  Compositional Persistence in a Multicyclic Network of Synthetic Replicators

  摘要：

  The emergence of collections of simple chemical entities that create self-sustaining reaction networks, embedding replication and catalysis, is cited as a potential mechanism for the appearance on the early Earth of systems that satisfy minimal definitions of life. In this work, a functional reaction network that creates and maintains a set of privileged replicator structures through auto- and cross-catalyzed reaction cycles is created from the pairwise combinations of four reagents. We show that the addition of individual preformed templates to this network, representing instructions to synthesize a specific replicator, induces changes in the output composition of the system that represent a network-level response. Further, we establish through sets of serial transfer experiments that the catalytic connections that exist between the four replicators in this network and the system-level behavior thereby encoded impose limits on the compositional variability that can be induced by repeated exposure to instructional inputs, in the form of preformed templates, to the system. The origin of this persistence is traced through kinetic simulations to the properties and inter-relationships between the critical ternary complexes formed by the auto- and cross-catalytic templates. These results demonstrate that in an environment where there is no continuous selection pressure the network connectivity, described by the catalytic relationships and system-level interactions between the replicators, is persistent, thereby limiting the ability of this network to adapt and evolve.

  分子识别：氢键的连接和断开，以带有简单受体的二聚体和高度缔合的一元羧酸为例

  摘要：

  具有混合的二酰胺部分的新受体（5）是简单的合成模型，其通过涉及吡啶氮，吡啶酰胺以及柔性脂族酰胺部分的三点氢键结合羧酸。这与仅形成两个点氢键的受体（6）相反。还报道了简单的吡啶酰胺（3）与许多二聚且高度缔合的单羧酸形成两个氢键的结合研究。与（3）相比，受体（9）显示出更高的与布洛芬的结合常数。

  Reactions of various heterocycles 1–6 with N-bromosuccinimide in the presence or absence of water have been studied for side chain versus ring bromination to afford some new and important heterocyclic synthons. Interestingly, the N-bromosuccinimide reaction in the presence of perchloric acid, a new condition, affords exclusively the new dibromo aminopicoline 1f, which is not obtained by other presently

  The new receptor (5) having mixed diamide moieties is a simple synthetic model which binds carboxylic acids by three point hydrogen bonds involving pyridine nitrogen, pyridine amide as well as the flexible aliphatic amide moieties. This is in contrast to the receptor (6) which makes only two point hydrogen bonds. Binding studies of the simple pyridine amide (3) making two hydrogen bonds with a number

  reaction of an amine bearing an amidopyridine recognition site and an aldehyde bearing a carboxylic acid recognition site affords an imine that is capable of directing its own formation through a dynamic covalent replication cycle. Additionally, the amine, formed by reduction of the replicating imine, is a more efficient catalyst for the formation of the replicating imine than the imine is a catalyst for
