed inhibitory efficiency in nanomolar level with IC50 (913.51, 225.17 and 828.23 nM, respectively) comparing to sorafenib (IC50 = 186.54 nM). Flow cytometric analysis revealed that the promising compound 12c prompted pre-G1 apoptosis and cell growth cessation at G2/M phase and stimulated apoptosis via activation of caspase-3. Moreover, molecular docking study of the promising derivatives was performed to highlight their binding modes and interactions with the amino acid residues of VEGFR-2 enzyme.

Monocarboxylate transporter 1 and 4 inhibitors as potential therapeutics for treating solid tumours: A review with structure-activity relationship insights

Development of multidrug resistance (MDR) is one of the major causes leading to failure of cancer chemotherapy and radiotherapy. Monocarboxylate transporters (MCTs) MCT1 and MCT4, which are overexpressed in solid tumours, play a very important role in cancer cell survival and proliferation. These lactate transporters work complimentarily to drive lactate shuttle in tumour cells, which results in maintenance of H+ ion (pH) balance necessary for their survival. Inhibition of these transmembrane proteins has been demonstrated as a novel strategy to treat drug resistant solid cancers. Presently, only a few small molecule MCT1 inhibitors such as AZD3965 and AR-C155858 are known with clinical potential. Even lesser mention of MCT4 inhibitors, which include molecules having scaffolds such as pyrazole and indazole, is available in the literature. Current overview presents the status of recent developments undertaken in identification of efficacious MCT1 and/or MCT4 inhibitors as a potential anticancer therapy overcoming MDR. Further, detailed structure-activity relationships for different classes of compounds has been proposed to streamline the understandings learnt from ongoing research work. Through this review, we aim to highlight the importance of these excellent targets and facilitate future development of selective, potent and safe MCT1 and/or MCT4 inhibitors as promising chemotherapy for drug resistant cancer.

Solid-liquid equilibrium solubility, thermodynamic properties and solvent effect of 3,4-dinitro-1H-pyrazole in different pure solvents

Knowledge of solubility and thermodynamic properties of 3,4-dinitro-1H-pyrazole (DNP) within different solvents are essential in the processes of crystallization and further theoretical studies. In this study, the solubility of DNP in 12 pure solvents (i.e., water, n-propanol, isobutyl alcohol, n-pentanol, isoamyl alcohol, xylene, ethyl acetate, epichlorohydrin, chloroform, acetonitrile, tetrahydrofuran and 2-butanone) has been determined by using gravimetric method within the temperature range of (283.15-323.15) K under atmospheric pressure. Good dissolution ability was found for DNP in the organic solvents we studied. The sequence of the mole fraction solubility is tetrahydrofuran >2-butanone > n-propanol > n-pentanol > isobutyl alcohol > isoamyl alcohol > acetonitrile > ethyl acetate > epichlorohydrin > xylene > water > chloroform. Solubility of DNP increased with the increasing temperature in each pure solvent. In addition, solubility data was correlated by four models including the modified Apelblat equation, NRTL model, Wilson model and Two-Suffix Margules model. The maximum rootmean-square deviation (10(4)RMSD) was 715.47. Basically speaking, values of R-2 and 10(4)RMSD between experimental and calculated solubility showed that NRTL model provided most satisfactory fitting results in this work. Moreover, Hansen solubility parameters (delta(d), delta(p), delta(h), delta(t), delta(v) and Delta delta(t)) were used to describe the dissolution characteristics of solid in different solvents. Then, the Kamlet-Taft parameters (alpha, beta and pi*) were explained to investigate the solvent effect on DNP solubility. Furthermore, other parameters, including mixing enthalpy (Delta H-mix) mixing entropy (Delta S-mix) and mixing Gibbs energy (Delta(mix)G) were calculated according to the Wilson model, and their results have been discussed on the basis of experimental data. It has been found that all mixing Gibbs energy are less than zero, hence, the dissolution of DNP is a spontaneous process. (C) 2020 Elsevier B.V. All rights reserved.

Synergistic Effect of Pendant N Moieties for Proton Shuttling in the Dehydrogenation of Formic Acid Catalyzed by Biomimetic Ir(III)Complexes

Formic acid (FA) is among the most promising hydrogen storage materials. The development of efficient catalysts for the dehydrogenation of FA via molecular-level control and precise tuning remains challenging. A series of biomimetic Ir complexes was developed for the efficient dehydrogenation of FA in an aqueous solution without base addition. A high turnover frequency of 46510 h(-1)was achieved at 90 degrees C in 1 mFA solution with complex1bearing pendant pyridine. Experimental and mechanistic studies revealed that the integrated pendant pyridine and pyrazole moieties of complex1could act as proton relay and facilitate proton shuttling in the outer coordination sphere. This study provides a new strategy to control proton transfer accurately and a new principle for the design of efficient catalysts for FA dehydrogenation.

Discovery of biphenyl pyrazole scaffold for neurodegenerative diseases: A novel class of acetylcholinesterase-centered multitargeted ligands

Multitargeted ligands have demonstrated remarkable efficiency as potential therapeutics for neurodegenerative diseases as they target multiple pathways involved in the progression of these diseases. Herein, we report first-in-class dual inhibitor of acetylcholinesterase (AChE) and tau aggregation as a novel class of multitargeted ligands for neurodegenerative diseases. The reported biphenyl pyrazole scaffold binds monomeric tau with sub-micromolar affinity and impedes the formation of tau oligomers at early stages. Additionally, the lead compound inhibited AChE activity with an IC50 value of 0.35 +/- 0.02 mu M. Remarkably, the neuroprotective effect of this lead in induced cytotoxicity model of SH-SY5Y neuroblastoma cells is superior to single-targeted AChE and tau-aggregation inhibitors. This scaffold would enable development of new generation of multitargeted ligands for neurodegenerative diseases that function through dual targeting of AChE and monomeric tau.

Recent update on antibacterial and antifungal activity of quinoline scaffolds

Although most of the heterocycles have been reported to possess a significant pharmacological activity, only a few of them, namely quinoline derivatives, have exhibited the finest biological activities. Despite the few medicinal properties of the plain quinoline molecule, its derivatives exhibit diverse pharmacological properties such as anticancer, anti-inflammatory, antibacterial, antiviral, antifungal, antiprotozoal activities, and so on. The potential antimicrobial properties of the quinoline derivatives are evident from the decades of research on these derivatives. Owing to limitations like drug resistance, high cost, severe side effects, and less bioavailability of previously synthesized antimicrobial agents, these drugs have become obsolete in recent years. Hence, the design of more efficient antimicrobial drugs must be given topmost priority. A breakthrough in drug discovery is a must to prevent malevolent microbial diseases. Addressing all these issues, researchers have been continuously contributing to antimicrobial drug discovery. Herein, a short description of the pharmacology of antimicrobial agents such as antibacterials and antifungals synthesized recently is provided. The versatile derivatization of the quinoline moiety leading to significant antimicrobial potencies is discussed, considering the structure-activity relationship.
