Arylnitration of alkenes by nitration/C-H functionalization cascade using AgNO3 and HOAc

A novel arylnitration of alkenes by nitration and C-H functionalization cascade process has been developed. This methodology provides an efficient way to construct a variety of nitro-containing oxindoles and dihydroquinolin-2(1H)- ones. In addition, the process exhibits significant functional group tolerance. Moreover, the use of inexpensive and readily available starting materials makes this practical and atom-economical approach particularly attractive.

Design, synthesis and evaluation of novel polypharmacological antichlamydial agents

Abstract Discovery of new polypharmacological antibacterial agents with multiple modes of actions can be an alternative to combination therapy and also a possibility to slow development of antibiotic resistance. In support to this hypothesis, we synthesized 16 compounds by combining the pharmacophores of Chlamydia trachomatis inhibitors and inhibitors of type III secretion (T3S) in gram-negative bacteria. In this study we have developed salicylidene acylhydrazide sulfonamides (11c & 11d) as new antichlamydial agents that also inhibit T3S in Yersinia pseudotuberculosis.

Evolution of PIKK family kinase inhibitors: A new age cancer therapeutics

Phosphatidylinositol-3 kinase-related kinases (PIKKs) belong to a family of atypical serine/threonine kinases in humans. They actively participate in a diverse set of cellular functions such as meiotic, V(D)J recombination, chromosome maintenance, DNA damage sensing and repair, cell cycle progression and arrest. ATR, ATM, DNA-PKcs, mTOR and hSMG are the members of the PIKK family that play an important role in in cancer cell proliferation, autophagy, and cell survival to radio and chemotherapy. Thereby targeting these PIKK kinases in cancer along with chemo/radiotherapy agents, can help in differential cytotoxicity towards cancer cell over the normal cell. In this review, we compile the various small molecule kinase inhibitors with respect to structural and strategic targeting of PIKK family members. Rapalogs, AZD8055, AZD2014, OSI-027, INK-128, MLN0128, VX970, NVP-BEZ235, Torin2, AZ20, and AZ31 are the diverse scaffolds which have successfully made into the pre-clinical trials either as mono or combinatorial therapy for the treatment of various human cancers. Their synthesis and pre-clinical trial highlight the challenges associated in the development process.

Synthesis and evaluation of anticonvulsant activities of 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives

Fifteen new 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives (4-18) were synthesized and evaluated for their preliminary anticonvulsant activity and neurotoxicity by using the maximal electroshock (MES) and rotarod tests. The structures of synthesized compounds were established by IR,1H NMR,13C NMR and mass spectral data. Among the compounds studied, 5-(3-fluorobenzylidene)-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one (8) was the most potent compound, with a median effective dose of 43.9 mg/kg and a high protective index (PI) of more than 11.1 after intraperitoneal administration in mice. Compound 8 showed significant oral activity against MES-induced seizures in mice, with an ED50 of 84.2 mg/kg and a PI above 11.8. These results demonstrate that compound 8 is safer than the commercially drugs.

Decisive properties of solvent able to form gels with syndiotactic polystyrene

The thermoreversible gel formation of syndiotactic polystyrene (SPS) was studied in detail. Even if SPS solutions with high concentrations did not form gels, there were the cases where SPS formed gels at lower concentrations of SPS, which favor the formation of a polymer-solvent molecular compound. Sixty-two solvent compounds were examined in regard to whether they could form SPS gels. All the compounds whose molecular volume is between 69 and 153 A3 and whose Fedors’ solubility parameter value is between 8.8 and 12.3 (cal/cm3)1/2 were found to produce SPS gels as solvent. Since a solvent molecule that can form SPS gel can be a guest of SPS delta co-crystalline phase, it has become convenient to find functional molecules able to co-crystallize with SPS by taking into account these conditions of gelation solvent molecules.

SiO2 was found to possess favorable catalytic activity and dispersancy for the condensation reaction. The merits of this method include the environmentally friendly reaction conditions, simple operation, broad substrate, satisfied yields and the reuse of the silica. Moreover, the crystal structure of the compound 2-(4-chlorophenyl)-4-((1-(4-chlorophenyl)-5-hydroxy-3-methyl-1H-pyrazol-4-yl)(3-phenylisoxazol-5-yl)methyl)-5-methyl-1H-pyrazol-3(2H)-one (5a) in the monoclinic space group C2/c was presented.

A novel strategy of successive non-radical and radical process for enhancing the utilization efficiency of persulfate

During the process of persulfate oxidation, side reactions such as the recombination of radicals can usually result in the low utilization efficiency of persulfate, which decreases the mineralization of target pollutants. In this study, the successive oxidation strategy was proposed based on successive non-radical and radical process (SNRP), to enhance the utilization efficiency of peroxymonosulfate (PMS), and further enhance the mineralization of sulfonamides. The results indicated that 0.04 mM of sulfonamide could be completely removed within 240 min at 1.2 mM PMS and initial pH 6.8 in the non-radical process, but the mineralization was very low (<2%). Moreover, the decomposition efficiency of PMS was less than 10% within 480 min. Fe(II) was added into the solution in which non-radicals process was performed, to initiate radical process by activating residual PMS. Compared to Fe(II)/PMS process, the SNRP process significantly increased the mineralization of sulfonamides, reaching 27.0%, 19.0%, 16.7% and 17.2%, respectively for sulfamethoxazole, sulfanilamide, sulfadiazine and sulfamerazine. The increased mineralization was due to the enhanced PMS utilization. Seven degradation products were identified in the SNRP process. Among them, hydrolyzed 3-amino-5-methyl isoxazole, (3-amino-5-methylisoxazole) sulfonic acid and 4-aminobenzenesulfinic acid produced in the non-radical oxidation process showed resistance to the subsequent radical oxidation. This study can provide a possible way to enhance the utilization efficiency of PMS as well as the mineralization of organic pollutants. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1072-67-9, help many people in the next few years.Safety of 5-Methylisoxazol-3-amine
