Abstract
AbstractA new set of photoactivatable NADPH mimics bearing a thiourea linkage between a diarylbutadiene and an adenosine moiety functionalized by O-carboxymethyl groups has been designed and synthesized in a convergent strategy. These compounds display absorption and fluorescence emission maxima in DMSO (λmax,abs = 390 nm and λmax,em = 460 nm, respectively) consistent with the previously described analogues, with good fluorescence quantum yields (ΦF = 0.35–0.36), as well as two-photon absorption (σ2 = 10.1 GM at λmax,exc = 780 nm). These molecules could be useful photosensitive tools for biological studies, especially for cellular studies of nitric oxide synthases.

Abstract
Aiming at synthesis of dense 1,2,3-triazole polymers soluble in common organic solvents, a new 3-azido-1-propyne derivative, i.e., t-butyl 4-azido-5-hexynoate (tBuAH), was synthesized and polymerized by copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) and Huisgen cycloaddition (HC). CuAAC polymerization produced poly(tBuAH) composed of 1,4-disubstituted 1,2,3-triazole units (1,4-units), whereas HC polymerization gave poly(tBuAH) composed of 1,4- and 1,5-disubstituted 1,2,3-triazole units (1,4- and 1,5-units). In HC polymerization, the fraction of 1,4-unit (f1,4) decreased with the permittivity of solvent used. Differential scanning calorimetry data indicated that the melting point of poly(tBuAH) increased from 61 to 89 °C with increasing f1,4 from 0.38 to 1.0, indicative of higher crystallinity of poly(tBuAH) composed of 1,4-unit. Preliminary steady-state fluorescence study indicated that all the poly(tBuAH) samples of different f1,4 emitted weak but significant fluorescence in DMF. The maximum of fluorescence band shifted from ca. 350 to ca. 450 nm with varying the excitation wavelength from 300 to 400 nm.

Abstract
Hitherto unknown chromophoric nucleosides are reported. This novel set of visibly coloured dye-labeled 5'-nucleosides, including 1,2,4,5-tetrazine, dicyanomethylene-4H-pyran, benzophenoxazinone, 9,10-anthraquinone and azobenzene chromophores, were prepared mainly under Cu-catalyzed azide-alkyne cycloaddition (CuAAC). The design criteria are outlined. Several derivatives possess in supplement a fluorescence property. The absorption and fluorescence spectra of all coloured nucleosides were recorded to study their potential as visible-range probes. Such nucleodyes are of great interest for future competitive lateral flow test MIP-based strips.

Abstract
A new series of photoactivable NADPH mimics bearing one or two O-carboxymethyl groups on the adenosine moiety have been readily synthesized using click chemistry. These compounds display interesting one- or two-photon absorption properties. Their fluorescence emission wavelength and quantum yields (Φ) are dependent on the solvent polarity, with a red-shift in a more polar environment (λmax,em = 460-467 nm, Φ > 0.53 in DMSO, and λmax,em = 475-491 nm, Φ < 0.17 in Tris). These compounds show good binding affinity towards the constitutive nNOS and eNOS, confirming for the first time that the carboxymethyl group can be used as a surrogate of phosphate. Two-photon fluorescence imaging of nanotriggers in living cells showed that the presence of one carboxymethyl group (especially on the 3' position of the ribose) strongly favors the addressing of nanotriggers to eNOS in the cell context.

Abstract
The communesin alkaloids are a diverse family of Penicillium-derived alkaloids. Their caged-polycyclic structure and intriguing biological profiles have made these natural products attractive targets for total synthesis. Similarly, the ascidian-derived alkaloid, perophoramidine, is structurally related to the communesins and has also become a popular target for total synthesis. This review serves to summarize the many elegant approaches that have been developed to access the communesin alkaloids and perophoramidine. Likewise, strategies to access the communesin ring system are reviewed.

Abstract
A library of eighty one adenosine antibiotic analogs was prepared under the Pilot Scale Library Program of the NIH Roadmap initiative from 5'-amino-5'-deoxy-2',3'-O-isopropylidene-adenosine 3. Diverse aldehyde, sulfonyl chloride and carboxylic acid reactant sets were condensed to 3, in solution-phase fashion, leading after acid-mediated hydrolysis to the targeted compounds in good yields and high purity. No marked antituberculosis or anticancer activity was noted on preliminary cellular testing, but these nucleoside analogs should be useful candidates for other types of biological activity.

Abstract
There is a well documented need to replenish the antibiotic pipeline with new agents to combat the rise of drug resistant bacteria. One strategy to combat resistance is to discover new chemical classes immune to current resistance mechanisms that inhibit essential metabolic enzymes. Many of the obvious drug targets that have no homologous isozyme in the human host have now been investigated. Bacterial drug targets that have a closely related human homologue represent a new frontier in antibiotic discovery. However, to avoid potential toxicity to the host, these inhibitors must have very high selectivity for the bacterial enzyme over the human homolog. We have demonstrated that the essential enzyme biotin protein ligase (BPL) from the clinically important pathogen Staphylococcus aureus could be selectively inhibited. Linking biotin to adenosine via a 1,2,3 triazole yielded the first BPL inhibitor selective for S. aureus BPL over the human equivalent. The synthesis of new biotin 1,2,3-triazole analogues using click chemistry yielded our most potent structure (K(i) 90 nM) with a >1100-fold selectivity for the S. aureus BPL over the human homologue. X-ray crystallography confirmed the mechanism of inhibitor binding. Importantly, the inhibitor showed cytotoxicity against S. aureus but not cultured mammalian cells. The biotin 1,2,3-triazole provides a novel pharmacophore for future medicinal chemistry programs to develop this new antibiotic class.

Abstract
The synthesis of a library of nucleoside triphosphate mimetics is described where the Mg(2+) chelated triphosphate sidechain is replaced by an uncharged methylene-triazole linked monosaccharide sidechain. The compounds have been evaluated as inhibitors of Bacillus anthracis pantothenate kinase and a competitive inhibitor has been identified with a K(i) that is 3-fold lower than the K(m) value of ATP.

Abstract
5'-Aziridinoadenylates of the form 1 and a related nitrogen mustard variant have been constructed using a novel variation of the Mitsunobu reaction. Such molecules allow conversion of biological methyltransferases into nucleoside transferases, thus providing powerful tools for investigating S-adenosyl-l-methionine (SAM)-dependent methylation. We present here a highly effective synthesis of such molecules that is amenable to aziridine diversification as well as elaboration of the base moiety so as to afford "bumped" cofactor mimics compatible with "hole"-bearing mutant proteins.

Abstract
8-Azido-5'-aziridino-5'-deoxyadenosine (6), a novel cofactor mimic, was synthesized in nine steps from commercially available 2',3'-isopropylideneadenosine in approximately 4% overall yield. Crucial to this success was a very unorthodox phthalimide cleavage procedure, C8 azidation prior to aziridination and late stage alkylation of the 5' amino group with iodoethanol necessitated by the high degree of lability endowed by the aryl azide moiety. Aziridine 6 is envisioned as a useful biochemical tool by which to probe DNA and protein methylation patterns.
