A novel series of 7,8-dichlorobenzofuro[3,2-c]quinoline-6,9,10(5H)-triones was obtained regioselectively in good yields. The products were formed by the reactions of the 4-hydroxy-2(1H)-quinolinones with 3,4,5,6-tetrachloro-1,2-benzoquinone in tetrahydrofuran as the solvent. Infrared, nuclear magnetic resonance (two-dimensional nuclear magnetic resonance), mass spectra and elemental analysis were used to elucidate the structures of new compounds.

Alkenyl boronates add to Ir(pi-allyl) intermediates with high enantioselectivity. A 1,2-metalate shift forms a second C-C bond and sets a 1,3-stereochemical relationship. The three-component coupling provides tertiary boronic esters that can undergo multiple additional functionalizations. An extension to trisubstituted olefins sets three contiguous stereocenters.

A regioselective C-H functionalization/annulation reaction of N-sulfonyl amides and allylbenzenes through a palladium-catalyzed C(sp(2))-H allylation/aminopalladation/beta-H elimination/isomerization sequence has been reported. Various aryl and alkenyl carboxamides are found to be efficient substrates to construct isoquinolinones and pyridinones in up to 96% yield. Using ambient air as the terminal oxidant is another advantage regarding environmental friendliness and operational simplicity.

A straightforward synthesis of original 1,6-diazabicyclo[4.3.0]nonane-2,7-diones was achieved through a DBU-organocatalyzed multicomponent Knoevenagel-aza-Michael-Cyclocondensation reaction which takes advantage of an unprecedented highly regio- and diastereoselective conjugate addition of pyridazinones to alkylidene Meldrum’s acid intermediates. The key reactive intermediates of this complex process were analyzed by means of electrospray ionization mass spectrometry coupled to ion mobility spectrometry, allowing us to validate the proposed mechanism.

A series of new 2-arylbenzothiazole derivatives (4, 5, 6a-j, 7a-i and 8a,b) was synthesized and tested for their antimicrobial activity against different Gram-positive, Gram-negative bacteria and yeast using ciprofloxacin and fluconazole as positive controls for the antibacterial and antifungal activities, respectively. The target compounds showed stronger inhibitory activity against Gram-negative than Gram-positive bacteria. The minimum inhibitory concentration (MIC) values were determined for those compounds showed zone of inhibition >= 13 mm. Based on the MIC values for the tested compounds against E. coli, compounds (4, 5, 6c, 6d, 6g, 6i, 6j, 7b, 7c, 7g and 8a) were selected and tested for their E. coli gyrase inhibitory activity. The tested compounds showed moderate inhibitory activity against E. coli gyrase. Compounds 5, 6c, 6i, 6j and 7b displayed high inhibitory activity against E. coli gyrase with IC50 values below 10 mu M, however, they were less active than ciprofloxacin (E. coli gyrase IC50 = 1.14 mu M). The p-hydroxy-m-methoxy benzothiazole analogue 6c was the most active tested compound (E. coli gyrase IC50 = 4.85 mu M). Quantitative structure-activity relationship (QSAR) study was also implemented for the newly synthesized compounds. The QSAR study indicated that the structural feature that governs the anti-microbial activity for the newly synthesized benzothiazole derivatives is their structural hydrophilic-lipophilic balance what agrees with the chemical intuition where this balance governs their cellular absorption and so their antimicrobial activity. Molecular docking showed that the newly synthesized compounds possess the required structural feature for E. coli gyrase B inhibition through interaction with the key amino acids Asp73 and Gly77.

A novel synthetic strategy toward N-acyl sulfamates was developed. Interestingly, fluorosulfates, a new emerging class of electrophiles, were used to construct the sulfamate core. This precludes handling of chlorosulfonyl isocyanate and sulfamoyl chloride. In combination with amides, a wide and diverse set of N-acyl sulfamates was synthesized, including functionalized bioactive compounds. Furthermore, initial results showed that this method is also amenable to access N-thioacyl sulfamates.

Androgen-deprivation therapy (ADT) is only a palliative measure, and prostate cancer invariably recurs in a lethal, castration-resistant form (CRPC). Prostate cancer resists ADT by metabolizing weak, adrenal androgens to growth-promoting 5 alpha-dihydrotestosterone (DHT), the preferred ligand for the androgen receptor (AR). Developing small-molecule inhibitors for the final steps in androgen metabolic pathways that utilize 17-oxidoreductases required probes that possess fluorescent groups at C-3 and intact, naturally occurring functionality at C-17. Application of the Pictet-Spengler condensation to substituted 4-(2-aminoethyl)coumarins and 5 alpha-androstane-3-ones furnished spirocyclic, fluorescent androgens at the desired C-3 position. Condensations required the presence of activating C-7 amino orN,N-dialkylamino groups in the 4-(2-aminoethyl)coumarin component of these condensation reactions. Successful Pictet-Spengler condensation, for example, of DHT with 9-(2-aminoethyl)-2,3,6,7-tetrahydro-1H,5H,11H-pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-11-one led to a spirocyclic androgen, (3R,5S,10S,13S,17S)-17-hydroxy-10,13-dimethyl-1,2,2 ‘,3 ‘,4,5,6,7,8,8 ‘,9,9 ‘,10,11,12,12 ‘,13,13 ‘,14,15,16,17-docosahydro-7 ‘ H,11 ‘ H-spiro-[cyclopenta[a]phenanthrene-3,4 ‘-pyrido[3,2,1-ij]pyrido[4 ‘,3 ‘:4,5]pyrano[2,3-f]quinolin]-5 ‘(1 ‘ H)-one. Computational modeling supported the surrogacy of the C-3 fluorescent DHT analog as a tool to study 17-oxidoreductases for intracrine, androgen metabolism.

We report here structural development of N-(4-phenoxyphenyl)benzamide derivatives as novel SPAK (STE20/ SPS1-related proline/alanine-rich kinase) inhibitors. Abnormal activation of the signal cascade of with-no-lysine kinase (WNK) with OSR1 (oxidative stress-responsive kinase 1)/SPAK and NCC (NaCl cotransporter) results in characteristic salt-sensitive hypertension, and therefore inhibitors of the WNK-OSR1/SPAK-NCC cascade are candidates for antihypertensive drugs. Based on the structure of lead compound 2, we examined the SAR of N-(4-phenoxyphenyl)benzamide derivatives, and developed compound 20l as a potent SPAK inhibitor. Compounds 20l is a promising candidate for a new class of antihypertensive drugs.

Intermediates in aromatic amino acid biosynthesis can serve as substrates for the synthesis of bioactive compounds. In this study we used two intermediates in the shikimate pathway of Escherichia coli, chorismate and anthranilate, to synthesize three bioactive compounds: 4-hydroxycoumarin (4-HC), 2,4-dihydroxyquinoline (DHQ), and 4-hydroxy-1-methyl-2(1H)-quinolone (NMQ). We introduced genes for the synthesis of salicylic acid from chorismate to supply the substrate for 4-HC and the gene encoding N-methyltransferase for the synthesis of N-methylanthranilate from anthranilate. Polyketide synthases and coenzyme (Co)A ligases were tested to determine the optimal combination of genes for the synthesis of each compound. We also tested several constructs and identified the best one for increasing levels of endogenous substrates for chorismate, anthranilate, and malonyl-CoA. With the use of these strategies, 255.4 mg/L 4-HC, 753.7 mg/L DHQ, and 17.5 mg/L NMQwere synthesized. This work provides a basis for the synthesis of diverse coumarin and quinoline derivatives with potential medical applications.
