In addition to the well-known strategies of antibiotic resistance and biofilm formation, bacterial populations possess an additional survival strategy to endure hostile environments or antibiotic exposure. A small fraction of transiently antibiotic-tolerant phenotypical variants, called persister cells, is capable of surviving treatment with high doses of antibiotics. When antibiotic pressure drops, persisters that switch back to a normal phenotype can resume growth, ensuring survival of the bacterial population. Persister cells have been identified in every major pathogen, contribute to the antibiotic tolerance observed in biofilms, and are responsible for the recalcitrant nature of chronic infections. Also, evidence is accumulating that persister cells can contribute to the emergence of antibiotic resistance. Consequently, effective treatment of persister cells could greatly improve patient outcome. The small number of persisters and the redundancy in mechanisms of persister formation impede target-based development of anti-persister therapies. Nonetheless, the armory of anti-persister molecules is increasing. This review presents a comprehensive overview of anti-persister molecules and strategies described in literature to date and offers perspectives on potential anti-persistence targets and methods for the development of future therapies. Furthermore, we highlight in vivo model systems for pre-clinical testing and summarize ongoing clinical trials of candidate anti-persister therapeutics.

Friedel-Crafts alylation of indole and its derivatives with a variety of electron-deficient alkenes catalyzed by Mg and Ca salts has been studied. The dependence of the results on the nature of the starting olefins, substituents on indole, and Michael acceptors, as well as on the composition of the Lewis acid is discussed. High yields of the addition products were achieved in the addition of indole to beta,gamma-unsaturated alpha-keto esters and coumarin derivatives, some nitroolefins, and arylidenemalonates. Reactions involving arylidenemalonates were found to be the most versatile and smooth, the best yields reached 92%. Among the Mg and Ca salts tested, magnesium iodide (MgI 2) proved to be the most appropriate catalyst in the addition to various unsaturated carbonyl compounds, while calcium triflimide [Ca(NTf 2) 2 ] efficiently catalyzed the addition to nitroolefins.

A series of 5-substituted 2-pyrrolidinones was synthesized through a one-pot ruthenium alkylidene-catalyzed tandem RCM/isomerization/nucleophilic addition sequence. The intermediates resulting from RCM/isomerization showed reactivity toward electrophiles in aldol condensation reactions which provided a new entry for the total synthesis of the antileukemic natural product violacein.

Efforts to develop ligands that distinguish between clinically relevant 5-HT2A and 5-HT2C serotonin receptor subtypes have been challenging, because their sequences have high homology. Previous studies reported that a novel aplysinopsin belonging to a chemical class of natural products isolated from a marine sponge was selective for the 5-HT2C over the 5-HT2A receptor subtype. Our goal was to explore the 5-HT2A/2C receptor structure-affinity relationships of derivatives based on the aplysinopsin natural product pharmacophore. Twenty aplysinopsin derivatives were synthesized, purified and tested for their affinities for cloned human serotonin 5-HT1A, 5-HT2A, and 5-HT2C receptor subtypes. Four compounds in this series had >30-fold selectivity for 5-HT2A or 5-HT2C receptors. The compound (E)-5-((5,6-dichloro-1H-indol-3-yl)methylene)- 2-imino-1,3-dimethylimidazolidin-4-one (UNT-TWU-22, 16) had approximately 2100-fold selectivity for the serotonin 5-HT2C receptor subtype: an affinity for 5-HT2C equal to 46 nM and no detectable affinity for the 5-HT1A or 5-HT2A receptor subtypes. The two most important factors controlling 5-HT2A or 5-HT2C receptor subtype selectivity were the combined R1,R3-alkylation of the imidazolidinone ring and the type and number of halogens on the indole ring of the aplysinopsin pharmacophore.

Caulerpin (1a), a bis-indole alkaloid from the marine algal Caulerpa sp., was synthesized in three reaction steps with an overall yield of 11%. The caulerpin analogues (1b-1g) were prepared using the same synthetic pathway with overall yields between 3% and 8%. The key reaction involved a radical oxidative aromatic substitution involving xanthate (3) and 3-formylindole compounds (4a-4g). All bis-indole compounds synthesized were evaluated against the Mycobacterium tuberculosis strain H37Rv, and 1a was found to display excellent activity (IC50 0.24 muM).

A method for direct difluoromethylthiolation of Ar?H bonds is introduced. The stable and easy-to-handle HCF2SO2Na is reduced with (EtO)2P(O)H in the presence of TMSCl to generate HCF2S+ for the regioselective difluoromethylthiolation of aromatic compounds including indoles, pyrroles, and activated benzenes. This method is also applicable for the trifluoromethylthiolation with CF3SO2Na and the perfluoroalkylthiolation with RfSO2Na of arenes and heteroarenes. Reaction mechanisms associated with the metal-free electrophilic fluoroalkylthiolation reactions are also discussed. (Figure presented.).

For the synthesis of unsymmetrical acetylenes, a Sonogashira coupling-deprotection-Sonogashira coupling reaction sequence is often used. Removal of protecting groups requires harsh conditions or an excess of difficult to handle and expensive reagents. Herein, we disclose a novel catalytic method for the selective deprotection of trimethylsilylacetylenes in Sonogashira reaction. The reagent hexafluorosilicic acid, an inexpensive nontoxic compound, was used to promote the selective desilylation. This method enables the efficient synthesis of unsymmetric acetylenes with other silylated functional groups present. Further possibilities of the method were explored by synthesis of heterocycles.
