Regio- and stereoselective Pd-catalyzed direct arylation of unactivated sp3 C(3)-H bonds of tetrahydrofuran and 1,4-benzodioxane systems

An auxiliary-enabled Pd-catalyzed highly regio- and stereoselective sp3 C-H activation and the direct arylation of the C3-position of oxygen heterocycles, such as tetrahydrofuran and 1,4-benzodioxane systems, are reported. An efficient stereoselective construction of cis 2,3-disubstituted tetrahydrofuran derivatives (analogues of norlignans) and cis 2,3-disubstituted 1,4-benzodioxane derivatives (analogues of neolignans) is described. The direct C(sp3)-H arylation of the C3-position of (R)- or (S)- tetrahydrofuran-2-carboxamides furnished the corresponding (2R,3R) and (2S,3S) C3-arylated THF scaffolds as major compounds with very high regio- and diastereoselectivities. The stereochemistry of the products obtained in this work were unambiguously assigned on the basis of the X-ray structure analyses of representative compounds 3b, 3e, 4p, and 7.

Synthesis and biological evaluation of chromone carboxamides as calpain inhibitors

Excessive calpain activations contribute to serious cellular damage and have been found in many pathological conditions. Novel chromone carboxamides derived from ketoamides were prepared and evaluated for mu-calpain inhibition. Among synthesized, compound 2i was the most potent calpain inhibitor with an IC50 value of 0.24 ¡À 0.11 muM comparable to the activity of peptide aldehyde calpain inhibitor MDL 28,170. Furthermore, compound 2i showed higher selectivity for mu-calpain over two related cysteine proteases cathepsin B and cathepsin L, suggesting the chromone ring as a good scaffold for selective mu-calpain inhibitors.

Antiproliferative activity and SARs of caffeic acid esters with mono-substituted phenylethanols moiety

A series of CAPE derivatives with mono-substituted phenylethanols moiety were synthesized and evaluated by MTT assay on growth of 4 human cancer cell lines (Hela, DU-145, MCF-7 and ECA-109). The substituent effects on the antiproliferative activity were systematically investigated for the first time. It was found that electron-donating and hydrophobic substituents at 2?-position of phenylethanol moiety could significantly enhance CAPE’s antiproliferative activity. 2?-Propoxyl derivative, as a novel caffeic acid ester, exhibited exquisite potency (IC50?=?0.4?¡À?0.02 & 0.6?¡À?0.03?muM against Hela and DU-145 respectively).

Column chromatography-free solution-phase synthesis of a natural piper-amide-like compound library

We have achieved an efficient solution-phase parallel synthesis of a library of natural piper-amide-like compounds from the bifunctional beta-phosphono-N-hydroxy-succinimidyl ester intermediate. The primary important feature in our study is the construction of natural-product-like molecules through the adaptation of sophisticated organic reactions that create water-soluble byproducts for a chromatography-free purification. This simple and efficient method rapidly provides a combinatorial library of high yield and purity. The library was evaluated against GPCR targets to demonstrate its potential use as a tool for drug discovery and in chemical biology.

Solution-phase parallel synthesis and SAR of homopiperazinyl analogs as positive allosteric modulators of mGlu4

Using a functional high-throughput screening (HTS) and subsequent solution-phase parallel synthesis approach, we have discovered a novel series of positive allosteric modulators formGlu4, a G-protein coupled receptor. This series is comprised of a homopiperazine central core. The solution-phase parallel synthesis and SAR of analogs derived from this series will be presented. This series of positive allosteric modulators of mGlu4 provide critical research tools to further probe the mGlu4-mediated effects in Parkinson’s disease.

Insecticidal heterolignans-Tubuline polymerization inhibitors with activity against chewing pests

Starting from natural product podophyllotoxin 1 substituted heterolignans were identified with promising insecticidal in vivo activity. The impact of substitution in each segment of the core structure was investigated in a detailed SAR study, and variation of substituents in both aromatic moieties afforded derivatives 5 and 43 with broad insecticidal activity against lepidopteran and coleopteran species. In vitro measurements supported by modeling studies indicate that heterolignans 3-134 act as tubuline polymerization inhibitors interacting with the colchicine-binding site. Insect specific structure-activity effects were observed showing that the insecticidal SAR described herein differs from reported cytotoxicity studies.

Phenylcinnamides as novel antimitotic agents

Compound 8H is a phenylcinnamide that induces G2/M-phase cell cycle arrest and cell death in cancer cell lines. Here we show that 8H exerts its cytotoxic activity through disruption of microtubule dynamics in vitro and in cell culture. A series of cinnamide derivatives were synthesized and evaluated, and several new compounds were identified that improve on the activity of the parent compound, with IC50 values for induction of cell death ranging from 1 to 10 muM. Notably, these compounds retain potency in the HL-60/VCR leukemia cell line, which is resistant to antimitotic cancer drugs vincrisitine and paclitaxel through up-regulation of P-glycoprotein drug efflux pumps. As P-glycoprotein expression is often responsible for drug resistance in cancer and the exclusion of compounds from the central nervous system, 8H and its derivatives merit further examination as potential antimitotic therapeutics, specifically for brain cancers and cancers that are resistant to standard antimitotic agents.

Synthesis and alpha-blocking activity of some cyclic and opened analogues of WB 4101

The synthesis of some cyclic and open analogues of 2-(2,6-dimethoxyphenoxyethylaminomethyl)-1,4-benzodioxane (1, WB 4101) is described. The blocking activity of this compound and its analogues (1-5) was determined on the pre- and postsynaptic alpha-adrenoceptors of isolated rat vas deferens to investigate the structural requirements for conpetitive alpha-adrenoceptor occupancy by antagonists of the benzodioxane class. The activities of 1-5 at the presynaptic alpha-adrenoceptor were not significantly different whereas there were differences among the compounds of at least two orders of magnitude at the postsynaptic alpha-adrenoceptor. This clearly indicates that the structural requirements at the presynaptic receptor level are less restrictive than those required by the postsynaptic alpha-adrenoceptor. The symmetric analogues 3 and 4 were significantly weaker postsynaptic alpha-antagonists compared to 1. On the other hand, 2 and 5 displayed a very high postsynaptic activity, almost comparable to that of 1. These findings might suggest that the antagonists of the benzodioxane class do not bind at two identical aromatic sites symmetrically arranged around the anionic site of the alpha-adrenoceptor. Indeed, they might indicate that the benzodioxane binding site(s) incorporates two areas with very similar but not identical structural requirements. Furthermore, the very high activity of 5 may suggest that the benzodioxane nucleus is not essential to activity.
