Convenient synthesis of novel 5-substituted 3-methylisoxazole-4- sulfonamides

A number of novel sulfonamide derivatives of 5-substituted-3- methylisoxazole were synthesized and characterized, starting from 3,5-dimethylisoxazole. Key steps include the generation of 3,5- dimethylisoxazole-4-sulfonamides followed by their reactions with N-(dimethoxymethyl)-N,N-dimethylamine or various aromatic and heteroaromatic aldehydes. As a result, a series of novel aryl/heteroaryl- and aminovinylsubstituted derivatives of the isoxazole heterocycle were obtained. The scope and limitations of the developed approach are discussed.

Convergent catalytic asymmetric synthesis of camptothecin analog GI147211C

The topoisomerase I inhibitor GI147211C (4) was discovered at Glaxo Wellcome and shown to have promising anti-cancer properties. In order to fully assess the clinical potential of 4, an improved synthesis of the drug substance was required. Herein is described a convergent catalytic asymmetric synthesis of 4 which utilizes as key steps, two Heck reactions, a Sharpless asymmetric dihydroxylation reaction, and a Mitsunobu reaction. A 2-chloroquinoline is shown to be a viable substrate for the final Heck reaction to generate the camptothecin nucleus.

Anti-biofilm effect of novel thiazole acid analogs against Pseudomonas aeruginosa through IQS pathways

IQS has been proven to be a new quorum sensing (QS) system against bacterial biofilm formation, which is activated in the common phosphate-limiting environment of infected tissues taking over the central las system. Up to now, numerous biofilm inhibitors which function by affecting traditional QS system have been reported. However, no compound has been reported to exert anti-biofilm activity through IQS system. Herein, various novel IQS derivatives were synthesized by the reaction of thiazole-4-carboxylic acid with different linear alcohols (R-OH) or amines (R-NH2). IQS derivatives with four carbon chain length of R group were found to present the best biofilm inhibition activity. Compound B-11 as the model molecule was observed to inhibit biofilm formation only under phosphate-limiting condition, and increase in B-11 concentration significantly reduced the expression of rhlA-gfp and pqsA-gfp, but lasB-gfp. Moreover, B-11 reduced production of virulence factors of rhamnolipid and pyocyanin under phosphate limitation. These observations indicated that the synthesized compounds possessed the anti-biofilm activity through IQS pathways rather than traditional QS pathways, which pave a path for future molecular design against bacterial biofilm formation.

Nickel-Catalyzed Esterification of Aliphatic Amides

Recent studies have demonstrated that amides can be used in nickel-catalyzed reactions that lead to cleavage of the amide C?N bond, with formation of a C?C or C?heteroatom bond. However, the general scope of these methodologies has been restricted to amides where the carbonyl is directly attached to an arene or heteroarene. We now report the nickel-catalyzed esterification of amides derived from aliphatic carboxylic acids. The transformation requires only a slight excess of the alcohol nucleophile and is tolerant of heterocycles, substrates with epimerizable stereocenters, and sterically congested coupling partners. Moreover, a series of amide competition experiments establish selectivity principles that will aid future synthetic design. These studies overcome a critical limitation of current Ni-catalyzed amide couplings and are expected to further stimulate the use of amides as synthetic building blocks in C?N bond cleavage processes.

Nanoscale synthesis and affinity ranking

Most drugs are developed through iterative rounds of chemical synthesis and biochemical testing to optimize the affinity of a particular compound for a protein target of therapeutic interest. This process is challenging because candidate molecules must be selected from a chemical space of more than 1060 drug-like possibilities 1, and a single reaction used to synthesize each molecule has more than 107 plausible permutations of catalysts, ligands, additives and other parameters 2 . The merger of a method for high-throughput chemical synthesis with a biochemical assay would facilitate the exploration of this enormous search space and streamline the hunt for new drugs and chemical probes. Miniaturized high-throughput chemical synthesis 3-7 has enabled rapid evaluation of reaction space, but so far the merger of such syntheses with bioassays has been achieved with only low-density reaction arrays, which analyse only a handful of analogues prepared under a single reaction condition 8-13 . High-density chemical synthesis approaches that have been coupled to bioassays, including on-bead 14, on-surface 15, on-DNA 16 and mass-encoding technologies 17, greatly reduce material requirements, but they require the covalent linkage of substrates to a potentially reactive support, must be performed under high dilution and must operate in a mixture format. These reaction attributes limit the application of transition-metal catalysts, which are easily poisoned by the many functional groups present in a complex mixture, and of transformations for which the kinetics require a high concentration of reactant. Here we couple high-throughput nanomole-scale synthesis with a label-free affinity-selection mass spectrometry bioassay. Each reaction is performed at a 0.1-molar concentration in a discrete well to enable transition-metal catalysis while consuming less than 0.05 milligrams of substrate per reaction. The affinity-selection mass spectrometry bioassay is then used to rank the affinity of the reaction products to target proteins, removing the need for time-intensive reaction purification. This method enables the primary synthesis and testing steps that are critical to the invention of protein inhibitors to be performed rapidly and with minimal consumption of starting materials.

Synthesis, crystal structures, insecticidal activities, and structure-activity relationships of novel N ?- Tert -Butyl- N ?-substituted-benzoyl- N -[di(octa)hydro]benzofuran{(2,3-dihydro)benzo[1, 3]([1,4])dioxine}carbohydrazide derivatives

Several series of novel N?-tert-butyl-N?-substituted-benzoyl-N- [di(octa)hydro]benzofuran{(2,3-dihydro)benzo[1,3]([1,4])dioxine}carbohydrazide derivatives Ia, Ib, IIa-IIg, IIIa, IIIb, and Va-Vc were designed and synthesized. Their structures were confirmed by 1H NMR spectra, HRMS, and X-ray single-crystal structures. The larvicidal activities against oriental armyworm, beet armyworm, diamond-back moth, and corn borer of these compounds were evaluated and contrasted with those of RH-2485, JS-118, and ANS-118. The larvicidal activities against oriental armyworm indicate that monosubstituent or multisubstituents and the substituting group position cannot promote increasing activities and that the cycle region in the general structure of IIa-IIg is much more sensitive to activity than that in the general structure of Ia and Ib. The space volume of the A ring in the structure of Va cannot be too large; if it is, the activity will be decreased significantly. Stomach toxicities against beet armyworm, diamond-back moth, and corn borer of compounds Ia, Ib and IIg indicate that benzoheterocyclic analogues of N-tert-butyl-N,N?- diacylhydrazines show significant selectivities to different lepidopterous pests.

TRPV1 modulators: Synthesis and in vitro evaluation of 1-heteroaryl piperidinecarboxamide and piperazinylurea derivatives

Abstract A series of new 1-heteroaryl piperidinecarboxamide and piperazinylurea derivatives was synthesized and evaluated as TRPV1 modulators in a Ca2+ channel assay in HEK-293 cells overexpressing the human recombinant TRPV1 channel. Structural variations in the putative key portions of the molecules afforded several compounds endowed with agonist and/or antagonist/desensitizing activity at low micromolar concentration. As promising examples from this series, the piperidine-3-carboxamide derivative 31 exerts agonist/desensitizing activity at low micromolar concentration, while piperazinylurea derivatives 39 and 41 act as antagonists with sub-micromolar potency.
