potent, bioavailable ACAT inhibitor may have beneficial effects in the treatment of atherosclerosis by (i) reducing the absorption of dietary cholesterol, (ii) reducing the secretion of very low density lipoproteins into plasma from the liver, and (iii) preventing the transformation of arterial macrophages into foam cells. We have found that a mevalonate derivative 2, which contains a 4,5-diphenyl-1H-imidazol-2-yl

isothiocyanate, and p-toluenesulfonyl chloride were studied. The structures of the newly synthesized compounds were established on the basis of IR, 1H NMR, mass spectra, and elemental analyses. The antitumor activities of some selective compounds were examined against two cell lines as liver carcinoma cell line (HEPG-2) and human breast cancer cell line (MCF7). GRAPHICAL ABSTRACT

The radiation-sensitive composition and the negative working imageable element include a cationic IR absorber with tetraarylborate counteranion and an onium initiator with tetraarylborate counteranion. The use of these components provides high imaging sensitivity, good shelflife and high print run length.

Disclosed is a method for producing a metal particle dispersion wherein a metal compound is reduced by using carbodihydrazide represented by the formula (1) below or a polybasic acid polyhydrazide represented by the formula (2) below (wherein R represents an n-valent polybasic acid residue) in a liquid medium. By reducing the metal compound in the presence of a compound having a function preventing discoloration of the metal, there can be obtained a metal particle dispersion having excellent discoloration preventing properties. Metal particles produced by such methods have a uniform particle diameter and are excellent in dispersion stability. By using a conductive resin composition or conductive ink containing a metal particle dispersion obtained by such production methods, there can be formed a conductive coating film, such as a conductive circuit or an electromagnetic layer, having good characteristics.
本发明公开了一种生产金属颗粒分散液的方法,该方法通过在液体介质中使用下式 (1) 所代表的碳二酰肼或下式 (2) 所代表的多基酸多酰肼(其中 R 代表正价多基酸残基)还原金属化合物。通过在具有防止金属褪色功能的化合物存在下还原金属化合物,可获得具有优异防褪色性能的金属颗粒分散液。通过这种方法制得的金属颗粒具有均匀的颗粒直径和出色的分散稳定性。使用含有通过这种生产方法获得的金属颗粒分散体的导电树脂组合物或导电墨水,可以形成具有良好特性的导电涂膜,例如导电电路或电磁层。
