A convenient and efficient domino aryne process was developed under transition-metal-free conditions to generate a range of tetra- and pentacyclic ring systems. This transformation was realized via a 1,2-benzdiyne through a nucleophilic and Diels-Alder reaction cascade using styrene as the diene moiety. Three new chemical bonds, namely one C-N and two C-C bonds, and two benzofused rings could be constructed concomitantly, which was made possible by distinct chemoselective control at both the 1,2-aryne and 2,3-aryne stages. Moreover, in-depth studies were carried out on the domino aryne precursors and controlling the diastereoselectivity.

We report the highly enantioselective synthesis of P-chiral tertiary phosphine oxides featuring an ethynyl group via Cu(i)-catalyzed azide-alkyne cycloaddition. Newly developed chiral pyridinebisoxazolines (PYBOX) bearing a bulky C4 shielding group play an important role in achieving excellent enantioselectivity while suppressing side bis-triazoles formation in desymmetrizing prochiral diethynylphosphine oxides. Notably, by tuning the size of the C4 shielding group, it is possible to achieve excellent remote enantiofacial control in desymmetrizing phosphole oxide-diynes with the prochiral P-center farther from the ethynyl group by four covalent bonds. Time-dependent enantioselectivity is observed for these desymmetric CuAAC reactions, suggesting a synergic combination of a desymmetrization and a kinetic resolution, and our ligands prove to be better than unmodified PYBOX in both steps. This finding contributes to a highly enantioselective kinetic resolution of racemic ethynylphosphine oxides. The resulting chiral ethynylphosphine oxides are versatile P-chiral synthons, which can undergo a number of diversifying reactions to enrich structural diversity.

Damaged cartilage does not readily heal and often requires surgical intervention that only modestly improves outcomes. A synthetic material that could be injected and covalently crosslinked in situ to form a bioactive, mechanically robust scaffold that promotes stem cell chondrogenic differentiation holds promise for next-generation treatment of cartilage lesions. Here, Johnson-Claisen rearrangement chemistry was performed on graphene oxide (GO) to enable functionalization with a primary amine covalently bound to the graphenic backbone through a chemically stable linker. The primary amines are used to form covalent crosslinks with chondroitin sulfate, an important component of cartilage that promotes regeneration, to form a hydrogel (EDAG-CS). The EDAG-CS system gels in situ within 10 min, and the graphenic component imparts improved mechanical properties, including stiffness (320% increase) and toughness (70% increase). EDAG-CS hydrogels are highly porous, resistant to degradation, and enable the growth of human mesenchymal stem cells and their deposition of collagen matrix. This system has potential to improve clinical outcomes of patients with cartilage damage.

The paucity of effective anticancer drugs for successful treatment is a major concern, indicating the strong need for novel therapeutic compounds. In the quest of new molecules, the present study aimed to explore the potential of pyrazolo[3,4-d]pyrimidine derivatives as antiproliferative agents. In vitro anticancer screening of selected compounds was done by the National Cancer Institute’s Developmental Therapeutics Programme against a panel of 60 cancer cell lines. The lead compound PP-31d considerably inhibited the growth of cancer cells, such as NCI-H460 (non-small-cell lung cancer), OVCAR-4 (ovarian cancer), 786-0 (renal cancer), A549 (non-small-cell lung cancer), and ACHN (renal cancer), showing strong anticancer potential, among other derivatives. Kinetic studies of PP-31d on NCI-H460 cells revealed a dose-dependent effect with an IC50 of 2 mu M. The observed inhibition by PP-31d is attributed to the generation of reactive oxygen species and the subsequent induction of cellular apoptosis, as evidenced by the increase in the hypodiploid (subG1) population, the early apoptotic cell population, and caspase-3/7 activity, the loss of the mitochondrial membrane potential, and the degradation of nuclear DNA. Collectively, our results demonstrated that pyrazolo[3,4-d]pyrimidine derivatives inhibit cancer cell proliferation by inducing apoptosis and, thus, have the potential to be further explored for anticancer properties.

To develop novel simultaneous inhibition of PLK1 and BRD4 bromodomain by a single molecule, three series of novel pteridinone derivatives were designed, synthesized and evaluated for their biological activity. Most compounds exhibited moderate to excellent cytotoxic activity against A549, HCT116, PC-3 and MCF-7 cell lines. The most promising compoundIII(4)showed high antiproliferative effects on four cell lines with IC(50)values of 1.27 mu M, 1.36 mu M, 3.85 mu M and 4.06 mu M, respectively. The enzymatic assay identifiedIII(4)as a potent PLK1 and BRD4 dual inhibitor with % inhibition values of 96.6 and 59.1, respectively. Furthermore, to clarify the anticancer mechanism of the target compounds, explorations in the bioactivity were conducted. The results showed that compoundIII(4)obviously inhibited the proliferation of HCT-116 cell lines, induced a great decrease in the mitochondrial membrane potential leading to apoptosis of cancer cells, suppressed the migration of tumor cells, and arrested the S phase of HCT116 cells.

An article Abscisic acid and stress induced by salt: Effect on the phenylpropanoid, L-ascorbic acid and abscisic acid metabolism of strawberry fruits WOS:000536123200021 published article about FRAGARIA-X-ANANASSA; PHENYLALANINE AMMONIA-LYASE; TIME-QUANTITATIVE PCR; DIFFERENT CULTIVARS; GENE-EXPRESSION; DROUGHT STRESS; TOLERANCE; PROLINE; PLANT; MECHANISMS in [Crizel, R.

Strawberry is one of the most popular fruits because of its sensorial and functional properties. However, strawberry crop is sensitive to salt stress conditions. Despite plants have plasticity, high salt concentrations induce molecular, biochemical, and physiological responses in plants. There is evidence that the abscisic acid (ABA) hormone acts as a signaling molecule under stress conditions; however, the molecular mechanisms involved in the synthesis and homeostasis of ABA and in the induction of phytochemical antioxidant compounds under stress conditions remain unclear. In this study, the effect of stress induced by NaCl (salt stress – SS), with or without the simultaneous application of ABA, on the ABA, phenylpropanoids and L-ascorbic acid (AsA) metabolisms were evaluated. The physiological aspects (Na, Cl and proline concentration, photosynthetic variables) were also studied. The results showed that salt stress increases the Na and Cl content in the leaves, affects photosynthetic variables and triggers the production of proline, pelargonidin-3-O-glucoside, total phenolic compounds and AsA content, alongside the upregulation of several genes from the phenylpropanoid and flavonoid pathways. These effects were accompanied by the induction of compounds and transcripts related to ABA biosynthesis, conjugation and catabolism. Otherwise, the exogenous application of ABA in salt stressed plants promotes a shift in gene expression and metabolism to mitigate the stress. Therefore, salt stress affects the metabolism of ABA, phenylpropanoids and AsA in strawberry increasing phytochemical composition which is strongly associated with an ABA-dependent mechanism.

A facile, rapid one-step green strategy is established here to prepare the l-Histidine (His) capped silver nanoparticles (His-AgNPs) using microwave irradiation conditions performed for optimal duration of 5 min. For the prepared His-AgNPs have been characterized by X-ray powder diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), high-resolution scanning electron microscopy (HR-SEM), Zeta potential measurements and high-resolution transmission electron microscopy (HR-TEM), Energy dispersive X-ray spectroscopy (EDX) and UV-Vis spectroscopy techniques also. The HR-SEM images have exposed that flake-like internal structure formation of His-AgNPs with sort nanometer-sized spherical shape morphology has attained. As well, studies prove that, the antibacterial activities of synthesized His-AgNPs had a significant performance against various G(+) and G(-) bacteria. Then, the photocatalytic actions of His-AgNPs seem to contain sustaining degradation of MB and MO aqueous dyes under visible light exposure. Overall, the 98% of cationic MB dye degraded within 40 min and 97% anionic MO dye degraded within 100 min of photocatalytic irradiation. The probable mechanism for the improved photocatalytic assets of the His-AgNPs is also discussed. Hence, this study validated a simple and economical approach to synthesize His-AgNPs that are potential candidates for various highly useful industrial and packaging applications.
