Chemical synthesis and biological evaluation of palmerolide A analogues

Molecular design and chemical synthesis of several palmerolide A analogues allowed the first structure activity relationships (SARs) of this newly discovered marine antitumor agent. From several analogues synthesized and tested (ent-1, 5-14, 21-26, 50, 51), compounds 25 (with a phenyl substituent on the side chain) and 51 (lacking the C-7 hydroxyl group) were the most interesting, exhibiting approximately a 10-fold increase in potency and equipotency, respectively, to the natural product. These findings point the way to more focused structure activity relationship studies.

Synthesis of strained complexes of arene d6 metals with benzoylthiourea and their spectral studies

Halide bridged arene d6 platinum group metal precursors on treatment with thiourea derivatives (L1 and L2) yielded a series of neutral mono-dentate complexes (1?8). In general complexes have been formulated as [(arene)M(L)?1(S)Cl2] where L = L1, M = Ru, arene = p-cymene 1; benzene 2; arene = Cp* M = Rh 3 and Ir 4; L = L2, M = Ru, p-cymene 5; benzene 6; arene = Cp* M = Rh 7 and Ir 8. Structural studies revealed that thiourea ligand coordinate to the metal in a mono-dentate fashion via S atom. Further treatment of mono-dentate complexes 1 and 5 with NaN3 in polar solvent resulted in the formation of highly strained ?2(N,S) azido complexes 9 and 10 whereas reaction of complex 7 yielded a six membered ring ?2(S,O) azido complex 11. Reaction of complex 9 with dimethylacetylene dicarboxylate (DMAD) and diethylacetylene dicarboxylate (DEAD) leads to the formation of nitrogen (N2) bound triazolato complexes 12 and 13 whereas reaction of complex 11 with the same yielded nitrogen (N1) bound triazolato complexes 14 and 15. However reaction of complex 10 with both DMAD and DEAD leads to decomposition of the products. All these complexes have been characterized by various spectroscopic techniques. The molecular structures of the representative complexes 1, 2, 3, 6, 7, 9, 11 and 12 have been determined by single crystal X-ray diffraction study.

Aminocyclopropanes as precursors of endoperoxides with antimalarial activity

This contribution describes the synthesis of several novel bicyclic alpha-amino endoperoxides, including CF3-substituted compounds, prepared by the aerobic electrochemical oxidation of a family of bicyclic aminocyclopropanes. These, in turn, are readily synthesised by a titanium-mediated intramolecular cyclopropanation process (Kulinkovich-de Meijere reaction), starting from N-alkenyl amides that contain a vic-disubstituted double bond, with high diastereoselectivity. An evaluation of the biological activities of several of the molecules produced, against the parasite Plasmodium falciparum, is also presented.

Escherichia coli allows efficient modular incorporation of newly isolated quinomycin biosynthetic enzyme into echinomycin biosynthetic pathway for rational design and synthesis of potent antibiotic unnatural natural product

Natural products display impressive activities against a wide range of targets, including viruses, microbes, and tumors. However, their clinical use is hampered frequently by their scarcity and undesirable toxicity. Not only can engineering Escherichia coli for plasmid-based pharmacophore biosynthesis offer alternative means of simple and easily scalable production of valuable yet hard-to-obtain compounds, but also carries a potential for providing a straightforward and efficient means of preparing natural product analogs. The quinomycin family of nonribosomal peptides, including echinomycin, triostin A, and SW-163s, are important secondary metabolites imparting antibiotic antitumor activity via DNA bisintercalation. Previously we have shown the production of echinomycin and triostin A in E. coli using our convenient and modular plasmid system to introduce these heterologous biosynthetic pathways into E. coli. However, we have yet to develop a novel biosynthetic pathway capable of producing bioactive unnatural natural products in E. coli. Here we report an identification of a new gene cluster responsible for the biosynthesis of SW-163s that involves previously unknown biosynthesis of (+)-(1S, 2S)-norcoronamic acid and generation of aliphatic side chains of various sizes via iterative methylation of an unactivated carbon center. Substituting an echinomycin biosynthetic gene with a gene from the newly identified SW-163 biosynthetic gene cluster, we were able to rationally re-engineer the plasmid-based echinomycin biosynthetic pathway for the production of a novel bioactive compound in E. coli.

Structural, physicochemical, and reactivity properties of an all-inorganic, highly active tetraruthenium homogeneous catalyst for water oxidation

Several key properties of the water oxidation catalyst Rb8K 2[{RuIV4O4(OH)2(H 2O)4}(gamma-SiW10O36) 2] and its mechanism of water oxidation are given. The one-electron oxidized analogue [{RuVRuIV3O 6(OH2)4}(gamma-SiW10O 36)2]11- has been prepared and thoroughly characterized. The voltammetric rest potentials, X-ray structures, elemental analysis, magnetism, and requirement of an oxidant (O2) indicate these two complexes contain [RuIV4O6] and [RuVRuIV3O6] cores, respectively. Voltammetry and potentiometric titrations establish the potentials of several couples of the catalyst in aqueous solution, and a speciation diagram (versus electrochemical potential) is calculated. The potentials depend on the nature and concentration of counterions. The catalyst exhibits four reversible couples spanning only ca. 0.5 V in the H2O/O2 potential region, keys to efficient water oxidation at low overpotential and consistent with DFT calculations showing very small energy differences between all adjacent frontier orbitals. The voltammetric potentials of the catalyst are evenly spaced (a Coulomb staircase), more consistent with bulk-like properties than molecular ones. Catalysis of water oxidation by [Ru(bpy)3]3+ has been examined in detail. There is a hyperbolic dependence of O2 yield on catalyst concentration in accord with competing water and ligand (bpy) oxidations. O2 yields, turnover numbers, and extensive kinetics data reveal several features and lead to a mechanism involving rapid oxidation of the catalyst in four one-electron steps followed by rate-limiting H2O oxidation/O2 evolution. Six spectroscopic, scattering, and chemical experiments indicate that the catalyst is stable in solution and under catalytic turnover conditions. However, it decomposes slowly in acidic aqueous solutions (pH < 1.5).

DNA Photocleavage by Non-innocent Ligand-Based Ru(II) Complexes

In this work, we demonstrate for the first time that [Ru(bpy)2(R-OQN)]+ complexes (bpy = 2,2?-bipyridine, R-OQN = 5-chloro-8-oxyquinolate or 5-bromo-8-oxyquinolate) are able to generate hydroxyl radicals and cleave DNA effectively upon visible light irradiation. The potent electron-donating ability of the R-OQN-based non-innocent ligands gives the complexes a high reducing capability, favoring the generation of superoxide anion radicals from which hydroxyl radicals may be generated. More interestingly, halogen substitution plays an important role. When the 5-Cl- or 5-Br-8-oxyquinolate ligand is replaced by 8-oxyquinolate or 5-CH3-8-oxyquinolate, the corresponding complexes lose their hydroxyl radical-generation and DNA photocleavage abilities. These findings open new applications for the non-innocent ligand-based Ru(II) complexes in the fields of biology and medicine, such as in photodynamic therapy (PDT).
