Synthesis of tetrahydro-1H,7H-benzo[ij]quinolizine-1,7-dione derivatives

Tetrahydro-1H,7H-benzo[ij]quinolizine-1,7-diones have been obtained by the cyclization of N-alkoxyphenyl-N-(2-carboxyethyl)-beta-alanines. Fission of the ester bond occurs on cyclization of N-(4-ethoxyphenyl)-N-(2-carboxyethyl)-beta-alanine, but the cyclization of the 3,4-dialkoxyphenyl derivative leads to the formation of 9-alkoxy-8-hydroxy-2,3,5,7-tetrahydro-1H,7H-benzo[ij]quinolizine-1,7-diones. The corresponding dioximes and diphenylhydrazones were obtained.

Quinoline-2,4-dicarboxylic acids: Synthesis and evaluation as inhibitors of the glutamate vesicular transport system

Twenty-six quinoline-2,4-dicarboxylic acids (QDC’s) were synthesized by a modified Doebner-von Miller pathway and tested as inhibitors against the glutamate vesicular transport (GVT) protein. The QDC’s were active as inhibitors with the most potent QDC’s found to contain halogens at the 6-/8-position, a hydroxyl at the 8-position, or a tethered aromatic moiety at the 6- or 7-position of the quinoline.

WB 4101-related compounds. 2. Role of the ethylene chain separating amine and phenoxy units on the affinity for alpha1-adrenoreceptor subtypes and 5-HT(1A) receptors

WB 4101 (1)-related benzodioxanes were synthesized by replacing the ethylene chain separating the amine and the phenoxy units of 1 with a cyclopentanol moiety, a feature of 6,7-dihydro-5-[[(cis-2-hydroxy-trans-3- phenoxycyclopentyl)amino]methyl]-2-methylbenzo[b]thiophen-4(5H)- one that was reported to display an intriguing selectivity profile at alpha1- adrenoreceptors. This synthesis strategy led to 4 out of 16 possible stereoisomers, which were isolated in the case of (-)-3, (+)-3, (-)-4, and (+)-4 and whose absolute configuration was assigned using a chiral building block for the synthesis of (-)-3 starting from (+)-(2R)-2,3-dihydro-1,4- benzodioxine-2-carboxylic acid ((+)-9) and (1S,2S,5S)-2-amino-5- phenoxycyclopentan-1-ol ((+)-10). The aim of this project was to further investigate whether it is possible to differentiate between these compounds with respect to their affinity for alpha1-adrenoreceptor subtypes and the affinity for 5-HT(1A) receptors, as 1 binds with high affinity at both receptor systems. The biological profiles of reported compounds at alpha1- adrenoreceptor subtypes were assessed by functional experiments in isolated rat vas deferens (alpha(1A)), spleen (alpha(1B)), and aorta (alpha(1D)) and by binding assays in CHO and HeLa cells membranes expressing the human cloned alpha1- adrenoreceptor subtypes and 5-HT(1A) receptors, respectively. Furthermore, the functional activity of (-)-3, (+)-3, (-)-4, and (+)-4 toward 5-HT(1A) receptors was evaluated by determining the induced stimulation of [35S]- GTPgammaS binding in cell membranes from HeLa cells transfected with human cloned 5-HT(1A) receptors. The configuration of the cyclopentane unit determined the affinity profile: a 1R configuration, as in (+)-3 and (-)-4, conferred higher affinity at alpha1-adrenoreceptors, whereas a 1S configuration, as in (-)-3 and (+)-4, produced higher affinity for 5-HT(1A) receptors. For the enantiomers (+)-4 and (-)-4 also a remarkable selectivity was achieved. Functionally, the stereoisomers displayed a similar alpha1- selectivity profile, that is alpha(1D) > alpha(1B) > alpha(1A), which is different from that exhibited by the reference compound 1. The epimers (-)-3 and (+)-4 proved to be agonists at the 5-HT(1A) receptors, with a potency comparable to that of 5-hydroxytryptamine.

Inhibitors for human glutaminyl cyclase by structure based design and bioisosteric replacement

The inhibition of human glutaminyl cyclase (hQC) has come into focus as a new potential approach for the treatment of Alzheimer’s disease. The hallmark of this principle is the prevention of the formation of Abeta 3,11(pE)-40,42, as these Abeta-species were shown to be of elevated neurotoxicity and likely to act as a seeding core leading to an accelerated formation of Abeta-oligomers and fibrils. Starting from 1-(3-(1H-imidazol-1- yl)propyl)-3-(3,4-dimethoxyphenyl)thiourea, bioisosteric replacements led to the development of new classes of inhibitors. The optimization of the metal-binding group was achieved by homology modeling and afforded a first insight into the probable binding mode of the inhibitors in the hQC active site. The efficacy assessment of the hQC inhibitors was performed in cell culture, directly monitoring the inhibition of Abeta3,11(pE)-40,42 formation. 2009 American Chemical Society.

Effect of O6-substituted guanine analogs on O6-methylguanine DNA-methyltransferase Expression and glioblastoma cells viability

Background: Glioblastoma multiforme (GBM) is often associated with a poor survival prognostic for patients. The main reason seems to be the acquired or inherent resistance to the chemotherapeutic agent used to treat the tumor, temozolomide (TMZ). To this day, the most recognized pathway of resistance is the DNA Direct Repair pathway by the means of the protein O6-methylguanine DNA-methyltransferase (MGMT). Objectives: To design and synthesize a series of MGMT inhibitors that can sensitize GBM cells to TMZ. Methods: Twenty-five O6-alkyl, O6-aryl and O6-substituted-aryl guanine analogs including nine novel compounds were synthesized, characterized, analyzed by molecular docking and tested on the T98G GBM cells viability. Results: Following molecular modeling with MGMT, the newly designed compounds 19, 22, and 24 emerged as the most promising MGMT ligands and displayed modest cytotoxicity. Guanine analog (19), bearing a p-nitrobenzyl moiety, reduced considerably the O6-methylguanine DNA-methyltransferase expression level. When combined with TMZ (1), which is used as first line treatment for brain tumors, compounds 19, 22, and 24 decreased T98G cellsoproliferation by 32%, 68% and 50%, respectively. TMZ (1) displayed negligible effect on the proliferation of these cells further supporting the notion that this cell model is resistant to this alkylating agent. Conclusion: Overall, these results notably highlight a group of MGMT inhibitors that warrants further exploration in the development of therapeutic options to circumvent TMZ resistance in brain tumors.
