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.

Synthesis and biological evaluation of dihydroquinoline carboxamide derivatives as anti-tubercular agents

Sodium trifluoromethanesulfonate, and glacial acetic acid selectively catalyzed the synthesis of dihydroquinoline via Friedlaender annulation. The synthesized dihydroquinoline analogues coupled with different amines by the use of coupling reagent gave dihydroquinoline carboxamide derivatives in moderate to good yields. All the synthesized novel compounds were evaluated for the anti-tubercular activity and cytotoxic activities in vitro. Among tested 30 compounds, two compounds, 8g and 8h showed MIC value of 0.39 and 0.78 mug/mL, respectively against Mycobacterium tuberculosis H37Rv and they were found to be non-toxic. Also these two compounds exhibited good pharmacological properties and oral absorption when studied using in-silico models.

Effect of a-ring modifications on the DNA-binding behavior and cytotoxicity of pyrrolo[2,1-c][1,4]benzodiazepines

Several A-ring-modified analogues of the DNA-binding antitumor agent DC- 81 (5) have been synthesized in order to study structure- reactivity/cytotoxicity relationships. For two molecules (23 and 30) the modifications required the addition of a fourth ring to give the novel dioxolo[4,5-h]- and dioxano[5,6-h]pyrrolo[2,1-c][1,4]benzodiazepin-11-one (PBD) ring systems, respectively. Another three analogues (34, 38, and 48) have the native benzenoid A-ring replaced with pyridine, diazine, or pyrimidine rings to give the novel pyrrolo[2,1-c][1,4]pyridodiazepine, pyrrolo[2,1-c][1,4]diazinodiazepine, and pyrrolo[2,1- c][1,4]pyrimidinodiazepine systems, respectively. The other new analogues (16a,b) have extended chains at the C8-position of the DC-81 structure. During the synthesis of these compounds, a novel tin-mediated regiospecific cleavage reaction of the dioxole intermediate 18 was discovered, leading to the previously unknown iso-DC-81 (20). In addition, an unusual simultaneous nitration-oxidation reaction of 4-(3-hydroxypropoxy)-3-methoxybenzoic acid (8) was found to produce 3-(4-carboxy-2-methoxy-5-nitrophenoxy)propanoic acid (9), a key intermediate, in high yield. In general, the results of cytotoxicity and DNA-binding studies indicated that none of the changes made to the A-ring of the PBD system significantly improved either binding affinity or cytotoxicity in comparison to DC-81. This result suggests that the superior potency of natural products such as anthramycin (1), tomaymycin (2), and sibiromycin (3) is due entirely to differences in C-ring structure, and in particular exo or endo unsaturation at the C2-position and C2- substituents containing unsaturation. This study also provided information regarding the influence of A-ring substitution pattern on the relative stability of the interconvertible N10-C11 carbinolamine, carbinolamine methyl ether, and imine forms of PBDs.

Iron(III)-Catalyzed Arylation of Spiro-Epoxyoxindoles with Phenols/Naphthols towards the Synthesis of Spirocyclic Oxindoles

An efficient and highly regioselective iron(III)-catalyzed Friedel?Crafts-type arylation of spiro-epoxyoxindoles with phenols was developed for rapid access to 3-(3-indolyl)-oxindole-3-methanols, which could be further elaborated into benzofuranyl-spirooxindoles under Mitsunobu conditions. When spiro-epoxyoxindoles were reacted with naphthols in the presence of a catalytic amount of FeCl3?6 H2O in dichloromethane, they underwent a tandem Friedel?Crafts-type arylation and O-cyclization to yield novel naphthofuranyl-spirooxindoles in excellent yields. This method is applied to enable the efficient and highly regioselective synthesis of a small-molecule inhibitor of the sodium channel Nav1.7 (¡À)-XEN402, which is currently in a phase IIb clinical trial for the treatment of pain.
