Amaike, Kazuma;Oshima, Tsuyoshi;Skoulding, Nicola Stephanie;Toyama, Yoshifumi;Hirota, Tsuyoshi;Itami, Kenichiro research published 《 Small Molecules Modulating Mammalian Biological Clocks: Exciting New Opportunities for Synthetic Chemistry》, the research content is summarized as follows. The circadian clock is an intrinsic time-keeping system that controls daily rhythms in almost all living organisms on the earth. Daily rhythms are observed in various life phenomena, such as sleep-wake cycles, body temperature, blood pressure, and hormone secretion in animals, and stomatal movements and photosynthetic activity in plants. Therefore, controlling the circadian clock in a precise manner will make significant contributions in the elucidation of their mol. mechanisms, as well as to medicine and agriculture. Genetic and mol. biol. studies have made substantial progress in understanding of mol. clock mechanisms. For further investigation of the basic mechanisms as well as for therapeutic applications, small-mol. compounds will provide unique opportunities. In this perspective, we highlight chem. biol. approaches toward mammalian circadian clock modulation by using small synthetic mols.

Amiri Rudbari, Hadi;Saadati, Arezoo;Aryaeifar, Mahnaz;Blacque, Olivier;Cuevas-Vicario, Jose V.;Cabral, Rui;Raposo, Luis R.;Fernandes, Alexandra R. research published 《 Platinum(II) and Copper(II) complexes of asymmetric halogen-substituted [NN′O] ligands: Synthesis, characterization, structural investigations and antiproliferative activity》, the research content is summarized as follows. In order to better understand the effect of structure, halogen substitution, metal ions and ligand flexibility on antiproliferative activity, eight Cu(II) complexes and eight Pt(II) complexes were obtained of 2,4-X₁,X₂-6-((pyridine-2-ylmethylamino)methyl)phenol and 2,4-X₁,X₂-6-((pyridine-2-ylmethylamino)ethyl)phenol (where X is Cl, Br, or I) ligands. The compounds were characterized with various techniques, such as FT-IR, NMR, elemental anal. and single-crystal X-ray diffraction (SCXRD). The X-ray structures showed that ligand acts as a bidentate and tridentate donor in Cu(II) and Pt(II) complexes, resp. This difference in structures is due to the use or non-use of base in the preparation of complexes. Also, complexation of Cl₂-H₂L₁ with CuCl₂·2H₂O gives two different types of structures: polymer (Cl₂-H₂L₁-Cu^polymer) and dimer (Cl₂-H₂L₁-Cu^dimer), according to the crystal color. In addition, ¹H NMR spectrum for platinum complexes display two set of signals that can be attributed to the presence of two isomers in solution All complexes induced moderate to high reduction in A2780 and HCT116 cancer cell viability. However, only complexes bearing iodo- substituted in ligands exhibited significantly low cytotoxicity in normal fibroblasts when compared with cancer cell lines. The antiproliferative effect exhibited by I₂-H₂L₂-Cu complex in A2780 cell line was due to induction of cell death mechanisms, namely by apoptosis and autophagy. I₂-H₂L₂-Cu complex does not cause DNA cleavage but a slight delay in cell cycle was observed for the first 24 h of exposition. High cytotoxicity was related with the induction of intracellular ROS. This increase in intracellular ROS was not accompanied by destabilization of the mitochondrial membrane which is an indication that ROS are being triggered externally by I₂-H₂L₂-Cu complex and in agreement with an extrinsic apoptosis activation. I₂-H₂L₂-Cu complex has a pro-angiogenic effect, increasing the vascularization of the CAM in chicken embryos. This is also a very important characteristic in cancer treatment since the increased vascularization in tumors might facilitate the delivery of therapeutic drugs. Taken together, these results support the potential therapeutic of the I₂-H₂L₂-Cu complex.

Andrews, Mary Katherine;Liu, Xinyu;Gellman, Samuel H. research published 《 Tailoring Reaction Selectivity by Modulating a Catalytic Diad on a Foldamer Scaffold》, the research content is summarized as follows. Use of a tunable mol. scaffold to align a reactive diad for bifunctional catalysis can reveal relationships between functional group identity and reactivity that might otherwise be impossible to identify. Here we use an α/β-peptide helix to show that an aligned pair of primary amine groups is uniquely competent to catalyze crossed aldol condensations with an aryl aldehyde as the electrophile. Geometrically similar diads in which one amine group is secondary, or both are secondary, are good catalysts for other types of aldol condensations but not those involving an aryl aldehyde. Catalytic efficacy requires β-amino acid residues that are preorganized for helix formation via cyclic constraint. Conventional peptides (exclusively α-amino acid residues) that display the primary amine diad are poor catalysts, which highlights the critical role of the foldamer scaffold.

This process results in electron transfer from the donor to an acceptor molecule, such as oxygen or nitrogen. The pharmacokinetic properties of this compound are not well known; however, it has been demonstrated that it can be synthesized through a cross-coupling reaction with other aromatic compounds such as stemofuran., COA of Formula: C8H9BrO2
