Iodine-Mediated Sulfenylation of Imidazo[1,2- a ]pyridines with Ethyl Arylsulfinates

A simple iodine-mediated approach is reported for the synthesis of sulfenylated imidazo[1,2- a ]pyridines through the reaction of imidazo[1,2- a ]pyridines with ethyl arylsulfinates under mild conditions. The reaction scope was investigated, and a plausible mechanism is proposed to elucidate the reaction process and activation mode. The results indicate that ethyl sulfinates are efficient sulfur sources for the construction of C-S bonds.

A mild and chemoselective CALB biocatalysed synthesis of sulfoxides exploiting the dual role of AcOEt as solvent and reagent

A mild, chemoselective and sustainable biocatalysed synthesis of sulfoxides has been developed exploiting CALB and using AcOEt with a dual role of more environmentally friendly reaction solvent and enzyme substrate. A series of sulfoxides, including the drug omeprazole, have been synthesised in high yields and with excellent E-factors.

Design, synthesis and anticancer/antiestrogenic activities of novel indole-benzimidazoles

Indole-benzimidazoles have recently gained attention due to their antiproliferative and antiestrogenic effects. However, their structural similarities and molecular mechanisms shared with selective estrogen receptor modulators (SERMs) have not yet been investigated. In this study, we synthesized novel ethylsulfonyl indole-benzimidazole derivatives by substituting the first (R1) and fifth (R2) positions of benzimidazole and indole groups, respectively. Subsequently, we performed 1H NMR, 13C NMR, and Mass spectral and in silico docking analyses, and anticancer activity screening studies of these novel indole-benzimidazoles. The antiproliferative effects of indole-benzimidazoles were found to be more similar between the estrogen (E2) responsive cell lines MCF-7 and HEPG2 in comparison to the Estrogen Receptor negative (ER-) cell line MDA-MB-231. R1:p-fluorobenzyl group members were selected as lead compounds for their potent anticancer effects and moderate structural affinity to ER. Microarray expression profiling and gene enrichment analyses (GSEA) of the selected compounds (R1:p-fluorobenzyl: 48, 49, 50, 51; R1:3,4-difluorobenzyl: 53) helped determine the similarly modulated cellular signaling pathways among derivatives. Moreover, we identified known compounds that have significantly similar gene signatures to that of 51 via queries performed in LINCS database; and further transcriptomics comparisons were made using public GEO datasets (GSE35428, GSE7765, GSE62673). Our results strongly demonstrate that these novel indole-benzimidazoles can modulate ER target gene expression as well as dioxin-mediated aryl hydrocarbon receptor and amino acid deprivation-mediated integrated stress response signaling in a dose-dependent manner.

Synthesis of Aromatic Sulfones from SO2 and Organosilanes Under Metal-free Conditions

The conversion of SO2 into arylsulfones under metal-free conditions was achieved for the first time by reacting SO2 with (hetero)arylsilanes and alkylhalides in the presence of a fluoride source. The mechanism of this transformation was elucidated based on DFT calculations, which highlight the influence of SO2 in promoting C?Si bond cleavage.

Synthetic method of 2-amino-4-(ethylsulfonyl) phenol

The invention provides a synthetic method of 2-amino-4-(ethylsulfonyl) phenol. The method comprises the following steps that firstly, 4-ethylsulfonyl-2-nitro-chlorobenzene and alkali are subjected to a reaction in a solvent to obtain 4-(ethylsulfonyl)-2-nitro-phenol; then, the 4-(ethylsulfonyl)-2-nitro-phenol obtained in the last step is reduced to obtain 2-amino-4-(ethylsulfonyl) phenol. The novel synthesis route is designed, no high temperature or high pressure is needed in the reaction process, reaction conditions are mild, and the reaction yield and product purity are high, so that the production cost of the product is lowered, the product quality is improved, the preparation technology is more reasonable, and large batch industrial production is facilitated.

Kinetic investigation on the highly efficient and selective oxidation of sulfides to sulfoxides and sulfones with t-BuOOH catalyzed by La2O3

The selective oxidation of various sulfides to sulfoxides by a simple, efficient, and environmentally benign method is of prime focus. In this paper, we have explored a highly efficient protocol for the oxidation of alkyl aryl sulfides to sulfoxides with high selectivities catalyzed by La2O3 in the presence of 70% t-BuOOH solution (water). We obtained predominantly the monooxygenated product. The over oxidation of sulfides to sulfones was not observed under these conditions. The resulting products are obtained in good to excellent yields within a reasonable time without the use of ligands and other additives. The epoxidation of the double bond as well as allylic oxidation are not observed with allyl sulfides. Sulfones can be obtained quantitatively by altering the reaction conditions. The surface morphology and the catalyst reusability were verified by XRD, AFM and SEM techniques. The surface area of the La2O3 was measured using BET isotherms.

Syntheses and In Vitro Anticancer Properties of Novel Radiosensitizers

Series of 4-(ethylsulfonyl)-1-halogen-2-nitrobenzene (3a-e) and 1-(4-halogen-3-nitrophenyl) propan-1-one (5a-d) analogs designed as novel radiosensitizers using bromonitropropiophenone and bromonitrobenzonitrile as lead compounds were synthesized. The anticancer activities of the compounds were evaluated in vitro using human prostate cancer (DU-145) and breast cancer (MCF-7) cell lines and the MTT assay. From the series, six compounds (3b-e, 5b-c) exhibited potent growth inhibitory effects against both cell lines. The most active, compound 3d, is an iodosulfone and is significantly more potent than the lead compound 5c at 10μm. Compounds were then compared with doxorubicin, a clinically used anticancer compound for breast and prostate cancers. Our most active compound 3d is more effective than doxorubicin at the dose level of 10μm at 3days after radiation, cell viabilities of 18%, 13% compared to 87%, 94% against MCF-7, and 15%, 20% compared to 60%, 75% against DU-145 without and with radiation, respectively. At 10μm, compound 5c had no effects as compared to control, whereas compound 3d reduced DU-145 cell viability to 16% and that of MCF-7 cells to 9% even at 5days after radiation. These results are very encouraging. Future studies include testing the compounds in vivo with and without radiation. Our most active compound 3d is significantly more effective than doxorubicin or lead compound 5c at the dose level of 10μm, without and with radiation; and in MCF-7 and DU-145 cell lines. These results are very encouraging. Future studies include testing the compounds in vivo without and with radiation.

5-Sulfonyl-benzimidazoles as selective CB2 agonists

A novel series of benzimidazole CB2-receptor agonists was synthesized and the structure-activity relationship explored. The results showed agonistic activities with an EC50 up to 0.5 nM and excellent selectivity (>4000-fold) over the CB1 receptor. The size of the substituent on the 2-position determined the level of agonism, ranging from inverse agonism to partial agonism to full agonism, which was more pronounced for the rat CB2 receptor. A wide variation of sulfonyl substituents at the benzimidazole 5-position was tolerated, which was used to optimize the drug-like properties. This resulted into lead compound 14j that can be used to investigate the potential of a selective, peripherically acting CB2 agonist. The in vitro profile of key compounds is displayed using pie bar charts (VlaaiVis).
