Transfer of nitroso groups, so-called transnitrosation, from aromatic N-nitroso compounds such as N-nitrosoureas, N-nitrosamides and N-nitrosamines, to aromatic amines or ureas was observed under non-acidic conditions at room temperature. Sterically hindered 3,3-dibenzyl-1-(4-tolyl)-1-nitrosourea (1a) rapidly nitrosates indoline, N-alkylanilines or 3-methyl-1-(4-tolyl)urea to give their N-nitroso derivatives. In the case of N,N-dimethylanilines, nitrosative demethylation occurs to give N-methyl-N-nitrosanilines. The transnitrosation is accelerated by electron-releasing groups on the nitroso acceptors, N-alkylanilines. The transnitrosation mechanism is considered to be as follows: N-nitrosourea (1) thermally decomposes to nitric oxide and ureidyl radical followed by formation of an O-nitrosoisourea intermediate (10), which acts as an NO-carrying agent and nitrosates anilines or ureas.

The chemical follow-up reactions after one-electron oxidation of p-anisidine (PA), N-methyl-p-anisidine (MPA), and N-benzyl-p-anisidine (BPA) in acetonitrile (AN) were analyzed with a stopped-flow method utilizing the electron-transfer reaction with the tris(p-bromophenyl)amine (TBPA) cation radical. The reactions of these p-anisidine derivative cation radicals in AN were found to be faster than that of N,N-dimethyl-p-anisidine (DMPA) cation radical, which proceeds via the acid-base interaction between DMPA ?+ and DMPA. In addition, while the rate law of the decay reaction of DMPA?- was expressed as -d[DMPA?+]/ dt = k[DMPA?+]-[DMPA], that of PA?+ has been determined to be -d[PA?+]/dt = k[PA?+] 2[PA] when PA?- was generated in the presence of PA. On the other hand, in the case that PA?+ was quantitatively formed without PA via equimolar mixing with TBPA?+, the rate was determined to be -d[PA?+]/dt = k[PA?+] 2. Also, for the reactions of MPA?+ and BPA ?+, the rate laws were identical to those of PA ?+. From these results, the reaction mechanisms and the effects of the methyl groups on the reaction kinetics of the p-anisidine derivative cation radicals in AN were discussed.

GPR40 is one of the most prominent targets for the treatment of type 2 diabetes (T2DM), and has its role in insulin secretion via blood-glucose-dependent manner with a minimum risk of hypoglycemia. In order to discover novel antidiabetics bearing these benefits, we screened various derivatives with two distinct pharmacophores. Both series displayed potent agonistic activities for GPR40 in vitro functional assay. Through additional ADME and in vivo efficacy evaluations, we identified the potent hit candidate 2j as a novel GPR40 agonist.

Eighteen new 2-chloro-4-aminopyrimidine and 2,6-dimethyl-4-aminopyrimidine derivatives were synthesized and evaluated as tubulin polymerization inhibitor for the treatment of cancer. Among them, compounds 10, 17, 20 and 21 exhibited potent antiproliferative activities against five human cancer cell lines. Microtubule dynamics assay showed that compound 17 could effectively inhibit tubulin polymerization. Molecular docking studies were also carried out to understand the binding pattern. Further mechanism studies revealed that 17 could induce G2/M phase arrest, disrupt the organization of the cellular microtubule network and induce cell apoptosis and mitochondrial dysfunction.

The potential catalytic activity of selected C,N-chelated organotin(IV) compounds (e.g. halides and trifluoroacetates) for derivatization of both dimethyl carbonate (DMC) and diethyl carbonate (DEC) was investigated. Some tri-, di- and monoorganotin(IV) species (LCN(n-Bu)2SnCl (1), LCN(n-Bu)2SnCl.HCl (1a), LCN(n-Bu) 2SnI (2), LCNPh2SnCl (3), LCNPh 2SnI (4), LCN(n-Bu)SnCl2 (5), L CNSnBr3 (6) and [LCNSn(OC(O)CF 3)]2(mu-O)(mu-OC(O)CF3)2 (7)) bearing the LCN moiety (LCN = 2-(N,N-dimethylaminomethyl) phenyl-) were assessed as catalysts for reactions of both DMC and DEC with various substituted anilines. The catalytic activities of 4 and 7 for derivatization of DMC with p-substituted phenols were studied for comparison with the standard base K2CO3/Silcarbon K835 catalyst (catalyst 8). The composition of resulting reaction mixtures was monitored by multinuclear NMR spectroscopy, GC and GC-MS techniques. In general, catalysts 1, 3 and 7 exhibited the highest catalytic activity for all reactions studied, while some of them yielded selectively carbonates, carbamates, lactam or substituted urea.

Novel Leflunomide analogues were synthesized and evaluated in vivo against thioacetamide (TAA) induced liver fibrosis in rats. All the animals which were treated with the new analogues showed improved or comparable survival rates to those treated with Leflunomide. Animals which were treated with compounds 8d, 8e, 9 and 11 have shown improved liver parameters than Leflunomide treated animals. Histopathology of the liver has shown that compound 8a is the most active compound, which decreases fibrosis to a minimal level and compounds 8c, 8e and 11 are active compounds with fibrosis score 2-3 which is better than that of Leflunomide.

A new family of stereoconvergent cross-couplings of unactivated secondary alkyl electrophiles has been developed, specifically, arylamine-directed alkyl-alkyl Suzuki reactions. This represents the first such investigation to be focused on the use of alkyl chlorides as substrates. Structure- enantioselectivity studies are consistent with the nitrogen, not the aromatic ring, serving as the primary site of coordination of the arylamine to the catalyst. The rate law for this asymmetric cross-coupling is compatible with transmetalation being the turnover-limiting step of the catalytic cycle.
