Metastasis is complex, involving multiple genetic, epigenetic, biochemical, and physical changes in the cancer cell and its microenvironment. Cells with metastatic potential are often characterized by altered cellular contractility and deformability, lending them the flexibility to disseminate and navigate through different microenvironments. We demonstrate that mechanoresponsiveness is a hallmark of pancreatic cancer cells. Key mechanoresponsive proteins, those that accumulate in response to mechanical stress, specifically nonmuscle myosin IIA (MYH9) and IIC (MYH14), alpha-actinin 4, and filamin B, were highly expressed in pancreatic cancer as compared with healthy ductal epithelia. Their less responsive sister paralogs-myosin IIB (MYH10), alpha-actinin 1, and filamin A-had lower expression differential or disappeared with cancer progression. We demonstrate that proteins whose cellular contributions are often overlooked because of their low abundance can have profound impact on cell architecture, behavior, and mechanics. Here, the low abundant protein MYH14 promoted metastatic behavior and could be exploited with 4-hydroxyacetophenone (4-HAP), which increased MYH14 assembly, stiffening cells. As a result, 4-HAP decreased dissemination, induced cortical actin belts in spheroids, and slowed retrograde actin flow. 4-HAP also reduced liver metastases in human pancreatic cancer-bearing nude mice. Thus, increasing MYH14 assembly overwhelms the ability of cells to polarize and invade, suggesting targeting the mechanoresponsive proteins of the actin cytoskeleton as a new strategy to improve the survival of patients with pancreatic cancer. Significance: This study demonstrates that mechanoresponsive proteins become upregulated with pancreatic cancer progression and that this system of proteins can be pharmacologically targeted to inhibit the metastatic potential of pancreatic cancer cells.

Delivering peptides and proteins with intracellular function represents a promising avenue for therapeutics, but remains a challenge due to the selective permeability of the plasma membrane. The successful delivery of cytosolically active proteins would enable many opportunities, including improved vaccine development through major histocompatibility complex (MHC) class I antigen display. Extended research using cell-penetrating peptides (CPPs) has aimed to facilitate intracellular delivery of exogenous proteins with some success. A new class of polymer-based mimics termed protein transduction domain mimics (PTDMs), which maintain the positive charge and amphiphilic nature displayed by many CPPs, was developed using a poly-norbornene-based backbone. Herein, we use a previously characterized PTDM to investigate delivery of the model antigen SIINFEKL into leukocytes. Peptide delivery into over 90% of CD14+ monocytes was detected in less than 15 min with nominal inflammatory cytokine response and high cell viability. The co-delivery of a TLR9 agonist and antigen using the PTDM into antigen presenting cells in vitro showed presentation of SIINFEKL in association with MHC class I molecules, in addition to upregulation of classical differentiation markers revealing the ability of the PTDM to successfully deliver cargo intracellularly and show application in the field of immunotherapy.

Samarium diiodide (SmI2) is one of the most widely used single electron reductants available to organic chemists because it is effective in reducing and coupling a wide range of functional groups. Despite the broad utility and application of SmI2 in synthesis, the reagent is used in stoichiometric amounts and has a high molecular weight, resulting in a large amount of material being used for reactions requiring one or more equivalents of electrons. few approaches to develop catalytic reactions have been designed, they are not widely used or require specialized conditions. As a consequence, general solutions to develop catalytic reactions of Sm(II) remain elusive. Herein, we report mechanistic studies on catalytic reactions of Sm(II) employing a terminal magnesium reductant and trimethylsilyl chloride in concert with a non coordinating proton donor source. Reactions using this approach permitted reductions with as little as 1 mol % Sm. Mechanistic studies provide strong evidence that during the reaction, SmI2 transforms into SmCl2, therefore broadening the scope of accessible reactions. Furthermore, this mechanistic approach enabled catalysis employing HMPA as a ligand, facilitating the development of catalytic Sm(II) 5-exo-trig ketyl olefin cyclization reactions. The initial work described herein will enable further development of both useful and user-friendly catalytic reactions, a long-standing, but elusive goal in Sm(II) chemistry.

We herein report a facile and high yielding protocol for silica-supported heterogeneous catalysts-mediated synthesis of chalcones. A comparison of results of our synthesis with conventional synthetic protocols is also being offered to assess the efficiency of the prepared catalysts. Biological evaluation of the newly synthesized compounds as urease inhibitors was performed. Most of the compounds were found to have potent urease inhibition activity. The chalcone 3-(3-hydroxyphenyl)-1-phenylpropenone was found to be the most potent with percentage inhibition 86.17 +/- 0.89 and half maximal inhibitory concentration (IC50) value 11.51 +/- 0.03 mu M. The molecular docking study emphasized that the same congeners 3-(furan-2-yl)-1-(4-hydroxyphenyl)propenone, 3-(4-hydroxyphenyl)-1-(4-methoxyphenyl)propanone, and 3-[4-(dimethylamino)phenyl]-1-(p-tolyl)propenone showed very good inhibitory potential against urease and show a higher docking scores 5718, 5940, 5596 and an ACE of – 246.66, – 244.79, and – 243.06 kJ/mol, respectively than the control ligand.

The microtubule is composed of alpha beta-tubulin heterodimers and is an attractive target for the design of anticancer drugs. Over the years, various compounds have been developed and their effect on tubulin polymerization has been studied. Despite great efforts to make an effective drug, no drug has been introduced which inhibit colchicine binding site. In the current work, a series of pyrimidine derivatives were designed and synthesized. Furthermore, their cytotoxic activities were evaluated and molecular docking studies were performed. Twenty compounds of pyrimidine were synthesized in 2 different groups. In the first group, 4,6-diaryl pyrimidine was connected to the third aryl group via thiomethylene spacer. In the second group, this linker was substituted by S-CH2-triazole moiety. The cytotoxic activity of these compounds was evaluated against 4 different cell lines (HT-29, MCF-7, T47D, NIH3T3). Compounds 6d, 6m, 6p showed potent cytotoxic activity against MCF7 cancerous cell lines. Between these compounds, compound 6p did not show cytotoxic activity against NIH- 3T3 (normal cell) cell line. Docking studies show that these compounds occupy colchicine binding site in tubulin protein and probably their anticancer mechanism is inhibition of tubulin polymerization. Altogether, with respect to obtained results, it is attractive and beneficial to further investigation on pyrimidine scaffold as antimitotic agents. Attention to the selectivity index of 6p on MCF7 cell line could be valuable in design new chemical agents for the treatment of breast cancer.

The equilibrium acidity scale (pK(a) scale) in acetonitrile has been supplemented by numerous new compounds and new Delta pK(a) measurements. It now contains altogether 231 acids – over twice more than published previously – linked by 569 Delta pK(a) measurements and spans between the pK(a) values of hydrogen iodide (2.8) and indole (32.57), covering close to 30 orders of magnitude. Measurement results acquired over the last 15 years were added to the scale and new least-squares treatment was carried out. The treatment yielded revised pK(a) values for the compounds published previously, with the root mean square difference between revised and previous values 0.04, demonstrating very good stability of the scale. Correlation equations were developed for estimating pK(a) values for the studied types of compounds in water, DMSO, DMF, and 1,2-dichloroethane on the basis of pK(a) values in acetonitrile. These equations enable predicting pK(a) values with an average error around or less than 1 pK(a) unit, which is a sufficient accuracy for many applications. The scale is expected to be a useful tool for the widest possible research areas in organic chemistry, electrochemical power sources, catalysis, etc.
