  Preparation and antigenic property of 3-dehydrolithocholylglycine 3-(O-carboxymethyl)oxime-bovine serum albumin conjugate

  摘要：

  The preparation and antigenic property of 3-dehydrolithocholyglycine-bovine serum albumin (BSA) conjugate in which the hapten is linked to the carrier protein through an (O-carboxymethyl) oxime bridge at the C-3 position on the steroid nucleus is described. Antibody raised against antigen in the rabbit possessed high titer and specificity to lithocholylglycine, exhibiting no significant cross-reaction with free lithocholic acid or lithocholyltaurine.

  against T. brucei rhodesiense with IC50s below 2.0 μM and SI between 2.7 and 29.3. Four primary amine derivatives of noscapine and five isothiocyanate derivatives exhibited antiplasmodial activity with IC50s in the range of 1.1-2.7 µM and SI values between 1.1 and 14.5. The isothiocyanate derivative 7c showed against T. cruzi with an IC50 value of 1.9 µM and SI 4. Molecular docking and ADMET studies

  We report the visible light photocatalytic cleavage of trityl thioethers or ethers under pH-neutral conditions. The method results in the formation of the respective symmetrical disulfides and alcohols in moderate to excellent yield. The protocol only requires the addition of a suitable photocatalyst and light rendering it orthogonal to several functionalities, including acid labile protective groups

  我们报告了在 pH 中性条件下三苯甲基硫醚或醚的可见光光催化裂解。该方法导致以中等到极好的收率形成相应的对称二硫化物和醇。该协议只需要添加合适的光催化剂和光使其与多种功能正交，包括酸不稳定保护基团。相同的条件可用于直接将三苯甲基保护的硫醇转化为不对称的二硫化物或硒硫化物，并在固相有机合成中裂解三苯甲基树脂。

  A gold-catalyzed, nucleophile-controlled cascade reaction of N-(2-azidophenyl-ynyl)methanesulfonamides with nitriles and water is described that provides structurally diverse 5H-pyrimido[5,4-b]indoles and 2-benzylidene-3-indolinones in good to excellent yields. Mechanistic studies indicate that the β-sulfonamido-α-imino gold carbene is the key intermediate which is generated through the gold-catalyzed
