Natural Products as Sources of New Fungicides (I): Synthesis and Antifungal Activity of Acetophenone Derivatives Against Phytopathogenic Fungi

Several series of 45 acetophenone derivatives bearing various alkyl or benzyl substituents were conveniently synthesized and their structures characterized by 1H and 13C NMR spectroscopy, HRMS and single-crystal X-ray analysis. Their in vitro antifungal activities against a panel of phytopathogenic fungi were evaluated by mycelial growth rate assay. Of them, 12 derivatives (e.g., 3a-c, 4c and 4e) exhibited more potent antifungal effects on some phytopathogens than a commercial fungicide hymexazol as positive control. In particular, compound 3b with IC50 values of 10-19μg/mL was found to be the most active in this series and might be a potential lead structure for further optimization. The preliminary structure-activity relationship (SAR) studies of a series of acetophenones are also discussed. A series of acetophenone derivatives have been synthesized and tested for their antifungal activities. Of them 12 derivatives exhibited more potent antifungal effects on some phytopathogens than a positive control hymexazol. Especially, compound 3b (IC50=10-19μg/mL) was found to be the most active and might be a potential lead structure. The SAR of these acetophenones is also discussed.

3-Carboxamido-5-aryl-isoxazoles as new CB2 agonists for the treatment of colitis

Recent investigations showed that anandamide, the main endogenous ligand of CB1 and CB2 cannabinoid receptors, possesses analgesic, antidepressant and anti-inflammatory effects. In the perspective to treat inflammatory bowel disease (IBD), our approach was to develop new selective CB2 receptor agonists without psychotropic side effects associated to CB1 receptors. In this purpose, a new series of 3-carboxamido-5- aryl-isoxazoles, never described previously as CB2 receptor agonists, was designed, synthesized and evaluated for their biological activity. The pharmacological results have identified great selective CB2 agonists with in vivo anti-inflammatory activity in a DSS-induced acute colitis mouse model.

Discovery of α,γ-Diketo Acids as Potent Selective and Reversible Inhibitors of Hepatitis C Virus NS5b RNA-Dependent RNA Polymerase

α,γ-Diketo acids (DKA) were discovered from screening as selective and reversible inhibitors of hepatitis C virus NS5b RNA-dependent RNA polymerase. The diketo acid moiety proved essential for activity, while substitution on the γ position was necessary for selectivity and potency. Optimization led to the identification of a DKA inhibitor of NS5b polymerase with IC50 = 45 nM, one of the most potent HCV NS5b polymerase inhibitors reported.

Cyclic Nucleotide Phosphodiesterase Inhibition by Imidazopyridines: Analogues of Sulmazole and Isomazole as Inhibitors of the cGMP Specific Phosphodiesterase

The synthesis and phosphodiesterase (PDE) inhibitory profile of a series of imidazopyridines, including sulmazole and isomazole, on separated PDE isoenzymes are described.The results show that both sulmazole and isomazole are weak inhibitors of PDE III, and their inotropic activity is unlikely to be due to PDE III inhibition alone.Surprisingly, both compounds were found to be significant inhibitors of the cGMP specific isoenzyme, PDE V, and a series of simple 2-substituted phenylimidazopyridines have been made to investigate the SAR of PDE activity.This has been shown to be sensitive to chain length, polarity, and the nature of the heteroatom linking group.Potent PDE V inhibitors, many of which are also significant inhibitors of PDE IV, have been identified.

Photocyclization Reactions. Part 1. Synthesis of Dihydrobenzofuranols Using Photocyclization of 2-Alkoxybenzaldehydes, 2'-Alkoxyacetophenones, 2-Formylphenoxyacetic Acids and 2-Acetylphenoxyacetic Acids

Photocyclization reactions were carried out on 2-alkoxybenzaldehydes 1a-f, 2'-alkoxyacetophenones 2a-h, 2-formylphenoxyacetic acids 1i-l and 2-acetylphenoxyacetic acids 2i-m.Irradiation opf 1a-f and 2a-h in acetonitrile gave the corresponding dihydrobenzofuranols 3, 5 and dihydroisobenzofuranols 4, 6.Using carboxylic acids 1i-l, 2i-m as starting materials, decarboxylation occurred immediately to give the corresponding ethers 1a-d, 2a-e.Further irradiation of the solution afforded dihydrobenzofuranols 3,5 and dihydroisobenzofuranols 4, 6.Substituent effects on photocyclization and reaction pathways are discussed.
