  Trianion Synthon 方法对螺环杂环

  摘要：

  利用α-杂原子腈作为三阴离子合成子，通过双烷基化和还原环化方法构建了多种螺环杂环。该方法提供了获得各种环大小的杂原子取代螺环的途径，这些环大小在天然产物中发现并且在药物先导开发和优化中很重要。

  Substituted amine derivatives represented by the general formula ##STR1## wherein Q is -C-D-E- F-G-M- or -N-H-I-J-K-L- [C, D, E, F, G, H, I, J, K and L are each O, S, a carbonyl group, -CHR.sup.2 -, -R.sup.b = or -NR.sup.c - (R.sup.a, R.sup.b and R.sup.c are each H or a lower alkyl group), M and N are each an aromatic ring of 5-6 members optionally having a halogen, OH, LN, a lower alkyl group or a lower alkoxy group, provided that L is not O, S, or -NR.sup.c -]; R is a heterocyclic ring of 5-6 members; R.sup.1 is H, a lower alkyl group, a lower haloalkyl group, a lower alkenyl group, a lower alkynyl group or a cycloalkyl group; R.sup.2, R.sup.3, R.sup.4, R.sup.5 R.sup.6 and R.sup.7 are each H, a halogen or a lower alkyl group or two of them denote a single bond; R.sup.8 and R.sup.9 are each F, CF.sub.3 or a lower alkyl group or are a cycloalkane in combination thereof; and R.sup.10 is H, F, CF.sub. 3 an acetoxy group, a lower alkyl group or a lower alkoxy group. These compounds inhibit biosynthesis of cholesterol in mammals by inhibiting their squalene epoxidase, and thereby lower their blood cholesterol values. Therefore, these compounds are expected to be effective as an agent for treatment and prophylaxis of diseases caused by excess of cholesterol, for example, obesity, hyperlipemia and arteriosclerosis and heart and encephalic diseases accompanying them.

• Probing the active site of rat porphobilinogen synthase using newly developed inhibitors

  日期：2009.2

  The structurally related tetrapyrrolic pigments are a group of natural products that participate in many of the fundamental biosynthetic and catabolic processes of living organisms. Porphobilinogen synthase catalyzes a rate-limiting step for the biosyntheses of tetrapyrrolic natural products. In the present study, a variety of new substrate analogs and reaction intermediate analogs were synthesized, which were used as probes for studying the active site of rat porphobilinogen synthase. The compounds 1, 3, 6, 9, 14, 16, and 28 were found to be competitive inhibitors of rat porphobilinogen synthase with inhibition constants ranging from 0.96 to 73.04 mM. Compounds 7, 10, 12, 13, 15, 17, 18, and 26 were found to be irreversible enzyme inhibitors. For irreversible inhibitors, loose-binding inhibitors were found to give stronger inactivation. The amino group and carboxyl group of the analogs were found to be important for their binding to the enzyme. This study increased our understanding of the active site of porphobilinogen synthase.

• Trianion Synthon Approach to Spirocyclic Heterocycles
  作者：Matthew A. Perry、Richard R. Hill、Scott D. Rychnovsky

  DOI：10.1021/ol400788q

  日期：2013.5.3

  A variety of spirocyclic heterocycles have been constructed by a double-alkylation and reductive cyclization approach utilizing α-heteroatom nitriles as trianion synthons. The method provides access to heteroatom-substituted spirocycles in a variety of ring sizes that are found in natural products and are important in pharmaceutical lead development and optimization.
