In this Paper the Two-Stage Method of Enzyme-Mild Acidic Hydrolysis was Adopted to Separate Lignin from the APMP and the Modified Pulp Samples.And then Analyze the Lignin Structure Changes of the Modified APMP Lignin by Laccase and LMS(laccase/mediator System). it was Found that no Oxidation Took Place on Carbohydrates in the LMS, and Lignin Cα Hydroxyl Oxidization Produce α Carbonyl and H2O2 Bleaching can also Oxidation of Lignin, make the Conjugate C = α Increase;the Syringyl Structure Hydroxyl Content Increase, the Lignin Structure Macromolecular Side Chain Fracturing; Laccase and LMS Oxidative Degradation Chromophoric Group Unsaturated C = O, which can Improve the Brightness of Pulp and Create Better Conditions for Unbleached Pulp.

A novel one-pot catalytic synthesis of 1-benzoylpyrene through acylation of pyrene with benzoyl chloride catalyzed by various Keggin type heteropoly acids (salts) was investigated. Pure 1-benzoylpyrene was obtained and the structure of 1-benzoylpyrene was identified by GC/MS, FT-IR and 1H NMR spectra. H3PW12O40 (PW) was found to be the most active catalyst in the acylation. The yield and the selectivity of 1-benzoylpyrene were up to 97.6 % and 100 %, respectively. The effects of experimental parameters on the catalytic acylation reaction and the recycling performance of PW catalyst were studied. PW catalyst shows well catalytic activity after running for 5 times. The facile product separation and the recycling performance of PW catalyst is expected to contribute to the development of clean and environmentally friendly strategy for the synthesis of 1-benzoylpyrene.

Cox 2 Inhibitors

A simple and efficient catalytic synthesis of new 1H-pyrazole-1-carbothioamide derivatives through a one-pot reaction of hydrazine hydrate, arylidene malononitrile and isothiocyanates in the presence of HAp/ZnCl2 nano-flakes at 60-70°C has been described. The protocol's main advantages include high yields of products, a wide range of substrates, simple procedure, and short reaction time. Molecular docking studies of the designed compounds were accomplished as COX-2 inhibitors and showed that compounds 3d, 3e, 3h, and 3n give promising results compared with celecoxib as a reference drug.
