Exploring indole derivatives as myeloid cell leukaemia-1 (Mcl-1) inhibitors with multi-QSAR approach: a novel hope in anti-cancer drug discovery

In humans, the over-expression of Mcl-1 protein causes different cancers and it is also responsible for cancer resistance to different cytotoxic agents. Thus, discovery of potential inhibitors of Mcl-1 is very important and both the pharmaceutical industry and academia are looking at it in the quest for new anticancer drugs. In the present study, different molecular modelling techniques such as recursive partitioning, Bayesian classification, structural and physico-chemical interpretation analysis and pharmacophore mapping were employed in order to identify the crucial structural fingerprints important for the optimization of 143 indole derivatives as Mcl-1 inhibitors. These modelling studies emphasize that hydrophobic naphthyl rings, methyl-substituted 1H-pyrazole moiety, N(1)-tethered morpholinoethyl group, chloro substitutions at the 6th position of indole nucleusetc.are beneficial for Mcl-1 binding. Finally, statistically validated classical QSAR and machine learning-based models were also developed for screening and prediction of different indole derivatives as Mcl-1 inhibitors. The modelling analyses will help medicinal chemists to design potent Mcl-1 inhibitors in future. Thus, the present study was an attempt to speed up the anticancer drug discovery of indole-based Mcl-1 inhibitors.

The sensor exhibits a working concentration range of 1.0 x 10(-5)-1.0 x 10(-1) mol L-1 and a detection limit of 1.7 x 10(-6) mol L-1. The sensor shows good selectivity for chromium(III) ions over a number of cations including alkali, alkaline earth, heavy and transition metals. The response time of the sensor is 8 s. In addition, the developed sensor shows good reusability and stability. The sensor operates in the wide pH range of 5.0-11.0.

Electronic Fine-tuning of Ruthenium(II) Transfer Hydrogenation Catalysts with Ethanol as the Hydrogen Source

A series of ruthenium(II) complexes bearing tridentate N,N’-diallyl-2,6-di(5-butylpyrazol-3-yl)pyridine ligands was synthesized and characterized. Introduction of substituents in the 4-position of the pyrazole rings tune the electron density at the ruthenium center, which was proved by correlation of the P-31 NMR chemical shifts with the sigma(p) parameters of the Hammett equation. The structural elucidation of a phosphine-free ruthenium(II) complex proves that one of the allyl side-chains undergoes chelating coordination to the ruthenium site to realize a 18 VE center. This compound is the starting point for complexes of the type (N,N,N)Ru(L)(Cl)(2) bearing ligands L other than triphenylphosphine. The ruthenium(II) complexes were investigated for their activity in the transfer hydrogenation with ethanol as the hydrogen source. Here the logarithms of the measured turn-over frequencies (TOF) correlate with the sigma(p) parameters of the Hammett equation in terms of a linear free-energy relationship.

Anticancer potency of copper(II) complexes of thiosemicarbazones

Being a structural and catalytic cofactor in a number of biological pathways, copper accumulates in tumors owing to selective permeability of the cancer cell membranes. Copper(II) ion forms the active centers in a large number of metalloproteins. The coordination of Schiff’s base ligands to the metal ion results in the high extent of increase in anticancer activity. The copper(II) complexes can cleave DNA through oxidative and hydrolytic pathways, cell apoptosis via intrinsic reactive oxygen species (ROS) mediated mitochondrial pathway due to excessive production of ROS and hence, are found more active than Ni and Pt complexes. Flexible Cu(I/II) redox behavior helps the copper complexes to form more potent, clinically effective and less toxic copper based antiproliferative drugs of lower IC50 value and higher growth inhibitory activity.

17 beta-Estradiol Protects Neural Stem/Progenitor Cells Against Ketamine-Induced Injury Through Estrogen Receptor beta Pathway

Ketamine inhibits neural stem/progenitor cell (NSPC) proliferation and disrupts normal neurogenesis in the developing brain. 17 beta-Estradiol alleviates neurogenesis damage and enhances behavioral performance after ketamine administration. However, the receptor pathway of 17 beta-estradiol that protects NSPCs from ketamine-induced injury remains unknown. In the present study, we investigated the role of estrogen receptor alpha (ER-alpha) and estrogen receptor beta (ER-beta) in 17 beta-estradiol’s protection against ketamine-exposed NSPCs and explored its potential mechanism. The primary cultured NSPCs were identified by immunofluorescence and then treated with ketamine and varying doses of ER-alpha agonist 4,4 ‘,4 ”-(4-propyl-[1H]-pyrazole-1,3,5-triyl) trisphenol (PPT) or ER-beta agonist 2,3-bis(4-hydroxyphenyl)-propionitrile (DPN) for 24 h. NSPC proliferation was analyzed by 5-bromo-2-deoxyuridine incorporation test. The expression of phosphorylated glycogen synthase kinase-3 beta (p-GSK-3 beta) was quantified by western blotting. It was found that treatment with different concentrations of PPT did not alter the inhibition of ketamine on NSPC proliferation. However, treatment with DPN attenuated the inhibition of ketamine on NSPC proliferation at 24 h after their exposure (P< 0.05). Furthermore, treatment with DPN increased p-GSK-3 beta expression in NSPCs exposed to ketamine. These findings indicated that ER-beta mediates probably the protective effects of 17 beta-estradiol on ketamine-damaged NSPC proliferation and GSK-3 beta is involved in this process Related Products of 50-33-9, One of the oldest and most widely used commercial enzyme inhibitors is aspirin, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 50-33-9.

Cycloalkyl Groups as Subunits of Artificial Carbohydrate Receptors: Effect of Ring Size of the Cycloalkyl Unit on the Receptor Efficiency

1,3,5-Trisubstituted 2,4,6-triethylbenzenes consisting of isopropyl groups as recognition units have previously been shown to have interesting binding properties towards selected carbohydrates. The design of such artificial carbohydrate receptors was inspired by the mode of action of carbohydrate-binding proteins, namely by the participation of the isopropyl side chain of valine in the formation of van der Waals interactions with the carbohydrate substrate. This study aimed to investigate how the replacement of the isopropyl groups by other structural motifs, such as cycloalkyl groups of varying sizes (three to seven-membered rings), influences the binding properties of the acyclic compounds towards carbohydrates. The cyclopropyl moiety represents a cyclic analog of the isopropyl group, whereas the other cycloalkyl units can be regarded as structural elements, which differ from the structure of the isopropyl group by a -(CH2)(n)-bridge (n= 1-4) between the two methyl groups. Furthermore, according to the natural interactions, the cyclopentyl group should be able to participate in the formation of van der Waals contacts in a similar way as that observed for the pyrrolidine ring of proline in some protein-carbohydrate complexes. Such systematic binding studies allow the identification of interesting structure-activity relationships, which are very useful for the development of artificial carbohydrate receptors with predictable binding properties.
