Alumination of Si-KIT-6 materials with ordered three-dimensional (3D) structure were prepared by post-synthesis method with various Si/Al ratios. The catalysts were characterized by X-ray diffraction analysis (XRD), N-2 porosimetry and FT-IR spectra. The presence of framework and extra framework aluminium was predicted by Aluminium MAS NMR. The strength of the acid sites of the catalysts was studied by NH3-TPD acidity measurements. The morphology of mesoporous materials was studied by SEM and TEM observation. The metal content of the samples was investigated by ICP-OES. The prepared solid acid catalysts were applied for the multi-component synthesis of 1H-pyrazolo[1,2-]phthalazine-5,10-diones from the reaction of phthalhydrazide, malononitrile/ethylcyano acetate and aromatic aldehyde in ethanol under liquid phase conditions. Activities of the catalysts follow the order: Al-KIT-6 (33) > Al-KIT-6 (56) > Al-KIT-6 (81) > Al-KIT-6 (110) > Nafion-H > Amberlyst-15 >> HM (12) > H beta (8) > HY (4). The effects of reaction conditions and different catalysts have been studied. Various advantages associated with these protocols include effective catalysis, simple work-up procedure, short reaction times, high product yields, easy recovery and reusability of the catalysts.

Design of a new series of 1,3,4-oxadiazole derivatives was achieved in good yield via treatment of N-arylidene-2-(1-oxo-4-(4-phenoxyphenyl)phthalazin-2(1H)-yl)acetohydrazide with cerium (IV) ammonium nitrate as a catalyst. They can be formulated also using one-pot reaction of 2-(1-oxo-4-(4-phenoxyphenyl)phthalazin-2(1H)-yl)acetohydrazide, aromatic aldehyde and cerium (IV) ammonium nitrate in dichloromethane. The structural formulas of all synthesized products were elucidated based on their elemental and spectral analyses.

PbO nanoparticles were explored as a highly efficient, simple, cheap, and recyclable catalyst for the fast synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by means of a one-pot three-component reaction of phthalhydrazide, aromatic aldehyde, and malononitrile under solvent-free conditions at 80 A degrees C. Furthermore, nanosized PbO was prepared by the two conventional methods of planetary ball milling and dispersion of commercial PbO in n-octane, and their catalytic performances were compared with the commercial bulk PbO. The prepared nano-PbO via ball milling was described by SEM, TEM, XRD, EDX, and FT-IR spectroscopy. The present protocol conveyed major proficiencies such as the use of a reasonable and readily available catalyst, simple work-up and purification of products by nonchromatographic strategy, low reaction times, and enhanced yields under relatively environmental benign conditions. The heterogeneous catalyst was appropriately recyclable and could be reused for several times without loss of activity.

A series of 11-molybdo-1-vanadophosphoric acid supported on montmorillonite K-10 catalysts were prepared and characterized by FT-IR spectroscopy, thermal analysis, XRD, BET and SEM analysis techniques. Characterization data reveals the chemical immobilization of H4PMo11V1O40 catalyst on the montmorillonite K-10 support. The catalytic performance of synthesized catalysts was investigated for the synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives by one-pot three-component reaction of phthalhydrazide, dimedone and aromatic aldehydes under solvent-free conditions. Among different catalysts, 20% H4PMo11V1O40 supported on to montmorillonite K-10 showed the highest catalytic activity. Effect of reaction parameters such as catalyst loading, temperature and the nature of substituents on the aromatic ring of aldehydes were also evaluated. The protocol developed using H4PMo11V1O40/K-10 has several distinct advantages such as operational simplicity, short reaction time, high yield, reusable catalyst and preclusion of toxic solvent.

Treatment of patients with triple-negative breast cancer (TNBC) is challenging due to the absence of well-defined molecular targets and the heterogeneity of such disease. In our endeavor to develop potent isatin-based anti-proliferative agents, we utilized the hybrid-pharmacophore approach to synthesize three series of novel isatin-based hybrids 5a-h, 10a-h and 13a-c, with the prime goal of developing potent anti-proliferative agents toward TNBC MDA-MB-231 cell line. In particular, compounds 5e and 10g were the most active hybrids against MDA-MB-231 cells (IC50 = 12.35 +/- 0.12 and 12.00 +/- 0.13 mu M), with 2.37-and 2.44-fold increased activity than 5-fluorouracil (5-FU) (IC50 = 29.38 +/- 1.24 mu M). Compounds 5e and 10g induced the intrinsic apoptotic mitochondrial pathway in MDA-MB-231; evidenced by the reduced expression of the anti-apoptotic protein Bcl-2, the enhanced expression of the pro-apoptotic protein Bax and the up-regulated active caspase-9 and caspase-3 levels. Furthermore, 10g showed significant increase in the percent of annexin V-FITC positive apoptotic cells from 3.88 to 31.21% (8.4 folds compared to control).

The cynomolgus macaque is a non-human primate species widely used in drug metabolism studies. Despite the importance of genetic polymorphisms in cytosolic aldehyde oxidase (AOX) 1 in humans, genetic variants have not been investigated in cynomolgus or rhesus macaques. Genetic variants in AOX1 were identified and allele frequencies were assessed using the genomes of 24 cynomolgus and 8 rhesus macaques. The analysis identified 38 non-synonymous variants, some of which were unique to cynomolgus macaques (bred in Cambodia, Indochina, or Indonesia) or rhesus macaques, whereas many variants were shared by the two lineages. Among the variants observed at relatively high frequencies, eight were selected for functional analysis. Recombinant P605L and V1338I AOX1 variants showed substantially lower phthalazine and carbazeran oxidation activities than the wild-type AOX1 protein. In liver cytosolic fractions from cynomolgus and rhesus macaques genotyped for P605L and V1338I AOX1, groups of cytosolic fractions with P605L and/or V1338I AOX1 variants showed significantly lower phthalazine and carbazeran oxidation activities than the wild type. These results indicate that AOX1 is polymorphic in cynomolgus and rhesus macaques, just as it is in humans. Further investigation is needed to reveal the functional significance of these AOX1 variants in drug metabolism.
