Efficient synthesis of some new antiproliferative N-fused indoles and isoquinolines via 1,3-dipolar cycloaddition reaction in an ionic liquid

Syntheses of some new pyrrolo-fused pyrrolo[1,2-a] indole derivatives have been achieved by combining N-allyl-indole-2-carbaldehyde with a variety of N-alkyl-glycine esters as well as tetrahydroisoquinolines in an ionic liquid, triethylammonium acetate (TEAA), a recyclable reaction medium, via intramolecular [3+2] cycloaddition reaction. This new method is highly efficient, and the ionic liquid employed is recyclable. The stereochemistry of all the compounds was confirmed by 2D NMR NOESY and in some cases single crystal X-ray diffraction data. The in vitro screening of all new candidates against various bacterial strains and representative human solid tumor cell lines, A549 (lung), HeLa (cervix), SW1573 (lung), T-47D (breast) and WiDr (colon), revealed that many of them have good antibacterial, antifungal and antitubercular and antiproliferative activities.

Synthesis and in-vitro antimycobacterial evaluation of 1-(cyclopropyl/2,4- difluorophenyl/tert-butyl)-1,4-dihydro-8-methyl-6-nitro-4-oxo-7-(substituted secondary amino)quinoline-3-carboxylic acids

Fifty one newer -(cyclopropyl/2,4-difluorophenyl/tert-butyl)-1,4-dihydro-8- methyl-6-nitro-4-oxo-7-(substituted secondary amino)quinoline-3-carboxylic acids were synthesized from 1,3-dichloro-2-methylbenzene and evaluated for in-vitro antimycobacterial activities against Mycobacterium tuberculosis H37Rv (MTB), multi-drug resistant Mycobacterium tuberculosis (MDR-TB), and Mycobacte-rium smegmatis (MC2). Among the synthesized compounds, 1-cyclopropyl-1,4-dihydro-7-(3,4-dihy-dro-6,7-dimethoxyisoquinolin-2(1H)-yl) -8-methyl-6-nitro-4-oxoquinoline-3-carboxylic acid 9p was found to be the most active compound in vitro with a MIC value of 0.39 M against MTB.

Conjugate additions of sulfur-stabilized anions to unsaturated lactams. Synthesis of polyfunctionalized benzo[a]quinolizinone systems

Conjugate addition reactions of sulfur-stabilized nucleophiles to the delta-lactam unit of tetrahydrobenzo[a]benzoquinolizines have been studied. The stereochemical outcome of the conjugate addition reaction depends on the nature of the substituent at the angular position, thus 2,11b-cis or 2,11b-trans diastereomers could be obtained selectively. The tandem conjugate addition-alkylation also takes place in good yields and with high diastereoselectivity. The polyfunctionalized hexahydrobenzo[a]quinolizinone systems obtained could be further elaborated toward emetine-like structures.

Concise syntheses of (¡À)-protoemetinol and related alkaloids using radical cyclisation

Both (¡À)-protoemetinol, its 3-epi-isomer and (¡À)-3-desmethyl protoemetinol have been prepared in five linear steps from a dihydroisoquinoline using a 6-exo-trig cyclisation of a vinyl radical in the key step. This novel and particularly short route has potential application in the synthesis of Alangium and Mitragyna alkaloids.

Mechanistic studies on the catalytic asymmetric mannich-type reaction with dihydroisoquinolines and development of oxidative mannich-type reactions starting from tetrahydroisoquinolines

(Chemical Equation Presented) Detailed mechanistic studies on our recently reported asymmetric addition reactions of malonates to dihydroisoquinolines (DHIQs) catalyzed by chiral Pd(II) complexes were carried out. It was found that an N,O-acetal was generated in situ by the reaction of DHIQ with (Boc) 2O, and cooperative action of the Pd(II) complex as an acid-base catalyst allowed the formation of a chiral Pd enolate and a reactive iminium ion via alpha-fragmentation. The iminium ion was also accessible via oxidation with DDQ as an oxidant, and a catalytic asymmetric oxidative Mannich-type reaction was achieved with tetrahydroisoquinolines (THIQs) as starting materials. This oxidation protocol was applicable to N-acryloyl-protected THIQs, allowing the efficient synthesis of optically active tetrahydrobenzo[a] quinolizidine derivatives via intramolecular Michael reaction.

In vivo bioconversion of tetrahydroisoquinoline by recombinant coclaurine N-methyltransferase

Coclaurine N-methyltransferase from Coptis japonica catalyzes the N-methylation of coclaurine as well as simple tetrahydroisoquinoline. We examined the possibility of converting 6,7-dimethoxy-1,2,3,4- tetrahydroisoquinoline into its N-methylated product using transgenic Escherichia coli, which expressed recombinant coclaurine N-methyltransferase, without the addition of a methyl-group donor. Transgenic E. coli successfully N-methylated the substrate added to the medium and excreted the product. Limitation of bioconversion by the supply of methyl-group donor is discussed.

Novel spirobicyclic artemisinin analogues (artemalogues): Synthesis and antitumor activities

The sesquiterpene lactone framework of artemisinin was used as a drug repositioning prototype for the development of novel antitumor drugs. Several series of novel artemisinin analogues (artemalogues) were designed and synthesized through 1,3-dipolar cycloaddition of artemisitene with nitrile oxides or nitrones. The isoxazolidine-containing spirobicyclic artemalogue 11b turns out to be the most potent with low micromolar IC50 values against all three tumor cells, which were at least 4-to 14-fold more potent than the parent artemisinin.

99mTc-Cyclopentadienyl Tricarbonyl Chelate-Labeled Compounds as Selective Sigma-2 Receptor Ligands for Tumor Imaging

We have designed and synthesized a series of cyclopentadienyl tricarbonyl rhenium complexes containing a 5,6-dimethoxyisoindoline or a 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline pharmacophore as sigma2 receptor ligands. Rhenium compound 20a possessed low nanomolar sigma2 receptor affinity (Ki = 2.97 nM) and moderate subtype selectivity (10-fold). Moreover, it showed high selectivity toward vesicular acetylcholine transporter (2374-fold), dopamine D2L receptor, NMDA receptor, opiate receptor, dopamine transporter, norepinephrine transporter, and serotonin transporter. Its corresponding radiotracer [99mTc]20b showed high uptake in a time- and dose-dependent manner in DU145 prostate cells and C6 glioma cells. In addition, this tracer exhibited high tumor uptake (5.92% ID/g at 240 min) and high tumor/blood and tumor/muscle ratios (21 and 16 at 240 min, respectively) as well as specific binding to sigma receptors in nude mice bearing C6 glioma xenografts. Small animal SPECT/CT imaging of [99mTc]20b in the C6 glioma xenograft model demonstrated a clear visualization of the tumor at 180 min after injection.
