“…The second fragment, the C17 side chain (IV) typical of cholesterol and related steroids, is acyclic. In both cases the results of manual conformational classifications (Taylor, 1989;Duax, Griffin, Rohrer & Weeks, 1980) were available for comparison.…”

“…The manual survey of Taylor (1989) was repeated. There were 36 entries in the July 1989 release of the CSD containing (I) constrained to have single intra-annular bonds (bond type = 1), with no fusion or bridging of the fragment (no cyclic routes emanating from the defined fragment), and with error-free atomic coordinates available.…”

A unified computational procedure is described for the identification of conformational subgroups for a chemical fragment from crystal structure data. Fragment conformations are defined by N, torsion angles for Nj occurrences of the fragment in the Cambridge Structural Database. Subdivision of this multivariate data set is performed by a choice of clustering algorithms (single-linkage, complete-linkage, JarvisPatrick). Both asymmetric and symmetric fragments are handled routinely. The algorithms yield optimum superposition of a given conformation in a single cluster and place discrete clusters into a single asymmetric unit of conformational space. The unified procedure generates graphical and numerical indicators of clustering efficiency: (i) principal-component plots of the optimally superimposed data set, (ii) a simple statistical summary for each cluster, (iii) measures of intracluster shape and size, (iv) details of intercluster separations. Major clusters are ranked in order of decreasing population and the 'most representative fragment' (MRF: the fragment of the data set which is closest to the cluster centroid) is identified in each case. Atomic coordinates for the MRF's may be output for use as conformational alternatives in model building. The complete procedure is successfully applied to the automated conformational analysis of two very different systems, the cyclic 1-azacycloheptane moiety and the acyclic Cx7 side chain typical of cholesterol and related steroids.

Andrew McRae examines the relation between literature and politics at a pivotal moment in English history. He argues that the most influential and incisive political satire in this period may be found in manuscript libels, scurrilous pamphlets and a range of other material written and circulated under the threat of censorship. These are the unauthorised texts of early Stuart England. From his analysis of these texts, McRae argues that satire, as the pre-eminent literary mode of discrimination and stigmatisation, helped people make sense of the confusing political conditions of the early Stuart era. It did so partly through personal attacks and partly also through sophisticated interventions into ongoing political and ideological debates. In such forms satire provided resources through which contemporary writers could define new models of political identity and construct new discourses of dissent. This book wil be of interest to political and literary historians alike.
