Correlation of the hydrogen-bond acceptor properties of nitrogen with the geometry of the Nsp 2 →Nsp 3 transition in R 1(X=)C–NR 2 R 3 substructures: reaction pathway for the protonation of nitrogen
Autor: S. E. Harris, C. M. Bird, R. S. Rowland, C. H. Schwalbe, Frank H. Allen
Publikováno v: Acta Crystallographica Section B Structural Science. 51:1068-1081
The non-bonded N...H interactions between N atoms of R 1 (X =)C-N(R 2 R 3 ) (R 2 ,R 3 = Csp 3 or H) substructures and the H atoms of N-H and O-H donors have been analysed using crystallographic data and ab initio molecular orbital calculations. A tot

Anti-depressant and anti-nociceptive effects of 1,4-benzodiazepine-2-ones based cholecystokinin (CCK(2)) antagonists
Autor: E, Lattmann, J, Sattayasai, P, Lattmann, D C, Billington, C H, Schwalbe, J, Boonprakob, W, Airarat, H, Singh, M, Offel, A, Staaf
Publikováno v: Drug discoveriestherapeutics. 1(1)
Various 1,4-benzodiazepines were synthesized around a Diazepam, Oxazepam and the n-propyl-1,4-benzodiazepine template. SAR studies of CCK(2) binding affinity were performed and selected examples of each series were tested in vivo in mice. In addition

Structural studies on bioactive compounds. Part 26. Hydrogen bonding in the crystal structure of the N-methylformamide solvate of the immunomodulatory agent 2-amino-5-bromo-6-phenylpyrimidin-4-one (bropirimine): implications for the design of novel anti-tumour strategies
Autor: M F, Stevens, C H, Schwalbe, N, Patel, E N, Gate, P K, Bryant
Publikováno v: Anti-cancer drug design. 10(3)
The immunomodulatory agent bropirimine crystallizes from N-methylformamide (NMF) as a triply hydrogen-bonded duplex in the manner of a Watson-Crick guanine:cytosine base pair. The stoichiometry of the solvate is bropirimine:NMF (2:1) and all NMF mole

Structural studies on bio-active compounds. Part 18. Crystal structure and molecular modelling of methyl 4-(3-ethyl-3-hydroxymethyltriazen-1-yl) benzoate
Autor: G, Chopra, C H, Schwalbe
Publikováno v: Anti-cancer drug design. 6(5)
The title compound is an isomer, differing only by the shift of a methyl group, of the anti-cancer agent ethyl 4-(3-hydroxymethyl-3-methyltriazen-1-yl) benzoate; yet its half-life at physiological pH is only one-third as long. It forms crystals with

Autor: C E, Sansom, C A, Laughton, S, Neidle, C H, Schwalbe, M F, Stevens
Publikováno v: Anti-cancer drug design. 5(3)
Molecular mechanics modelling was carried out on the antimicrobial aromatic diamidine, pentamidine, bound to the minor groove of several AT-rich DNA octamers. The pentamidine molecule was found to span four base pairs, with its highly charged amidini

Autor: A S, Clark, M F, Stevens, C E, Sansom, C H, Schwalbe
Publikováno v: Anti-cancer drug design. 5(1)
The structural and electronic properties of the major groove-binding anti-tumour imidazotetrazinones, mitozolomide and temozolomide were studied using molecular orbital techniques. Structure-activity relationships of mitozolomide derivatives emphasiz
