- Aromatic Spiranes, XIV: Syntheses of 2,2'-Spirobi-(s-hydrindacene) and its precursors
-
The title compound 35 was prepared by catalytic reduction of the diones 29a and 11a. 29a was synthesized by systematic anellation of fivemembered rings to the positions 5,6 and 5',6', resp., of 2,2'-spirobiindane.The preparation of 11a was achieved by Friedel-Crafts cyclisation of bis-(5-indanylmethyl)-malonic acid. s-Hydrindacene-1-one 5a was prepared as a precursor for the synthesis of 11a (see forthcoming publication) and its derivates as models for corresponding anellation and substitution reactions. - Keywords: s-Hydrindacene-1-one and derivates; Mono- and bisanellation; 2,2'-Spirobiindane; 1H-nmr spectra

- Discovery of N-Cyano-sulfoximineurea Derivatives as Potent and Orally Bioavailable NLRP3 Inflammasome Inhibitors
-
NLRP3 inflammasome mediated release of interleukin-1β (IL-1β) has been implicated in various diseases. In this study, rationally designed mimics of sulfonylurea moiety were investigated as NLRP3 inhibitors. Our results culminated into discovery of series of unprecedented N-cyano sulfoximineurea derivatives as potent NLRP3 inflammasome inhibitors. Compound 15 (IC50 = 7 nM) and analogues were found to be highly potent and selective NLRP3 inflammasome inhibitor with good pharmacokinetic profile. These effects translate in vivo, as 15, 29, and 34 significantly inhibit NLRP3 dependent IL-1β secretion in mice.

- Identification, Synthesis, and Biological Evaluation of the Major Human Metabolite of NLRP3 Inflammasome Inhibitor MCC950
-
MCC950 is an orally bioavailable small molecule inhibitor of the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome that exhibits remarkable activity in multiple models of inflammatory disease. Incubation of MCC950 with human liver microsomes, and subsequent analysis by HPLC-MS/MS, revealed a major metabolite, where hydroxylation of MCC950 had occurred on the 1,2,3,5,6,7-hexahydro-s-indacene moiety. Three possible regioisomers were synthesized, and coelution using HPLC-MS/MS confirmed the structure of the metabolite. Further synthesis of individual enantiomers and coelution studies using a chiral column in HPLC-MS/MS showed the metabolite was R-(+)- N-((1-hydroxy-1,2,3,5,6,7-hexahydro-s-indacen-4-yl)carbamoyl)-4-(2-hydroxypropan-2-yl)furan-2-sulfonamide (2a). Incubation of MCC950 with a panel of cytochrome P450 enzymes showed P450s 2A6, 2C9, 2C18, 2C19, 2J2, and 3A4 catalyze the formation of the major metabolite 2a, with a lower level of activity shown by P450s 1A2 and 2B6. All of the synthesized compounds were tested for inhibition of NLRP3-induced production of the pro-inflammatory cytokine IL-1β from human monocyte derived macrophages. The identified metabolite 2a was 170-fold less potent than MCC950, while one regioisomer had nanomolar inhibitory activity. These findings also give first insight into the SAR of the hexahydroindacene moiety.

- Functionalization of styrenes by copper-catalyzed borylation/ ortho-cyanation and silver-catalyzed annulation processes
-
An efficient two-step method for the assembly of indanone derivatives starting from a simple vinyl arene has been developed. The sequence first involves addition of bis(pinacolato)diboron (B2pin2) and N-cyano-N-phenyl-p-methylbenzenesulfonamide (NCTS) to a broad range of styrenes by utilizing IMesCuCl as catalyst. This step simultaneously accomplishes hydroboration of the alkene and ortho cyanation of the benzene unit. The products thus obtained are further functionalized by a AgNO3/Selectfluor-mediated coupling of the BPin and cyano functionalities to annulate a new five-membered ring. This combined two-step sequence provides a versatile method for the site-selective derivatization of a broad range of vinyl arene substrates. A Cu and Ag sequence: The bis-functionalization of styrenes is accomplished through a copper-catalyzed process that enables hydroboration of the alkene and regioselective ortho cyanation of the arene. The resulting adducts are converted, by a radical cyclization process, into a cyclopentanone unit fused to the original aromatic ring. Together, these methods allow efficient cyclopentannulation of a broad range of styrene derivatives.

- Novel synthesis of 1-(1,2,3,5,6,7-hexahydro-s-indacen-4-yl)-3-[4-(1-hydroxy-1-methyl-ethyl) furan-2-sulfonyl]urea, An anti-inflammatory agent
-
A novel synthesis of the anti-inflammatory agent 1-(1,2,3,5,6,7-hexahydro-s-indacen-4-yl)-3-[4-(1-hydroxy-1-methyl-ethyl)- furan-2-sulfonyl]urea 1 is described. Sulfonamide 5 was prepared starting from ethyl 3-furoate 2. Key steps were a one-pot sulfonylation with chlorosulfonic acid in methylene chloride followed by pyridinium salt formation and reaction with phosphorus pentachloride to provide ethyl 2-(chlorosulfonyl)-4-furoate 7. This sulfonyl chloride was treated with ammonium bicarbonate to form sulfonamide 8, followed by treatment with excess methyl magnesium chloride to provide 4-(1-hydroxy-1-methyl-ethyl)-furan-2-sulfonamide 5. 4-Isocyanato-1,2,3,5,6,7-hexahydro-s-indacene 16 was prepared from indan in five steps. The formation of the desired sulfonyl urea was carried out both with the isolated isocyanate 16 and via an in situ method.

- Electron Paramagnetic Resonance Spectra of the Radical Cations of Some Benzocyclobutenes, Benzocyclopentenes and Benzocyclohexenes

1,2,4,5-Tetrahydrobenzodicyclobutene, 1,2,3,5,6,7-hexahydrobenzodicyclopentene and 1,2,3,4,6,7,8,9-octahydrobenzodicyclohexene, and their dimethyl derivatives, and tetramethylbenzocyclo-butene, -pentene and -hexene have been prepared.All except the first compound have been oxidised to their corresponding radical cations, and the EPR spectra have been analysed by assigning McConnell-type Q-values to the substituents in the benzene ring.It is suggested that the ordering of the orbital energy levels (ΨA above ΨS) in 3,6-dimethylbenzobiscyclobutene and -pentene is a manifestation of the Mills-Nixon effect, and results from rehybridisation of the strained molecular framework.In the radical cations of 5,10-dimethyl-1,2,3,4,6,7,8,9-octahydrobenzodicyclohexene and 5,6,7,8-tetramethyl-1,2,3,4-tetrahydrobenzocyclohexene the total unpaired electron density, as implied by the McConnell type of relationship, appears to be less than unity.Various possible causes of this are examined.
