Synthesis of novel 3-(aryl)benzothieno[2,3-c]pyran-1-ones from Sonogashira products and intramolecular cyclization: Antitumoral activity evaluation

Several novel 3-(aryl)benzothieno[2,3-c]pyran-1-ones (tricyclic lactones) were prepared either by a tandem one-pot Sonogashira coupling and intramolecular cyclization, reacting the 3-bromobenzo[b]thiophene-2-carboxylic acid with arylacetylenes, or by Sonogashira coupling of the methyl 3-bromobenzo[b]thiophene-2-carboxylate or the methyl 3-bromo-6-methoxybenzo[b]thiophene-2-carboxylate with arylacetylenes followed by an electrophilic intramolecular cyclization using iodine or TFA in two separate steps. The Sonogashira products and the tricyclic lactones obtained were evaluated for their capacity to inhibit the in vitro growth of three human tumor cell lines, MCF-7 (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer) and SF-268 (CNS cancer). Most of the compounds showed a high growth inhibitory effect on all the tested cell lines, with GI50 values in the muM range. A structure-activity relationship was established for the Sonogashira products and for the tricyclic lactones, namely related to the presence and position of substituents (OMe and/or F) in the benzothiophene moiety or in the phenyl ring.

An Aryne-Based Route to Substituted Benzoisothiazoles

The combination of arynes, generated using fluoride from the corresponding 2-(trimethylsilyl)aryl triflates, and 3-hydroxy-4-aminothiadiazoles leads to the selective formation of 3-amino-substituted benzo[d]isothiazoles. Variation of the substitution pattern of the aryne precursor, and of the thiadiazole, is possible, with the target heterocycles being obtained in good to excellent yields. In all cases, use of 3-hydroxy-4-aminothiadiazoles leads to incorporation of the amino-substituent in the product heterocycle.

Reactivity of several deactivated 3-aminobenzo[b]thiophenes in the Buchwald-Hartwig C-N coupling. Scope and limitations

Di(hetero)arylamines were prepared in moderate to high yields by Buchwald-Hartwig C-N coupling of bromobenzenes bearing electron-withdrawing groups and of a bromobiphenyl with several methyl 3-aminobenzo[b]thiophene-2-carboxylates, using the coupling conditions for heteroaromatic amines [Pd(OAc)2, Xantphos, Cs2CO3 in dioxane, 120 C]. The use of these aminobenzo[b]thiophenes as coupling components avoids the step of changing the amino group into a bromine atom, like we have done before to perform C-N couplings using the corresponding 3-bromobenzo[b]thiophenes. Nevertheless, the couplings using the methyl 3-aminobenzo[b]thiophene-2-carboxylates were only successful with bromobenzenes bearing electron-withdrawing groups and a bromobiphenyl or with electron deficient rings such us as bromopyridines. Using the latter compounds, different substituted 6H-benzothieno[3,2-d]pyrido[1,2-a]pyrimid-6-ones were obtained by C-N coupling followed by an intramolecular cyclization. These tetracyclic compounds may have interesting biological activity like it was already demonstrated by us for the non substituted derivative.

CODES, a novel procedure for ligand-based virtual screening: PDE7 inhibitors as an application example

Phosphodiesterase (PDE) 7 is a high affinity cAMP-specific PDE whose functional role in T-cells has been the subject of some controversy. Recent findings on tissue distribution, however, support the hypothesis that PDE7 could be a good target for the treatment of airway diseases, T-cell related diseases or central nervous system (CNS) disorders. Therefore, the identification of selective inhibitors targeted against PDE7 enzyme has become an attractive area of research. We report here the first use of the descriptors generated by the CODES program for ligand-based virtual screening. This program codifies molecules from a topological point of view and the generated descriptors are related to the chemical nature of the atoms, the atomic bonds and the connectivity with the rest of the molecule. They are also able to distinguish among stereoisomers. By using this approach, 173 compounds were codified, and their similarity with the reference compound was analysed. Based on the analysis, new potential PDE7 inhibitors have been identified, synthesized and biologically evaluated confirming that CODES descriptors are valid for ligand-based virtual screening and provided new lead compounds for further optimization as potent and selective PDE7 inhibitors.

Syntheses of substituted 2,4-dioxo-thienopyrimidin-1-acetic acids and their evaluation as aldose reductase inhibitors

A series of 2,4-dioxo-thieno[2,3-d], [3,2-d] and [3,4-d]pyrimidin-1-acetic acids (2) with a benzyl moiety at the N-3 position were prepared and tested in vitro for aldose reductase inhibitory activity against partially purified enzyme from rat lens. Some of these compounds were also evaluated for inhibition of sorbitol accumulation in the sciatic nerve or lens of streptozotocin-induced diabetic rats in vivo. Among the synthesized compounds, several showed potent aldose reductase inhibitory activity with IC50s in the 10-8 M range. Particularly, the potencies of non-substituted thieno- (2a and 2aa), 5-methylthieno- (2c), 5,6-dimethylthieno- (2g), 6-isopropylthieno- (2j and 2k), 6-chlorothienopyrimidine (2q) and benzothienopyrimidine (2ac) analogs were approximately equipotent ot FK-366 (1A) and Ponalrestat (1B) as references. Although most compounds were inactive in vivo, 2 compounds, 2k and 2q, possessed moderate in vivo activity.

Structure-activity relationships in the binding of chemically derivatized CD4 to gp120 from human immunodeficiency virus

The first step in HIV infection is the binding of the envelope glycoprotein gp120 to the host cell receptor CD4. An interfacial “Phe43 cavity” in gp120, adjacent to residue Phe43 of gp120-bound CD4, has been suggested as a potential target for therapeutic intervention. We designed a CD4 mutant (D1D2F43C) for site-specific coupling of compounds for screening against the cavity. Altogether, 81 cysteine-reactive compounds were designed, synthesized, and tested. Eight derivatives exceeded the affinity of native D1D2 for gp120. Structure-activity relationships (SAR) for derivatized CD4 binding to gp120 revealed significant plasticity of the Phe43 cavity and a narrow entrance. The primary contacts for compound recognition inside the cavity were found to be van der Waals interactions, whereas hydrophilic interactions were detected in the entrance. This first SAR on ligand binding to an interior cavity of gp120 may provide a starting point for structure-based assembly of small molecules targeting gp120-CD4 interaction.

Synthesis and evaluation of apoptosis induction of thienopyrimidine compounds on KRAS and BRAF mutated colorectal cancer cell lines

Monoclonal antibodies (MoAb) and tyrosine kinase inhibitors (TKI) targeting the EGFR (Epidermal Growth Factor Receptor) pathways are currently used in colorectal cancer treatment. Despite the improvement of median overall survival, resistance is observed notably due to KRAS and BRAF gene mutations. We synthesized four series of thienopyrimidines whose scaffold is structurally close to TKI used in clinical practice. We evaluated apoptosis induced by these compounds using flow cytometry on KRAS and BRAF mutated cell lines. Our results confirm that the mutated cell lines (HCT116 and HT29) are more resistant to apoptosis than the non-mutated cell line (Hela). Interestingly, among the 13 compounds tested, three of them (5b, 6b and 6d) and gefitinib exhibited a noteworthy pro-apoptotic effect, especially on mutated cell lines with an IC50 value between 70 and 110 muM. These three compounds seem particularly attractive for the development of novel treatments for colorectal cancer patients harboring EGFR pathway mutations.

Conversion of 2-thioxo-2,3-dihydroquinazolin-4(1H)-ones to N(3)-unsubstituted 2-(het)arylquinazolin-4(3H)-ones by copper-mediated Pd-catalysed cross-coupling reactions

With the purpose of searching for new heterocyclic building blocks, a new method to access N(3)-unsubstituted 2-(het)arylquinazolin-4(3H)-ones from 2-thioxo-2,3-dihydroquinazolin-4(1H)-one derivatives was developed. The synthetic protocol was based on the copper-mediated palladium-catalysed cross-coupling reactions of 2-thioxo-2,3-dihydroquinazolin-4(1H)-ones with (het)arylstannanes or their S-benzylated derivatives with (het)arylboronic acids, using CuBr¡¤Me2S and CuMeSal as promoters, respectively. A similar transformation was applied for the preparation of 2-aryl[1]benzothieno[3,2-d]pyrimidin-4(3H)-ones.
