S. Chiha, M. Spilles, J. r.-M. Neudörfl, H.-G. n. Schmalz, Synlett 2019, 30, A-D. 10.1055/s-0037-1612306

Abstract

A conceptually novel and stereoselective synthesis of the en- antiopure octahydroindole building block and its conversion into the ACE inhibitor trandolapril was achieved. Key steps include the -allyla- tion of a protected L-pyroglutamic acid derivative, a highly diastereose- lective Hosomi–Sakurai reaction and a Ru-catalyzed ring-closing me- tathesis of a 4,5-diallylated proline. This way, the synthesis of trandolapril was efficiently achieved in 25% overall yield (12 steps).

Abstract

Centrosome amplification is a hallmark of human cancers that can trigger cancer cell invasion. To survive, cancer cells cluster amplified extra centrosomes and achieve pseudobipolar division. Here, we set out to prevent clustering of extra centrosomes. Tubulin, by interacting with the centrosomal protein CPAP, negatively regulates CPAP‐dependent peri‐centriolar material recruitment, and concurrently microtubule nucleation. Screening for compounds that perturb CPAP–tubulin interaction led to the identification of CCB02, which selectively binds at the CPAP binding site of tubulin. Genetic and chemical perturbation of CPAP–tubulin interaction activates extra centrosomes to nucleate enhanced numbers of microtubules prior to mitosis. This causes cells to undergo centrosome de‐clustering, prolonged multipolar mitosis, and cell death. 3D‐organotypic invasion assays reveal that CCB02 has broad anti‐invasive activity in various cancer models, including tyrosine kinase inhibitor (TKI)‐resistant EGFR‐mutant non‐small‐cell lung cancers. Thus, we have identified a vulnerability of cancer cells to activation of extra centrosomes, which may serve as a global approach to target various tumors, including drug‐resistant cancers exhibiting high incidence of centrosome amplification.


An Atom-Economic and Stereospecific Access to Trisubstituted Olefins through Enyne Cross Metathesis Followed by 1,4-Hydrogenation

F. Ratsch, H.-G. Schmalz, Synlett 2018, 29, 785-792. 10.1055/s-0036-1591528

Abstract

The combination of intermolecular enyne cross metathesis and subsequent 1,4-hydrogenation opens a stereocontrolled and atom-economic access to trisubstituted olefins. By investigating different combinations of functionalized alkyne and alkene substrates, we found that the outcome (yield, E/Z ratio) of the Grubbs II-catalyzed enyne cross-metathesis step depends on the substrate’s structure, the amount of the alkene (used in excess), and the (optional) presence of ethylene. In any case, the 1,4-hydrogenation, catalyzed by 1,2-di­methoxybenzene-Cr(CO)3, proceeds stereospecifically to yield exclusively the E-products from both the E- and Z-1,3-diene intermediates obtained by metathesis. A rather broad scope and functional group compatibility of the method is demonstrated by means of 15 examples.


Chiral Phosphine–Phosphite Ligands in Asymmetric Gold Catalysis: Highly Enantioselective Synthesis of Furo[3,4‐d]‐Tetrahydropyridazine Derivatives through [3+3]‐Cycloaddition

Q. Du, J.-M. Neudoerfl, H.-G. Schmalz, Chem. - Eur. J. 2018, 24, 2379-2383. 10.1002/chem.201800042

Abstract

The AuI‐catalyzed reaction of 2‐(1‐alkynyl)‐2‐alken‐1‐ones with azomethine imines regio‐ and diastereoselectively affords furo[3,4‐d]tetrahydropyridazines in a tandem cyclization/intermolecular [3+3]‐cycloaddition process under mild conditions. By employing a chiral gold catalyst (prepared in situ from a Taddol‐derived phosphine‐phosphite ligand, Me2SAuCl, and AgOTf) high yields and enantioselectivities (up to 94 % yield, up to 96 % ee) are obtained. The method provides an efficient modular route to substituted heterotricyclic furan derivatives and can be easily scaled up (using catalyst loads of only 0.15 mol %).


Synthetic Indolactam V Analogues as Inhibitors of PAR2‐Induced Calcium Mobilization in Triple‐Negative Breast Cancer Cells

J. Stein, S. Stahn, J.-M. Neudoerfl, J. Sperlich, H.-G. Schmalz, N. Teusch, ChemMedChem 2018, 13, 147-154. 10.1002/cmdc.201700640

Abstract

Human proteinase‐activated receptor 2 (PAR2), a transmembrane G‐protein‐coupled receptor (GPCR), is an attractive target for a novel anticancer therapy, as it plays a critical role in cell migration and invasion. Selective PAR2 inhibitors therefore have potential as anti‐metastatic drugs. Knowing that the natural product teleocidin A2 is able to inhibit PAR2 in tumor cells, the goal of the present study was to elaborate structure–activity relationships and to identify potent PAR2 inhibitors with lower activity against the adverse target, protein kinase C (PKC). For this purpose, an efficient gram‐scale total synthesis of indolactam V (i.e., the parent structure of all teleocidins) was developed, and a library of derivatives was prepared. Some compounds were indeed found to exhibit high potency as PAR2 inhibitors at low nanomolar concentrations with improved selectivity (relative to teleocidin A2). The pseudopeptidic fragment bridging the C3 and C4 positions of the indole core proved to be essential for target binding, whereas activity and target selectivity depends on the substituents at N1 or C7. This study revealed novel derivatives that show high efficacy in PAR2 antagonism combined with increased selectivity.


Design and Synthesis of Building Blocks for PPII‐Helix Secondary‐Structure Mimetics: A Stereoselective Entry to 4‐Substituted 5‐Vinylprolines

S. Chiha, A. Soicke, M. Barone, M. Mueller, J. Bruns, R. Opitz, J.-M. Neudoerfl, R. Kuehne, H.-G. Schmalz, Eur. J. Org. Chem. 2018, 2018, 455-460. 10.1002/ejoc.201701584

Abstract

In the course of our studies towards the synthesis of proline‐based secondary‐structure mimetics, we developed a straightforward methodology for the diastereoselective preparation of 4‐alkyl‐5‐vinyl‐substituted proline derivatives. Starting from N‐Boc‐protected tert‐butyl pyroglutamate, α‐alkylation, lactam reduction and acid‐catalyzed methanolysis afforded 4‐alkyl‐5‐methoxyproline derivatives. After BF3‐induced formation of an N‐acyl‐iminium intermediate, the introduction of the 5‐vinyl side chain was achieved with high diastereoselectivity by using vinylmagnesium bromide in the presence of AlCl3 or CuBr·SMe2 to afford either the cis‐ or the trans‐product, respectively. The utility of the method was demonstrated in the rapid and efficient construction of new diproline mimetics rigidified in a polyproline‐type II helix (PPII) conformation.


Methyl Fumarate‐Derived Iron Carbonyl Complexes (FumET‐CORMs) as Powerful Anti‐inflammatory Agents

B. Bauer, A.-L. Goederz, H. Braumueller, J. M. Neudoerfl, M. Roecken, T. Wieder, H.-G. Schmalz, ChemMedChem 2017, 12, 1927-1930. 10.1002/cmdc.201700488

Abstract

Autoimmune diseases are characterized by dendritic cell (DC)‐driven activation of pro‐inflammatory T cell responses. Therapeutic options for these severe diseases comprise small molecules such as dimethyl fumarate, or “gasotransmitters” such as CO. Herein we describe the synthesis of bifunctional enzyme‐triggered CO‐releasing molecules (ET‐CORMs) that allow the simultaneous intracellular release of both CO and methyl fumarate. Using bone‐marrow‐derived DCs the impressive therapeutic potential of these methyl fumarate‐derived compounds (FumET‐CORMs) is demonstrated by strong inhibition of lipopolysaccharide‐induced pro‐inflammatory signaling pathways and blockade of downstream interleukin‐12 or ‐23 production. The data also show that FumET‐CORMs are able to transform DCs into an anti‐inflammatory phenotype. Thus, these novel compounds have great clinical potential, for example, for the treatment of psoriasis or other inflammatory conditions of the skin.


Ergothioneine stands out from hercynine in the reaction with singlet oxygen: Resistance to glutathione and TRIS in the generation of specific products indicates high reactivity

C. Stoffels, M. Oumari, A. Perrou, A. Termath, W. Schlundt, H.-G. Schmalz, M. Schaefer, V. Wewer, S. Metzger, E. Schoemig, D. Gruendemann, Free Radical Biol. Med. 2017, 113, 385-394. 10.1016/j.freeradbiomed.2017.10.372

Abstract

The candidate vitamin ergothioneine (ET), an imidazole-2-thione derivative of histidinebetaine, is generally considered an antioxidant. However, the precise physiological role of ET is still unresolved. Here, we investigated in vitro the hypothesis that ET serves specifically to eradicate noxious singlet oxygen (1O2). Pure 1O2 was generated by thermolysis at 37 °C of N,N'-di(2,3-dihydroxypropyl)-1,4-naphthalenedipropanamide 1,4-endoperoxide (DHPNO2). Assays of DHPNO2 with ET or hercynine (= ET minus sulfur) at pH 7.4 were analyzed by LC-MS in full scan mode to detect products. Based on accurate mass and product ion scan data, several products were identified and then quantitated as a function of time by selected reaction monitoring. All products of hercynine contained, after a [4+2] cycloaddition of 1O2, a carbonyl at position 2 of the imidazole ring. By contrast, because of the doubly bonded sulfur, we infer from the products of ET as the initial intermediates a 4,5-dioxetane (after [2+2] cycloaddition) and hydroperoxides at position 4 and 5 (after Schenck ene reactions). The generation of single products from ET, but not from hercynine, was fully resistant to a large excess of tris(hydroxymethyl)aminomethane (TRIS) or glutathione (GSH). This suggests that 1O2 markedly favors ET over GSH (at least 50-fold) and TRIS (at least 250-fold) for the initial reaction. Loss of ET was almost abolished in 5 mM GSH, but not in 25 mM TRIS. Regeneration of ET seems feasible, since some ET products – by contrast to hercynine products - decomposed easily in the MS collision cell to become aromatic again.


New Colchicine-Derived Triazoles and Their Influence on Cytotoxicity and Microtubule Morphology

P. Thomopoulou, J. Sachs, N. Teusch, A. Mariappan, J. Gopalakrishnan, H.-G. Schmalz, ACS Med. Chem. Lett. 2016, 7, 188-191. 10.1021/acsmedchemlett.5b00418

Abstract

A series of new colchicinoids with a variable triazole unit at C-7 was synthesized through Cu(I)-catalyzed 1,3-dipolar cycloaddition (click-chemistry) of a colchicine-derived azide with various alkynes and the cytotoxicity against THP-1 and Jurkat cancer cell lines was used for structural optimization. Three particularly active compounds (IC50 ≤ 5 nM) were additionally investigated with respect to their efficacy against relevant solid tumor cell lines (HeLa, A549, and SK MES 1). Besides distorting the microtubule morphology by tubulin depolymerization, one compound also exhibited a pronounced centrosome declustering effect in triple negative breast cancer cells (MDA-MB-231) and nonsmall cell lung cancer cells (H1975).
