Twenty derivatives of chalcones were synthesized and their anticancer activities were estimated against both breast and liver cancer besides two human normal cell lines. Out of our candidates, there were five compounds 3 b, 3 d, 3 h, 7 and 10 b that revealed a broad superlative antitumor activity against both HepG2 and MCF7 cell lines. Surprisingly, 3 h showed the most powerful anticancer activity (GI(50)=5.43 +/- 0.170 mu M for MCF7 and GI(50)=1.80 +/- 0.50 mu M for HepG2) and displayed the most effective inhibition activity on tubulin with IC50=4.51 +/- 0.13 mu M. 3 h exerted low toxicity toward both normal human, Hs371.T and AML12, cell lines. 3 h revealed arrest of cell cycle at G2/M and induced apoptosis compared to control cells. Docking study of all newly derivatives was achieved to decide the preeminent binding mode. Generally, the outcome of the docking study showed that 3 h had better binding mode.

4-Hydroxy-3-methyl-2(1H)-quinolone (1), a molecule known for a long time and recently discovered from a Brassicaceae plant Isatis tinctoria without providing sufficient evidence to support the structure, was isolated from a fermentation extract of Burkholderia sp. 3Y-MMP isolated from a soil by a Zn2+ enrichment culture. Detailed spectroscopic analyses by MS and NMR, combined with C-13 chemical shift comparison with literature values of the related compounds and a synthetic preparation of 1, allowed its first full NMR characterization and identification of 2-quinolone but not 2-quinolinol (2) as the preferred tautomer for this heterocyclic system. While the metal-chelating activity was negligible, compound 1 at 10 mu M, a concentration lower than that in liquid production cultures, quenched hydroxy radical-induced chemiluminescence emitted by luminol by 86%. Because some Burkholderia species are pathogenic to plants and animals, the above result suggests that 1 is a potential antioxidant to counteract reactive oxygen species-based immune response in the host organisms.

Name: 4′-Hydroxyacetophenone. The Name is 4′-Hydroxyacetophenone. Through research, I have a further understanding and discovery of 99-93-4.

A series of triphenyl substituted pyrimidines as analogous of colchicine and combretastatin A-4 was synthesized and evaluated for the antiproliferative potential. The compounds were screened against MDA-MB-231, HCT-116 and HT-29 cell lines using MTT assay. Most of the compounds displayed antiproliferative activity in low to sub micro molar concentration. Amongst the synthesized derivatives, compounds HK-2, HK-10 and HK-13 were found to be effective against all the three cancer cell lines. HK-2 exhibited IC50 values of 3.39 mu M, 4.78 mu M and 4.23 mu M, HK-10 showed IC50 values of 0.81 mu M, 5.89 mu M, 4.96 mu M and HK-13 showed IC50 values 3.24 mu M, 4.93 mu M and 4.73 mu M against MDA-MB-231, HCT-116 and HT-29 cancer cell lines, respectively. HK-10 was found to be the most potent compound in the series with IC50 values of 0.81 mu M against MDA-MB-231. In the cell cycle analysis, HK-2 and HK-10 showed cell arrest at G2/M phase of the cell cycle while HK-13 inhibited cell growth at the G1/G0 phase. All the three compounds showed cell death induced through apoptosis. In the docking studies, HK-2, HK-10 and HK-13 were found to fit well in the colchicine binding site of the tubulin. Some of the compounds in the current series were found to be promising against all the three cancer cell lines and may act as potent leads for further development.

In search of potent anti-inflammatory agents, twenty-four chalcone derivatives including seven new compounds (13 – 17, 21 and 23) containing pyrrole moiety were designed, synthesized, and assessed for their nitric oxide (NO) and prostaglandin E-2 (PGE(2)) suppression ability on IFN-gamma/LPS-induced RAW 264.7 macrophage cells. Results showed that none of the synthesized compounds were PAINS-associated molecules, with 3-(2,5-dimethoxyphenyl)-1-(1H-pyrrol-2-yl) prop-2-en-1-one (compound 16) exhibiting remarkable inhibition activity towards PGE(2) and NO production with IC50 values of 0.5 +/- 1.5 mu M and 12.1 +/- 1.5 mu M, respectively. Physicochemical and ADMET studies showed that majority of the compounds obey to Lipinski’s rule of five (RO5) having high blood brain barrier (BBB) penetration, human intestinal absorption (HIA), P- glycoprotein (PgP) inhibition and plasma binding protein (PPB) inhibition. The obtained atomic coordinates for the single-crystal XRD of 16 were then applied in a molecular docking simulation, and compound 16 was found to participate in a number of important binding interactions in the binding sites of ERK and mPGES-1. Based on these results, we have observed the potential of compound 16 as a new hit anti-inflammatory agent, and these findings could serve as a basis for further studies on its mechanism of action.

Multidrug resistance (MDR) is a major obstacle for effective chemotherapeutic treatment of cancer frequently leading to failure of the therapy. MDR is often associated with the overexpression of ABC transport proteins like ABCB1 or ABCG2 which efflux harmful substances out of cells at the cost of ATP hydrolysis. One way to overcome MDR is to apply potent inhibitors of ABC transporters to restore the sensitivity of the cells toward cytostatic agents. This study focusses on the synthesis and evaluation of novel 2,4-disubstituted quinazoline derivatives regarding the structure-activity-relationship (SAR), their ability to reverse MDR and their mode of interaction with ABCG2. Hence, the inhibitory potency and selectivity toward ABCG2 was determined. Moreover, the intrinsic cytotoxicity and the reversal of MDR were investigated. Interaction type studies with the substrate Hoechst 33342 and conformational analyses of ABCG2 with 5D3 monoclonal antibody were performed for a better understanding of the underlying mechanisms. In our study we could further enhance the inhibitory effect against ABCG2 (compound 31, IC50: 55 nM) and identify the structural features that are crucial for inhibitory potency, the impact on transport activity and binding to the protein.

Oxidative esterification of biomass-derived 5-(hydroxymethyl) furfural (HMF) and furfural and their derivatives has been performed using a simple MnO2/NaCN system. The developed method allows the selective one-pot transformation of HMF to dimethyl furan-2,5-dicarboxylate (FDME) in 83% isolated yield without the formation of a free acid. Simplification of FDME production provides the missing link for manufacturing sustainable value-added materials from biomass. Addition of water to the oxidative system allows fine-tuning of reaction selectivity to obtain the previously difficult-to-access pure methyl 5-(hydroxylmethyl)furan-2-carboxylate in one step directly from the unprotected HMF without chromatographic separation.

One-pot synthesis of hydrazinyl-4-phenyl-1,3-thiazole derivatives was developed by three-component reaction of various ketones or aldehydes, phenacyl chloride, and thiosemicarbazid in the presence of choline chloride/urea as a deep eutectic solvent (DES) at 70 degrees C. The products formed in excellent yields over short reaction times under an environmentally friendly condition. This method develops by using an environmentally benign synthetic method along with the use of a cost-effective catalyst. The study of antibacterial activity revealed that the compounds (4j, 4k, 4l, 4m, 4s, and 4t) showed good inhibition toward Escherichia coli.

A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

Herein we report a novel and straightforward protocol for the construction of valuable gem-BPs by means of proton-coupled electron-transfer (PCET)-triggered enamido C(sp(2))-H diphosphorylation. This reaction represents a rare example of realizing the challenging double C-P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves two rounds of PCET-initiated radical relay process.
