In the present work, the catalytic potential of natural organo-catalyst thiamine hydrochloride is explored for the synthesis of 1,2,4-triazolidine-3-thiones in aqueous medium. The reaction of thiosemicarbazides with various substrates viz aryl/ heteroaryl aldehydes, isatins, cyclic and aromatic ketones to obtain corresponding 1,2,4-triazolidine-3-thiones have been successfully demonstrated for the first time. The method proposed in this work addresses the green chemistry principles such as biodegradable catalyst, ambient reaction condition, shorter reaction time, high yield of the products, recyclability of catalyst and high atom economy.

In the presence of copper sulfate, the three-component reaction of aromatic aldehydes, ethylindole-3-acetate and 4-arylidene-5-methyl-2-phenylpyrazol-3-ones, in refluxing toluene afforded spiro[carbazole-3,4′-pyrazoles] in good yields with high diastereoselectivity. More importantly, the similar CuSO4 promoted the four-component reaction of two molecular aromatic aldehydes with ethylindole-3-acetate and 5-methyl-2-phenyl-pyrazol-3-one resulted in 2,4-diarylspiro[carbazole-3,4′-pyrazoles] in satisfactory yields. Additionally, CuSO4 promoted the four-component reaction of two molecular aromatic aldehydes, ethylindole-3-acetate and 2-phenylthiazol-4-one, in refluxing toluene gave 2,4-diarylspiro[carbazole-3,4′-thiazoles] with diastereomeric ratios in the range of 3:1 to 20:1.

Intermediates in aromatic amino acid biosynthesis can serve as substrates for the synthesis of bioactive compounds. In this study we used two intermediates in the shikimate pathway of Escherichia coli, chorismate and anthranilate, to synthesize three bioactive compounds: 4-hydroxycoumarin (4-HC), 2,4-dihydroxyquinoline (DHQ), and 4-hydroxy-1-methyl-2(1H)-quinolone (NMQ). We introduced genes for the synthesis of salicylic acid from chorismate to supply the substrate for 4-HC and the gene encoding N-methyltransferase for the synthesis of N-methylanthranilate from anthranilate. Polyketide synthases and coenzyme (Co)A ligases were tested to determine the optimal combination of genes for the synthesis of each compound. We also tested several constructs and identified the best one for increasing levels of endogenous substrates for chorismate, anthranilate, and malonyl-CoA. With the use of these strategies, 255.4 mg/L 4-HC, 753.7 mg/L DHQ, and 17.5 mg/L NMQwere synthesized. This work provides a basis for the synthesis of diverse coumarin and quinoline derivatives with potential medical applications.

Alicyclic polymers with in-chain aliphatic rings promote improved thermal and optical performance due to backbone rigidity but remain limited in their functional diversity. In this paper we report the first polyester system with solely alicyclic ring connectivity, afforded through ring-opening of a bicyclic dioxane-4-one ring. Polymerisation of the accessibletransisomer is challenging, but affords a novel family of polymers and copolymers.

Here-in, we present molecular design, chemical synthesis and evaluation of novel chromenyl-based 2-iminothiazolidin-4-one derivatives as tubulin polymerization inhibitors. The newly synthesized compounds were evaluated for their in vitro cytotoxicities against A549 (lung cancer), MDA-MB-231 and BT-471 (breast cancer), HepG2 (liver cancer) and HCT-116 (colon cancer) cell lines by MTT assay. Among the synthesized compounds, compound 12b showed excellent anticancer activity on MDA-MB-231 cell line with IC50 value of 0.95 +/- 1.88 mu M and was verified to be safe in normal human bronchial epithelial cells (Beas-2B). Apoptosis induced by the lead 12b was observed using morphological observations, AO/EB and DAPI staining procedures. Further, dose-dependent increase in the depolarization of mitochondrial membrane was also observed through JC-1 staining. Annexin V-FITC/PI assay confirmed that 12b induced early apoptosis. Additionally, cell cycle analysis indicated that the MDA-MB-231 cells were arrested at sub-G2/M phase and also inhibited tubulin polymerization with IC50 value of 3.54 +/- 0.2 mM. Molecular docking simulations were employed to identify the important binding modes responsible for the tubulin inhibitory activity, thus supporting their effective anticancer potential.

A simple, efficient and economical liquid-liquid extraction method has been developed for quantitative extraction of mercury(II) from aqueous buffer solution using furosemide in benzyl alcohol. The effect of various parameters and of various anions and cations on the extraction of mercury(II) was investigated. The separation factor of mercury was quite high in the presence of a number of transition and rare earth metals at pH 3.5. Among strippants, sodium thiosulphate was found most suitable, and the recovery of mercury was noted to be 98%. The stoichiometric composition of the extracted species was found to be [Hg(FS)(2)].

Approximately 60% of human cancers exhibit enhanced activity of ERK1 and ERK2, reflecting their multiple roles in tumor initiation and progression. Acquired drug resistance, especially mechanisms associated with the reactivation of the MAPK (RAF/MEK/ERK) pathway represent a major challenge to current treatments of melanoma and several other cancers. Recently, targeting ERK has evolved as a potentially attractive strategy to overcome this resistance. Herein, we report the design and synthesis of novel series of fused naphthofuro[3,2-c] quinoline-6,7,12-triones 3a-f and pyrano[3,2-c]quinoline-6,7,8,13-tetraones 5a,b and 6, as potential ERK inhibitors. New inhibitors were synthesized and identified by different spectroscopic techniques and X-ray crystallography. They were evaluated for their ability to inhibit ERK1/2 in an in vitro radioactive kinase assay. 3b and 6 inhibited ERK1 with IC50s of 0.5 and 0.19 mu M, and inhibited ERK2 with IC50s of 0.6 and 0.16 mu M respectively. Kinetic mechanism studies revealed that the inhibitors are ATP-competitive inhibitors where 6 inhibited ERK2 with a K-i of 0.09 mu M. Six of the new inhibitors were tested for their in vitro anticancer activity against the NCI-60 panel of tumor cell lines. Compound 3b and 6 were the most potent against most of the human tumor cell lines tested. Moreover, 3b and 6 inhibited the proliferation of the BRAF mutant A375 melanoma cells with IC50s of 3.7 and 0.13 mu M, respectively. In addition, they suppressed anchorage-dependent colony formation. Treatment of the A375 cell line with 3b and 6 inhibited the phosphorylation of ERK substrates p-90RSK and ELK-1 and induced apoptosis in a dose dependent manner. Finally, a molecular docking study showed the potential binding mode of 3b and 6 within the ATP catalytic binding site of ERK2.

In this work, we report a thorough investigation of the reaction of phenols with aryldiazoacetates. Mechanistic studies using different spectroscopic methods and theoretical calculations suggest a hydrogen bond between phenol and aryldiazoacetates, which can be modulated by the phenol acidity. The pK(A) of phenol and therefore the hydrogen bond plays an important role in a subsequent photoinduced proton transfer reaction to give the formal O-H functionalization product of phenols.
