Enhanced cellular uptake by non-endocytic pathway for tumor therapy

Endosome/lysosome, as the potential risk of therapeutic inactivation resulting from physical obstruction and a number of acid hydrolases, is a bottleneck in effective intracellular delivery which needs to be overcome. One promising strategy to avoid this barrier is to deliver therapeutic agents directly into the cytoplasm. In this study, CLIP6 peptide (KVRVRVRVDPPTRVRERVK-NH2) which can facilitate non-endosomal cell entry and anticancer drug doxorubicin (DOX) were covalently grafted to N-(2-hydroxypropyl)methacrylamide (HPMA) backbone (P-DOX-CLIP6). As a result, CLIP6 peptide modification increased the cellular uptake of DOX-loaded HPMA copolymers. Importantly, it effectively reduced lysosomal accumulation, leading to stronger proliferation inhibition and superior growth inhibition effect on three-dimensional tumor spheroids, compared to unmodified HPMA copolymer conjugates. Furthermore, P-CLIP6-DOX induced the highest therapeutic efficacy in HeLa tumor-bearing nude mice. Meanwhile, no significant systemic toxicity was observed during the treatment. In conclusion, this study provided a promising strategy to efficiently deliver drug candidates which were limited by endo/lysosomal trapping.

Solid-phase synthesis of a small library of 3-phenylthio-3-nicotinyl propionic acid derivatives acting as antagonists of the integrin alphaVbeta3

We describe the synthesis of a series of low molecular weight inhibitors of the alphavbeta3 integrin obtained by modifying a high-throughput screening hit with micromolar activity. A solid phase synthesis to prepare 3-phenylthio-3-nicotinyl propionic acid derivatives, exemplified by 13c, was set up. Compounds with nanomolar activity in the biochemical assay and able to efficiently inhibit cell adhesion mediated by vitronectin have been obtained.

Arginine and proline applied as food additives stimulate high freeze tolerance in larvae of Drosophila melanogaster

The fruit fly Drosophila melanogaster is an insect of tropical origin. Its larval stage is evolutionarily adapted for rapid growth and development under warm conditions and shows high sensitivity to cold. In this study, we further developed an optimal acclimation and freezing protocol that significantly improves larval freeze tolerance (an ability to survive at -5C when most of the freezable fraction of water is converted to ice). Using the optimal protocol, freeze survival to adult stage increased from 0.7% to 12.6% in the larvae fed standard diet (agar, sugar, yeast, cornmeal). Next, we fed the larvae diets augmented with 31 different amino compounds, administered in different concentrations, and observed their effects on larval metabolomic composition, viability, rate of development and freeze tolerance. While some diet additives were toxic, others showed positive effects on freeze tolerance. Statistical correlation revealed tight association between high freeze tolerance and high levels of amino compounds involved in arginine and proline metabolism. Proline- and arginine-augmented diets showed the highest potential, improving freeze survival to 42.1% and 50.6%, respectively. Two plausible mechanisms by which high concentrations of proline and arginine might stimulate high freeze tolerance are discussed: (i) proline, probably in combination with trehalose, could reduce partial unfolding of proteins and prevent membrane fusions in the larvae exposed to thermal stress ( prior to freezing) or during freeze dehydration; (ii) both arginine and proline are exceptional among amino compounds in their ability to form supramolecular aggregates which probably bind partially unfolded proteins and inhibit their aggregation under increasing freeze dehydration.

Exogenous proline enhances the sensitivity of Tobacco BY-2 cells to arsenate

Arsenic causes physiological and structural disorders in plants. Proline is accumulated as a compatible solute in plants under various stress conditions and mitigates stresses. Here, we investigated the effects of exogenous proline on tobacco Bright Yellow-2 (BY-2) cultured cells under AsO4- stress. Arsenate did not inhibit BY-2 cell growth at 40 and 50 muM but did it at 60 muM. Proline at 0.5 to 10 mM did not affect the cell growth but delayed it at 20 mM. At 40 muM AsO4-, neither 0.5 mM nor 1 mM proline affected the cell growth but 10 mM proline inhibited it. In the presence of AsO4-, 10 mM proline increased the number of Evans Blue-stained (dead) cells and decreased the number of total cells. Together, our results suggest that exogenous proline does not alleviate arsenate toxicity but enhances the sensitivity of BY-2 cells to arsenate.

Intranasal Administration of a Polyethylenimine-Conjugated Scavenger Peptide Reduces Amyloid-beta Accumulation in a Mouse Model of Alzheimer’s Disease

Amyloid-beta (Abeta) aggregation in the brain plays a central and initiatory role in pathogenesis and/or progression of Alzheimer’s disease (AD). Inhibiting Abeta aggregation is a potential strategy in the prevention of AD. A scavenger peptide, V24P(10-40), designed to decrease Abeta accumulation in the brain, was conjugated to polyethylenimine (PEI) and tested as a preventive/therapeutic strategy for AD in this study. This PEI-conjugated V24P(10-40) peptide was delivered intranasally, as nasal drops, to four-month-old APP/PS1 double transgenic mice for four or eight months. Compared with control values, peptide treatment for four months significantly reduced the amount of GdnHCl-extracted Abeta40 and Abeta42 in the mice’s hippocampus and cortex. After treatment for eight months, amyloid load, as quantified by Pittsburgh compound B microPET imaging, was significantly decreased in the mice’s hippocampus, cortex, amygdala, and olfactory bulb. Our data suggest that this intranasally delivered scavenger peptide is effective in decreasing Abeta accumulation in the brain of AD transgenic mice. Nasal application of peptide drops is easy to use and could be further developed to prevent and treat AD.
